Die-cast components made from aluminum and magnesium alloys are becoming increasingly important in the automotive industry. They help reduce vehicle weight and improve overall efficiency. At the same time, quality requirements are rising. Every component must be complete and free of defects. Otherwise, functional failures, safety risks, or costly downstream damage may occur. Critical structures such as sprues, casting burrs, runners, channels, and feeders must therefore be inspected reliably.
Limits of conventional inspection technology
Many manufacturers still rely on traditional sensors such as light barriers, inductive sensors, or reflective photoelectric sensors. These sensors must be positioned very close to the hot workpiece. This exposes them to high thermal stress. There is also a risk of collisions with the parts. Another drawback is the high effort required during product or tool changes. Sensors often need to be repositioned, adjusted, or expanded. These changes lead to additional downtime and higher maintenance effort.
High product variety and challenging surfaces
Die-cast components differ greatly in shape, size, and surface properties. Some parts have shiny, dark, or highly reflective surfaces. These characteristics make reliable optical inspection more difficult. Manufacturers therefore need a flexible inspection system. It must detect and evaluate different component geometries automatically. At the same time, it should operate without mechanical adjustments and remain reliable under changing production conditions.
Application
An automated inspection system from VisionTools solves this challenge. The system integrates directly into the production line and captures the geometry of each cast component without contact. At the center of the solution is an Ensenso N35 3D camera. It captures precise spatial data from a safe distance. The system uses this data to verify the completeness and condition of all relevant component structures.
Precise 3D capture from a safe distance
Depending on the component size, a robot moves the workpiece step by step in front of the camera. This allows the system to capture all relevant areas. Image acquisition and analysis take only a few seconds per inspection position. As a result, the inspection process fits seamlessly into the production workflow without slowing down throughput. The camera generates a detailed 3D point cloud of the component geometry. The software compares this data with stored reference models. If deviations occur, the system immediately identifies and reports them. Defective parts can therefore be removed early. This prevents potential damage to tools or machines.
Flexible inspection of different component variants
The system supports a wide range of product variants. Operators can manage product and tool changes entirely through software. No mechanical adjustment of the sensors is required. The software simply compares the stored inspection features with the current measurement data. This approach significantly reduces setup times and production interruptions.
Reliable results on challenging surfaces
The Ensenso N35 uses projected texture stereo vision. An integrated projector casts artificial patterns onto the surface of the workpiece. Two cameras capture these patterns from different perspectives. The system then calculates a precise 3D representation using triangulation. Additional technologies such as FlexView further improve measurement accuracy. The system combines several images with different projection patterns to generate highly reliable data. This method produces stable results even on shiny, dark, or reflective surfaces. This capability is particularly valuable for die-cast components with demanding material properties.
Outlook
Camera-based 3D inspection enables reliable, contactless quality control directly within the production process. It significantly reduces defect rates and improves overall process stability. At the same time, the system helps prevent downtime in die-casting machines. It detects incomplete mold emptying at an early stage and removes faulty parts before they cause problems. Manufacturers benefit from lower production costs and higher system availability.
The flexible, software-driven architecture also opens new opportunities. The system can easily adapt to different components and production scenarios. This makes it suitable not only for die casting but also for other metalworking processes or industries that require fast and precise inspection of complex geometries.
Overall, the solution demonstrates how modern 3D vision technology strengthens quality assurance in industrial production. At the same time, it increases efficiency, improves safety, and reduces operating costs.

When the website is accessed, a cookie with the settings information is stored on the user's end device so that the query regarding consent does not have to be made on a subsequent visit.
The cookie is required to obtain the user's legally compliant consent.
The user can prevent or stop the installation of cookies by changing the settings in their browser.
We use so-called cookies on our website. Cookies are small text files or other storage technologies that are placed and stored on your end device by the Internet browser you use. These cookies are used to process certain information from you, such as your browser or location data or your IP address, on an individual basis.
This processing makes our website more user-friendly, effective and secure, as the processing enables, for example, the reproduction of our website in different languages or the offer of a shopping basket function.
The legal basis for this processing is Art. 6 para. 1 lit. b) GDPR, insofar as these cookies process data for contract initiation or contract fulfilment.
If the processing does not serve to initiate or fulfil a contract, our legitimate interest lies in improving the functionality of our website. The legal basis in this case is Art. 6 para. 1 lit. f) GDPR.
These session cookies are deleted when you close your Internet browser.
b) Third-party cookies
Our website may also use cookies from partner companies with whom we work for the purposes of advertising, analysing or the functionalities of our website.
Please refer to the following information for details, in particular the purposes and legal basis for processing such third-party cookies.
c) Removal option
You can prevent or restrict the installation of cookies by changing the settings of your Internet browser. You can also delete cookies that have already been saved at any time. However, the steps and measures required for this depend on the specific Internet browser you are using. If you have any questions, please use the help function or documentation of your Internet browser or contact its manufacturer or support. In the case of so-called Flash cookies, however, processing cannot be prevented via the browser settings. Instead, you must change the settings of your Flash player. The steps and measures required for this also depend on the specific Flash player you are using. If you have any questions, please also use the help function or documentation of your Flash player or contact the manufacturer or user support. For security reasons, we advise against using a Flash player.
However, if you prevent or restrict the installation of cookies, this may mean that not all functions of our website can be used to their full extent.
If you contact us via contact form or email, the data you provide will be used to process your enquiry. The provision of the data is necessary for processing and answering your enquiry - without it we cannot answer your enquiry or can only answer it to a limited extent.
The legal basis for this processing is Art. 6 para. 1 lit. b) GDPR.
Your data will be deleted if your enquiry has been conclusively answered and the deletion does not conflict with any statutory retention obligations, such as in the case of any subsequent contract processing.
If you register for our free newsletter, the data requested from you for this purpose, i.e. your email address and - optionally - your name and address, will be transmitted to us. At the same time, we store the IP address of the Internet connection from which you access our website as well as the date and time of your registration. As part of the further registration process, we will obtain your consent to send you the newsletter, describe the content in detail and refer you to this privacy policy. We use the data collected in this process exclusively for sending the newsletter - in particular, it is therefore not passed on to third parties.
The legal basis for this is Art. 6 para. 1 lit. a) GDPR.
You can revoke your consent to receive the newsletter at any time with effect for the future in accordance with Art. 7 para. 3 GDPR. All you have to do is, inform us of your cancellation or click on the unsubscribe link contained in every newsletter.
We offer you the opportunity to apply for a job with us via our website. For these digital applications, we collect and process your applicant and application data electronically to handle the application process.
The legal basis for this processing is Section 26 (1) sentence 1 BDSG in conjunction with Art. 88 (1) GDPR. Art. 88 para. 1 GDPR.
If an employment contract is concluded after the application procedure, we will store the data you submitted during the application in your personnel file for the purpose of the usual organisational and administrative process - of course in compliance with further legal obligations.
The legal basis for this processing is also Section 26 para. 1 sentence 1 BDSG in conjunction with Art. 88 para. 1 GDPR. Art. 88 para. 1 GDPR.
If an application is rejected, we automatically delete the data transmitted to us within a maximum of two months after notification of the rejection. However, the data will not be deleted if the data requires longer storage of up to four months or until the conclusion of legal proceedings due to legal provisions, e.g. due to the burden of proof under the AGG.
In this case, the legal basis is Art. 6 para. 1 lit. f) GDPR and Section 24 para. 1 no. 2 BDSG. Our legitimate interest lies in legal defence or enforcement.
If you expressly consent to your data being stored for a longer period of time, e.g. for your inclusion in a database of applicants or interested parties, the data will be processed further on the basis of your consent. The legal basis is then Art. 6 para. 1 lit. a) GDPR. However, you can of course revoke your consent at any time in accordance with Art. 7 para. 3 GDPR by making a declaration to us with effect for the future.
For technical reasons, in particular to ensure a secure and stable Internet presence, data is transmitted to us or to our web space provider by your Internet browser. With these so-called server log files, the type and version of your Internet browser, the operating system, the website from which you have switched to our Internet presence (referrer URL), the website(s) of our Internet presence that you visit, the date and time of the respective access and the IP address of the Internet connection from which our Internet presence is used are collected, among other things.
The data collected in this way is stored temporarily, but not together with other data about you.
This storage takes place on the legal basis of Art. 6 para. 1 lit. f) GDPR. Our legitimate interest lies in the improvement, stability, functionality and security of our website.
The data will be deleted after seven days at the latest, unless further storage is required for evidence purposes. Otherwise, the data is excluded from deletion in whole or in part until an incident has been finally clarified.
This website is hosted by the German provider Strato. Strato AG is a processor within the meaning of Art. 28 of the GDPR and has concluded a corresponding ‘order processing contract’ (AVV) with us: https://www.strato.de/agb/avv/
Strato hosts all websites, including ours, exclusively on web servers in Germany, so that the GDPR applies without restriction. Details on the handling of personal data can be found in Strato AG's privacy policy: https://www.strato.de/datenschutz/
The legal basis for data processing by Strato AG results from Art. 6 I lit. a GDPR and further paragraphs of the GDPR.
The data transmitted by you to utilise our range of goods and/or services is processed by us for the purpose of contract processing and is required in this respect. Conclusion and fulfilment of the contract are not possible without the provision of your data.
The legal basis for the processing is Art. 6 para. 1 lit. b) GDPR.
We delete the data once the contract has been fully processed, but must observe the retention periods under tax and commercial law.
As part of the contract processing, we pass on your data to the transport company commissioned with the delivery of goods or to the financial service provider, insofar as the transfer is necessary for the delivery of goods or for payment purposes.
The legal basis for the transfer of data is then Art. 6 para. 1 lit. b) GDPR.

LinkedIn is a service of LinkedIn Ireland Unlimited Company, Wilton Plaza, Wilton Place, Dublin 2, Ireland, a subsidiary of LinkedIn Corporation, 1000 W. Maude Avenue, Sunnyvale, CA 94085, USA.
In this respect, we would like to point out that there is a possibility that user data may be processed outside the European Union, in particular in the USA. This may result in increased risks for users in that, for example, subsequent access to user data may be made more difficult. We also have no access to this user data. The access option lies exclusively with LinkedIn.
We maintain an online presence on YouTube to present our company and our services and to communicate with customers/prospects. YouTube is a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, a subsidiary of Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA.

The provider uses a link on the website to the social networks listed below.
The legal basis for this is Art. 6 para. 1 lit. f GDPR. The provider has a legitimate interest in improving the quality of use of the website.
The plugins are integrated via a linked graphic. Only by clicking on the corresponding graphic is the user redirected to the service of the respective social network.
Once the customer has been redirected, the respective network collects information about the user. This is initially data such as IP address, date, time and page visited. If the user is logged into their user account on the respective network during this time, the network operator may be able to assign the information collected about the user's specific visit to the user's personal account. If the user interacts via a ‘Share’ button of the respective network, this information can be stored in the user's personal user account and published if necessary. If the user wants to prevent the collected information from being directly assigned to their user account, the user must log out before clicking on the graphic. It is also possible to configure the respective user account accordingly.
The following social networks are linked by the provider:
We use Google Analytics on our website. This is a web analysis service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, hereinafter referred to as ‘Google’.
The Google Analytics service is used to analyse the usage behaviour of our website. The legal basis is Art. 6 para. 1 lit. f) GDPR. Our legitimate interest lies in the analysis, optimisation and economic operation of our website.
Usage and user-related information, such as IP address, location, time or frequency of visits to our website, is transmitted to a Google server in the USA and stored there. However, we use Google Analytics with the so-called anonymisation function. This function allows Google to truncate the IP address within the EU or EEA.
The data collected in this way is in turn used by Google to provide us with an analysis of the visit to our website and the usage activities there. This data can also be used to provide other services related to the use of our website and the use of the Internet.
Google states that it will not associate your IP address with any other data. In addition, Google keeps under:
a so-called deactivation add-on along with further information on this. This add-on can be installed with the most common Internet browsers and offers you further control over the data that Google collects when you visit our website. The add-on informs the JavaScript (ga.js) of Google Analytics that information about your visit to our website should not be transmitted to Google Analytics. However, this does not prevent information from being transmitted to us or to other web analysis services. You can of course also find out whether and which other web analysis services we use in this privacy policy.
We use Google Maps on our website to display our location and to provide directions. This is a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, hereinafter referred to as ‘Google’.
In order to enable the display of certain fonts on our website, a connection to the Google server in the USA is established when our website is accessed.
If you call up the Google Maps component integrated into our website, Google stores a cookie on your end device via your Internet browser. Your user settings and data are processed in order to display our location and provide directions. We cannot rule out the possibility that Google uses servers in the USA.
If you have given your consent for this processing, the legal basis is Art. 6 para. 1 lit. a GDPR. The legal basis may also be Art. 6 para. 1 lit. f GDPR. Our legitimate interest lies in optimising the functionality of our website.
The connection to Google established in this way enables Google to determine from which website your enquiry has been sent and to which IP address the directions are to be transmitted.
If you do not agree to this processing, you have the option of preventing the installation of cookies by making the appropriate settings in your Internet browser. Details on this can be found above under ‘Cookies’.
In addition, the use of Google Maps and the information obtained via Google Maps is governed by the Google Terms of Use https://policies.google.com/terms?gl=DE&hl=de and the Terms and Conditions for Google Maps https://www.google.com/intl/de_de/help/terms_maps.html.
We use “Vimeo” on our website to display videos. This is a service provided by Vimeo, LL C, 555 West 18 th Street, New York, New York 10011, USA, hereinafter referred to as “Vimeo”.
Some of the user data is processed on Vimeo servers in the USA.
If you have given your consent for this processing, the legal basis is Art. 6 para. 1 lit. a GDPR. The legal basis may also be Art. 6 para. 1 lit. f GDPR. Our legitimate interest lies in improving the quality of our website.
If you visit a page of our website in which a video is embedded, a connection to the Vimeo servers in the USA is established to display the video. For technical reasons, it is necessary for Vimeo to process your IP address. In addition, the date and time of your visit to our website are also recorded.
If you are logged in to Vimeo at the same time as you visit one of our websites in which a Vimeo video is embedded, Vimeo may assign the information collected in this way to your personal user account there. If you wish to prevent this, you must either log out of Vimeo before visiting our website or configure your Vimeo user account accordingly.
Vimeo uses the web analysis service Google Analytics for the purpose of functionality and usage analysis. Google Analytics stores cookies on your end device via your Internet browser and sends information about the use of our Internet pages in which a Vimeo video is embedded to Google. It cannot be ruled out that Google will process this information in the USA.
If you do not agree to this processing, you have the option of preventing the installation of cookies by making the appropriate settings in your Internet browser. Details on this can be found above under “Cookies”.
The legal basis is Art. 6 para. 1 lit. f) GDPR. Our legitimate interest lies in the quality improvement of our website and in the legitimate interest of Vimeo to statistically analyze user behavior for optimization and marketing purposes.
We use YouTube on our website. This is a video portal of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, hereinafter referred to as “YouTube”.
We use YouTube in connection with the “extended data protection mode” function in order to be able to show you videos. If you have given your consent for this processing, the legal basis is Art. 6 para. 1 lit. a GDPR. The legal basis may also be Art. 6 para. 1 lit. f GDPR. Our legitimate interest lies in improving the quality of our website. According to YouTube, the “Enhanced Privacy Mode” function means that the data described in more detail below is only transmitted to the YouTube server when you actually start a video.
Without this “extended data protection mode”, a connection to the YouTube server in the USA is established as soon as you access one of our web pages on which a YouTube video is embedded.
This connection is necessary in order to be able to display the respective video on our website via your Internet browser. In the course of this, YouTube will at least record and process your IP address, the date and time and the website you have visited. In addition, a connection is established to Google's “DoubleClick” advertising network.
If you are logged in to YouTube at the same time, YouTube will assign the connection information to your YouTube account. If you wish to prevent this, you must either log out of YouTube before visiting our website or make the appropriate settings in your YouTube user account.
For the purpose of functionality and analysis of user behavior, YouTube permanently stores cookies on your end device via your Internet browser. If you do not agree to this processing, you have the option of preventing the storage of cookies by changing the settings in your Internet browser. You can find more information on this above under “Cookies”.
Google provides further information about the collection and use of data as well as your rights and protection options in this regard in the privacy policy available at
If you subscribe to our company's newsletter, the data in the respective input mask will be transmitted to the controller. Subscription to our newsletter takes place in a so-called double opt-in procedure. This means that after registering, you will receive an email asking you to confirm your registration. This confirmation is necessary so that no-one can register with other people's email addresses. When registering for the newsletter, the user's IP address and the date and time of registration are stored. This serves to prevent misuse of the services or the email address of the person concerned. The data is not passed on to third parties. An exception is made if there is a legal obligation to pass on the data. The data is used exclusively for sending the newsletter. Subscription to the newsletter can be terminated by the data subject at any time. Consent to the storage of personal data can also be revoked at any time. There is a corresponding link for this purpose in every newsletter. The legal basis for the processing of data after registration for the newsletter by the user is Art. 6 para. 1 lit. a) GDPR if the user has given consent. The legal basis for sending the newsletter as a result of the sale of goods or services is Section 7 (3) UWG
Description and purpose: We use rapidmail to send newsletters. The provider is rapidmail GmbH, Wentzingerstraße 21, 79106 Freiburg, Germany. Among other things, rapidmail is used to organize and analyse the sending of newsletters. The data you enter for the purpose of subscribing to the newsletter is stored on rapidmail's servers in Germany. If you do not wish to be analyzed by rapidmail, you must unsubscribe from the newsletter. For this purpose, we provide a corresponding link in every newsletter message. For the purpose of analysis, the emails sent with rapidmail contain a so-called tracking pixel, which connects to the rapidmail servers when the email is opened. In this way, it can be determined whether a newsletter message has been opened. We can also use rapidmail to determine whether and which links in the newsletter message have been clicked on. Optionally, links in the email can be set as tracking links, with which your clicks can be counted.
Legal basis: The legal basis for data processing is Art. 6 para. 1 lit. a) GDPR.
Recipient: The recipient of the data is rapidmail GmbH.
Transfer to third countries: Data will not be transferred to third countries.
Duration: The data stored by us as part of your consent for the purpose of the newsletter will be stored by us until you unsubscribe from the newsletter and deleted from both our servers and the servers of rapidmail after you unsubscribe from the newsletter. Data stored by us for other purposes (e.g. email addresses for the member area) remain unaffected by this.
Revocation option: You have the option of revoking your consent to data processing at any time with effect for the future. The legality of the data processing operations that have already taken place remains unaffected by the revocation.
