Raw part treatment
and testing

At ACTech, we are keen to go the extra mile with you. This is why our commitment to your part is far from over following casting. Each raw part undergoes comprehensive post-treatment and testing. As part of this we work according to your individual specifications and upon request, draw up extensive test documentation.

  • Wide range of raw part post-treatments performed in-house 

  • Extensive material and workpiece testing 

  • Documented raw part testing

Treatment of raw parts at ACTech

Straight to the target without distractions – when it comes to batch-comparable parts, ACTech takes the direct route. For this reason, we consistently develop our process chain and take care of both the production of your prototype and downstream post-processing. With ACTech, you get all work steps from a single source – for more reliability, speed and quality with each and every part. Our track record speaks for itself: more than 230,000 prototypes in metal and customers from 37 countries – this is expertise you can rely on.

 

We provide the complete range of standard and special machining for the treatment of raw parts, and deburring, blasting and polishing of castings are the basics always included. You'd like more extras? Heat treatment and hot isostatic pressing (HIP) to improve material properties, abrasive flow machining for improved surface roughness on channel surfaces, construction welding as well as impregnating, painting and coating castings – simply tell us which treatment you need for your raw part and we'll get it done.

  • Highest standard 
    Cleaning, fine cleaning, blasting, shock wave treatment 

  • Individual extras 
    Heat treatment, HIP, abrasive flow machining, painting, coating, impregnating 

  • Maximum time savings 
    All post-treatment options from a single source

Testing of raw parts at ACTech

Quality is one of our top priorities! For this reason no part leaves our facilities without being tested. We carry out extensive material and workpiece testing before a raw part is shipped or machined. This guarantees you maximum reliability in terms of quality and also saves a great deal of time, because our quality experts test your raw part directly on our premises. Depending on your needs, your parts undergo a leak test and/or crack test. We also have the necessary equipment in-house for X-ray, ultrasonic and endoscopic testing.

 

A fixed item on our to-do list is visual inspection and optical measurement – these test methods are standard for us and are performed on all castings. The same applies to the chemical analysis of the melt – after all, the material of your part should also be of premium quality. If required, we also analyze the microstructure of metallic materials using metallography and non-destructively test the hardness on the casting as well as the mechanical properties on separately cast test bars. All results of the analyses and tests are documented in detail in a test certificate.

  • Materials testing 
    Chemical analysis, mechanical properties/hardness testing, metallography 

  • Workpiece testing 
    Leak test, crack test, X-ray/ultrasonic/CT test, visual inspection/endoscopy, optical measurement 

  • Documentation
    Extensive test certificates as an integral part of project documentation

Tailored to your needs!

Do you have special requirements for the test procedures on your parts, or would you like us to implement a special technology for post-treating your raw parts? We are motivated by your needs – which is why we are always on the lookout for new solutions to tailor our services even more specifically to your wishes. A very recent example: abrasive flow machining, a special post-treatment method performed for improved surface quality, and carried out by only very few foundries. With us though this is part of our standard range of services – at the request of many customers.

FAQ

Are all cast or M3DP parts tested to ensure that they are free of molding material or powder?

Are all cast or M3DP parts tested to ensure that they are free of molding material or powder?

At ACTech all parts are initially cleaned according to needs, e.g. by blowing with compressed air, shock wave technology, blasting technology, thermal treatment in the furnace or by a combination of various methods. Certified testing personnel subject each metal part to at least one visual inspection with particular attention to mold material and material residues, surface defects, etc. The internal geometries of parts are also tested by means of endoscopy, the diameter of the endoscope ranging from 2.4 to 8 mm.

How is the tightness of a casting ensured with regard to gases and liquids?

How is the tightness of a casting ensured with regard to gases and liquids?

In most cases we perform the leak test as an underwater test using a compressed air bubble test up to approx. 1.5 bar. Depending on the geometry of the part, deviations from standard are always possible. An optimization of tightness can be achieved by the impregnating of parts.

Can castings be heat treated according to requirements?

Can castings be heat treated according to requirements?

Aluminum castings can be professionally treated at ACTech, for example with a T6 treatment, in e.g. a semi-automatic heat treatment facility. Steel and iron castings can undergo a wide variety of heat treatments in various furnaces, for example stress relief annealing, normalizing, solution annealing or further treatments upon customer request in accordance with the requirements or the delivery condition. Most heat treatments can be recorded with the appropriate technology and thus also documented. Heat treatment under inert gas atmosphere is also possible at ACTech.
