“all in” at ACTech means: having all, mastering all, giving all, maintaining all. That’s why we have always relied on in-house solutions. All casting and CNC machining processes related to rapid prototyping are carried out in-house, right up to the ready-to-install part. Our “all in” concept is the basis for our practice of controlling all production processes ourselves and for our ability to realise extremely fast cycle times. This makes us more independent, more reliable and faster than others. Ultimately, it is this concept in combination with our experience from more than 25,000 different prototyping projects that convinces our customers to go “all in” with us time and again.

High Speed Workflow

“I need a perfect, ready-to-install prototype, quickly. Preferably yesterday!” However, because our mission never changes, our factory is changing all the time. We undertake regular inspections of new technologies and equipment. We are constantly optimizing our work flows to achieve the highest quality and the best use of time. How and using what methods can we speed up prototype manufacturing? What tools and strategies can we use to further reduce throughput times? How can we best support our customers? …we regularly find answers to questions like these and implement the appropriate solutions. Our effectiveness is another reason our customers keep going “all in” with us. 


To choose the right casting technology we need the following information:

  • Quantity of parts
