Place your trust in our team of experts, who will work with you to transform your design from a simple concept into a functional prototype and mold manufacturing, efficiently and hassle-free, ensuring you get the high-quality product you need.
No matter what stage your project is at, we can step in at any of these three points to adapt to your needs
If you can imagine it, we can make it a reality:
- DESIGN: Start your project with a discussion with our talented in-house design team. In this consultation, we identify the crucial aspects of your design. We can work from complete CAD models, simple sketches, or even just a sample of your components.
- DEVELOPMENT: Then, we will technically design the mold and create a one-off pre-production sample using 3D printing. We offer you the opportunity to see and feel what your final product will look like and how it will function, giving you the chance to test and optimize the design before moving on to the mold manufacturing stage.
- MANUFACTURING: Finally, we proceed with the production of the injection mold and the first authentic samples. Once approved, we begin in-house production of the required volume.
