Product optimisation to reduce costs and improve functionality

Our team of experts helps you optimise product design by taking into account all customer requirements, technical requirements of the product, and limitations of the thermoplastic used. Our optimisation method enables better utilisation of materials, lower tool production costs, increased efficiency of production processes, and reduced errors and waste in production.

Computer simulations of injection moulding of thermoplastics and 3D printing of prototypes

To ensure the highest quality and precision of the process, we perform advanced computer simulations of injection moulding of thermoplastic materials. These simulations enable accurate prediction of material behaviour under various conditions and ensure optimal quality of the final product. We also perform 3D printing of prototypes from various materials, which enables quick testing and adjustment of designs before the start of production. With this process, we shorten the development time and increase the quality of the final products.

FAQ about Product Development

High-quality product development is the foundation for cost-efficient production, stable processes, and consistent quality.


Product development is based on detailed project analysis, correct material selection, and design optimization. Prototypes are produced and tested before final mold design.

Absolutely. All products are designed for stable, repeatable, and scalable serial production.

Yes. We are often involved in the early development stages to achieve optimal technical, cost, and lead-time solutions.

Proper mold design significantly extends tool lifetime, reduces maintenance requirements, and minimizes production downtime.

Yes. We use advanced mold flow simulations to optimize filling, cooling, warpage, and overall part quality.
