Insight into the modern technologies and machines used in toolmaking

Multi-axis CNC milling machines/turn-mill center: We use computer-controlled machines to mill precise mold cores and cavities from metal blocks. This helps us to achieve increased precision and efficiency in our production process.

Grinding machines: In our production process, grinding machines refine the surfaces of the mold cores and cavities for a high-precision fit. The use of these machines ensures first-class surface quality and meets our quality standards.

Lathes: We use lathes to produce cylindrical parts and threads that are required in injection molds. This enables us to ensure the precise production of components.

3D printer: We use 3D printing to produce specific tool inserts with conformal cooling systems. In this way, we achieve more precise temperature control of the tool along the mold contour.

CAD/CAM software: We use computer-aided design (CAD) and computer-aided manufacturing (CAM) software to create 3D models of the molds and program the machines for production.

Hardness testers: We use hardness testers to ensure that the manufactured tool parts have the required hardness.

Surface roughness measuring device: We do not compromise on quality and use special measuring devices to measure the required surface roughness.

Measuring and testing equipment: We use precise measuring instruments (CMM) and optical measuring systems to ensure that the molds produced meet the specified tolerances.

Polishing machines: We use polishing machines to polish the surfaces of the molds and ensure that the manufactured parts have a smooth surface.

Demolding systems: We use automated demolding systems to efficiently remove the manufactured parts from the molds, thereby increasing production output.
