// What defines us

Technical culture. Smart manufacturing. Own technology.

Traceability, automation, engineering — and a team that enjoys what they do.

Capabilities

Five processes.
One single integrated operation.

We design the mold, inject the part, overmold on copper, assemble and validate — all in-house. Part-level traceability.

// 01

Plastic Injection Molding

AAA plastic injection for all types of components; automotive, structural, precision. We mold any project from 100 to 300 tons.

Vertical Injection Molding

Our focus is on overmolding of copper busbars, metal components, cables and electronic components for automotive power systems, dielectric sealing, voltage hold-up, robotic positioning and part validation and testing directly from the machine.

2K · 3K Injection Molding

Double and triple multi-material injection for all types of components. We combine rigid with TPE for soft-touch, 2K decoration and geometries with two durometers without secondary operations. The part comes out ready, with Class A finishes where required.

Micro Injection Molding

A 10-ton clamping force machine dedicated exclusively to high technical complexity components. The small-diameter screw guarantees a first-in, first-out (FIFO) system for barrel material: each cycle processes fresh material, preventing thermal degradation and ensuring stable mechanical properties and color part to part.
