One partner for the whole part, designed, made and tested.

Croslynk Engineering House runs simulation, materials, tooling, manufacturing and testing for elastomer components under one roof. What leaves our floor has already passed its test.

01Simulation Services

Prove the part on screen first.

We fit a hyperelastic model to your compound and run the part under its service load, so stiffness and fatigue life are known before a mould is cut.

02Specialized Materials

The right grade, with its data.

Fifty grades across rubber, cast polyurethane, TPU, TPE and tool steels, laid out as one periodic table. Every lot ships with its TDS, SDS and batch certificate.

03Tooling Services

Moulds and metal parts, held to the drawing.

Cast PU dies, compression and injection moulds, jigs and fixtures, and the machined inserts that bond into your part, measured before they leave the tool room.

04Manufacturing Services

Four routes on one floor.

Hot-cast polyurethane, TPU and TPE injection, rubber compression moulding and 3D printing. We pick the route from your part and your volume, and check every batch at three points.

05Testing Services

Proof on the rig, in one report.

The static lab tests the compound; the dynamic lab loads the finished part the way it will be fitted. Each result names its method and its limit.

On the rig

The same sine load runs on a servo-hydraulic frame, on the finished part, for millions of cycles.
