Precision mold components, made to your drawing.
Punches, ejector pins, guide parts, inserts and CNC-machined components in tungsten carbide, tool steel and HSS. Built for toolmakers and OEMs that need repeatable fit, documented quality and direct engineering support.
Six component families. One standard: the drawing.
Every family is custom-manufactured. Choose the closest route, then send your geometry, material and critical features so we can confirm the process.

Your drawing is the starting point—not a limitation.
We review the part for manufacturability, confirm material and critical tolerances, then plan turning, milling, grinding, EDM or wire EDM around the features that decide fit and service life.
Geometry, tolerance stack-up, material and process feasibility reviewed before quoting.
One-piece trials, small batches and repeat orders supported from the same approved drawing.
Turning, milling, precision grinding, heat treatment coordination and inspection.
A factory built around the tolerance—not the other way round.
A 4,000 m² production floor, imported high-precision machinery and a team that works directly from customer drawings. Capability is visible in the equipment list and in the parts that leave the floor.
Explore capabilitiesInspection is part of production. Not a final box to tick.
Incoming material checks, in-process control and final inspection are planned around the drawing. Critical dimensions are measured with CMM, height gages and 2.5D optical equipment as the part requires.
Made for the places where failure is expensive.
Our components support tooling and equipment across stamping, molding, automotive, electronics, automation, medical and aerospace applications.
