Products

All products are custom-molded to your drawing (OEM). The parts below show the types we build — your version is made to your specification, in your choice of POM, Nylon, PC or ABS.

Rows of white POM plastic gears molded in our factory — spur, helical, worm and special-shaped gears
Off our own machines: white POM gears from production — spur, helical, worm, sector and special-shaped parts.

The products shown on this page are examples of the types we make. Many custom products are never published — customer drawings and custom projects are kept confidential and are not shown online. If you do not see your part here, send us your drawing or sample: we make it to your drawing.

The range also covers micro transmissions: micro gearboxes from Ø 3.4 mm and gears down to module M0.1 — with transmission design support (meshing analysis, tooth profile modification, mold-flow analysis) available before tooling starts. High-precision custom work is a core strength: precision molds and high-precision gears are designed and made to your drawing, not adapted from stock parts.
