Custom manufacturing
One partner, from print to production.
Send a drawing or a STEP file. We review manufacturability, recommend the process and material, and deliver inspected parts — prototype quantities through production lots.
- CNC MachiningMilling and turning for metal and engineering-plastic parts, prototypes and fixtures.
- Assembly & IntegrationSub-assemblies, wiring and functional test before shipment.
- Sheet Metal & FabricationCutting, bending and welding for enclosures, brackets and panels.
- Surface FinishingAnodizing, plating, passivation and coatings matched to the environment.
- 3D Printing / AdditiveFast-turn prototypes and complex geometry for design validation.
How we work
From requirement to delivered hardware in four steps.
01
Send requirements
Share a spec sheet, drawing or STEP file — or just the operating conditions.
02
Engineering review
An engineer checks feasibility and recommends a series, process or material.
03
Prototype & test
First articles are built and verified against your requirements.
04
Production & delivery
Inspected parts ship in the quantities and schedule you need.
