Industry
Robots live on precise, lightweight moving parts that must fit the first time. We make custom components for robot joints, end effectors, chassis, and controls — from a single prototype to full production runs.
CNC machining, 3D printing, injection molding, and sheet metal — four proven processes from one factory-direct supplier, with in-house engineering and DFM support.
How we help
Robot parts are assemblies of many parts. A hundredth of a millimetre matters at every joint. We hold tight tolerances and repeat them across every batch.
Every gram on a robot arm costs payload and battery life. We help you pick thin-wall aluminum, engineering plastics, and optimized shapes that cut weight without losing strength.
Our engineers review your files before production. You get practical feedback on wall thickness, draft angles, bearing fits, and tolerances — at no extra cost.
CNC machining, 3D printing, injection molding, and sheet metal under one roof. Fewer vendors to manage, fewer gaps between prototype and production.
Most quotes come back within 24 business hours. Prototypes in days — so your next engineering iteration starts this week, not next month.
All files and ideas are treated as confidential. We sign NDAs whenever you need one — before you send a single drawing.
Solutions
Not sure which process fits your part? Start here. Each card shows what the process does best and the robot components we make with it.
Parts cut from solid metal or plastic. Best when a joint, shaft, or bearing seat must stay accurate under load — batch after batch. No tooling needed for prototypes.
Typical parts:
Parts built layer by layer from your CAD file. The fastest way to test a joint design, check an assembly, or print a gripper — no molds, no cutting tools.
Typical uses:
Plastic parts made in volume. Melted resin is injected into a steel mold, cooled, and ejected — every part identical, at a low unit cost.
Typical parts:
Flat metal cut, bent, and welded into parts. The go-to choice for chassis, frames, and control cabinets that must be strong, thin, and light.

Solution 01
CNC machining cuts a part out of a solid block of metal or plastic. A computer-controlled tool removes everything that is not the part. What stays is strong, precise, and repeatable.
This is our first choice for the moving and load-bearing parts of a robot. Joints, shafts, and bearing seats must stay accurate under load — that is exactly what machining does best.

No mold is needed. You send a drawing, we cut metal, and you have a real part in your hand — usually within days. That makes CNC the fastest path from CAD to a working robot joint.
Solution 02
Injection molding makes plastic parts in volume. Plastic pellets are melted and injected into a steel mold. The part cools, hardens, and pops out — identical every time.
Once the mold exists, each part costs little and comes out fast. If your robot design is settled and the order is in the thousands, this is the most economical way to make covers, housings, and grips.

We make the molds in-house and use hot runner and valve gate systems for clean parts. Nylon is a favourite for gripper fingers — it is light, tough, and slides against itself without grease. 2K and insert molding are available when a part needs two colors or metal threads.
Solution 03
Sheet metal fabrication cuts, bends, and welds flat metal into a finished part. No molds are needed, so it works well for prototypes and for parts that change often.
It is the natural choice for the structure of a robot — the chassis, frames, and cabinets that hold everything else in place.

Aluminum keeps the frame light and easy to move. Steel adds stiffness where loads are high. We weld, deburr, and finish every part so it is safe to handle and ready to assemble.
Solution 04
3D printing builds a part layer by layer, straight from your CAD file. There are no molds and no cutting tools — just the file and the printer.
Robot teams iterate faster than anyone. Print today, test the joint tonight, change the design tomorrow. That is why 3D printing is the default first step for almost every robot project.

Nylon (SLS) prints gripper fingers that flex and survive thousands of grips. Metal printing makes load-bearing joint prototypes from real stainless or tool steel. Test first, then commit to production tooling.
