We machine ABS, POM, PEEK, PA, PC, PP, PMMA and HDPE from one prototype to 10,000+ parts. Tolerances hold at ±0.005 mm, and every lot ships with inspection records you can file.
These are the failures we get called in to fix.
ABS and PP cut hot. A tool path run at metal speeds leaves gummy edges, stringy chips and a finish that no bead blasting will hide. You end up hand-deburring parts that were supposed to come off the machine ready.
POM and PA absorb moisture and move after machining. A bore that gauges on size at 4 pm can be 0.02 mm off the next morning. If the drawing calls for a press fit, that drift becomes a scrap batch.
Thin ribs and 1 mm walls bow under clamping force. The cutter pushes instead of shearing, so the finished face reads wavy on a height gauge. Soft jaws and light passes fix it, but only if the shop plans for it before the first cut.
Same feeds, same cutters, same coolant. PEEK and PEI then come back with subsurface cracks or a chalky surface. Re-machining a cracked part rarely saves it, and the second run costs you the schedule you promised.
Material first, then geometry, then tolerance.
Every polymer cuts differently. PEEK and PEI are abrasive and need sharp carbide with high rake angles. POM machines clean and holds a crisp edge. HDPE and PP want high positive rake and generous chip clearance so the chip leaves before it re-welds to the wall.
We keep a cutting library per resin and adjust from the first article. You get a part that measures right and looks right, not one that needs a second operation to hide the first.
Plastic parts are often thin, tall or open on one side. Clamping them the way you would clamp aluminum introduces stress that shows up as a bowed face or an out-of-round bore. We fixture on soft jaws, vacuum plates or sacrificial tabs, and we take light finishing passes to release the stress.
With 16 simultaneous 5-axis centers we reach undercuts and angled faces in one setup. Fewer setups means less re-clamping, and less re-clamping means the last dimension is as good as the first.
A quick read on common trade-offs.
| Resin | Good for | Watch out for |
|---|---|---|
| ABS | Housings, covers, brackets | Low stiffness, heat softens it |
| POM (acetal) | Gears, bushings, sliding parts | Hard to bond, moves with moisture |
| PEEK | High heat, chemical contact | Abrasive, tool wear, high cost |
| PA (nylon) | Wear strips, structural clips | Absorbs moisture, dimension shift |
| PC | Impact covers, guards | Stress cracks near sharp corners |
| PMMA | Optical windows, light guides | Brittle, chips easily when tapped |
Machining is the core. These are the steps that come with it.
Milling and turning on 127 machines, up to 4,000 mm travel for long parts. Simultaneous 5-axis handles compound angles and undercuts in one setup.
Mill-turn centers cut round and prismatic features without re-fixturing. Good for bushings, rollers, manifolds and threaded bodies.
Machined prototypes in the production resin, so the material behaves like the final part. No substitute resin, no surprise on the production run.
Bead blasting, tumbling, brushing and polishing. Laser marking to a minimum character height of 1.5 mm when parts need traceability.
When a plastic housing needs a metal frame or bracket, we build both and check the assembly fit before shipping.
Insert installation, bonding and dimensional reports. 100% inspection before shipment, with raw material and in-process checks logged.
Pick the envelope that fits your part.
| Machine type | Envelope | Typical plastic work |
|---|---|---|
| 5-axis centers (16) | Ø400 mm rotary table | Angled ports, impellers, joints |
| Mill-turn (16) | Up to 4,000 mm length | Rollers, bushings, threaded bodies |
| 3-axis mills (27) | 750 × 1,150 × 550 mm | Plates, covers, manifolds |
| 4-axis mills (12) | 600 × 600 × 600 mm | Prismatic parts with side holes |
| Large travel | 4,000 × 400 × 150 mm | Long extrusions and rails |
| Compact cells | 500 × 500 × 450 mm | Small precision components |
Bores, pockets and faces verified against the drawing. Imperial drawings read ±0.0002 in on the report.
Fine finishes where sealing or sliding contact matters. As-machined Ra 1.6–3.2 μm is fine for most covers.

Once the first article is approved, the run begins. Parts ship in 3–5 days.
Founded in 2011. Three wholly-owned plants and 7,600 m² of floor space in Dongguan, plus a Singapore site.
One prototype or 10,000+ parts, same process and same inspection standard.
Robot joint housings and gripper jaws in POM and PA. The requirement is tight bore alignment across an angled face.
Insulating spacers, light guides and enclosures in PC, PMMA and ABS. The requirement is flatness and clean optical edges.
Housings and fixtures in PEEK and PEI. The requirement is repeatability lot to lot and a paper trail.
Wear pads, guides and manifold blocks in PA, HDPE and POM. The requirement is dimensional stability under load.
ABS, PC, PMMA, POM, PA, PEEK, PP and HDPE, plus carbon fibre sheet. If you need a resin that is not on that list, send the datasheet and we will tell you whether it cuts cleanly or needs a different process.
We fixture on soft jaws or a vacuum plate and take light finishing passes rather than one heavy cut. Clamping pressure is set so the wall is supported, not squeezed. The bore and the outer face are checked on a CMM before the run continues.
Both absorb moisture, so they can move after machining. We rough machine, let the part rest, then finish to the drawing. For tight fits, tell us the service environment so we can bias the dimension rather than hold it dead-on at the machine.
Up to 4,000 mm on the long travel machines, with a 4,000 × 400 × 150 mm envelope. Most plastic work fits the 750 × 1,150 × 550 mm or 600 × 600 × 600 mm range.
Yes. We machine the prototype in the production resin on the same class of machine, so the material behaviour carries over. There is no minimum order quantity, so a single prototype and a 10,000-part run go through the same inspection standard.
As-machined Ra 1.6–3.2 μm, high finish Ra 0.8–1.6 μm, and fine finish Ra 0.2–0.8 μm. Bead blasting, tumbling, brushing and polishing are done in house, and laser marking is available at a minimum character height of 1.5 mm.
