Four failures we see on incoming parts.
Plastic springs back once the tool leaves the cut. Thin ribs and long unsupported walls move 0.05 mm or more, and the mating part no longer fits. A roughing pass, a stress relief pause and a light finishing pass hold the wall where the drawing says it should be.
POM and ABS melt at the tool tip if the feed is wrong. You get a burr that will not break off, a cloudy surface and a dimension that keeps shrinking as the part cools. Sharp carbide, high spindle speed and air blast keep the chip clear and the edge clean.
Every day spent waiting on a price is a day the project slips. We return a quotation and free DFM analysis within 12 hours, and production can start within 24 hours of approval. That keeps a prototype round inside the same week.
The prototype fits, the production run does not. Tool wear, a new lot of resin and a warm shop all move the number. We inspect 100% of parts before shipment and monitor dimensions in process so part 500 sits where part 1 did.
Same spindles, same metrology, different cutting data.
A plastic part is not a metal part with a softer material. PEEK and PA absorb moisture and grow before the cut starts, so we dry or anneal the blank first when the drawing is tight. POM cuts clean at high speed but burns if the tool dwells. ABS and PC want a sharp edge and a fast exit or they tear.
We keep a material-specific cutting library for 6061, POM, PC, PEEK, PMMA, PA, PP, HDPE and carbon fibre. The CAM program pulls the right step-over, depth of cut and coolant setting from it, so a new job does not start from a guess.
Sixteen simultaneous 5-axis centers cut angled holes and contoured faces in one setup, which matters when a plastic housing has features on five sides and every re-clamp risks a scratch. Twelve four-axis mills and sixteen mill-turn centers handle round parts with cross-drilled holes. Twenty-seven three-axis machines take the simple, high-volume work.
The largest travel is 4,000 × 400 × 150 mm for long panels and rails. Medium and compact travels cover most enclosures, manifolds, insulators and wear pads. A Ø400 mm rotary table lets us cut a curved slot in one pass instead of stepping around it.
Pick the resin before you pick the tolerance.
| Plastic | Good for | Watch out for |
|---|---|---|
| POM (Delrin) | Gears, bushings, sliding parts | Burns if the tool dwells; needs sharp carbide |
| PEEK | High-temperature and chemical exposure | Costs more; anneal before tight cuts |
| PC | Clear covers, impact-resistant housings | Stress-cracks near a sharp internal corner |
| ABS | Enclosures, brackets, prototypes | Tears at low speed; low solvent resistance |
| PA (Nylon) | Wear pads, rollers, clips | Absorbs moisture and grows after machining |
| PMMA (Acrylic) | Optical windows, light guides | Chips easily; polish after cutting |
| HDPE / PP | Chemical tanks, low-cost covers | Soft and gummy; hard to hold a tight tolerance |
| Carbon fibre | Stiff, light structural panels | Abrasive dust; tool wear is fast |
Machining is the core. These are the steps that come with it.
Angled holes, contoured faces and undercuts in one setup. Best for housings with features on several sides.
Flat plates and pockets on the mill, round bushings and rollers on the lathe. The workhorse route for most plastic parts.
A rotary axis cuts slots and flats around a cylinder without a second fixture. Good for manifolds and fittings.
One part, one setup, shipped in days. Use it to test fit before you commit to a mold or a run.
Bead blasting, tumbling, brushing and polishing. Laser marking is available down to 1.5 mm character height.
When the geometry has internal channels a cutter cannot reach, printing fills the gap. We run both routes side by side.

Fifteen years cutting metal and plastic in Dongguan. Three wholly-owned plants, 7,600 m² under one quality system.
Micron-level work on critical features. We measure on the machine and again at final inspection, so a number on a report matches a number on a part.
A quotation and DFM notes land within 12 hours of the upload. If the design has a problem, we say so in the same reply instead of waiting for the first article.
Sixteen 5-axis centers, twelve 4-axis mills, sixteen mill-turn centers and twenty-seven 3-axis machines. Capacity is in-house, not brokered out.
Long plastic panels and rails stay on one machine and one setup. Medium and compact travels cover smaller enclosures and fittings without a special fixture.
No minimum order quantity. A single prototype and a 10,000-part run go through the same inspection and the same paperwork.
Bumper brackets, sensor housings and clip-in trim. The industry wants a Class A surface, no sink marks and a fit that survives a heat cycle.
PEEK and PC instrument housings, manifolds and fluid path parts. Clean edges, no trapped chips and a documented inspection record matter more than speed.
End-effector jaws, gear housings and cable guides in POM and PA. Light weight plus repeatable geometry, so a gripper hits the same point every cycle.
Insulators, test fixtures and connector bodies in PC and PMMA. Dimensional stability across a reflow profile and a clean optical face are the two requirements.
Machining wins when the quantity is low, the geometry changes often, or the part is large and flat. A mold has to be cut and paid for before the first good part appears, and any design change means a new tool.
For a bracket, a test fixture or a 20-piece pilot run, machining gets a finished part into your hands in days. Above roughly 10,000 identical parts with no changes, molding usually costs less per piece. We run both routes, so we can tell you which side of that line your part sits on.
ABS, PC, PMMA, POM, PA, PEEK, PP, HDPE and carbon fibre-reinforced stock. POM and PC are the most common requests. PEEK and carbon fibre are available but cost more and cut slower.
If your drawing names a grade we do not stock, send the data sheet. We will say whether we can source it and what the lead time looks like before you commit.
We work to ±0.005 mm (±0.0002 in) on critical features. Plastic moves with temperature and moisture, so the number applies to the shop environment, not to a part sitting in a humid warehouse for a month.
For a long unsupported wall or a thin rib, we will tell you at the DFM stage which dimensions are realistic and which will need a design tweak.
Almost always for anything beyond a simple block. Soft jaws grip a finished face without marking it. A vacuum plate holds a thin panel flat while the top is cut. Custom fixtures are made in-house, so they do not add a week to the schedule.
If the part can be held in a standard vise with soft jaws, we skip the custom fixture and keep the cost down.
Sharp carbide tooling, the right feed per tooth, and a finishing pass with a light depth of cut. Air blast keeps the chip out of the cut so it does not rub the wall and leave a mark.
For parts that need a clean edge, we add a deburring step by hand or a tumble cycle. Tell us on the drawing which edges are cosmetic and which can be broken.
Yes. There is no minimum order quantity. One part or a 10,000-piece run goes through the same inspection and the same documentation.
A prototype often ships in the same 3–5 day window as a small run, because the setup is the same for both.
A quotation and free DFM analysis come back within 12 hours of the upload. The DFM notes flag thin walls, sharp internal corners, deep pockets that need a long tool, and any tolerance that will be hard to hold.
Production can start within 24 hours of approval if the material is in stock.
Uploads are kept secure and confidential. An NDA is available on request, and we will sign yours if you have a standard form.
Only the engineers who program and run your job see the files.
Upload your file and we will come back within 12 hours with a price, a lead time and notes on anything that will be hard to machine.
