How a part program runs
From first article to repeat orders
One shop from the first part to the production run, so the part you approved is the part you keep getting.
-
First article
A prototype or first part, to check fit before production.
-
Revisions
Changes machined from your updated drawing.
-
Production runs
The approved part, machined the same way each run.
-
Repeat orders
Reordered by part number, with specifications and CAD files kept on file.
Aftermarket parts
Service parts for machines you’ve sold
Spares for the machines your customers run, including parts for older models.
-
Spares for your installed base
Spare parts machined to your drawings, in the quantity you stock.
-
Parts for older models
No drawing for an older model? Send a sample part. We measure it and machine a new one.
Reverse engineering -
When a customer’s machine is down
Our expedited service gets the replacement machined faster, so your customer is back running sooner.

Machined or molded
Why OEMs machine plastic parts
We machine parts from solid plastic sheet and rod. Without a mold, machining suits prototypes, changing designs and production runs that don’t justify tooling.
-
No mold to pay for
Machining starts from stock sheet and rod, so there’s no tooling cost or tooling wait.
-
Design changes are easy
A new revision goes straight from the drawing to the machine, with no mold to modify.
-
Prototype to production
The same process for the first part and the production run, in the plastic your drawing names.
-
Threads and fine features
Threads, undercuts, tight bores and sharp corners machined in, with no draft angles or parting lines.
Plastics
Plastics for OEM parts
The plastics OEMs specify most, and the parts they’re used for.
- Acetal Delrin Low friction, and holds its size. Gears, cams, rollers, structural parts
- UHMW UHMW-PE Resists wear and impact. Wear strips, guides, bearing surfaces
- Nylon Including oil-filled grades Strong and hard-wearing. Bushings, pulleys, load-bearing parts
- PET Polyester Holds close dimensions and takes up little water. Precision bushings and guides
- PTFE Teflon Resists almost every chemical. Seals, liners and gaskets in process equipment
- PEEK Polyetheretherketone Keeps its strength at high temperatures. High-load and high-heat components
- Ultem PEI Stiff and strong when hot. Insulators and housings near heat
- Polycarbonate PC Clear and impact-resistant. Machine guards, enclosures, covers
FAQ
Questions from OEMs
The drawing or CAD model with its revision, the plastic, the quantity (or annual volume for a production part) and when you need it. If the plastic isn’t specified, we’ll suggest one with your quote.
From a single prototype to production runs and repeat orders, each machined to the same drawing.
