A ABS cover solves problems metal cannot: insulation, dry running bearings and chemical resistance without corrosion. ABS cover for electronics work is produced here with machining of engineering plastics with sharp tooling and heat control. The sections below describe what is held on the drawing, how the part is made and what arrives with the shipment.
The parts that matter most are the interfaces: bores, sealing faces, threads and mounting patterns. Those are held to ±0.05 mm, verified against the drawing, and recorded before anything is packed.

Manufacturing process
The operation sequence is decided before the first chip is cut: roughing to leave even stock, semi-finishing, then machining of engineering plastics with sharp tooling and heat control as the final operation. That order is what keeps ±0.05 mm stable as the batch runs and the machine warms up.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Insulating bushes and washers.
- Food contact wear parts.
- Laboratory fluid manifolds.
- Light duty gears and rollers.
- Electrical enclosures.
Quality control and documentation
Every batch is measured against the drawing with calibrated equipment, and results are recorded against the part number rather than kept on a scrap of paper.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Quotations are returned within one working day of a complete drawing package. Lead time is quoted from drawing approval, not from the date of enquiry.
Frequently asked questions
Do plastics hold tight tolerances?
They hold ±0.05 mm reliably, but dimensions move with temperature and with moisture in nylons, so parts are measured at 20 °C after conditioning.
Why machine plastic instead of moulding it?
Below a few hundred pieces, machining avoids tooling cost entirely and allows design changes between batches without altering a tool.
Can you supply material and inspection certificates?
Yes. Material certificates to EN 10204 3.1, full dimensional reports, first article inspection reports and, where required, PPAP or AS9102 documentation are issued with the shipment.
To discuss cover requirements, send the model and the drawing with the quantities required. Feedback on manufacturability is given free of charge before any order is placed.
