Engineering Plastics Machining in Navi Mumbai: overview

PTFE, PEEK, Delrin and Nylon parts machined to drawing. Each polymer gets its own tool geometry, speeds and inspection timing to control heat, burrs and dimensional drift.

Every order is programmed in VISI or Delcam CAM, machined on CNC turning centres and VMC, and inspected in our Mitutoyo quality lab before it is packed and shipped.

Engineering Plastics Machining capability

We run engineering plastics machining on dedicated machines, so prototypes, pilot lots and production runs all follow the same documented process. Common parts include insulators, seals & rings and bushings.

Before quoting, our engineers review your STEP, IGES or PDF drawing for machinability and suggest changes that reduce cost without affecting function.

CNC turning centres (LMW, Jyoti, Ace Micromatics): Shafts, bushings, fittings, turned plastic parts
Vertical machining centre (VMC) (Ace Micromatics, FANUC control): 3-axis milling, bed 800 × 500 × 400 mm
Auto tapping machines (M3 to M32 capacity): High-volume internal threading
Conventional lathe (Uma Enterprises): Turning up to Ø400 × 1200 mm
Band saw (Rajlaxmi): Bar stock cutting and blank preparation

Tolerances & surface finish

Standard capability for this work is ±0.02 to ±0.05 mm depending on polymer. Bores can be held to H7 and bearing seats to h6/g6 fits. Where your drawing calls for tighter limits, we agree the critical characteristics up front and record them on the inspection report.

Surface finish is typically Ra 1.6–3.2 µm as machined, with Ra 0.8 µm achievable on turned sealing and bearing surfaces. Plastics are finished with sharp tools to avoid smearing and burrs.

Plating, anodising, passivation and heat treatment are arranged through qualified partners and re-inspected in-house before packing.

Quality inspection process

Quality is built into every step under our ISO 9001:2015 management system. Raw material is checked against its mill certificate, the first article is fully inspected against the drawing, and in-process checks run at defined intervals.

Every shipment includes a dimensional inspection report, with material test certificates (EN 10204 3.1) on request.
