Plastic Rapid CNC Machining Service

InstaMFG’s Plastic Rapid CNC Machining Service transforms your CAD models into precision plastic parts in as little as 24 hours, with flexible lead‑time tiers to match your budget and schedule. We machine a wide spectrum of engineering plastics—from commodity grades like ABS and PC to high‑performance polymers such as PEEK and PTFE. Our Design Guide helps you optimize wall thickness, draft angles, and toolpaths for faster cycles and less waste. Inside our state‑of‑the‑art Shenzhen facility, 5‑axis mills and EDM stations churn out mold‑ready inserts with ±0.005 in (0.13 mm) tolerances Quality is assured via ISO 9001 processes, Statistical Process Control, and 3D optical inspection at every phase . Finally, choose from matte, satin, high‑gloss, or textured finishes per SPI and VDI standards to get the exact look and feel you need.

Commonly requested materials:

• ABS – cost‑effective, easy to paint, ideal for consumer enclosures
• Polycarbonate (PC) – impact‑resistant and optically clear for lenses and housings
• Nylon (PA6/PA66) – wear‑resistant for gears and mechanical components
• Acetal (Delrin, POM) – low‑friction and dimensionally stable for precision fittings
• PEEK – high‑temperature performance for aerospace and medical parts
• PTFE – chemical‑resistant for seals and insulating applications
• UHMW‑PE – ultra‑low friction for liners and wear plates
• TPU – flexible, abrasion‑resistant for grips and seals
• PMMA (Acrylic) – excellent clarity for light guides
• PEI (Ultem) – flame‑retardant, UL 94 V‑0 rated for electrical component

InTurnaround in as fast as 24 hours with tiered lead‑time options—expedite, standard, or economy—so you pay only for the speed you need INSTAMFG​Manufacturing on Demand. Our fleet of high‑speed CNC routers and mills handles runs from a single prototype to hundreds of parts, all programmed via digital workflows that link directly to your CAD files for zero‑error setup. Rapid quoting, online order tracking, and instant DFM feedback keep you in control from upload to delivery.

CNC Machining Design Guide

Master the essentials of wall thickness, draft angles, and fillet radii to minimize tool wear and cycle times. Learn how to plan clamping strategies, toolpath ordering, and rest machining for complex geometries—all tailored for plastics

Inside Our High‑Speed CNC Facility

Explore InstaMFG’s 50,000 sq ft Shenzhen workshop, equipped with 5‑axis mills, high‑feed routers, and EDM stations that produce mold inserts and final parts in under 24 hours . Our digital shop floor network provides real‑time status updates, ensuring transparency at every step.

Quality Assurance & Inspection

We maintain ISO 9001 certification and employ a robust Quality Management System (QMS) to track and document each order from raw stock to final shipment . Our QA team uses Statistical Process Control (SPC) alongside optical 3D scanning at key stages—pre‑machining validation, mid‑run audits, and final inspection—to catch deviations and guarantee every part meets your specifications

Surface Finish & Tolerances

Choose finishes per SPI and VDI classifications: matte, satin, or high‑gloss. We also offer engineered textures and laser marking for logos or part numbers . Standard tolerances are ±0.005 in (0.13 mm), with tighter precision down to ±0.002 in (0.05 mm) available upon request.
