RENJIE® — Your Global PEEK Machining Partner

RENJIE® is an innovative company specialising in high-performance engineering plastics and PEEK machining. We provide global customers with a one-stop service that runs from PEEK granules to PEEK sheet and rod, and on to precision machining of finished parts.

Years of accumulated process know-how, combined with advanced production equipment, let us respond quickly to customer requirements and deliver customised PEEK machined parts — with material, geometry and inspection handled under one roof rather than across three suppliers.

Our Core Advantages

Full-industry-chain service

From raw material procurement and material modification, through sheet and rod manufacturing, to CNC precision machining — genuinely one-stop PEEK machining. One purchase order, one specification conversation, one point of accountability for dimensional and performance consistency.

Strong customisation capability

We select material flexibly against customer drawings, dimensions and performance requirements — pure PEEK, glass-fibre reinforced PEEK and carbon-fibre reinforced PEEK — and combine it with CNC turning, milling, drilling and related processes to meet diverse application needs.

Strict quality control

High-standard inspection is applied at every stage: raw material pre-treatment, processing and finished-product testing. Every part is dimensionally accurate with stable performance, and the inspection record follows the part.

Rapid delivery

Mature production processes and efficient project management shorten the design-to-delivery cycle, so customers can move on market opportunities instead of waiting on tooling.

PEEK Machining Customisation Process

Step 1 — Requirements communication. Customers provide drawings, specifications, performance characteristics and application scenarios for the PEEK machined parts.

Step 2 — Solution design. Engineers develop the machining solution from those requirements, covering material selection, process routes and mould design if required.

Step 3 — Raw material preparation. Standard-compliant PEEK sheet or bar is selected and pre-treated, for example by drying.

Step 4 — Machining and manufacturing. Precision manufacturing is carried out on CNC machining centres with strict control over cutting parameters.

Step 5 — Quality inspection. Dimensions, appearance and performance are inspected using precision measuring instruments.

Step 6 — Post-processing. Deburring, polishing and heat treatment improve product precision and appearance.

Step 7 — Packaging and delivery. Packaging follows customer requirements, and quality certification documents are provided to ensure safe, timely delivery.

Application Areas

PEEK machined products are widely used in aerospace, medical equipment, electronic semiconductors and the automotive industry, among other fields.

With high temperature resistance, chemical corrosion resistance, high strength and light weight, PEEK machined parts perform exceptionally well even under the most demanding working conditions — which is why the material is specified where metal has reached its thermal or chemical limit.

Why Buyers Choose RENJIE®

• One supplier, full chain — granules, modified compounds, sheet, rod and finished machined parts.
• Material range — unfilled, glass-fibre reinforced and carbon-fibre reinforced PEEK.

Frequently Asked Questions

What PEEK materials can you machine? Pure PEEK, glass-fibre reinforced PEEK and carbon-fibre reinforced PEEK, selected against the drawing and the performance requirement.

Do you supply the raw material as well as the machined part? Yes. We supply PEEK granules, sheet and rod, and machine finished parts from them — a single chain from material to component.

What processes are available? CNC turning, milling and drilling, plus deburring, polishing and heat treatment for post-processing.

How is quality controlled? High-standard inspection at every stage — raw material pre-treatment, processing and finished-product testing — using precision measuring instruments.

Which industries do you serve? Aerospace, medical equipment, electronic semiconductors and automotive, among others.

What information do you need to quote? Drawings (2D/3D), dimensions, performance characteristics, application scenario, quantity and any inspection or surface-finish requirements.
