Ultra-Tight Dimensional Tolerance

Controlled extrusion temperature + CMM full inspection. Tolerance down to ±0.02mm for thin-wall precision parts.

Flexible Order Volume

Support small batch prototyping & mass production. No high minimum order, ideal for startups & tier 1 industrial suppliers.

What Is Zorapid Metal Extrusion ？

Metal extrusion shapes solid metal billets into continuous custom cross-section profiles under high hydraulic pressure.

Zorapid adopts both hot extrusion & cold extrusion technology to match different material & mechanical performance demands:

Hot Extrusion

Hot extrusion forms hard large alloy parts with low force and improved material performance.

  • Process hard alloys (Ti, stainless steel).
  • Low forming pressure.
  • Make large & complex profiles.
  • Less internal stress, fewer cracks.
  • Better mechanical grain structure.

Cold Extrusion

Cold extrusion delivers precise, high-strength metal parts with high material yield and fast production.

  • Ultra tight tolerances & smooth surface.
  • Higher material strength from grain flow.
  • Near 100% material utilization.
  • No heating, lower cost & fast lead time.
  • Minimal secondary machining.

Extrusion materials

Materials are raw materials shaped by extrusion to make various profiles.

Production Capacity & Equipment Strength

Zorapid own a full lineup of modern multi-axis CNC machines, Swiss lathes, grinders and precision inspection gear. All machining and testing are done in-house, no outsourcing.
Our flexible production system supports quick prototypes, small batches and large mass orders alike. Automated equipment guarantees tight tolerances and consistent quality, while scalable capacity keeps lead times short and costs competitive.
From low-volume samples to high-volume serial production, our robust machine fleet and stable output make us your reliable long-term precision machining partner.

Flexible & Scalable Production Capacity

Our workshop layout is designed for flexible manufacturing. We efficiently support low-quantity prototype development, medium batch trial runs and large-volume mass production at competitive lead times.
 
With mature production scheduling systems and skilled machining teams, we can rapidly expand output to accommodate peak order demands. Our stable daily throughput minimizes delivery delays and avoids capacity bottlenecks even for repeated bulk orders.

Core Competitive Edges

  • Full in-house machining & inspection equipment, one-stop manufacturing solution.
  • Scalable capacity to match both prototype and mass production demands.
  • Automated equipment ensures tight tolerance and uniform part quality.
  • Optimized workflow shortens lead time and lowers your production cost.
  • Stable long-term output capacity for recurring industrial orders.

Strict QC Workflow

Strict QC runs through every production step. Professional precision testing tools ensure all parts meet your tolerance requirements before delivery.

Incoming Material Inspection

  • Verify material certificates (COA, material spec).
  • Dimension & hardness spot check.
  • Reject unqualified raw materials with isolation label.

First Article Inspection

  • Produce 1 prototype sample.
  • Full dimensional measurement via CMM.
  • Record FAI report before mass production launch.

In-Process QC

  • Random sampling per production batch.
  • Check surface finish, tolerance, assembly fit.
  • Stop production instantly if defects exceed AQL standard.

Final Inspection

  • 100% appearance screening.
  • Full key dimension testing.
  • Functional test as customer drawing requirement.

Outgoing Quality Control

  • Random batch sampling based on AQL.
  • Packaging, labeling & quantity check.
  • Issue official inspection report before shipment.

Non-Conforming Product Control

  • Separate defective goods into isolation zone.
  • 8D report for mass defect root cause analysis.
  • Rework / scrap approval & traceability record.

FAQ

Can you produce extrusion profiles based on our CAD drawings or samples?

Yes. Our engineering team reviews your STEP/DWG files, conducts extrusion flow simulation, then builds custom molds. We also accept physical sample reverse engineering.

Standard mold lead time: 7–10 working days; rapid prototype service within 72 hours for urgent small batches. Mass production lead time 10–18 days based on order quantity.

No rigid MOQ. We support prototype orders of 1–50 pieces, as well as full container mass production.

Full in-house secondary processing available. We deliver fully finished parts directly, saving your multi-supplier coordination cost.

All shipments come with material certificate, dimension inspection report and hardness test document upon request.
