Processing Technology

Core Capabilities

Integrated Manufacturing Processes

From raw material to finished product — complete in-house processing capabilities

01

CNC Precision Machining

5-axis and 3-axis CNC milling, CNC turning (Swiss-type & conventional), wire EDM, and grinding. Tolerances down to ±0.005mm for complex geometries in metals and alloys. Our 80+ CNC machines run 24/7 for maximum production efficiency.

02

Metal Stamping & Forming

Progressive die stamping (25T–400T), deep drawing, blanking, piercing, bending, and coining. In-house die design and manufacturing. Capable of processing 50M+ pieces monthly with consistent quality.

03

Cold Heading & Thread Rolling

Multi-station cold heading for fasteners and custom-shaped parts. Thread rolling for superior thread strength and finish. High-speed production with excellent material utilization.

Surface Treatment

Precision Finishing & Plating

Comprehensive surface treatment options for corrosion resistance, aesthetics, and wear protection

★

Zinc Plating

Clear / Blue / Yellow / Black zinc with trivalent chromium passivation. RoHS compliant. 8–25μm thickness.

★

Nickel & Chrome Plating

Bright nickel, electroless nickel, decorative chrome, and hard chrome for wear resistance.

★

Anodizing

Clear, colored, and hard anodizing for aluminum parts. MIL-A-8625 and ISO standards.

★

Powder Coating & E-Coating

Epoxy, polyester, and hybrid powder coating. Cathodic e-coating for superior corrosion protection.

★

Polishing & Brushing

Mechanical polishing, electropolishing, and wire brushing for decorative and functional finishes.

★

Passivation

Nitric acid and citric acid passivation for stainless steel. ASTM A967 and ASTM A380 standards.

★

Heat Treatment

Quenching & tempering, carburizing, nitriding, carbonitriding, induction hardening, and annealing.

★

Laser Marking

Permanent laser engraving for logos, batch numbers, serial numbers, and compliance markings.

Quality Control

3-Step Quality Inspection System

IQC

Incoming Quality Control

Raw material inspection with spectrometer analysis, hardness testing, and dimensional verification. Every batch of material is verified before entering production.

IPQC

In-Process Quality Control

Real-time SPC (Statistical Process Control) monitoring during production. First-piece inspection, in-process sampling, and machine capability studies (Cpk ≥ 1.33).

OQC

Outgoing Quality Control

Final inspection per AQL sampling standards (AQL 1.0 / 0.65). Full dimensional reports, surface finish verification, and packaging inspection before shipment.
