Custom CNC Machined Stainless Steel Parts

Supported Materials

We offer CNC machining services for a wide variety of industrial-grade metals and engineering plastics:

Metal Materials:

Aluminum Alloys: 2000 series, 5052, 6061, 7075 — lightweight, corrosion-resistant, ideal for structural parts and enclosures.

Stainless Steels: SUS303, SUS304, SS316, SS316L, 17-4PH — perfect for high-strength and corrosion-resistant applications in medical and marine fields.

Carbon & Alloy Steels: 1214L, 1215, 1045, 4140, SCM440, 40CrMo — engineered for toughness and wear resistance.

Brass & Bronze Alloys: C260, C360, H59–H70, H62, H65, H68, H70, copper — excellent for precision fittings, electronics, and decorative elements.

Titanium: Grade F1 to F5 — known for its high strength-to-weight ratio, ideal for aerospace and biomedical components.

Engineering Plastics:

Acetal (POM), Nylon (PA), PMMA (Acrylic), PVC, Polyurethane, PTFE (Teflon), PEEK, and more — selected for electrical insulation, chemical resistance, and low friction.

Surface Finishing Options

We provide a full spectrum of surface finishing services to improve durability, functionality, and appearance:

Anodizing: Hard and decorative finishes for aluminum components.

Bead Blasting: Creates a uniform matte texture.

Brushing / Polishing: Enhances surface aesthetics and touch feel.

Plating: Zinc, Nickel, Chrome, Titanium — for corrosion and wear resistance.

PVD Coating: Advanced wear-resistant coatings for luxury-grade components.

Powder Coating / Painting: Durable color finish options for visual impact.

Passivation / Electropolishing: Ideal for stainless steel corrosion resistance.

Knurling, Laser Etching & Engraving: Custom logos, textures, and grip patterns.

All finishes are tested for adhesion, thickness, and durability to ensure long-term performance.

Quality is Engineered, Not Assumed

We implement a 3-step quality assurance system, covering:

• Pre-machining verification (tolerance and fixture simulation)
• In-process dimensional control
• Final QC with CMM, roughness testers, and hardness gauges
  Every part comes with an inspection summary upon request.

From Prototype to Production

Need 1 prototype for testing? Or a 500-piece batch for validation?
We support flexible order volumes. With in-house programming and digital job tracking, we reduce turnaround time while maintaining exceptional accuracy.
