Cooperation & Fabrication Process

Requirement Review

We review your flat pattern or 3D file, confirming material grade, thickness, and finish requirements before quoting.

Process Planning

Our team maps out the optimal sequence of cutting, bending, and joining, and locks in lead time and pricing upfront.

Programming & Setup

Nesting layouts are optimized for material yield, and bending programs and tooling are configured on the shop floor.

Precision Fabrication

Parts are cut, formed, and welded to spec, with in-process checks at each stage to hold tolerance through to final assembly.

Tolerance & Quality Control

Every sheet metal part we produce goes through a structured quality control process, from incoming material checks to final outgoing inspection.

Our QC workflow follows: Incoming Material Inspection → First Article Inspection (FAI) → In-Process Sampling → Outgoing Quality Control (OQC), keeping cutting and bending dimensions consistent across the full production run.

For dimensional verification, we use CMMs, height gauges, and bend angle testers, issuing full inspection reports on request. Standard tolerances are held within ±0.05–0.1 mm, with tighter tolerances available on critical features.

Custom inspection plans and acceptance criteria can be arranged for projects with specific compliance or certification requirements.

Fabricable Materials

Sheet metal parts can be fabricated from a broad range of metals — from cost-effective carbon steel for structural brackets to corrosion-resistant stainless steel for outdoor or hygienic applications. Browse our standard material options below.

Fabricable Materials

Metals	Characteristics	Common Grades
Aluminum Alloys	Lightweight, excellent formability, and good corrosion resistance.	1060, 3003, 5052, 6061, 6063
Stainless Steel	High corrosion resistance, excellent strength, and good weldability.	201, 304, 316, 430
Carbon Steel	High strength, cost-effective, and widely used for structural parts.	Q235, SPCC, SS400, A36
Brass	Excellent electrical conductivity, good corrosion resistance, and easy to solder.	C11000, C10100
Titanium Alloys	High strength-to-weight ratio, superior corrosion resistance, and lightweight (high machining difficulty).	Ti-6Al-4V (Grade 5), Grade 2 (CP).

Surface Treatment Capability

A fabricated part is only half finished without the right surface treatment. We apply coatings and finishes that protect against corrosion, improve appearance, or prepare parts for further assembly — matched to your application and budget.

Learn More

Basic & Pretreatment Finishes

Cleaning, deburring, and surface preparation to ensure a contamination-free base for subsequent finishing processes.

● Deburring: Removes sharp edges and burrs, improving part safety and appearance.

● Cleaning: Removes cutting fluid, residue, and oxide layer; ensures a contamination-free surface.

Mechanical Finishes

Physical processes that improve surface flatness, smoothness, and texture.

● Sanding / Grinding: Removes machining marks and smooths surfaces.

● Polishing: Improves surface smoothness and gloss.

● Brushing: Creates uniform directional surface textures.

● Sandblasting / Bead Blasting: Removes oxides and creates a matte textured finish.

Protective Finishes

Chemical and electrochemical processes that enhance corrosion resistance and surface protection life.

● Anodizing (Type II / III): Forms a protective oxide layer for improved corrosion and wear resistance.

● Electroplating: Applies a metal coating to improve corrosion resistance, conductivity, and appearance.

Decorative & Marking Finishes

Processes that enhance appearance quality and apply permanent identification.

● Anodizing Coloring: Adds durable and uniform color after anodizing.

● Powder Coating: Forms a durable and weather-resistant protective coating.

Hardening & Functional Treatments

Processes that increase surface hardness, wear resistance, and functional performance.

● PVD / Vacuum Plating: Applies hard decorative coatings for improved wear resistance.

● Salt Bath Nitriding / QPQ: Enhances surface hardness, wear resistance, and corrosion resistance.

FAQ

Do you accept prototype or small-batch orders?

Yes — we regularly produce anything from a single prototype to full production runs, with typical sample lead times of 3–7 working days.
What is your production lead time?

Standard lead time is typically 7–15 working days, depending on material, thickness, and part complexity.
What information do I need to provide for a quotation?

A 2D drawing or 3D CAD file, material and thickness, quantity, and any surface finish requirements.
What are your payment terms?

For new customers, we typically require a deposit before production begins, with the balance due before shipment. Terms can be adjusted for established accounts.
How do you arrange shipping and delivery?

We arrange shipping by sea freight, air freight, or express courier depending on part size, weight, and your timeline, and can ship EXW, FOB, or DDP based on your preference.
How do you handle quality issues?

We investigate the root cause and offer rework, replacement, or credit depending on the issue.
Can you sign a Non-Disclosure Agreement (NDA)?

Yes, we routinely sign NDAs before reviewing customer drawings or discussing project details.
