Custom OEM Sourcing Orders

Professional B2B Wholesale Overview

ATI ENTERPRISE CO PTY LTD coordinates technical blueprint auditing, tooling manufacture, process control, and logistics delivery of custom OEM (Original Equipment Manufacturer) metal, plastic, and composite components. We work with certified manufacturing facilities in Jiangsu, Zhejiang, and Guangdong to deliver compliant wholesale shipments.

1. Custom B2B OEM Sourcing Scope

Our OEM division manages custom manufacturing projects, ensuring raw materials and tolerances meet client blueprints. We coordinate contract manufacturing for:

• Sheet Metal & Machined Components: High-precision CNC milled parts, stamped metal bracket assemblies, laser-cut components, and custom structural frames.
• Plastic Injection Molding: Design and manufacturing of high-durability plastic enclosures, structural brackets, and composite material parts.
• Aluminum Extrusions: Custom extruded profiles, heat sinks, frame rails, and specialized brackets finished in anodized coatings.
• Turnkey Assembly Sourcing: Full coordination of sub-component procurement, hardware mounting, product packaging, and private label box printing.

2. Technical Quality Controls & Tolerance Checks

Custom OEM parts require strict compliance with design tolerances to ensure proper assembly. Our inspectors perform comprehensive checks on each production batch:

OEM Component	Primary Quality Parameter	QA Inspection Audit Tool	Material Certification Requirement
Precision Machined Parts	Dimensional tolerance limits (+/- 0.02mm), surface roughness	Coordinate Measuring Machine (CMM) audit, micrometer check	Raw Material Mill Certificate & Spectroscopic analysis
Plastic Molded Parts	Shrinkage rates, stress cracks, weight accuracy	Go/No-Go plug gauge checks, high-heat stress testing	RoHS Compliant Polymer Raw Material proof
Aluminum Extrusions	Profile angles, anodized coating depth, deflection limits	Digital coating thickness gauge check, tensile deflection audit	Grade 6063/6061 T5 Alloy Material Proof
Assembly Components	Thread thread alignment, function checks, packaging durability	Standard assembly fitment audit, Carton Drop Test (ISTA 1A)	Complete Safety Declaration records

3. Tooling (Mold) Ownership and Intellectual Property Protection

Custom manufacturing requires significant tooling and intellectual property security. We establish clear legal contracts to protect our clients:

• Tooling Ownership Contracts: Clients retain full ownership of all custom injection molds and stamping dies. Molds are tagged with unique registration marks and stored securely at audited facilities.
• Intellectual Property Security: We enforce strict Non-Disclosure Agreements (NDAs) with all manufacturing partners, preventing design leaks or third-party distribution of custom parts.
• First Article Inspection (FAI): Production tooling runs only start after the client inspects and signs off on the official FAI sample, accompanied by a complete dimensional report.
