Integrated Manufacturing
One connected system.
From requirement to release.
Manufacturing quality is created long before final inspection.
Changxin aligns drawing review, process planning, material control, first-piece approval, in-process inspection and final release around the same approved requirements, supporting customized trial orders and repeat volume production.
01DefinedDefine technical requirements and key part features early.
02ControlledStrictly control manufacturing processes, tools, and methods.
03VerifiedValidate dimensions, functions, and overall performance.
04ImprovedDrive continuous improvement through feedback and corrective actions.
Core Capabilities
Capability at every
critical handoff.
Internal production capability covers the key handoffs from product design and tooling through forming, machining, welding, finishing, assembly and final inspection.
Material & Forming

Process Discipline
Technology supports the process.
Discipline protects the result.
Equipment creates capability, but stable output depends on how requirements, tooling, operators, inspection and maintenance work together. We focus on the controls surrounding each operation, not the machine name alone.
Production Flow
A standardized six-step path
from review to improvement.
The manufacturing flow is organized around decision gates. Each gate confirms that the next stage has the information and evidence it needs.
01
Requirement & Drawing Review
Confirm drawings, interfaces, critical dimensions, materials, load conditions and acceptance criteria before development begins.
02
Mold Development
Develop and verify production molds, dies, tooling and fixtures according to the approved drawings, dimensions, materials and forming requirements.
03
Precision Machining & Stamping
Complete precision machining and stamping operations to achieve the approved geometry, dimensions and edge quality before downstream joining.
04
Welding
Join formed and machined components using controlled welding parameters, fixtures and visual checks for consistent assemblies.
05
Salt Spray Testing
Verify the selected surface treatment through salt-spray testing according to the confirmed project requirement and test method.
06
Assembly & Quality Inspection
Complete assembly and final inspection, confirming fit, dimensions, appearance and required functional checks before release.
