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.

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.

Requirement and Drawing Review
01

Requirement & Drawing Review

Confirm drawings, interfaces, critical dimensions, materials, load conditions and acceptance criteria before development begins.

Mold development and tooling preparation
02

Mold Development

Develop and verify production molds, dies, tooling and fixtures according to the approved drawings, dimensions, materials and forming requirements.
