China composite manufacturing directory

Match the composite part to the right process—and the right factory proof.

Compare open-mold, closed-mold, continuous, pressure-cure and thermoplastic routes by geometry, volume and the controls a Chinese supplier should document.

1. Define the part

Geometry, laminate direction, size, surface, tolerance and annual volume set the viable process window.

2. Compare process controls

Material handling, tooling, pressure or vacuum, cure and dimensional control distinguish capability from a process label.

3. Verify factory evidence

Approve the exact product-process relationship through records, trials, inspection and product-level test evidence.
