QUALITY CONTROL THROUGH PRODUCTION

Quality Checks That Protect Your Production and Shipment

We check the points that create the biggest risk—material condition, first-part dimensions, part consistency during molding, and final packing—so issues are found before they become scrap, delays, or shipment problems.

01

Avoid Material-Related Defects

Material inspection and moisture testing help prevent unsuitable resin condition from causing molding defects.

02

Prevent Batch Problems Early

First article and dimensional checks compare initial parts with the drawing before larger quantities are made.

03

Keep Parts Consistent During Production

Regular sampling and visual checks help identify part variation while production is running.

04

Reduce Shipment Risk

Final part, functional, and packing checks help stop identified issues from reaching shipment.

FIRST PARTS AND PRODUCTION SAMPLES

Prevent Quality Problems Before Mass Production Starts

First parts and production samples are checked against the requirements that affect assembly, product appearance, and function—before a small issue becomes a larger production problem.

01

Avoid Assembly Delays

Dimensions and mating features are checked against the drawing before mass production starts.

02

Protect Product Appearance

Visible surfaces are checked for defects, color variation, and molding marks that could affect customer acceptance.

03

Confirm Critical Features Work

When function-related features are required, they are checked before more parts are produced.

BEFORE SHIPMENT

Final Inspection and Packing Before Delivery

Before parts leave the factory, final inspection and packing are reviewed together to help prevent avoidable problems at your receiving team, assembly line, or customer.

01

Catch Issues Before Parts Leave the Factory

Finished parts are checked against the agreed inspection points before they are packed for shipment.

02

Reduce the Risk of Transit Damage

The packing method and protection are reviewed to reduce movement, contact, and surface damage during transit.

03

Help Your Next Step Stay on Schedule

Finding issues before shipment helps avoid unexpected problems when parts arrive for receiving or assembly.
