CGF During production inspection for Gasket Seal Ring

Are you sourcing rubber gasket, silicone seal ring and elastic sealing parts from Chinese factories? CGF provides reliable During Production Inspection (DPI) service for gasket seal rings to control quality during manufacturing.

During Production Inspection is carried out when around 20%–60% of goods are finished. Our inspectors go to the workshop to check semi-finished and finished seal rings before mass production is completed. Early discovery of molding defects, dimensional deviation and material problems helps manufacturers adjust production parameters timely and avoid large batches of defective products.

✅ Raw Material Verification

Check material certificate, hardness, color difference, elasticity and whether raw material meets your specification. Prevent material substitution.

✅ Dimension Measurement

Randomly test inner diameter, outer diameter, section thickness, flatness and cross-section size to control tolerance.

✅ Visual & Appearance Inspection

Inspect surface bubbles, cracks, scratches, burrs, dirt, deformation, incomplete filling and flash caused during molding.

✅ Molding & Cutting Quality

Check cutting edge neatness, joint gap, shape uniformity and no twisting or warping.

✅ On-site Process Audit

Observe injection molding / compression molding working status, production process consistency and operator operation standard.

✅ Sample Recording & Photo Documentation

All non-conforming items will be photographed and recorded. You will receive a full English inspection report after on-site audit.

Avoid shipment delays, customer complaints and product returns by implementing DPI for gasket seal rings. Contact CGF to arrange your in-process factory inspection in China.
