CGF During Production Inspection(DPI) 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.
Complete Inspection Items for Gasket Seal Ring
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.

Industries We Cover
Where We Operate
Zhejiang, Jiangsu, Shanghai, Guangdong (Dongguan / Shenzhen / Foshan / Shunde), Qingdao, Sichuan, Chongqing and across China.
Inspection Standards We Work To
| Standard | What it covers |
|---|---|
| AQL (Acceptance Quality Limit) | Defines the maximum number of defective units acceptable in a random sample — the basis of our sampling plans. |
| ANSI/ASQ Z1.4 | U.S. standard for sampling by attributes (single, double and multiple sampling). |
| ISO 2859-1 | International general standard for sampling by attributes, equivalent to ANSI/ASQ Z1.4. |
| ISO 9001 | Quality management system baseline referenced in our factory audits. |
| IEC / EN / ASTM | Product-specific safety & performance references applied per your specification. |
Every CGF assignment includes
- An independent, on-site inspector working for you — never the factory
- Internationally recognised AQL sampling (ANSI/ASQ Z1.4 · ISO 2859-1)
- On-site photos embedded in every report
- A detailed, bilingual English inspection report within 24 hours of the visit
