Manufacturing/Zone 04 — Quality Control
Production Zone 04Quality Control For Custom Plastic Closure Programs
Incoming inspection, in-process checks, and batch release for custom cap mould and closure production on the Guangzhou campus. Therefore, buyers can review how quality is controlled before parts move to testing or shipment.
QC Support For Mould-To-Production Programs
Quality control here supports custom closure projects—not generic trading without process oversight.
After mould approval and injection production, closures pass through defined IQC, IPQC, and finished-goods checks before batch release. In addition, the same campus workflow keeps tooling, production, and quality review connected for buyer audits.

From Production Run To Batch Release
-
Incoming Material Inspection (IQC)
First, resins, components, and inputs are checked against agreed specs before they enter production lines.
-
In-Process Quality Checks (IPQC)
Next, closures are monitored during injection and downstream handling against the buyer’s agreed requirements.
-
Finished Goods Inspection
Then, dimensional, visual, and basic functional checks are completed before a batch is approved for release.
-
Batch Release & Handoff
Finally, approved batches move to the Testing Center or shipment preparation with traceable QC records.

Frequently Asked Questions
What QC checkpoints does FANXUN use for closure programs?
First, programs pass through IQC for incoming materials, IPQC during production, and finished inspection before batch release. In addition, all checks run on the same Guangzhou campus.
Can buyers review QC as part of a factory audit?
Yes. Quality control sits between Injection Molding and the Testing Center. As a result, audit paths can follow mould, production, QC, and testing in sequence.
Is QC separate from functional testing?
Yes. Quality control covers inspection and batch release. In contrast, torque, seal, and leak tests are handled in the Testing Center when required.
What should I share for a QC or production quote?
Share your application, closure specification, inspection requirements if known, and program scope. Then our team will confirm the right production and QC path.
