Manufacturing/Zone 03 — Injection Molding
Production Zone 03Custom Closure Injection Molding From Approved Cap Moulds
Approved in-house cap moulds move directly from the mould workshop to injection lines on the Guangzhou campus. Buyers can audit mould readiness and serial PP/PE closure production in one workflow.
Custom Closure Production On Site
This zone executes custom closure programs after mould approval—not generic off-the-shelf cap trading.
After mould design, machining, and trial approval on the same campus, approved tooling moves to dedicated injection lines for serial production. Process setup, in-process checks, and QC handoff stay under direct engineering control.

From Mould Approval To Serial Production
-
Mould Handoff & Line Setup
Approved moulds are installed and process parameters are set for the target closure program.
-
Serial Injection Run
Custom screw caps, flip-top closures, and application-specific parts run on high-speed multi-cavity lines.
-
In-Process Monitoring
Fill consistency, part quality, and functional fit are checked against the agreed specification.
-
Handoff To QC
Molded closures move to quality control, assembly, or finishing as required by the program.

Frequently Asked Questions
Can FANXUN support mould development and injection production?
Yes. Mould work is handled in the Mold Workshop; serial production runs here after approval—on the same campus.
Is this zone only for standard plastic caps?
No. It supports custom closure programs for lubricant, chemical, food, and personal care packaging—not a generic catalog-only offer.
Do moulds need approval before serial runs?
Yes. Production follows sample trials and approval via the mould workshop or custom mould development.
What should I share for a production quote?
Application context, closure function, drawings if available, resin preference, and program scope. Our team will confirm the next step—mould, injection, or both.
