High-Precision Cold Heading Main Die
For main forming in multi-station cold headers; cavity profile customized to wire diameter and fastener spec.
Screw dies, ejector pins, shaped punches, custom nuts, used screw machines and fastener accessories — 26 years of Dongguan manufacturing, factory-direct for automotive, machinery, electronics and construction buyers.

Wanying Hardware is the export brand of Dongguan Wanying Trading Co., Ltd., rooted in the Dalang fastener cluster for 26 years. Sharing a manufacturing base with Jinghong Mold but focused on a different market, Wanying specializes in screw-forming tooling — from screw dies and ejector pins to shaped punches, custom nuts and used screw machines — giving global fastener buyers one reliable sourcing partner.
We are more than a trading company — we are a manufacturing window. Drawings or samples go straight to the die shop and cold-heading lines, where engineers evaluate material, tolerance and process, then manage prototyping, mass production, QC and export documentation end to end.
No middle layers between you and the production lines and die shop — real factory pricing.
OEM/ODM from drawings or samples; engineering feasibility review within 24 hours.
We broker new and used screw machines and nut formers to help small and mid-sized factories scale on budget.
Six major categories, OEM/ODM from drawings

For main forming in multi-station cold headers; cavity profile customized to wire diameter and fastener spec.

Designed for high-speed, high-volume screw lines to extend die-change intervals.

Modular construction lowers tooling cost and simplifies repair/replacement.

Used for wire cutting to length and head trimming before cold heading.

For knockout of nuts and screws; diameter and length customizable.
