An export injection mold manufacturer delivers not only a working tool but a package that another molder—or your own plant—can run: documentation, spares, water diagrams and validated process windows. Buyers shipping tools out of China should specify that package in the RFQ.

Export mold package checklist
- 2D mold layout and 3D tool data (as agreed).
- Bill of materials for plates, inserts and standard parts.
- Hot runner manufacturer manuals and wiring diagrams.
- Spare seals, heaters, thermocouples as contracted.
- Tryout report: parameters, cycle, photos of T samples.
- Steel certificates for cavities/cores when required.
Manufacturer evaluation criteria
| Area | What to verify |
|---|---|
| Engineering | DFM depth, moldflow if needed, English drawings |
| Machining | CNC/EDM capacity for your steel and tolerance |
| Tryout | Press tonnage range matching your part |
| Quality | ISO 9001:2015, inspection reports on T1 |
| Commercial | Ownership, storage, payment milestones |
Running parts in China vs exporting the tool
Many OEMs cut tools in Dongguan and run initial production locally for speed, then export the mold later. Same-factory molding simplifies first articles. If you will only export the tool, insist on a clean process sheet so foreign molders can restart without tribal knowledge.
Logistics notes
- Rust prevention and humidity control for ocean freight.
- Crate design for heavy molds and plate separation if needed.
- Customs HS codes and commercial invoice values for tools.

Documentation that foreign molders actually use
A thick folder of Chinese-only notes fails abroad. Require English process sheets: clamp force, temperatures, timers, velocities, and last known good shot weight. Include photos of gate trim standards and acceptable blush. Water circuit diagrams with numbered fittings save days of reverse engineering.
Spare parts lists should use global standard components where possible (ejector pins, leader pins, hot runner heaters) so replacements are available outside China. Proprietary unlabelled heaters create downtime.
If HC-Mold both builds and runs the mold for initial production, treat the first production lots as living documentation: freeze parameters after capability is shown, then export the tool with that frozen sheet. Buyers who skip this step often relearn the process under schedule pressure overseas.
Buyer checklist before you issue the PO
Confirm drawings are revision-controlled, materials are purchasable in China within your schedule, and inspection methods are agreed in writing. Ambiguity at PO stage becomes cost later. List secondary operations, packaging and labeling so they are not treated as free extras. If multiple factories are bidding, freeze the same specification package for all—do not let informal calls create hidden scope differences.
Align internal stakeholders: industrial design owns cosmetics, engineering owns function, procurement owns total cost and risk. A single RFQ owner should consolidate feedback so the manufacturer receives one voice. For export programs, involve logistics early on Incoterms preference and whether tools or finished goods will cross borders.

FAQ
Should I always export the mold?
Not always. Local production may be cheaper for ongoing volume if logistics and tariffs favor China-origin parts.
Who supplies hot runner brands?
Specify preferred brands in RFQ or accept factory-standard systems documented for serviceability.
Are tryout samples included?
Define T1 quantity and free correction rounds for mold-caused issues in the PO.
What files start an export mold quote?
STEP part, resin, volume, surface, and whether tool will ship abroad or run in China.
