Project Workflow
A Clear Process From Drawing to Shipment
DFM Review
We check your drawing, material, tolerance, product use, and production target before mold design starts.
Mold Design
We confirm mold structure, cavity layout, runner system, cooling, ejection, and key components.
Machining & Assembly
CNC, EDM, wire cutting, polishing, fitting, and assembly are tracked through each production stage.
Trial & Delivery
We run mold trials, provide samples and reports, make adjustments, then pack the mold for export shipment.
Quality Control
Quality Checks Built Into Every Stage
Reliable production starts before the first sample is molded. We control steel selection, machining accuracy, assembly fit, mold movement, cooling, sample appearance, and final packing.
- DFM and mold design review before manufacturing
- Mold steel and standard component confirmation
- In-process inspection during CNC, EDM, and fitting
- Mold trial with sample parts before shipment
- Dimensional report, trial report, and packing checklist available

FAQ
Questions Buyers Usually Ask Before Quoting
What do you need for a quotation?
Please send 2D or 3D drawings, sample photos, material, expected output, cavity requirement, and any machine information you already have.
Can you help if we only have a sample?
Yes. We can review sample photos first, then discuss reverse engineering, mold design, and production feasibility.
Do you provide trial samples?
Yes. We run mold trials before shipment and provide samples for your review. Adjustments can be made based on the trial result.
Can you supply machines with molds?
Yes. We can help match molds with blow molding machines, injection molding machines, filling equipment, labeling, and auxiliary systems.
