Mold Design: Plastic and Silicone Tooling Developed Together, Right the First Time
Tooling is the largest single cost in mass output, and the stage where schedules most easily run out of control. One mistake at mold design stage often means tens of thousands of yuan in rework and weeks of delay. Once the structure is frozen, our mold design team steps in immediately, with plastic molds and silicone molds developed in parallel.
Plastic Mold Design
- Mold scheme definition - Based on order volume, product structure and cost target, we define cavity number and layout, gate position and cooling channel arrangement.
- Mold flow analysis - Filling, packing and cooling are simulated before steel is cut to predict shrinkage, warpage and weld line positions, so gate and cooling design can be adjusted in advance.
- Tooling assembly and tolerance - Core and cavity inserts, sliders, lifters and ejection are designed together with a tolerance chain that keeps a stable fit over hundreds of thousands of cycles.
Silicone Mold Design
- Hardness driven design - Mask skirts, mouthpieces and foot pockets are designed by hardness and elongation, so the mold matches the actual stretch and compression behavior of the material.
- Compression and injection options - We select compression or injection tooling by part shape, annual volume and surface requirement, and quote the cost difference before you commit.
- Trial run records - First shot assessment, dimension report and adjustment log are documented and handed over together with the samples.
FAQ
Q: Who owns the mold?
A: Mold ownership and exclusivity are agreed in the contract. We support regional exclusivity and can offer a buy-out arrangement.
Q: Can you build tooling from my own design files?
A: Yes. We review your files first for moldability, give feedback on draft, wall thickness and parting line, and then proceed to tooling design.
