Our Services
Single Cavity Mold
Single cavity molds usually are applied for small or medium mass production.Each injection produces only one part,so the mold cost is low but the production cost is high. Lead-time: around 3-5 weeks.
Multi Cavity Mold
Multi-cavity molds usually are applied for big mass production.Each injection produces several same parts,so the mold cost is high but the production cost is low. Lead-time: around 4-6 weeks.
Stack Mold
Our stack mold tooling is designed to increase your molding output and minimize part costs, with options for both equal and varying cavity numbers in each parting surface. Lead-time: around 4-6 weeks.
Family Mold
Family molds are a type of multi-cavity mold that allows for the production of different parts with varying shapes, sizes, and features in a single molding cycle. By using a family mold, we can increase production efficiency and reduce costs, as they can produce multiple parts simultaneously with one mold.

Mold Processing
MOLD MAKING IN-HOUSE
Our mold workshop is equipped with the latest machines, such as high-speed CNC machine tools, EDM wire cutting machines, and mirror processing sinker EDM machines, which help us to ensure that our molds are manufactured with the highest precision and high-quality surface finishes. Our shop has 30 skilled mold makers, most of whom have more than 10 years of experience in mold making, who are familiar with all the machining processes, cost every step of the way and can troubleshoot the mold making process.
CNC workshop
Our CNC workshop contains 10+ machining centers to accurately produce mold components within 0.05mm tolerance.
EDM workshop
10+ wire and sinker EDMs deliver precise cavities, pockets, and details down to 0.01mm tolerance.
Wire-cut workshop
High-speed wire EDMs with auto-thread capability provide efficient, accurate cutting of complex profiles.
Grinding workshop
Advanced grinding, lapping, and polishing machines create ultra-smooth mold core/cavity surfaces under 0.2μm Ra finish.
Quality Department
CMMs, projectors, vision systems, and lab testing rigorously inspect, validate, and verify mold tooling to certification standards.
Assembly Department
Assembly/testing validates aligned precision components for flawless mold performance and sampling.
Tooling Materials
We use high quality mold steels, selected based on hardness, polishability, corrosion resistance and manufacturability requirements. Our engineering experts specify the optimum grade for each mold component based on the material and process being produced.
