Our Service

• Material-Specific Mold Design: Optimized mold configurations for ABS (impact resistance, good finish), PP (chemical resistance, flexibility), and PC (optical clarity, heat resistance)—including tailored gate designs, cooling layouts, and ejection systems for each material's unique properties
• High-Precision Manufacturing: State-of-the-art CNC equipment including 5-axis machining, EDM, and wire EDM achieves tolerances as tight as ±0.01mm for complex part geometries and critical mating surfaces
• Advanced Surface Finishing: Specialized polishing and texturing capabilities deliver specified surface finishes—from high-gloss SPI A1 for appearance parts to matte textures for functional components
• Optimized Cooling System Design: Conformal cooling channels and engineered baffles ensure uniform temperature distribution, reducing cycle times and minimizing warpage in thin-wall appliance components
• Durable Tool Steel Construction: Premium materials including H13, S136, and 420SS with heat treatment and optional PVD coatings ensure extended mold life through high-volume production

Our Advantages

1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
