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;
