We have made 2K molds, over-mold, multi-cavity molds, high polishing molds, stack molds, and insert molds.
We didn’t outsource the whole set mold, and the non-critical parts have stable suppliers.
We have regular training for the suppliers. The suppliers are well understanding of our standards and have a special project engineer to follow up. In addition, all outsourcing components must be 100% inspected by the quality department before being used.

No, we don’t have, but we have cooperated mold testing supplier which is near our factory, they have 2K injection machines to do mold testing.
Yes, we do. It is normally used on the mold with a tight cycle time and high requirement of deflection, cycle time could be reduced by more than 20%.
3D printing mold has to use pure water for cooling to avoid cooling channel rust
Conformal cooling technology can’t be used on mirror polish or transparent molds, however, diffusion cooling technology can be used on mirror polish or transparent molds.

Yes, but the temperature has to be less than 400°C.
Yes, we can.
We have stable raw material suppliers, they have to supply resin certification.
We will inform customers remaining raw material, and customers can ship it back, or keep it in HJ’s warehouse for coming projects. It will be disposed of if raw materials are stored at HJ’s warehouse for more than a year.
We choose the most suitable steels based on the product characteristics and resin to extend the life of the mold. For example:
Corrosion resistance steel: POLMAX; S-STAR; S136H SUP; S136; 2083
High gloss: 1.2083ESR; S136; NAK80; 1.2344ESR
Electroplating: 1.2343ESR
Wear resistance: 1.2344ESR; H13
All steel is imported from well-known international steel suppliers.
Each steel has a corresponding steel certificate.
Each steel hardness must be tested after returning to the factory.
Yes, every mold has steel certificates and heat treatment reports for full hardened mold.
