Hot runner technology has become an important field of plastic injection moulding technology with its unique technical advantages such as cost saving and shortening moulding cycle. Benefits of hot runner technology compared with conventional cold runner:
1. Save raw materials and reduce costs.
2. Shorten the forming cycle and improve the efficiency of the machine.
3. Improve the surface quality and mechanical properties of products.
4. Point gate can be used without using three-plate die.
5. The single product can be economically moulded by side gate.
6. Improve the degree of automation;
7. Needle valve gate can be used to control the freezing of the gate.
8. The quality of injection parts of multi-cavity mould is the same.
9. Improve the surface aesthetics of injection moulded products.
