1. Advantages of hot runner system:
1, save plastic raw materials: Because there is no cold runner in the pure hot runner mold, there is no production waste. This is particularly significant for applications where plastic is expensive. In fact, the major international hot runner manufacturers have developed rapidly in the era of expensive oil and plastic raw materials in the world. Because hot runner technology is an effective way to reduce the cost of materials.
Second, the characteristics of hot runner system:
(1) Plasticizing: that is, glass state, high elastic state (rubber state), viscous flow state (plasticizing state), decomposition state.
Glass state: 0 ~ T1, the molecule is in a frozen state, hard and brittle, and it is easy to break under pressure.
Viscous flow state (plasticized state) : T2 ~ T3, can be processed at will.
Decomposition state: T3, the plastic begins to crack, there is a gas decomposition, and even a burnt state.
(2) Forming conditions: the parts are finished after the hot runner mold molding, without trimming the gate and recycling the cold runner and other processes. Conducive to production automation. Many foreign product manufacturers combine hot runner with automation to greatly improve production efficiency.
Molding cycle: Because there is no limitation of the cooling time of the runner system, the parts can be ejects in time after forming and curing. Many thin-wall parts produced with hot runner molds can be formed in less than 5 seconds.
Extensive application: Many advanced plastic molding processes are developed on the basis of hot runner technology Such as PET preforming production, multi-color co-injection in the mold, multi-material co-injection process, STACKMOLD and so on.
