1. Product weight: different weight products have completely different requirements for the warm runner.

2. Plastic raw materials: Different plastic materials have different processing variables, and those processing variables will affect the selection of the warm runner system.

3. Mold: What is the number of image cavities? What is the spreading distance of the nozzles? What kind of data is processed? These are all mold elements related to the optional warm runner system.

4. Cycle cycle: Fast production cycle means higher requirements for nozzles. For example, the nozzle must transfer heat accurately and be durable.

5. Gate: Regarding the point gate, in order to maintain outstanding heat balance in each molding cycle, the tip of the warming nozzle must have the functions of melting the material and cooling and sealing. The valve gate uses a mechanical method to seal the gate.

6. Nozzles: nozzles can generally be distinguished by size, temperature distribution, physical characteristics, materials used (copper, steel, etc.), and the difficulty and price of maintenance.

7. Runner: The use of the warm runner system avoids the production of handles, and then saves materials, and at the same time eliminates the need to remove the handles by manual, mechanical or other methods.

8. Temperature control: each nozzle must be connected to a relatively complex temperature controller

9. The function of the injection molding machine: it can install the mold of a given size, supply the required clamping force, operate according to the requirements of the cycle time, plasticize the material that meets the requirements, etc.

10. Product design: Generally speaking, we all know that product design is completed first, but the final molding is completed in the warm runner mold. In order to ensure that the product has a lubricated appearance at the end of molding and is easy to mold out, it is necessary to consider those elements in the structural design of the product.
