1, product component: different components of the product on the warm runner requirements are completely different.
2, plastic raw materials: Different plastic materials have different processing variables, and those processing variables will affect the selection of warm runner system.
3, mold: What is the number of cavities? What is the nozzle spread distance? What kind of material is processed? These are the mold elements related to the selection of the warm runner system.
4, cycle cycle: fast production cycle means that the nozzle requirements are improved. For example, the nozzle needs to transfer heat accurately and be durable.
5, gate: For the point gate, in order to adhere to the outstanding heat balance in each molding cycle, the warm nozzle tip is necessary to have the function of melting materials and cooling sealing. The valve gate is mechanically sealed.
6, nozzles: Nozzles can generally be differentiated according to scale, temperature dispersion, physical characteristics, the material used (copper, steel, etc.) and the difficulty and price of maintenance.
7, runner: the use of warm runner system to avoid the generation of material, and then save the material, but also eliminate the previous need to remove the material by hand, manipulator or other methods.
8, temperature control: Each nozzle is necessary to be connected with a relatively complex temperature controller
9, the function of the injection molding machine: can install a given scale of the mold, supply to meet the closing force, operate according to the requirements of the cycle time, plasticize to meet the material and so on
10, product design: In general, 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 appearance is lubricated at the end of the molding and easy to mold, it is necessary to consider those elements in the structural design of the product.
