Choose cosmetics packaging production embryos die: start from know hot runner nozzle

Is what affect the choice of the hot runner nozzle, I a little to know the following: the quality of the product, product design, plastic raw materials, molds, cycle, gate, nozzle, flow, temperature controller and the performance of the injection molding machine, and so on. When we have a very accurate knowledge of these later, will be able to choose the appropriate for its hot runner nozzle. The following simple introduce those elements:

1, the weight of the product: products with different weight to the requirements of the hot runner is completely different.

2, plastic raw materials: different plastic raw materials with different processing variables, and the processing variables will affect the choice of the hot runner system.

3, mold: as cavity number is how much? Distribution of the nozzle distance? What kind of material processing? Etc. These are related to the hot runner system of mold elements.

4, cycle: fast production cycle of the means of improvement of nozzle. Nozzle, for example, to transfer heat accurately, and durable.

5, gate: for point gate, in order to keep good thermal balance in each molding cycle, the heat flux recommand must have the function of the melt and cooling the sealing material. And the gate valve type, the use of the mechanical method to seal the gate.

6, nozzle, the nozzle can generally be used according to the size, temperature distribution, physical characteristics, materials ( Copper, steel, etc. ) As well as the ease of maintenance and price.

7, port: the use of hot runner system to avoid to produce material, thus saves raw material, at the same time saves ever need by manual, mechanical, or other ways to remove material to process.

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

9, the performance of the injection molding machine, can install a given size of the mould, provide adequate clamping force, according to the requirements of the cycle time of operation, plasticizing enough materials, etc.

10, product design: generally speaking, we all know that the product design is done first, but eventually forming was done in the mould of hot flow path. In order to ensure smooth when it was over, the product appearance, easy to die, must consider those factors on the structure of the product design.
