Nozzle: This is a customary name in Cantonese. It mainly refers to the molding of the gate and runner outside the product. Because the physical properties are consistent, the unqualified products and the nozzle are later smashed, and it is commonly known as the nozzle material.
Hui material: This is the Mandarin name for Shuikou material.
The nozzle material should also depend on the quality of the product used in its production. If it uses brand-new materials, it can be used to produce dark-colored products, preferably black. If it uses recycled materials In terms of production, only products with relatively low quality requirements can be produced; generally, the proportion of nozzle materials added should not be too large, about 25%.
Extended information:
For the nozzle material that can be used, the work orders generated will be different from those when the nozzle material is not used. There is a production work order for the nozzle material that can be used. The component corresponding to the work order must reflect the available nozzle material material number and usage, and the raw materials purchased in the order must be subtracted from the proportion of the available nozzle material, that is, only the BOM needs to be purchased. The amount of irreplaceable raw materials can be used.
Reuse of nozzle materials will reduce the performance of plastics, but using a hot runner system without nozzle materials can reduce the loss of raw materials, thereby reducing product costs. The temperature and pressure in the cavity are uniform, the plastic parts have small stress and uniform density. Under smaller injection pressure and shorter molding time, better products can be injection molded than ordinary injection molding systems.
