BAKELITER INJECTION MOLDOING MACHINE
Bakelite, also known as bakelite, also known as phenolic molding, pet prefrom mould .is a thermosetting plastic with the advantages of high impact toughness, stable quality, corrosion resistance, heat and low temperature resistance, etc. Generally speaking, the process of Dulwich Forging Bakelite Injection Molding Machine brand is divided into the following processes, household plastic mold.you can take a look at it together, and you can better understand the knowledge of Bakelite injection molding machine.
1. Bakelite mold heatingBakelite molds are not like plastic molds, which can be produced after being put on the machine. Bakelite molds require a long heating time.
2. Heating of bakelite injection molding materials
Bakelite injection molding machine custom materials are generally powder. Under the friction formed by the barrel heating device and the screw, the thermosetting plastic in the barrel is melted to achieve the effect of pre-solidified plastic material.
3. Injection molding of bakelite products
After the pre-molding is finished, water bottle mold.the mold is closed, and the screw starts to inject. The molten material is driven by the screw from the nozzle of the barrel through the main channel, runner and gate of the mold and injects into the mold core and fills the mold core completely. Because the melted material is cut and heated during injection molding and the mold is at a high temperature, the temperature of the molten material rises rapidly and enters a fast response state. The injection molding time of bakelite products is different from that of plastic products. The injection molding time of bakelite products is longer .precision core parts.
4. Keep pressure and dry
Immediately after the injection, it enters the pressure-holding state. There are two effects of pressure-holding: one is to feed shrinkage, and the other is to ensure that the structure of the product produced by the bakelite injection molding machine manufacturer can be tight and firm. Dry and solidify, and make the product finalized.servo type injection molding machine.
5. Ejection of bakelite products
Open the mold to eject the finished product, clean the mold, and wait for the next mold to come out.
