BAKELITE INJECTION MOLDING MACHINE is a technique of injection molding used to manufacture castings from high-density metals like stainless steel, copper, brass etc. Injection molding uses solid plasticizer and binders to provide smooth finishing surfaces and products. Tasks can be accomplished quickly to meet customer demands. The process involves metal roll forming, binder and mold release process. These processes are performed in a process cycle with the help of machines.
Zhenfei BAKELITE INjection molding machine can be used for large production runs to produce hundreds of castings/pieces with different thickness and finish. These parts or products have to be produced in large volume for proper business. High quality products have to be produced for competitive business use. BAKELITE INJECTION MOLDING MACHINE is a system that uses a binder and a feed roller that feed into hopper. Feed rolls are made up of a cylindrical material having a small diameter that fits into the feed roller.
Feed roller moves continuously inside the injection molding unit and BAKELITE INJECTION MACHINE helps in producing smooth finished products. In the process cycle, the melted plastic product moves into the injector. The roller of the injection molding unit is fed with plastic material. Plastic material passes through the injection mold until it reaches the plasticized material in the injector nozzle. Here a thin film of melted plastic is collected on the surface of the injection mold while hot air is created inside the injector. This cycle keeps repeating.
After the plastic is collected in the injector, the hot air is directed inside the mold. This is done for several cycles so that the plastic is baked on the metal rollers and then cooled. Hot bakkelite solution is used for removing the cool plastic from the inside of the mold. The cooled bakkelite is removed and this material is collected on the edge of the mold. Bakkelite solution should be allowed to dry before the next cycle starts.
In addition, baking soda must be added in the mixing process. This is to increase the melting point of the product. The baking soda should be mixed well with the bakkelite. The mixing process should be done until there are no lumps on the product.
After this the mold should be cooled down. In this process the plastic resin pieces should not melt. A cooling process should be started by injecting the resin into the mold at a high speed. A high rate of flow of the mixture is required so that the baking soda will be absorbed inside the mold.
The mixing process is completed by injecting the bakkelite mixture at a low rate. Once the bakkelite has been fully integrated inside the mold then the process will be completed. The bakkelite will be cooled down and then it can be removed from the mold.
This process will be repeated many times until the right consistency of the product can be achieved. The amount of baking soda used should be determined by the type of the product. When this process is complete then the mold should be left to cool down. The cooled mold should then be cleaned and the excess baking soda should be removed.
The baking soda resin should be allowed to dry completely before it is exposed to any elements. In the injection molding machine this drying process can be done by injecting the mixture inside the mold at very high speed. The high speed will cause the baking soda to rise to the surface of the mold. The resin is dried with the help of a rotary tool and then it can be removed from the mold.
It is very important that the mold should be left to dry before it is being used for any other purpose. The mold should also be kept dry and there are various ways in which this can be done. One of the most common ways of drying the mold is by using pressurized air. If you are looking for a bakkelite injection molding machine for your manufacturing needs then you can search for them on the internet.
You should keep in mind that this type of machine does not have an extensive list of features. In fact, it is only capable of producing limited materials. There are however many manufacturers of this machine who manufacture the products in bulk. They can then sell the products individually. Some of these manufacturers include Benzema, Krones and Mimex. Before buying any injection molding machine you should ensure that you buy the products from a manufacturer that has a good reputation.
