Bakelite Injection Molding Machine Bakelite, also known as bakelite, also known as phenolic molding, is a thermosetting plastic with high impact toughness, stable quality, corrosion resistance, heat resistance and low temperature. Generally speaking, the process of Dewei forging bakelite Injection Molding Machine brand is divided into the following processes. You can have a look together to better understand the knowledge of bakelite injection molding.

1. Bakelite mold heating
Unlike Plastic Mold, bakelite mold can be produced after being put on the machine. It takes a long time to heat up bakelite mold.
2. Temperature rise of bakelite injection molding material
The customized material of bakelite injection molding machine is generally powder. Under the friction formed by the barrel heating device and the screw, the thermosetting plastic in the barrel is melted by heat to achieve the effect of pre-setting plastic material.
3. Injection molding of bakelite products
After the completion of pre-molding, the mold closes, the screw rod starts to inject, and the molten material is pushed by the screw from the barrel nozzle through the main channel, the diversion channel and the gate of the mold into the mold core, and the mold core is fully filled. Because the melted material is cut and heated during injection molding and the mold is at high temperature, the temperature of the melted material rises rapidly into a fast response situation. The injection time of bakelite products is different from that of plastic products, and the injection time of bakelite products is relatively long.
4. Dry and solid under pressure
After injection, it will enter the pressure maintaining state immediately. The effect of pressure maintaining has two aspects: one is shrinkage, and the other is to ensure that the product structure produced by the bakelite injection molding machine manufacturer can be close and firm. After the completion of pressure maintaining, it will be delayed for a period of time, waiting for the material to be completely dry and solid, and then the product will be finalized.
5. Ejection of bakelite products
Open the mold to eject the finished product, clean the mold, and wait for the next the first mock examination product to go out.
XCMG QXZ5A guardrail cleaning vehicle designed to complete the sanitation family Tim Xintian
Recently, the XCMG sanitation QXZ5A fence cleaning vehicle was designed and put into tight trial production. QXZ5A fence cleaning car is a new product designed and developed based on the increasing demand for guardrail cleaning in the city. It is mainly used for guardrail cleaning and urban road isolation fence cleaning, as well as for cleaning industrial drainage pipes and walls, etc. Similar products with lighter weight, larger volume, better cleaning characteristics. The fence cleaning vehicle will form XCMG's urban road cleaning equipment with the existing cleaning products, helping to create a more competitive environmental sanitation solution, and has a broad market prospect.
