Automatic Plastic Chair Injection Moulding Machine Big Size Plastic Injection Molding Machine

Adjust the pressure of the machine according to the molding needs to adapt to the required molding pressure. Start the machine and start the molding process. Under the action of heating and pressure, the raw materials gradually melt and flow, filling the mold cavity. After the plastic parts to be formed have cooled down, turn off the heating element to allow them to cool and solidify. After cooling the formed plastic parts, open the mold and take out the finished product. Check if the finished product meets the requirements, clean the mold and machine, and proceed to the next round of molding preparation.

Select suitable plastic raw materials for molding and prepare them according to the requirements of the molding machine. Ensure that the power switch of the molding machine is turned off, then turn on the main power switch of the machine. Adjust the heating temperature and time of the machine according to the requirements of the selected raw materials, and heat the heating element to the desired temperature. Put the prepared plastic raw materials into the feeding port to ensure that they evenly enter the feeding area.

Plastic injection molding machines inject molten plastic into molds through injection devices, suitable for producing various complex shaped plastic products. A plastic extrusion molding machine extrudes molten plastic through an extrusion device to form continuous plastic products, such as pipes, bars, etc. Plastic blow molding machines use compressed air to blow molten plastic into the desired shape of plastic products, suitable for producing hollow plastic products. Compressors and transfer molding machines are mainly used for the molding of thermosetting plastics, which solidify the plastic in the mold by applying pressure.

operational principle

Heating: Add plastic raw materials into the hopper of the molding machine, and use the heating system to bring the plastic to a molten state.

Melting: Plastic in the molten state is pushed into the mold through devices such as screws or plungers.

Forming: In a mold, molten plastic is subjected to pressure to fill the mold cavity, forming the desired shape of the plastic product.

Cooling: After a period of cooling, the molten plastic gradually solidifies, forming solid plastic products.

Remove: After the plastic product has completely cooled down, open the mold and remove the finished product.
