Blow molding is a plastic processing technique that primarily utilizes blow molding machines to heat and melt plastic pellets, then shape them into hollow products through blowing. Below are some of the main steps involved in blow molding processing:

Material Preparation: Select appropriate plastic materials and mix colors and additives according to product requirements.

Heating and Melting: Plastic raw materials are added to the hopper of the blow molding machine, which is heated to melt into a flowing state.

Blow Molding: Molten plastic is extruded through the die of a blow molding machine while air is blown in, forming hollow products.

Cooling and Setting: After blowing molding, the products enter the cooling unit, where they are cooled to set their shape.

Trimming and Inspection: The products are trimmed to remove excess materials, followed by quality inspections to ensure compliance with standards.
