Production Process-Bottles

The raw materials we mainly use to make plastic bottles are polyester (PET), polyethylene (PE), polypropylene (PP), PS (polystyrene), Acrylic (acrylic acid). After adding the corresponding organic solvent, after being heated at a high temperature, the plastic container is blown, extruded or injection molded through a plastic mold.

The raw PET pellets are poured into the injection molding machine through the pipeline, the auger in the machine pushes the pellets into the heating tube, the heating tube melts the PET pellets, and then the machine combs the liquid, injects it into the mold, and the mold is completed.
The preform is cooled, the preform is heated in a cycle, the gear at the mouth of the bottle is stuck, and the high-temperature preform is sent to the mold. At the edge, the ice water cools, the edge temperature of the mold is lower, and the bottle is formed through the cold metal.

Blow Molding

blow molding

The preform is cooled, the preform is heated in a cycle, the gear at the mouth of the bottle is stuck, and the high-temperature preform is sent to the mold. At the edge, the ice water cools, the edge temperature of the mold is lower, and the bottle is formed through the cold metal.
It uses the thrust of the screw (or plunger) to heat the raw material, so that the plastic is melted in a flowing state and injected into the closed mold core. Driven by the screw or plunger of the injection machine, the injection system of the nozzle and the mold enters the mold cavity, and the product is obtained after drying and shaping.

It uses the thrust of the screw (or plunger) to heat the raw material, so that the plastic is melted in a flowing state and injected into the closed mold core. Driven by the screw or plunger of the injection machine, the injection system of the nozzle and the mold enters the mold cavity, and the product is obtained after drying and shaping.
Add the plastic raw material into the extruder, extrude the molten parison by heating, melting and plasticizing, and then put it into the bottle mold for inflation molding. , This process is mainly used to produce polyethylene PE.

Squeeze and Blow

PE machine - Production Process-Bottles

Add the plastic raw material into the extruder, extrude the molten parison by heating, melting and plasticizing, and then put it into the bottle mold for inflation molding. , This process is mainly used to produce polyethylene PE.
The plastic raw material is injected into a tubular parison by an injection molding machine, and then put into a bottle mold for stretch blow molding, and the finished product is obtained after cooling. This process is mainly used to produce PET plastic bottles.
