Main Equipment and Features of Plastic Pallet Boxes

(1) The barrel injection molding machine has the same structure as the conventional injection molding machine, but with a lower injection pressure. The screw screen aspect ratio can be small, but an excessively high shrinkage ratio is not desirable.

(2) Molds include injection molds and blow molding molds. The specifications and processing requirements for molds used in injection molding processes and for standard injection molding molds are identical, but the cores must be hollow to allow compressed air passage. Blow molding molds are identical to extrusion blow molding molds.

(3) Demolding and installation differ from extrusion blow molding; after the blow molding process is complete, open the blow molding mold, transport the core mold with the formed product to the demolding installation, and separate the product from the core mold using a demolding template.

注塑吹塑瓶 currently lack national or industry standards. The product specifications can be modified according to the blow-molding specifications for polyethylene pipe drums. However, the performance of injection-blowing hollow containers made from the same material is superior to that of blow-blow hollow containers.

Large hollow containers typically refer to various moldable drum containers, tanks, storage troughs, and boxes with a volume exceeding 50 liters. The main raw material is polyethylene resin, with the primary forming processes being extrusion blow molding and rotational molding.

The molding method for extrusion blow molding large containers is identical to that of plastic drums, with only some differences in raw materials and equipment.

The main raw materials for pallet boxes are generally a mixture of low-density polyethylene pipe resins or polyethylene sheet resins, while large containers consume primarily polyethylene sheet resins and high-molecular-weight polyethylene pipe resins.
