Plastic tray

Dalian plastic tray hollow blow molding method. The extrusion hollow blow molding of plastic tray is similar to the general blow molding method of hollow products. Because the products are large and double-sided, large extruder, die closing machine and die are needed. At present, the domestic hollow molding machine manufacturers have developed a super large hollow molding machine specialized in high-speed production of high-strength blow molding tray.

Hmwhdpe high-strength plastic is used for production. The top half is extruded fixed length and width plastic plate, the bottom half is large-scale vacuum plastic products; the top and bottom half are large-scale vacuum plastic products. Large vacuum equipment is needed for the production and molding of the method. The equipment cost is low, and the mold cost is also low, but the product wall thickness is uneven.

At present, the domestic hollow molding machine manufacturers have developed a super large hollow molding machine which is specialized in high-speed production of high-strength blow molding tray. Hmwhdpe high-strength plastic is used for production, with fast molding speed, good product quality, high strength, high rigidity and very long service life. Generally, the service life of blow molding tray can reach 5-10 years.
