Important index of hollow forming

release date:2020-05-22 00:00 source: http://www.dfwpreppers.com Click:

The technical level of hollow forming in Dalian varies greatly, and there are few enterprises with comprehensive strength in R & D, manufacturing and technical services. Some hollow equipment manufacturing enterprises have weak technical force and can not understand the plastic hollow molding process. The production equipment and molds can not meet the user's use requirements and raw material molding process requirements. The products produced are unqualified or can not stably produce qualified products.


Warpage deformation of extruded products in extrusion molding process refers to that the shape of extruded products deviates from the shape of die cavity. It is one of the common defects of plastic products. With the development of plastic industry, people have higher and higher requirements for the appearance and performance of plastic products. As one of the important indexes to evaluate product quality, warpage deformation has attracted more and more attention of mold designers.

With the development of plastic industry, people have higher and higher requirements for the appearance and performance of plastic products. As one of the important indexes to evaluate product quality, warpage deformation has attracted more and more attention of mold designers. For thermoformed products, some competitive pressure comes from Asian injection molding, structural foaming and polyurethane reaction injection molding manufacturers. Many professional manufacturers in North America simply produce some products with high complexity and strict tolerance, which are difficult for overseas competitors.


Hollow molding machine is the main equipment for processing thermoplastic into various plastic products by extrusion hollow molding. The nominal extrusion plasticizing capacity of the series machine is 25-55kg / h, the clamping force is 2.5-6kn, and the clamping force is designed to match the blowing force. It can be used for hollow extrusion molding of thermoplastic plastics (PE, PS, PP, PVC, etc.). There is still a stable market for chemical packaging barrels.
