Extrusion Blow System Solutions

The blow molding process includes two major blow molding methods, extrusion blow molding and injection blow molding. The tubular plastic parisons obtained by extrusion or injection molding of thermoplastic resins are placed in the split mold while being heated (or heated to a softened state). Compressed air is introduced into the parison immediately after the mold is closed to blow the plastic parisons. And close to the inner wall of the mold, after cooling off, you get a variety of hollow products.
Blow molding is a molding process for producing hollow thin-walled parts from thermoplastic materials. Typical products are large-volume final consumer products such as bottles and containers. At present, the most widely used plastic types in production are PE, PP, and PVC.
Depending on the number of blow molding machines in the customer's workshop or the placement of the seats, a central or stand-alone transport solution can be proposed. The parts in contact with the raw materials are made of stainless steel and the filtering system of the delivery system, which effectively ensures that the raw materials are not contaminated during the transportation process.

In combination with extrusion blow molding, Hengyuan has multiple size feeders, and the 300g700g800g900g vacuum pump is continuously and efficiently transported, together with real-time detection or vacuum protection of the pressure differential of the filter device to ensure timely cleaning and protection of the vacuum pump.
Due to the large amount of extrusion blow molding materials used, the air volume and diameter of the vacuum blower must be taken into consideration, and each machine can be used in a sufficient amount to use the raw materials. It is also necessary to consider that raw material drawing occurs easily due to the original distance. The suction machine is small in size and strong in suction.
For the treatment of defective products, Hengyu pulverizer is suitable for the crushing and recycling of various plastic products, such as preforms, special bottles and so on. Centralized control design makes it easy to operate. Close to the open cutting room design, it has high strength, good toughness, and is not easy to break. It guarantees a good blade in the work, improves the quality and production of broken particles, and disassembly and maintenance. Maintenance is very convenient.
