The difference between extrusion blow molding machine and PET blow molding machine. Extrusion Blow molding machine and PET blow molding machine are two kinds of equipment that people often confuse. Many people think that these two kinds of equipment are the same, but they are really different. This article will take everyone to understand the difference between extrusion blow molding machine and plastic bottle blow molding machine.

Plastic blow molding machine is a relatively common type of equipment, which can be used to produce large multi-layer blow molding equipment, which is a common cause of failure of plastic blow molding machines.

Extrusion blow molding is used in large-scale hollow blow molding. For large products, there are two key molding technologies. 1. It is required to quickly provide the amount of melt required for the product, and reduce the drop and caliber of the parison caused by the large volume and dead weight; 2. The cooling of large products can be long, and the extruder cannot be continuously performed, so the head with a storage cylinder is developed. Hollow blister products with a volume exceeding 20L are called large hollow blow molded containers.

What is the process of blow moulding?The process of extrusion blow molding generally includes 6 steps. Hollow blow molding machine is a kind of extrusion or injection molding of thermoplastic resin or plastic, and then obtain the tubular plastic parison, which is placed in the split mold after being heated to a softened state. After the mold closing mechanism drives the mold to close, immediately Compressed air is passed into the parison to inflate the plastic parison and adhere to the inner wall of the mold. After cooling, the mold is released to make various hollow products.

Extrsuion blow molding machine can produce IBC tank, water drum ,hdpe barrel and so on. IBC Tank Blow Molding Machine. Machine Applications: 1. IBC tank 1000L with 1-3 layer. 2. Power supply 380~415v, according to requirements 3. Suitable raw material: HDPE/HMWHDPE.

How to improve quality of HDPE plastic hollow product from blow molding machine? Blow molding machines are so important to industrial production as everyone knows, lot of plastic bottles are made by blow molding, and the most normal type is extrusion blow molding machine. During production inevitabl
