We can see many kinds of plastic products in our life, like bottle, cap, basket, tube, drum, light cover... and so on. HOW THEY ARE PRODUCED? They are produced by plastic machinery, like extrusion blow molding machine for hollow products, injection molding machine for injection parts, PET blowing machine for pet bottle, injection blow molding machine for small medical bottle.

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.

In recent years, with the rapid development of liquid drinks, the market demand for filling production line is booming, and the filling machine production line has become a solid backing of the beverage market. With the continuous advancement of science and technology and the continuous improvement of people's living standards, food, beverages, medicines, etc. have become an indispensable part of people's daily life. With the continuous gushing of these demands, major commodity companies have also swarmed, and the dazzling array of commodities dazzled us. How can a company stand in the market? Filling production line is a good choice for enterprises, because it can not only save the production cost of enterprises, but also can quickly produce to meet market demand. What are the benefits of the filling production line?

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.

The PET stretch automatic bottle blowing machine is an automatic intelligent bottle blowing machine. At present, it is mainly a two-step linear bottle blowing machine. The whole bottle blowing process is divided into preheating and bottle blowing molding. The detailed working principle is as follows
