The development status of bottle blowing machine manufacturers in the market

Blow molding machine is a kind of equipment that makes plastic particles into hollow containers through the blow molding process. The more common models include the one-time hollow extrusion blower that uses PP and PE, and the two-time molding of PET, PC or PP. Injection stretch blow molding machine, as well as the newly developed multi-layer hollow extrusion blow and stretch blow molding.

The PET bottle blowing machine is divided into two types: rotary type and linear type according to the conveying mode when the preform is heated.

The rotary bottle blowing machine has high production capacity, high speed, complex design, and high price. A typical rotary blow molding machine is the SBO series of French SIDEL. Its SBO24 blow molding machine can produce more than 20,000 bottles per hour. At present, some Chinese blow molding machine manufacturers have successfully developed rotary blow molding machines. The speed reaches more than 8000 bottles per hour; the typical representatives of the linear blow molding machine are Japan's ASB and AOKI. Generally speaking, this kind of mechanical design is relatively simple, but the output will form a bottleneck, and it is difficult to exceed 6000 bottles per hour.

Temperature control is directly related to the uniformity of plasticization and is the key to the success or failure of blow molding products. The design and accuracy of the mold and hot runner also determine the quality of the product.

At present, China's injection stretch blowing equipment for PET bottle production is basically the home of imported products, especially in the production of high-speed and large-volume products, domestic equipment cannot compete. It is worth mentioning that there are few manufacturers that can produce large-capacity PET hot-fill bottle blow molding machines, and some manufacturers have achieved satisfactory results with their blow molding process.
