The forming of blow molded products consists of four important stages. Fully mastering these four key stages can greatly improve product quality.

The entire forming process can be divided into four phases: The first is the parison forming stage. In this stage, an extruder is used to complete material conveying, mixing and other technical processes.

The second is the extrusion and blanking stage. At this moment, the parison is prone to swelling and sagging. Therefore, the discharging speed must be strictly controlled during blanking.

The third is the parison pre-blowing stage. Its main function is to prevent internal contact and adhesion of the parison, and effectively improve the wall thickness uniformity of the finished product.

The fourth is the high-pressure blowing stage. The parison is inflated under high pressure, making the material closely fit the mold cavity to complete the final shaping of the blow molded product.

Blow molding technology has gradually matured with the rapid development of industrial technology and machinery manufacturing, and is now widely applied in various industries. Many daily necessities in our life are also manufactured by blow molding, such as blow molded auto parts, blow molded toys and other products.

Integrated with modern design concepts, practical experience and advanced manufacturing technology, blow molding technology greatly improves the efficiency of every production link, and further enhances the market competitiveness of blow molded products.
