What are the characteristics and features of Dongguan blow m

Dongguan blow molding products, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process was used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of the hollow container can reach thousands of liters, and some production has been controlled by computer. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The hollow containers obtained are widely used as industrial packaging containers. According to the parison manufacturing method, blow molding can be divided into extrusion blow molding and injection blow molding. Newly developed are multilayer blow molding and stretch blow molding.

Blow molded products are also called expansion joints, expansion joints, and compensators. They are divided into several types: ripple compensator, sleeve compensator, rotary compensator, square natural compensator, etc. Among them, corrugated compensator is more commonly used. To ensure the safe operation of the pipeline, it has the following functions:

1. Compensate the axial, lateral and angular thermal deformation of the absorption pipe.

2. Absorb equipment vibration to reduce the impact of equipment vibration on the pipeline.

3. Absorb the deformation of the pipeline caused by earthquakes and ground subsidence.

Features: Good flexibility, surface gloss, chemical resistance, acid and alkali resistance

Good blow molding starts with design. The design of blow-molded parts for plastic containers is the key to manufacturing competitive and high-quality containers. It is a systematic and comprehensive engineering plan. That is, first consider satisfying the use function; then select the material and determine the blow molding method (especially pay attention to the parting, demoulding, venting, etc. of the blow molded part); the structure size and technical requirements of the blow mold are determined later, Milky white PET blow molding processing, while also taking into account the technical characteristics of mold processing. The whole process must be closely integrated with production costs and efficiency.
