HDPE Blow Molding

What Is Blow Molding

Blow molding is a rapidly developing processing method for hollow plastic products. Blow molding is a manufacturing process in which molten plastic is blown into so that it contacts tht mold surface and cools to form a plastic product. Blow molded products are not only beautiful in appearance, but also durable. Meanwhile, the plastic surface is not compressed during the process, which can reduce product deformation and shrinkage, and it suitable for the production of products of various specifications and shapes.

HDPE Blow Molding

Plastic resins suitable for blow molding processing method include Polyethylene PEPVC resinpolypropylene PPpolyester resins, etc. Among them, HDPE has become the most widely used plastic resins in blow molding plastic products due to its good thermal stability and various modified products. The blow molding plastic products is generally divided into small blow molding, medium blow molding and large blow molding based on the volume of the container. This is also a common method for the classification of HDPE blow molding grade.

The large blow molding containers has stable performance and can withstand the overlapping of heavy objects, punctures, and corrosion in harsh environments.

Toys

The production process of blow molded toys is convenient and suitable for mass production. Blow molded toys can be made into various shapes and colors and are not easily broken even after being squeezed or bumped.

Medical supplies
