Our blow molding process produces custom prototypes and end-use production parts in 15 days or less. We use aluminum molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock more than 100 different thermoplastic resins.
How Does Plastic Blow Molding Work?
Blow molding, also called blow forming, is a manufacturing process that is conducted by using thermoplastics by which hollow plastic profiles are formed. Blow molding process at BEPL begins with applying heat energy to the thermoplastic resins thus which converts them into a molten state and forming them into a parison or perform.
The parson is a tubular piece of plastic with a hole in one end in which compressed air is released. The compressed air expands the parson into the female mold cavity, while the pressure of the compressed air is maintained for a predetermined period of time, thus allowing the parison to expand and take the shape of the mold cavity. Once the plastic has cooled the mold is opened and the part is ejected.
Molding Options: Prototyping or On-demand Manufacturing?
Consider part quantities, lifetime maintenance, level of inspection, and cost when determining which option is right for blow molding.
