Madina Blow Moulding
Blow molding is a manufacturing process by which hollow plastic parts are formed. The blow molding process begins with melting down the plastic and forming it into parison. The parison is a tube, like piece of plastic with a hole in one end through which compressed air can pass.
The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected.
Blow molding is a low pressure process, with typical blow air pressures of 25 to 150 psi. This low pressure process allows the production of economical low-force clamping stations. The resulting low stresses in the molded parts also help make the containers resistant to strain and environmental stress cracking.
We are manufacturing food grade products, such as Tank, Gallon, Household Silo, Container etc.
The particular materials that are generally blow molded are:
PET (Polyethylene Terephthalate)
HDPE (High Density Polyethylene)
HWPE (High Molecular Weight Polyethylene)
PPCP (Polypropylene Copolymer)
PVC (Polyvinyl Chloride)
