BLOW MOLDING

Blow Molding

A manufacturing process that is used to create hollow, thin-walled plastic parts.

Advantages

• Tooling is cheaper than Injection Molding
• Suitable for low and high production rates
• Various types of materials to choose from
• Flexibility for product revisions
• Faster Cycle Time
• One piece construction
• No cores are needed for irregular shapes
• Excellent stress and crack resistance
• Aluminum tools are less costly
• High part performance under pressure

Thermoplastic Materials Used

• Low-Density Polyethylene (LDPE)
• High-Density Polyethylene (HDPE)
• Polyethylene Terephthalate (PET)
• Polypropylene (PP)
• Polyvinyl Chloride (PVC)

Applications

Plastic, hollow, and thin-walled, such as bottles and containers are available in a variety of shapes and sizes. Small products may include bottles for water, liquid soap, shampoo, motor oil, and milk, while larger containers include plastic drums, tubs, and storage tanks.
