Parts made from blow molding are plastic, hollow, and thin-walled, such as bottles and containers that 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.
What is the raw material used in blow molding?
Typical raw materials used are polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP).
What kind of plastic is used for blow molding?
HDPE
Low density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PP), Polycarbonate (PC), Polystyrene (PS), Co-polyester, Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), Nylon, Acrylonitrile Butadiene Styrene (ABS) are the main resins utilized with blow molding.
Can PVC be blow molded?
Polyvinyl Chloride (PVC) PVC is translucent and comes in rigid and soft forms — the soft resin is typically used in blow molding. Common applications include soft medical parts, bellows, and traffic cones.
Is polyethylene a common polymer for blow molding?
High Density Polyethylene (HDPE) HDPE is the world’s #1 plastic and the most commonly blow molded plastic material.
Can you blow mold polypropylene?
Blow Molding Materials In addition to HDPE blow molding, some of our most commonly recommended and requested materials and finishes include: Polypropylene (PP) Polyethylene (HDPE, MDPE, LDPE)
Which type of plastic is not used in blow molding?
Which of the following plastics is not used in blow molding? Explanation: For blowing processes, there are certain plastics only which are properly suited for the operation, while any other material might fail. Hence, for operating through blow molding process, polypropylene, polythene and PVC are used.
Is blow moulding expensive?
The costs in blow molding are lower as compared to injection molding. Machinery costs are typically lower as well. One-piece construction so that there’s no need to connect part halves, which can achieve shapes that injection molding cannot produce.
How much does a blow mold cost?
A single cavity, extrusion blow mold suitable to produce up to 100M units per year may cost as little as $3,000. An eight cavity, extrusion blow mold with automatic detabbing equipment may cost as much as $25,000 but may generate sufficient cost savings to return the investment within a short period.
