What is made with extrusion blow molding?
Injection and stretch blow molding are often used to create water bottles, cosmetic containers, and other small hollow parts. Extrusion blow molding is used to create medium to large hollow parts with complex geometries or highly technical requirements such as DEF tanks, HVAC ducts, and lawn mower seats.
What kind of polymers are generally used in extrusion blow molding and injection blow molding?
High-density polyethylene (HDPE) is most often used within extrusion blow molding applications.
What products are made from blow moulding?
Examples of parts and products that are created using blow molding include water bottles, shampoo and other small bottles, automotive parts, stadium seating and chairs, watering cans, coolers, or any other type of hollow parts.
Which resin is typically used for extrusion blow molding?
The typical resins used in the extrusion blow molding process include: HDPE. LDPE. PP.
What is the difference between injection blow Moulding and extrusion blow Moulding?
Extrusion blow molding involves extruding heated material, injection blow molding involves injecting heated material into a mold, and injection-stretch blow molding involves stretching heated material.

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. It’s used in a vast array of products, including bottles for consumer liquids such as shampoo and motor oil, coolers, play structures, fuel tanks, industrial drums, and carrying cases.
What is LDPE plastic used for?
Low density polyethylene (LDPE). This clear or translucent plastic exhibits flexibility, chemical resistance, and waterproofing capabilities. It is used in the manufacture of a wide range of products, including grocery bags, plastic wrap and film, flexible packaging material, and injection molded parts.
What type of plastic is used in blow molding?
Polypropylene (PP) Polyethylene (HDPE, MDPE, LDPE) Nylon (PA)
What kind of plastic are blow molds made of?
High Density Polyethylene (HDPE) HDPE is the world’s #1 plastic and the most commonly blow molded plastic material.
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.
What plastic is used for blow molding?
High-Density Polyethylene (HDPE) HDPE’s desirable physical properties—including chemical resistance, temperature resistance, and a high strength-to-density ratio—make it one of the most popular blow molding materials.
