Blow Molding Capabilities
Blow molding is a manufacturing process used to create hollow plastic parts. A heated tube of plastic material (called a parison or preform) is inflated with air pressure inside a mold cavity, forcing the plastic against the mold walls to form the desired shape. There are three main types: extrusion blow molding, injection blow molding, and injection stretch blow molding. The process is responsible for producing most of the world's plastic bottles, containers, fuel tanks, and industrial ducting. Blow molding machines can produce thousands of parts per hour, making it extremely cost-effective for high-volume hollow part production.

What products are made with blow molding?
Blow molding produces bottles, containers, fuel tanks, drums, automotive ducts, industrial tanks, watering cans, kayaks, playground equipment, and other hollow plastic products. Virtually every plastic bottle you encounter was blow molded.
What is the difference between blow molding and injection molding?
Blow molding creates hollow parts by inflating plastic inside a mold. Injection molding creates solid parts by injecting plastic into a mold cavity. Blow molding is used for bottles and tanks; injection molding is used for solid components, caps, and housings.
How large of a part can be blow molded?
Blow molding can produce parts from small bottles (a few ounces) to very large tanks and containers (hundreds of gallons). Industrial blow molding machines can produce parts several feet in diameter and length.
What is extrusion blow molding vs. injection blow molding?
Extrusion blow molding extrudes a continuous parison that is then captured in the mold and inflated. Injection blow molding first injection-molds a preform, then inflates it. Extrusion blow molding is better for larger and irregularly shaped parts; injection blow molding offers more precision for smaller parts.
