Blow Molding
Blow molding is a plastic manufacturing process used to produce hollow components by expanding heated polymer material against a mold cavity. It is commonly used for bottles, containers, tanks, ducts, and industrial products requiring lightweight hollow geometries and repeatable production.

Manufacturing overview
Blow molding creates hollow plastic products by introducing pressurized air into a heated polymer preform or parison.
Common technologies include extrusion blow molding, injection blow molding, and injection stretch blow molding.
Typical applications include chemical containers, bottles, reservoirs, automotive ducts, and industrial hollow components.
Suitable materials include HDPE, PET, polypropylene, and selected other thermoplastics, depending on the process.
Technology selection depends on component geometry, neck finish, material properties, wall thickness, and production volume.
Design considerations include wall thickness distribution, parting lines, pinch-off regions, material shrinkage, and mold design.
Buyers should provide CAD models, polymer grades, nominal capacity, dimensional requirements, quantities, and functional specifications.
Where applicable, requirements may include leak resistance, pressure performance, chemical compatibility, and regulatory compliance.
Quality control may include dimensional inspection, wall thickness measurement, leak testing, drop testing, and visual assessment.
