Twin blow

Plastic blow molding can be categorized into three types: injection blow molding, extrusion blow molding, and stretch blow molding. All of these processes consist of two steps, which vary the most in the early stages. The ultimate shape of the blow molded plastic depends on the shape of the mold cavity. While blow molded products come in an assortment of standard shapes and sizes, there are some products that can be made using custom blow molding, and are thus used for special applications.

twin sheet blow mold

twin sheet forming versus blow molding or rotational molding are typically cost- related. Twin sheet forming is very competi- tive with blow molding and much faster than rotational molding, especially with large, thick gauge products.
