Blow Molding – from small part design to very large parts-including up to the size of large chemical tanks and septic tanks. Blow molding is in 3 categories: small to medium parts, medium to large parts, and extreme large parts. The category will depend on part size and the machine size required to mold the part.
Injection Molding – The same discussions as blow molding-material, quantities and including tool costs from US and foreign sources.
Extrusion – There are many forms of extrusion. Profile size and complexity as well as material to meet the product requirements contribute to vendor selection.
Roto-Molding – can be small to very large parts that are provided in quantities often determined by color changes, number of tools required to meet demand, and often vessels that are used in the storage of any liquid.
Vacuum Forming – small to large parts that utilize both prototype and production tooling. Both single sheet and TWIN sheet production depending on the structural and product application requirements. Oven machine size comes into play and whether single or twin sheet manufacturing is needed.
