Blow molding solution required
(OP)
Blow Molding is not my area of expertise and would like some advice. My customer has approached me to design a new device which has a blow molded bottle as an accessory. Their competitors product has a PP bottle. Am I correct in holding the opinion that for conventional blow-moulding, a parison is extruded, nipped top and bottom and blown between two dies. This process is suited to PE, PP (as per my customers competitor sample. For more rigid materials e.g. PC and PET, the final product is blown from an injection moulded pre-form? My customer requires a more rigid material which has more clarity. What process should I be looking towards?

Most materials can be blow moulded either way. The limiting technical factor is melt strength or melt viscosity. With some materials, the extruded parison cannot support it's own weight, and it breaks and drops to the floor during processing
