Injection Blow Molding (IBM) Machine: Know Your Part Well Before Sizing Machine and Tooling

The injection blow molding process is a good, reliable choice for producing challenging and delicate parts. Many factors need to be taken into account before purchasing the injection blow molding equipment, including technology and price.

Prior to selecting the blow molding resin, you also need to know the part’s specifications, the final weight, and the shot size. Typical IBM resins are HDPE, LDPE, PP, Nylon, etc. 

Cycle time and shot size affect the IBM machine’s output. To conservatively predict the IBM machine’s maximum output, assume 90 percent of its highest screw speed. The extruder should have a low melt temperature, as heat increases during the cycle time.
