Blow molding is the art and science of making the hollow plastic containers that are indispensable parts of everyday life. Common processing techniques such as extrusion, stretch blow, injection and co-extrusion are all utilized in forming these parts.

Whether it is a diverse and complex part that requires high performance such as an elastically functional automotive component; or a high-volume hollow piece such as a single-serve PET water bottle, the front-end blow molding process still requires an exacting thermal solution.
Regardless of your resin choice or final part shape, Watlow has an extensive offering of heaters, sensors and controllers to meet the application requirements.
A few examples of blow molded applications include:
