In blow molding machines used for producing jerrycans and drums, specialized grippers are employed to pick up and handle these large, often heavy, and awkwardly shaped products. These grippers are designed to securely hold and transport the molded containers from the blow molding station to the cooling and ejection area.

 

•Function: These grippers have a mechanical clamping mechanism (like jaws or pincers) that securely grip the neck or sides of the container.

•Advantages: Mechanical grippers can handle heavier and more rigid products, like large plastic drums or jerrycans, which may not be suitable for vacuum-based handling.

•Application: Often used in situations where the containers are too large or have uneven surfaces that may not create a strong enough vacuum seal.
