Weight Reduction in Blow Molding Containers

There are many opportunities today that exist in reducing a containers weight, often referred to as “light weighting”. The challenge lies in designing a container along with the tooling that allows for weight reduction, without sacrificing the containers aesthetic appeal, top load requirement, impact performance and stability.  Industry experts have dedicated a significant amount of time to mold engineering design and researching “light weighting”.

What is blow molding?

Blow molding is the process of forming a molten tube (referred to as the parison or preform) of thermoplastic material (polymer or resin) and placing the parison or preform within a mold cavity and inflating the tube with compressed air, to take the shape of the cavity and cool the part before removing from the mold.
