INDEPENDENT THERMOFORMING EXPERTISE
Plug Assist Design.
Less Material.
Same Compression Strength.
The right plug assist material and geometry can improve wall thickness distribution, reduce material consumption and help maintain the required compression strength of thermoformed cups.
WHY PLUG DESIGN MATTERS
It Is Not Just About the Machine Settings.
Even a well-adjusted thermoforming machine cannot fully compensate for an unsuitable plug assist design.
The interaction between plug material, geometry and process conditions influences how material is distributed throughout the formed product.
Optimizing these factors can create opportunities to reduce material consumption without compromising the required cup performance.
THE BUSINESS IMPACT
Less Material Does Not Have to Mean Less Strength.
Plug assist optimization is about using material more effectively – not simply reducing sheet thickness.
The Right Plug Material
Plug material and surface properties influence the interaction with the heated sheet during forming.
The Right Plug Geometry
A suitable plug shape can support more effective material distribution in critical areas of the cup.
The Required Cup Strength
The goal is to identify material-saving opportunities while maintaining the required compression strength and product quality.
FROM SIMPLE TO ADVANCED
The Difference Is in the Details.
Not every cup requires the same plug assist design.
Depending on product geometry, material and production requirements, a more advanced plug design may offer significant optimization potential.
DTC evaluates the interaction between the existing tooling and the production process to identify practical improvement opportunities.

FREQUENTLY ASKED QUESTIONS
Plug Assist Design – FAQ
What is a plug assist in thermoforming?
A plug assist is a forming tool that mechanically pre-stretches the heated sheet before or during the forming process. Its design influences material distribution in the finished product.
Can plug assist design reduce material consumption?
Yes. Suitable plug material, geometry and process settings can improve material distribution and may create opportunities to reduce sheet thickness while maintaining required product performance.
Does a lighter cup automatically mean lower strength?
Not necessarily. Cup strength depends on several factors, including material properties, product geometry and wall thickness distribution. Any weight reduction must be validated against the required compression strength.
Can existing thermoforming plugs be optimized?
In many cases, existing tooling can be evaluated for improvement opportunities. The appropriate solution depends on the product, tooling condition and process requirements.
