OPTIMUM PLUG ASSIST MATERIAL FOR THERMOFORMING

CGP Europe designs and manufactures high quality, innovative tooling materials used in the thermoforming industry.

What is Optiform® ?

OptiForm® is the plug assist family materials developed by CGP Europe to combine the toughness of engineering thermoplastics with the low thermal conductivity of a syntactic foam. OptiForm® Plug assists will resist the chips and dings associated with production abuse while reducing mark-off and sticking of difficult to process polymers. OptiForm® Materials maintains the high thermal stability required to process today’s thermoformed polymers. In addition, OptiForm® Materials eliminates the machining difficulties of conventional syntactic foams.

The range of product that does not produce dust during machining and finishing of plugs !

Applications

OPTIFORM® may be used in a wide variety of applications on sheet-fed, rotary, or in-line machines. It may also be used with most commonly thermoformed materials, and has proven quite effective with polypropylene and other polyolefins. With PP & PET we will give better productivity than any other epoxy syntactic.

High Toughness & Durability

With high toughness, machine downtime due to damaged plugs is reduced. Less downtime, lower costs, more consistent quality.

Superb Machinability

No dust collection equipment or respirators are required due to the large, non-abrasive chips. Plugs can be machined over three times faster than syntactic foam due to the easy chip formation.

Excellent Temperature Resistance

OPTIFORM® is specially formulated for service up to 180°C with minimal loss in mechanical properties.

Shapes and Sizes

The material is provided in standard sized rods or sheets, but may be custom molded to meet your specific needs.

WHAT IS PLUG ASSIST ?

Plug assist is used to pre-stretch the heated plastic sheet inside the mold cavity before turning on vacuum during the thermoforming process. The pre-stretching aims at improving the thickness distribution and lots of other parameters (cycle time, mark-off, part clarity, starting gauge…).

Plugs have a geometry usually from 10 to 30% smaller than the mold cavity. They have to be made with low thermal conductivity materials such as syntactic foam otherwise they have to be heated.

The four most important parameters to take into account to get the best results with plug assist is:
