Why Use Plug Materials?

CMT Materials has developed a wide range of plug materials. The right plug material helps save money in the thermoforming process by:

• Reducing starting sheet thickness by improving material distribution.
• Providing better part clarity.
• Reducing mark-off and chill marks.
• Eliminating plug cracking and chipping using tough syntactic materials.
• Improving part consistency with excellent detail in plug machining.
• Eliminating dust and tool wear when machining plugs.
• Providing greater durability and thermal stability.
• Reducing sheet sticking with smooth plug surfaces.
