Stiffening Machine
GMA is experienced in PC, PP, PET hollow sheet stiffening.

Features:
- The equipment can be mountd on a used hollow sheet extruding machine from various countries, such as, Germany, Japan, Italy, etc. GMA has extensive experience in equipment installations.
- Thickness setting is conveniently controlled by computer without stopping the machine thereby reducing waste to minimum.
- When PP hollow sheet is produced through this power saving and space saving device, an extremely smooth sheet surface can be obtained without the need of drying oven treatment.
- The forming unit is manufactured from specially treated material assuring maximum wear resistance and deformation-free.
- Special temperature controlled water way allows temperature adjustment to meet various physical property requirements for different materials.
