This machine is for testing the tension, fisheye and other property test items of PVC, PP, PETG and other plastic sheets. This machine adopts variable frequency driving for accurate control of roller speed. Hot oil drilled roller ensures high precision temperature control.

General design:
1. The mill consists mainly for rolls, frame, bearing, roll nip adjusting, screw, heating and cooling device, emergency stop, lubrication system and such sections as electrical controls and, etc.
2. The main electric motor arrives the front and rear rolls to rotate oppositely through reduar, driving geras and friction gears.

Features:
1. The rolls are made of chilled alloyed castiron. Their working surfaces are of high hardness and wear-resistant. The working temperature of the bored roll is controllable by steam, cooling water or oil that pass through them thus, to meet the requirements of milling process.
2. Roll nip adjustment is realized by hand or electricity which can obtain high accuracy and sensitivity

Others
Roller bearing can be divided into 3 kinds, nylon bush, bearing bush and copper bush.
Nip adjustment can be divided into manual and electric.
Stock blender can be added in light of your needs
