Laboratory Calenders and Calendering Lines
The supplier:
Hapro
Hapro laboratory calenders are used to produce film or thin sheet by roll forming. The material is fed through a flat die and then passes through a roll system, where the required thickness and surface finish are formed.
Calendering solutions are particularly relevant for laboratory development of sheet and film materials, including PVC, PE, PP, PS, ABS, PET, PC and other polymers.
HAPRO Laboratory Calendering Line Video Overview
Main Tasks:
- laboratory production of sheet and film;
- evaluation of material formability;
- control of thickness, surface finish and transparency;
- comparison of formulations for sheet and film;
- preparation of samples for further testing.
Applications:
For PVC, this category is important when working with transparent sheet and film materials. For polyolefins, it can be an alternative or complement to flat-die film extrusion.
Key Specifications:
| Parameter | Value |
| FRC-I | 5 rolls and 3 mould temperature controllers |
| FRC-I application | transparent PVC sheet |
| 3-Roller Calender | flat die, 60 x 1.5 mm; rolls Ø110 mm |
| 3-Roller film thickness | 0.5-1.0 mm |
| 3-Roller film width | up to 50 mm |
| Roll gap | 0-2.5 mm |
Options and Configuration:
- visual film-quality inspection system;
- adjustable flat-die width;
- roll-unit selection for the material and required thickness.
