Lab Calender Machine

I. Product Overview

The lab calender machine is a small-scale device used for calendering and forming small batches of materials. It forms thin sheets or films of uniform thickness by rolling materials through multiple rollers, and can simulate mass-production calendering processes. It is widely applied in formula development and process parameter optimization in fields such as plastics, rubber, and films.

II. Key Features

  • Precise calendering: Roller gap adjustment range 0.01-2mm (accuracy ±0.005mm), ensuring uniform material thickness.
  • Controllable parameters: Roller temperature ranges from room temperature to 200℃ (accuracy ±1℃), and rotation speed is adjustable from 0.5-30rpm, adapting to various material properties.
  • Flexible operation: Compact design (floor area ≤0.5㎡), supporting manual/automatic modes, with quickly cleanable roller surfaces.

III. Common Specifications

  • Processing size: Maximum calendering width 50-200mm, suitable for materials with thickness 0.05-5mm (such as plastic granules, rubber sheets).
  • Equipment parameters: Number of rollers 2-4 (three rollers commonly used), power 0.5-3kW, power supply 220V/380V.
  • Safety configuration: Emergency stop button, anti-pinch protection; some models with online thickness detection function.

IV. Typical Applications

Thinning experiments of plastic films, calendering formula testing of rubber sheets, research on composite material lamination forming, and verification of hot-melt adhesive film calendering processes.
