Sell Three Roller Calendar – High Precision Calender Machine for Plastic Sheets

DESCRIPTION / TECHNICAL SPECIFICATIONS

In the plastic sheet production process, the calendaring stage is a critical phase that determines the flatness, thickness, and surface quality of the final product. Our Three Roller Calendar serves as a high-precision machinery solution designed to deliver flawless plastic sheet finishes. Utilizing a vertical configuration with a "Down in and Up out" material flow method, this machine ensures stable control during every cooling and pressing stage.

The core strength of this unit lies in its premium component quality. Each roller features a 400 mm diameter with a Chromium coated layer of $\ge 0.08\text{ mm}$ for superior corrosion resistance and extremely low surface roughness ($\le Ra 0.025\mu\text{m}$). Supported by a base material hardness of $\ge HRC50$ and high-grade Japan NSK Bearings, this machine guarantees long-term durability even under continuous heavy-duty operations.

The drive system is powered by high-quality motors controlled by an ABB Inverter for precise speed regulation. Furthermore, the gap adjustment mechanism between rollers utilizes mechanical control via a worm and worm gear system, allowing operators to make fine adjustments to achieve exact sheet thickness. This unit is an essential investment for factories prioritizing visual quality and dimensional accuracy in their plastic sheet products.
