Smart Manufacturing Solutions For Polyurethane Resin Production Line

Polyurethane resin (PU resin) is a polymer material produced by the reaction of polyols and isocyanates. Due to its excellent elasticity, abrasion resistance, adhesion, and chemical stability, it is widely used in:

Adhesives and sealants
Coatings and paints
Elastomers and shoe sole materials
Electronic potting compounds and composite materials
Synthetic leather and textile coatings

With the development of new energy vehicles, building energy conservation and electronic materials, the polyurethane resin market continues to grow, and the demand for stable, energy-saving and automated production equipment is increasing.

Polyurethane resin production line is equipped with an intelligent PLC system, which can realize fully automatic closed-loop control of temperature, pressure and stirring speed, making the polyurethane reaction process more precise and stable and avoiding human error.

JCT's polyurethane resin production line for customers employ an automated metering and feeding system, with raw material ratio accuracy controllable within ±0.5%, significantly improving formula consistency.

The equipment adopts a high-efficiency heat transfer oil system and multi-stage temperature control technology to achieve rapid heating and constant temperature control, which can improve the energy saving rate by 15%.

To address the high viscosity of polyurethane resin, JCT developed a planetary dynamic mixing system to ensure uniform mixing, no bubbles, and no residue.

robotic arm

Polyurethane resin production line is equipped with data acquisition and remote monitoring functions, allowing customers to monitor the production status in real time via computer or mobile phone, thus achieving digital management of the factory.

The entire polyurethane resin production line adopts a modular design, allowing customers to expand or upgrade different modules according to their needs, enabling flexible production of multiple formulas.
