Temperature-Controlled Adhesive Hose for Solvent-Free Laminating Systems

Introduction

A solvent-free laminating machine heated hose is designed to transfer temperature-sensitive adhesive between the supply unit, metering system, mixing section and coating unit of a solvent-free laminator.

Solvent-free laminating adhesives are highly dependent on temperature. When the adhesive cools inside the transfer line, its viscosity may increase, resulting in unstable flow, higher pump pressure, inaccurate metering and inconsistent coating performance.

Shenzhen Jingcheng High-tech manufactures customized heated hose assemblies for domestic and imported solvent-free laminating machines. Hose length, inner diameter, sensor, voltage, heating power, fluid fittings and electrical connectors can all be customized according to the equipment.

Why Solvent-Free Laminating Equipment Needs a Heated Hose

During solvent-free lamination, adhesive temperature affects:

• Material viscosity

• Metering accuracy

• Component ratio

• Mixing stability

• Coating uniformity

• Pump pressure

• Production speed

• Final laminate quality

An ordinary insulated hose can slow heat loss, but it cannot actively compensate for the temperature lost during transfer.

An electrically heated adhesive hose continuously supplies heat along the material path, helping maintain more stable adhesive conditions between different machine sections.

Product Structure

A complete solvent-free laminator heated hose may include:

• Adhesive-compatible material-contact inner hose

• Pressure reinforcement layer

• Uniformly distributed heating elements

• High-efficiency thermal insulation

• Protective outer covering

• Temperature sensor

• Machine-side fluid fitting

• Outlet-side fitting

• Electrical cable and connector

The final construction must be selected according to adhesive type, operating temperature, pressure, viscosity and equipment interface.

Key Features

Stable Heating up to 230°C

The product shown in the catalog supports temperatures up to 230°C.

The actual working temperature should be selected according to the adhesive supplier’s processing recommendation and the final hose construction.

Uniformly Distributed Heating Elements

Uniform heating helps minimize cold spots and temperature differences along the hose.

This supports more stable adhesive viscosity and flow.

High-Efficiency Thermal Insulation

The insulation layer reduces heat loss between the adhesive supply, metering and coating sections.

Compatible With Domestic and Imported Laminators

The hose can be customized for different solvent-free laminating equipment using original samples, drawings, connector measurements or machine information.

Custom Sensor and Electrical Configuration

Available configurations may include:

• PT100

• PT1000

• J-type thermocouple

• K-type thermocouple

• Custom voltage

• Custom heating power

• Equipment-specific electrical plugs

• Custom pin arrangements
