Product Summary

The KT-LH-1800 is a high-performance UD prepreg impregnation machine developed for the production of unidirectional (UD) prepreg materials used in ballistic protection systems. With an equipment roll surface of 1800 mm and support for material widths up to 1650 mm, this machine is engineered to deliver consistent, high-quality impregnation for aramid and UHMWPE fibers. The system integrates water-based adhesive technology, advanced HMI+PLC control, and a robust thermal oil heating system to ensure stable production output. Whether you are manufacturing bulletproof vests, helmets, or ballistic plates, the KT-LH-1800 provides the precision, efficiency, and reliability required for demanding composite applications.

Key Selling Points

• Wide 1800mm roll surface – Supports material widths up to 1650mm, enabling high-volume production of wide-format UD prepregs and reducing material waste.
• Water-based adhesive system – Uses dipping and coating methods with water-based adhesives, offering an environmentally friendly and cost-effective alternative to solvent-based systems.
• Precision control with HMI+PLC – Combined variable frequency and servo drive provide accurate tension and speed control, ensuring uniform resin distribution and consistent prepreg quality.
• External circulating thermal oil roller – Equipped with a 60KW external mold oil heater, delivering stable and uniform heating for optimal resin curing and lamination.
• Friction mirror surface roller (level 14) – Achieves extremely smooth roller surfaces that minimize fiber damage and ensure superior surface finish of the prepreg.
• 1080 pcs yarn bobbins – Large bobbin capacity allows continuous production of multi-end UD fabrics, increasing efficiency and reducing downtime.

Technical Specifications

Models and Options

• Standard model: KT-LH-1800 (1800mm roll surface, 1650mm max material width)
• Additional configuration options may include custom glue pump systems and voltage stability packages to meet specific production requirements.

Materials and Structure

The machine frame and critical components are manufactured from carbon steel and SS304 stainless steel, providing excellent structural integrity and corrosion resistance. The roller surfaces are treated to a friction mirror level of 14, ensuring a smooth and durable finish that protects sensitive fibers during impregnation. The thermal oil system uses an external circulating heating circuit with a 60KW mold oil heater for uniform temperature distribution across the roller width.

Applications

The KT-LH-1800 is specifically designed for the production of ballistic UD prepregs used in:

• Bulletproof vests and body armor
• Ballistic helmets
• Ballistic plates and panels

It is also suitable for other technical textile applications where high-accuracy impregnation of UD fiber layers is required.

Customization

Kuntai supports customization to match your exact production environment. Based on your requirements, we can adapt the glue pump system, control software, heating capacity, and electrical components to ensure seamless integration. For facilities operating in low temperature or moderate humidity conditions, additional voltage stability features and special insulation options are available.

Case Study

A protective products company in Turkey, Czech Republic, India, and Russia has been using the KT-LH-1800 for more than 3 years. Over this period, 50 units have been deployed for producing bulletproof vests, helmets, and plates. The machines have demonstrated stable operation, long lifespan, and low maintenance requirements, confirming the reliability of Kuntai’s impregnation technology.
