Industrial Laminating Machines by KUNTAI: From Textile Bonding to Ballistic Composites

JIANGSU KUNTAI MACHINERY CO.,LTD is a leading manufacturer of coating, laminating, impregnation, and cutting machinery for technical textiles and composites, headquartered in Yancheng, Jiangsu, China. With over 40 years of experience and a 30,000 m² facility, Kuntai supplies laminating machines for applications ranging from garment and upholstery bonding to high‑performance ballistic prepreg production.

What Is an Industrial Laminating Machine?

An industrial laminating machine bonds two or more layers of material – fabric, foam, film, nonwoven, or composite – through heat, pressure, or adhesive. Depending on the process, these machines can apply hot melt glue (PUR, PSA), flame lamination, dot coating, powder scattering, or double‑belt pressing. Kuntai offers a full range of laminating solutions from 1600 mm to 3400 mm working width, speeds up to 40 m/min, and heating via electricity or thermal oil.

Problem: How to Choose the Right Laminating Technology for Your Production?

Manufacturers in textiles, automotive, filtration, and protective equipment often struggle to find a single supplier that covers both conventional fabric-to-fabric lamination and advanced UHMWPE / aramid prepreg lines. Many companies need both reliable daily‑use machines and high‑precision equipment for ballistic composites. Kuntai addresses this with a product portfolio that spans from hot melt glue laminators to UD impregnation and crossply machines, all built under one roof.

Industry Background

The global laminating machines market was estimated at USD 786.5 million in 2026 and is projected to reach USD 1,356.7 million by 2033 (Coherent Market Insights). Asia‑Pacific already held a 72.70% share in the textile machinery market in 2025 (Fortune Business Insights), driven by automation growth in China. Simultaneously, the prepreg market – essential for ballistic and aerospace composites – was valued at USD 15.07 billion in 2024 (Maximize Market Research), showing strong pull from defense and aviation segments. Kuntai’s export ratio of 70% reflects this global demand, with machines shipped to North America, South America, Europe, South Asia, Africa, and the Middle East.

• PUR Laminating Machine (KT-PUR): Maximum width 2400 mm, speed 0–35 m/min, includes one gluing roller, PUR drum melter, oil heater, and humidifier. Ideal for fabric bonding with moisture‑curing PUR adhesives.
• Flatbed Laminating Machine (KT-PB): Heating zone 3 m, cooling zone 1.5 m, max temperature 230°C, power 230 kW. Suitable for high‑temperature lamination with flat pressure.
• Double Belt Press Laminator (KT-HY-H): Max temperature 250°C, used for automotive, filter, and insulation material manufacturing.
• Flame Laminating Machine (KT-HY): Gas‑fired (natural gas or liquefied gas), widths up to 3000 mm, speed 25 m/min. For automotive seat manufacturing.
• Dot Coating Laminating Machine (KT-DS): Coating width 1600–4500 mm, electric heating max 130°C. Designed for carpet manufacturing.
• Glue Spraying and Powder Scattering Machine (KT-SF): 6 glue spraying systems + 4 powder scattering systems, powder size 20–150 microns. For filter manufacturing.
• Lamination Machine for Textile (KT-FT-XC): Width 1600–3200 mm, speed 0–35 m/min, includes PUR drum melter. For general textile bonding.
• Fabric to Fabric Laminating Machine (KT-FT): Width up to 2400 mm, includes humidifier for PUR reaction.
• Hot Melt Coating Laminating Machine (KT-PUR-1800): For safety shoes manufacturing, glue roller for 25–110 g/m².

Advanced Composite Lines

• UHMWPE Prepreg Machine / Impregnation Machine (KT-LH-1800 & KT-YJ-1800): Roll surface 1800 mm, material width ≤1650 mm, water‑based adhesive, dipping/coating method, with 1080 yarn bobbins. Composite speed 5–11 m/min. Used for bulletproof vest, helmet, and plate manufacturing.
• UD Aramid Prepreg Machine (KT-LH-1800): Same platform as UHMWPE, producing unidirectional aramid prepreg.
• UD Crossply Machine (KT-LH-1800): 8000 KN hydraulic press, table 1700×1700 mm, thermal oil heating. Produces cross‑plies for ballistic panels.

Step-by-Step: How a Typical Kuntai Lamination Line Works

1. Unwinding: Material rolls are loaded on trolleys with air shafts (up to 4 sets).
2. Adhesive Application: For PUR/ hot melt lines, glue is melted in a drum melter (up to 200 kg) and applied via a single or multi-roller system.
3. Lamination: Substrates are fed through heated rollers (electric or thermal oil) at controlled speed and pressure.
4. Cooling & Curing: For flatbed and double‑belt presses, a cooling zone (up to 1.5 m) stabilizes the bond.
5. Rewinding: Finished laminate is collected on a second trolley or rewinder.
