Core Production Process
Standard Three-Step Forming Process
1. Substrate Extrusion: LDPE extrusion line produces high-purity PE backing film with uniform thickness
2. Irradiation Crosslinking: A professional electron accelerator irradiates the substrate to endow flame retardancy and high tensile strength
3. Online Lamination: Secondary stretching shaping, then real-time bonding with imported special hot melt adhesive, ensuring high peel strength and qualified shrinkage rate
Three-Layer Fiberglass Reinforced Process
Adds fiberglass unwinding, heating, and leveling steps to the standard process, realizes one-pass continuous forming of three-layer fiber-reinforced products, with higher strength and better shrinkage performance.
Our Advantages
- High Efficiency & Low Consumption: Innovative single-screw extruder with direct-connection technology, low energy consumption, high output, long service life, maximizes production profit
- Intelligent Control: PLC control system, ABB main motor, controllable production speed, fully automated operation, and reduces labor costs
- Stable Product Quality: Advanced T-shaped molds and coat hanger-style flow channels, high-precision mirror rollers, and patented secondary stretching equipment ensure uniform substrate thickness and low scrap rate
- Multifunctional Production: One set of equipment can produce various heat-shrinkable tape and sleeve products, avoiding redundant equipment investment
- Premium Configuration: Adopts top-brand electrical components, imported high-quality adhesive raw materials (DuPont, Sumitomo, Hanwha), stable performance, low failure rate
