The HSK 02002 is a specialized programmable logic controller (PID) that serves as the precision thermal core for HSK's industrial plastic welding systems. Unlike standard temperature controllers, it is engineered to manage the complex thermal dynamics of extrusion and hot air welding for materials like PEHD, PP, and PVC. Its primary function is to execute user-defined thermal profiles, ensuring that the heating element delivers the exact temperature required at the precise moment the material passes through, which is critical for maintaining weld integrity at high speeds.

Advanced Welding Process Control

• Multi-Step Ramp/Soak Programming: Users can create complex heating profiles, such as a controlled ramp-up to a welding temperature, a precise soak for melting, and a managed cool-down, all coordinated with the welding machine's drive system.
• Speed Synchronization: A key feature for automated welders, it actively adjusts the PID loop output based on welding speed (e.g., 0-19 m/min), guaranteeing a consistent heat input into the material regardless of production tempo.
• Material-Specific Presets: The controller stores parameter sets for different materials, allowing operators to switch between welding PEHD tank liners and PVC geomembranes with a single command, minimizing setup time.

Technical Specifications

• Selectable Inputs: Compatible with Type K thermocouples and Pt100 RTDs for versatility.
• Industrial PID Tuning: Features auto-tuning and manual PID setting with fuzzy logic enhanced control for stable thermal output.
• Dual Output Support: Provides both SSR drive and relay outputs for direct control of high-wattage heaters and external alarms.
• Robust Build: Designed for control cabinet installation with a front panel IP65 rating to withstand dusty workshop environments.

Applications

• Automatic hot air welding machines for truck tarpaulins and tents
