Intelligent PLC Control

Our electrical control system adopts a PLC and touch screen control method, utilizing world-renowned electrical brands. By integrating expertise from both the electrical and rubber processing fields for software optimization, we have developed a unique rubber production control system where stability and intelligence are our utmost pursuits.

The temperature control system employs solid-state controllers with a precision of ±1°C, significantly ensuring the quality of rubber vulcanization.

Precision Vulcanization Control

Dynamic Adjustment
Real-time proportional pressure/flow adjustment during stages (mold closing, holding, demolding) ensures optimal curing.

Process Consistency
Uniform mold pressure via proportional valves prevents defects (under-cure/flash). Programmable curves guarantee batch-to-batch precision for automotive/industrial tolerances.

Adaptive Integration
Multi-recipe presets for compound/geometry changes. PLC/HMI compatibility enables centralized monitoring and automation.

Nitrided Hot Plates Enhance Vulcanizing Press Performance

  • Nitriding creates 0.2-0.5mm hardened layers (1,000-1,200 HV) for exceptional wear resistance against abrasive rubber compounds and pressure cycles.
  • Sustained flatness ensures consistent heat transfer, extending service life by resisting scratches and oxidation at 150-200°C.
  • Oxidation-resistant surfaces maintain ±1°C thermal stability, critical for precision vulcanization in automotive/industrial applications.

Vacuum Pumps in Vulcanizing Presses: Key Benefits

  1. Eliminate Air Defects: Remove trapped air, moisture, and volatiles during vulcanization to prevent blisters, porosity, and incomplete curing.

  2. Boost Product Integrity: Ensure uniform material density for airtight seals, gaskets, and vibration dampers.

  3. Enhance Process Precision: Achieve defect-free rubber components critical for automotive/industrial applications.

Automated Mold Opening System: Core Advantages

  • 70% Faster Cycles: Auto-handling completes in <10s (vs. manual 30s), boosting throughput.
  • Labor-Saving Operation: Reduces reliance on skilled workers, ideal for labor-scarce regions.
  • Smart Maintenance: Self-lubrication extends component lifespan (guide rails/bearings).
  • PLC/HMI Control: Customizable parameters (speed/sequence) via touchscreen.

  • Double powers, double oil pumps, double motors and double oil coolers are applied for the two axles to work independently.
  • The oil system is unique in design, with good stability, faster lift-up and lift-down speed compared with other brands during unloading/loading mold.
  • High vacuum and the average pumping method are applied for the manufacture of stable products and improving the quality and productivity.
  • The pedestal vacuum oxygen tank provides large oxygen storage space.
  • The new mold raising mechanism design has the advantages of long working life,quiet mold-uploading/loading, fastness and stability.
  • This is suitable for the highly precise products such as Melamine,rollers, shoes, medical drug plugs, automobile parts, shake-proof products, gaskets, conductive products and electronic equipment.
