Core Product Value

The Trolley/Batch-Type Hot Air Circulation Oven focuses on the Copper Foil Antioxidant Drying scenario. With three core advantages—Precise Temperature Control, Batch Processing, and High Cost-Effectiveness—it addresses the pain points of "uneven drying, low efficiency, and high costs" in copper foil production:

  • Precise Temperature Control (±1℃): Adopts PID intelligent temperature control algorithm to ensure stable temperature within the 100-150℃ drying range. This enables uniform curing of the antioxidant, effectively improving the consistency of copper foil surface protection performance and reducing product defect rates caused by temperature fluctuations.
  • Efficient Batch Processing: The trolley/batch-type loading design supports simultaneous processing of multiple copper foil rolls. Combined with a high-airflow hot air circulation system, the single-batch processing capacity is increased by over 30% compared to traditional equipment, significantly improving the throughput of the drying link in the production line.
  • High Cost-Effectiveness: Optimizes the equipment structure while ensuring core performance. The cost is 40% lower than imported equipment, and energy consumption is reduced by 15-20%. It provides copper foil enterprises of medium and large scales with a drying solution that "delivers good results at a reasonable investment."

Application Scenarios & Processes

Core Process for Copper Foil Antioxidant Drying

After coating the copper foil surface with an antioxidant, it needs to be dried and cured within the 100-150℃ range to remove solvents and form a stable protective layer. The trolley-type oven ensures this process is efficient and uniform through "precise temperature control + hot air circulation":

Typical Process Curve

  1. 1 Preheating Stage: Room Temp → 80℃, heating rate of 3℃/min, 20min heat preservation (initial solvent evaporation)
  2. 2 Drying Stage: 80℃ → 120℃, heating rate of 2℃/min, 60min heat preservation (main antioxidant drying)
  3. 3 Curing Stage: 120℃ → 140℃, heating rate of 1℃/min, 40min heat preservation (antioxidant layer curing)
  4. 4 Cooling Stage: 140℃ → 60℃, natural cooling (avoids thermal shock)

The equipment's intelligent temperature control system can accurately replicate the above curve. Through "slow heating + long heat preservation," it ensures the antioxidant forms a uniform film on the copper foil surface, providing a stable base material for subsequent workpiece lamination processes.

Extended Application Scenarios
