Product Description

Oven Enamel Production Line: Comprising a fully automatic pre-treatment system, wet automatic enamel spraying/dry electrostatic automatic enamel spraying modules, wet enamel drying, high-temperature firing, cooling, and inspection units. Complete lines or individual modules can be customized to meet specific requirements.

Applicable Workpieces

Categories: Oven liners (rectangular and curved), oven door glass frames, grill racks (wire mesh), and oven outer casing panels.
Materials: Cold-rolled carbon steel and Stainless Steel (grade 304).
Specifications: Compatible dimensions from 300mm x 200mm x 100mm to 1200mm x 600mm x 400mm.

Key Advantages

Specialized Coating for Complex Shapes

For complex structures such as rounded corners of oven liners and gaps in grill rack mesh, a dual-mode coating module is utilized. This includes electrostatic coating for flat parts and servo-driven roller coating for curved parts. Component qualification rate consistently exceeds 99.6%.

Energy Efficiency & Waste Heat Recovery

Equipped with a flue gas waste heat recovery heat exchanger achieving a utilization rate of ≥72%. The system reduces heat loss by 40% compared to traditional equipment, significantly lowering operating costs and supporting green production.

Full Process Automation

From loading to inspection, the entire process is automated. Only two personnel are required for material feeding and handling, reducing labor costs by up to 85% compared to manual lines. Supports "one-touch switching" for different models in ≤3 minutes.
