Product Description

Integrated Automated Enamel System

The Oven Enamel Production Line comprises a fully automatic pre-treatment system, wet automatic enamel spraying or dry electrostatic automatic enamel spraying modules, drying units, high-temperature firing, cooling, and inspection units. This line is specifically designed for oven cavities, oven doors, cooktop panels, and grill racks.

Applicable Workpieces

Categories: Oven liners (rectangular and curved), door glass frames, grill racks, and outer casing panels.
Materials: Cold-rolled carbon steel and high-end Stainless Steel (Grade 304).
Compatibility: Accommodates dimensions from 300x200x100mm up to 1200x600x400mm.

Key Technical Advantages

Specialized Coating Solutions

For complex structures like oven liner corners and grill mesh, the dual-mode coating module uses electrostatic coating for flat parts and servo-driven roller coating for curved parts. Narrow-aperture nozzles (1.2-1.5mm) ensure precision, achieving a qualification rate exceeding 99.6%.

Multi-Zone Temperature Control

The firing furnace features multi-zone control to meet differential temperature requirements. PLC-regulated dwell times and heating layouts ensure uniformity within ±5℃, preventing discoloration from over-firing.

Energy Efficiency

Utilizes composite insulation (1260℃ refractory brick and aluminum silicate fiber) reducing heat loss by 40%. Equipped with flue gas waste heat recovery achieving ≥72% utilization.

Product Functions

Full Process Automation: Achieves unmanned operation through degreasing, pre-treatment, drying, coating, firing, and inspection phases.

Multi-Component Compatibility: Dual-mode design adapts to various shapes. Supports storage for over 10 oven models with one-touch switching.

Precision Parameter Control: PLC monitoring of flow rates, temperature, and concentration. Automatically adjusts speed based on workpiece curvature.

Quality Traceability: QR code and FRD system documents process data for over a year, facilitating data export and quality audits.

Product Features

Appliance-Specific Design: Customized firing curves for liners to strengthen enamel adhesion under high-temperature usage conditions.

Modular & Expandable: Functional modules can be independently combined. Expansion from household to commercial demand requires only parameter adjustments.

Easy Operation: Graphical touch screen interface allows new operators to work independently after 2 hours of training.

Intelligent Monitoring: Real-time display of conveyor speed and furnace pressure. Abnormal situations trigger audible and visual alarms.

System Composition

Pre-treatment Module

Includes degreasing (50-55°C), 2-stage rinsing with online water quality monitors, and a hot air circulation drying tunnel (90-200°C) lined with SUS304 stainless steel.

Enameling Module

Features 2 servo-driven roller coating machines for irregular parts and electrostatic machines for flat parts (60-80kV). Repeat positioning accuracy is within ±0.05mm.

Firing/Curing Module

Continuous gas radiant tube or electric furnace. Includes a cold-hot workpiece exchange zone (280-350°C) and a primary firing zone (750-850°C).

Industry Capability

As a national high-tech enterprise and vice chairman unit of the Enamel Industry Association, the manufacturer possesses over 90 utility model patents and 30+ invention patents. The manufacturing base spans significant area, equipped with advanced processing technologies for high-end enamel equipment.

Frequently Asked Questions

1. What is the standard production lead time for the equipment?

The standard production cycle for a complete coating line is between 30 to 70 days. This depends on customization requirements and specific functional modules.

2. What information is required for a procurement quote?

Please provide the workpiece type, maximum dimensions (LxWxH), weight range, expected daily output, preferred coating process (powder, liquid, or enamel), and available factory space dimensions.

3. How is the installation and commissioning handled?

We provide turnkey installation. Engineers will go to your factory to install and test the equipment. The process typically takes 30-60 days depending on the project complexity.

4. What kind of after-sales support do you provide?

We offer a 12-month warranty, remote technical debugging within 2 hours of a request, and a supply of wearing parts (filters, nozzles) delivered within 3-7 working days.

5. Does the equipment comply with food safety standards?

Yes, the finished products undergo food contact safety tests in compliance with GB 4806.10-2016, ensuring they meet safety requirements for high-temperature oven use.

6. How user-friendly is the system for new operators?

The system features a graphical PLC touch screen with pre-set templates. Most operators can work independently after just 2 hours of training.
