Customizable Industrial Parts Automatic Immersion Coating Line for Customization Needs

Equipment Description:

I. Process Flow
Workpiece Loading → Pretreatment (Degreasing, Cleaning) → Preheating → Dipping → Plasticizing and Curing → Cooling → Inspection → Unloading
1. Pretreatment: Sandblasting or chemical cleaning removes oxides and oil from the workpiece surface to improve coating adhesion;
2. Dipping: The workpiece is immersed in a fluidized bed of powder. Coating thickness is controlled by the immersion time (10-60 seconds) and the degree of powder fluidization;
3. Inspection: An integrated conductive medium detection box detects defects such as pinholes and bubbles through resistance changes, triggering an audible and visual alarm.

II. Key Parameters and Technical Specifications

III. Typical Application Areas

1. Metal Products: Surface anti-corrosion and decorative coatings for guardrails, hangers, pipes, hardware, etc.
2. Industrial Parts: Automotive parts, electronic components, epoxy-coated rebar, etc.
3. Customization: Small-batch laboratory testing or machining of custom-shaped workpieces.
IV. Core Advantages
1. High-Efficiency Inspection: Defect recognition rate >99%, inspection time ≤30 seconds/batch;
2. Energy Saving and Environmental Protection: The waste powder recycling system reduces material loss, achieving an exhaust gas purification rate of over 90%;
3. Automation Integration: PLC controls temperature, humidity, and conveying speed, supporting multi-process linkage;
4. Flexible Adaptability: The modular design enables rapid changeovers and is compatible with different coating types (e.g., PVC and epoxy).

Main structures and components

I. Core Processing Units
1. Dipping Machine
Fluidized Bed Structure: A porous air plate at the bottom allows compressed air to uniformly fluidize the powder coating, ensuring consistent coating on the workpiece.
Heating System: A built-in anthracite furnace or electric heating tube supports a temperature range of 150-300°C, suitable for melt adhesion of materials such as PVC and epoxy resin.
Lifting Mechanism: Controls the depth and duration of workpiece immersion in the powder, allowing precise adjustment of coating thickness (0.2-1.5mm).
2. Pretreatment Module
Cleaning Tank: Uses spraying or immersion to remove oil and oxides from the workpiece surface, improving coating adhesion.
Pickling/Phosphating Tank: Chemically treats metal parts to enhance corrosion resistance.

II. Conveying and Drive System
‌1. Track Conveyor
‌Chain Drive: A gear chain and speed-controlled motor combine to achieve a linear speed of 0.5-2 m/min, suitable for continuous production.
‌Hanging Rack Design: Adjustable clamps accommodate various workpieces, such as guardrails and hangers, supporting simultaneous multi-station operation.
‌2. Automated Loading/Unloading Components: A robotic arm or vibrating plate automatically loads workpieces, increasing efficiency to 80,000-100,000 pieces per working day.

‌III. Temperature Control and Curing Unit
‌1. Drying and Curing Chamber
‌Double-layer structure: The bottom layer is heated (using an anthracite furnace or electric heating tubes), while the upper layer circulates hot air for even distribution, achieving a temperature control accuracy of ±5°C.
‌Dimensions: Common lengths range from 7-20 m, with a height of 2 m, suitable for extended production lines.
‌2. Cooling and Forming Module: A water-cooled spray or air-cooled unit rapidly cools the workpiece, curing the coating and preventing deformation.

IV. Auxiliary Functional Components
1. Circulation and Purification System
Powder Recovery Device: Reduces material loss through centrifugal filtration, achieving a waste powder recovery rate of ≥90%;
Exhaust Gas Treatment Equipment: Catalytic combustion reduces VOC emissions, achieving a purification rate of ≥90%.
2. Detection and Monitoring Module
Conductive Medium Detection Box: Identifies coating pinholes and bubbles through resistance changes, triggering an alarm;
Temperature Control Instrument: PID temperature control with integrated fault alarm function.

V. Control and Energy System
1. Control Center
PLC controls conveying speed and temperature parameters, supporting multi-process linkage;
Inverter adjusts motor speed, enabling forward and reverse switching.
2. Energy Module: Power is provided by a motor and gearbox, with optional manual speed or variable frequency motor options.
The power supply is compatible with 50-200A DC power to meet heating and drive requirements.
