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

Pretreatment: Sandblasting or chemical cleaning removes oxides and oil from the workpiece surface to improve coating adhesion
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
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

Parameter Category	Typical Values/Range
Processing Capacity	80,000-100,000 pieces/day (hangers)
Heating Temperature	150-300°C (plasticizing temperature)
Line Speed	0.5-2 m/min (variable frequency)
Coating Thickness	0.2-1.5 mm (depending on process requirements)
Energy Consumption	4.5-15 kW (depending on equipment size)
Line Size	Length 7-20 m (custom design)

III. Typical Application Areas

Metal Products: Surface anti-corrosion and decorative coatings for guardrails, hangers, pipes, hardware, etc.
Industrial Parts: Automotive parts, electronic components, epoxy-coated rebar, etc.
Customization: Small-batch laboratory testing or machining of custom-shaped workpieces.

IV. Core Advantages

High-Efficiency Inspection: Defect recognition rate >99%, inspection time ≤30 seconds/batch
Energy Saving and Environmental Protection: The waste powder recycling system reduces material loss, achieving an exhaust gas purification rate of over 90%
Automation Integration: PLC controls temperature, humidity, and conveying speed, supporting multi-process linkage
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

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)

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

Track Conveyor: Chain drive with gear chain and speed-controlled motor to achieve a linear speed of 0.5-2 m/min, suitable for continuous production
Hanging Rack Design: Adjustable clamps accommodate various workpieces, supporting simultaneous multi-station operation
Automated Loading/Unloading Components: 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

Drying and Curing Chamber: Double-layer structure with bottom heating and upper hot air circulation, achieving temperature control accuracy of ±5°C
Cooling and Forming Module: Water-cooled spray or air-cooled unit rapidly cools the workpiece, curing the coating and preventing deformation

IV. Auxiliary Functional Components

Circulation and Purification System: Powder recovery device reduces material loss through centrifugal filtration (≥90% recovery rate); exhaust gas treatment equipment reduces VOC emissions (≥90% purification rate)
