Product Description
Spray Processing Treatment
Industrial-Grade Surface Coating Solution for Various Materials
Spray Processing Treatment is an advanced surface finishing technology that involves spraying a coating material onto the surface of components such as plastics, metals, or composites using high-pressure spray systems. This process creates a uniform, well-adhered film that enhances both functionality and appearance. It improves durability, visual appeal, and can add specific properties such as scratch resistance or surface gloss.
Designed to meet the needs of industries such as automotive, electronics, appliances, and premium packaging, Spray Processing Treatment is a key step in enhancing product value and overall quality.
Functional Features
1. Air Spray (Conventional Spray)
Description: Uses compressed air to atomize and spray the coating onto the surface.
Advantages: Fine atomization, good for smooth finishes.
Applications: Decorative coatings, glossy finishes, consumer electronics.
2. Airless Spray
Description: Forces coating material through a high-pressure nozzle without air, creating a fan-shaped spray pattern.
Advantages: High transfer efficiency, ideal for thicker coatings.
Applications: Industrial machinery, automotive parts, heavy-duty protection.
3. Electrostatic Spray
Description: Applies an electric charge to the paint particles, which are attracted to the grounded workpiece.
Advantages: High coverage efficiency, reduced overspray.
Applications: Automotive body panels, plastic casings, appliance surfaces.
4. HVLP (High Volume Low Pressure)
Description: Delivers a high volume of air at low pressure for fine atomization with minimal overspray.
Advantages: Precise control, better finish quality, eco-friendly.
Applications: High-end consumer products, cosmetic packaging, custom parts.
5. Robotic or Automated Spray Systems
Description: Uses programmable robotic arms to perform consistent, repeatable spray patterns.
Advantages: High consistency, efficient for large-scale production.
Applications: Mass production lines in automotive, electronics, and home appliances.

Application
Paint or Primer Application for Finishing
In some CNC workflows, spray systems apply primers, paints, or other finishes directly to the machined part. This prepares components for final assembly or enhances aesthetics and corrosion resistance.

FAQ
| Question | Answer |
| When is spray processing used | It is used during or after machining, such as to reduce heat (during milling or turning) or to coat/clean parts after machining is completed. |
| How is it different from traditional coolant methods | Spray processing, such as MQL, uses minimal amounts of lubricant but is highly effective, producing less waste and is more suitable for high-precision work than traditional coolant methods. |
| Can it be used with all materials | Yes, it can be used with most materials, such as metals (steel, aluminum), plastics, and even ceramics, depending on the type of spray and the material being sprayed. |
| Does it require specialized equipment | Yes, specialized equipment is needed, such as spray nozzles, pressure control systems, storage tanks for lubricants, or thermal spray guns, depending on the type of spraying used. |
| Does surface coating affect the accuracy of the part | If not controlled properly, it can affect the part's size or surface. However, when using precise techniques like plasma spray or HVOF, the impact is minimal and can be controlled effectively. |
