Vacuum Plasma Spraying

Vacuum Plasma Spraying

Vacuum plasma spraying: UV coatings are liquid paints that cure rapidly under ultraviolet (UV) light, forming a durable protective layer.
Key Advantage – Fast Curing: Under UV lamps, the coating can dry within seconds, significantly speeding up the production process.
Environmentally Friendly: UV coatings contain no volatile substances, making them safe for both the environment and application personnel.
Wide Range of Applications:They can be used on furniture, photo frames, moldings, phone cases, automotive parts, and more.

Core Information

 

1. Product Introduction

  • Vacuum plasma spraying: UV coatings are liquid paints that cure rapidly under ultraviolet (UV) light, forming a durable protective layer.
  • Key Advantage – Fast Curing: Under UV lamps, the coating can dry within seconds, significantly speeding up the production process.
  • Environmentally Friendly: UV coatings contain no volatile substances, making them safe for both the environment and application personnel.
  • Wide Range of Applications:They can be used on furniture, photo frames, moldings, phone cases, automotive parts, and more.

 

2. Core Value Proposition

  • Problem Solved: Ordinary spray coating for small or irregular-shaped parts often leaves dead corners, uneven coating, requires separate coatings for matte/high gloss, and emits strong odor.
  • Core Features: Vacuum environment spray coating ensures no dead corners; small or irregular parts achieve uniform coating; matte or high gloss selectable in a single coat; low VOC and environmentally friendly.
  • Additional Assurance: HB hardness for scratch resistance, Level 0 adhesion, curing energy 200-250 mJ/cm², suitable for mass production.

 

Core Advantages of vacuum plasma spraying

 

1. Vacuum spraying technology
  • Vacuum No-Dead-Zone Coating: In a vacuum environment, the coating uniformly wraps small or irregular-shaped parts; edges and gaps have no dead zones; coating thickness deviation ≤ 2 μm.
  • Dual Gloss Compatibility: The same formulation can achieve matte (5–7°) or high gloss (≥80°) by adjusting curing parameters, no need to change paint.
  • Low Viscosity Adaptation: Viscosity 40–45 cps (2# cup), easily atomized; coating on small parts is thin, uniform, and free of sagging.

2. Small item scenario adaptability
  • Dedicated Scenarios: Furniture fittings, decorative moldings, irregular-shaped wooden pieces, small plastic parts - "small & irregular" applications.
  • Compatible Substrates: Small wooden parts, ABS plastic, PC plastic, focusing on core small-part materials.
  • Application Advantages: Compatible with vacuum spraying equipment; integrated spraying and curing process greatly improves efficiency.

3. Flexibility and cost advantage
  • Flexible Adaptation: Dual gloss options meet different order requirements, reducing inventory costs by 50%.
  • No Dead-Zone Guarantee: Uniform coating on small/irregular parts, reducing defect rate from 10% to 1.5%.
  • Environmental Compliance: Low-VOC, solvent-free, compliant with export environmental standards for small parts.

Construction process

 

Step

Construction content

Curing energy / Key parameters

Differentiation Objectives

1

Substrate preparation

Sand small/complex parts (400 grit), clean oil and dust, blow off with compressed air

Suitable for fine-detail small parts

2

Vacuum loading

Place parts into vacuum coating equipment, seal and vacuum (≥ -0.08 MPa)

Prepares vacuum environment

3

Vacuum spraying

Atomized coating evenly covers parts, no dead corners, film thickness 15–25 μm

Ensures full coverage without dead zones

4

Leveling

Allow natural leveling inside equipment for 30 s to prevent pinholes

Optimizes coating surface smoothness

5

UV curing

Energy 200–250 mJ/cm², time 2–3 s

Fast curing, prevents part deformation

6

Post-process inspection

Check for no dead corners, no runs, gloss meets standard

Ensures quality of small/complex parts

 

Construction Precautions

 

  • Vacuum control: ≥ -0.08 MPa; otherwise, dead corners or bubbles may occur.

 

  • Film thickness control: 15–25 μm; too thick causes runs, too thin provides insufficient protection.

 

  • Storage: Store sealed at 5–35 °C; shelf life 12 months unopened, use within 30 days after opening.
