Geetech mobile‑phone‑housing spraying line is tailor‑made for the 3C electronics industry. It integrates core processes including electrostatic dust removal, precision spraying, efficient drying and UV‑curing, forming a highly‑automated production line. The system meets strict requirements for large‑scale, high‑quality and continuous mass‑manufacturing of modern smartphone housings.
Core Features & Technical Advantages
Full‑process Automation for Maximum Efficiency
Closed‑loop fully‑automated workflow covers loading, electrostatic dust removal, spraying, flash‑off drying and UV curing to support non‑stop mass‑production. It delivers consistent spraying uniformity and stable yield rate, greatly boosting output per unit time, ideal for high‑efficiency volume manufacturing.
Precision Conveying System for Stable Operation
High‑precision bearings are applied at joints of conveyor chains and rails with high‑accuracy rail machining. The system runs smoothly without shaking, maintaining constant relative position between spray guns and workpieces, laying a solid physical foundation for high‑precision coating.
360‑degree Dead‑zone‑free Electrostatic Dust Removal
Multi‑axis adjustable electrostatic dust‑removal system supports vertical and horizontal mechanical adjustment to fit various product sizes. Combined with workpiece rotation mechanism, it thoroughly eliminates surface particles to guarantee coating adhesion and surface cleanliness from the source.
Flexible & Intelligent Spraying Control
Fixed automatic spray guns support step‑by‑step or on‑line continuous spraying modes. Spray‑gun travel and speed are digitally adjustable. Optimized motion trajectory ensures complete coating coverage on corners and curved surfaces without blind spots.
Eco‑friendly Water‑curtain Spray Booth
The water‑curtain spray booth is equipped with guide baffles to build laminar clean airflow. Paint mist is quickly captured and recycled to avoid cross‑contamination from turbulent flow. It effectively cuts VOCs emission and improves workshop working conditions.
Uniform & High‑efficiency UV Curing
Irradiation distance and angle of UV curing chamber can be freely adjusted, and lamp power is segment‑controlled according to process requirements. Built‑in rotating brackets ensure even light exposure for complex‑curved housings to realize instant curing, improving surface hardness and wear resistance.
Limitations & Challenges
High Initial Investment: As a high‑precision integrated automation system, equipment procurement, customized modification, installation and commissioning bring relatively high capital threshold. It is more suitable for manufacturers with large‑scale production capacity.
High Requirements for Operation & Maintenance: The system involves precision machinery, automatic control and UV curing technology. Higher skills are required for operators and equipment maintenance. Standardized SOP procedures shall be established for daily operation.
