The casing manufacturing process for self-service ordering kiosks integrates a series of precision industrial techniques, with the core objective of achieving a harmonious blend of rugged durability, visual appeal, and user-friendly tactile experience.
Structural Forming Process:
The main body structure typically employs high-quality SECC galvanized steel sheet. This material undergoes high-precision CNC laser cutting for blanking, followed by multiple precision bends using CNC press brakes. This process creates an internal skeleton and enclosure with high strength and rigidity. For complex curved surfaces and decorative components, injection molding is employed. Impact-resistant and weather-resistant ABS or PC+ABS engineering plastics are used, molded in a single high-temperature, high-pressure process to ensure structural integrity and dimensional accuracy.
Surface Treatment Process:
This is the critical step imparting the product’s texture and durability.
Metal Components: After pretreatment including degreasing, phosphating, and passivation, automated electrostatic powder coating is applied. Powder coatings adhere to metal surfaces via electrostatic attraction, then cure at high temperatures to form a uniformly thick, highly adhesive, scratch-resistant, and corrosion-resistant matte finish. Premium models may utilize **anodizing processes** for aluminum alloy frames to achieve superior metallic texture and abrasion resistance.
Plastic Components: Extensively utilize IMD (In-Mold Decoration) film in-mold injection molding. Decorative films printed with brand logos and operating instructions are directly embedded into the mold and molded as a single unit with the plastic. This ensures the patterns are wear-resistant and permanently affixed. An anti-UV coating is simultaneously applied to the surface to prevent discoloration from prolonged use.
