Multi-Axis Automotive Lamp Vacuum Coating Machine
The multiaxis automotive-lamp vacuum coating machine is a dual-door vacuum evaporation system developed for short production cycles and high stability. Coating is fully automated, with coating data monitored and recorded throughout the process. In vacuum, this fully automatic heated-filament evaporation system deposits a metal film on injection-molded PC, PBT, ABS, BMC and other parts, then directly deposits an oxide protective film described as 'SiO 2 silica-gel mold' over the metal. The automatic sequence includes low-vacuum evacuation, arc-ion-bombardment pretreatment to clean the product surface, high-vacuum evacuation (X10 -3 Pa), aluminum evaporation, and deposition of an oxidation-protection film. The latter covers the aluminum with a hardened silicon-dioxide film to prevent oxidation and peeling. The vertical vacuum chamber has two doors. Workpiece fixtures mounted on the doors can rotate individually and revolve together, with adjustable speed. A touchscreen handles setup and operation and displays the operating status. Equipment components: 1. Vacuum chamber sizes: φ1200×1400; φ1400×1500; φ1600×1600; φ1600×1800; φ1600×2000; φ1800×1800; φ1800×2000. The chamber has two doors, each accommodating fixtures with up to 8 axes, and is made of SUS304. 2. Vacuum system: mechanical pump (RP) + Roots pump (MBP) + diffusion pump (DP) + ultralow-temperature refrigeration unit reaching -140 degrees. 3. Circulating cooling-water system for vacuum-system cooling. 4. Process power supply: AC voltage regulation with thyristor voltage control. 5. Control system: programmable controller and touchscreen. 6. Production cycle: 12~15 minutes, depending on the product.
