For car lighting PVD coating solutions, the coating process had experienced a change from complicated process till the advanced technique.
HMDSO Coating Technologies on each steps:
1) Plasma Ionization Pre-treatment -- glow discharging, standard gas is Argon and N2 is for optional.
2) PECVD reaction -- HMDSO base coating to enhance the adhesion between substrate and Aluminum layer.
3) Aluminum thermal evaporation
4) PECVD reaction -- HMDSO top coating
3. Steps 1, 2 & 3 are regarded as essential pre-treatment before PVD coating, also is a guarantee of a high quality coatings.
4. 1) If lights are produced with high class moulds, and no need primer coating, lights can be put into the Vacuum Metallizer directly,
the coating processes: HMDSO---> Aluminum Metallizing---> HMDSO
2) If the lights surface are not smooth, the primer coating is required, so following the step 4 and 5,
the coating process: Aluminum Metallizing--->HMDSO
Advantages
A: 2-door structure machine for a fast loading/unloading, high yield;
B: Robust structure design;
C: High vacuum pumping speed configurations;
D: Simens PLC + SiemensTouch Screen Operation System, fully automatically /Manually control;
E: Easy access to the working environment for maintenance work;
F: The unique rotary rack and evaporation system to guarantee a high uniformity.
----- The height from substrate to evaporation source can be adjusted flexibly ;
----- Evaporation sources distance can be adjusted;
------Bombardment device for strong adhesion (your machine might not require this unit)
G: HMDSO module to do TOP protective layer. The PVD metallization and HMDSO (PECVD process ) completed in PVD machine chamber, avoid the contamination, which reduce the production cost and improve high yield.
ONE TOUCH OPERATION, HIGH PRODUCTIVITY, HIGH YIELD, ENERGY SAVING.
