Vacuum Metallizing System
Designed for high production rate vacuum metalizing systems used in making head lamps and rear lamps for automobiles
HHV vacuum metalizing system has been designed for a cycle time of 10 minutes. Its flexibility allows coating parts made of thermoplastics (PC, ABS, ABS+PC, PC-HT, PA, PBT...), thermo sets (UP-BMC) and varnish base-coated metals (Al, Mg, SST).
This easy to use, high production rate vacuum metalizing system accomplishes effective deposition on substrates with complicated shapes and a wide range of sizes from a surface area of 50 x 50 to 200 x 900 mm and depths from 2 to 100mm. The twin door mechanism which helps to reduce the process cycle time. It has two independent gas inlet systems, one for Air / Oxygen / Nitrogen / Argon to carry-out glow discharge cleaning process and other for the monomer to carry out plasma polymerization process for pre- coat and post - coat of the reflectors. The work holder has been designed to have a carrying capacity of 100 Kg. The “Harp” design of the evaporation bus bar provides better uniform aluminum coating and penetration on to the substrate.
High production rate sputter coater
The system has been designed with a vertically mounted chamber of size 1200mm (W) x 1120mm (D) x 1800mm (Ht.) and two numbers of high power water cooled rectangular magnetron sources to hold metal target of size 160mm (W) x 1600mm (L) on either side.
The cryo refrigerator extracts the moisture condensed on the substrate which enhances the reflectivity of the reflectors. The dual pumping system helps to enhance the productivity of the equipment.
The twin door metallization system with sputtering technique enhances the value of the product, increases the productivity by reducing the cycle time with user- friendly and safety-enhanced operational processes.
A dual pumping system has been provided . A high vacuum system enables to achieve a ultimate vacuum of 10-5 m.bar. Rotary work holders of size 960mm (D) x 1600mm (Ht.), located one in each door, are made to rotate during processes. A glow discharge cleaning system has been provided for plasma pre-treatment.
Unique fearures of both the metallising System
PC - based control instrumentation enables complete automation of vacuum and evaporation cycle by using PLC and SCADA software which also acquires various data for each process cycle that can be stored and recalled. The necessary safety, alarm and control systems have been provided to ensure the safety and ease of operation.
These system have unique features of inbuilt process cycle parameters which can be selected in any order as required and they are;
- Plasma pre-treatment of substrate using the process gases (Air/Oxygen/Nitrogen/Argon) for pre - cleaning the substrate
- Plasma CVD pre-treatment of substrate using HMDSO or other monomers (TMDSO, CH4...) to facilitate good adhesion
- Plasma CVD protective coating of substrate using HMDSO or other monomers. The polymerization guarantees a protection of the substrate by preventing deterioration/ corrosion.
