PVD technology has been widely used in various parts of vehicles manufacturing process, please review below image and learn what Royal Tec can provides you:

HMDSO (Hexamethyldisiloxane) coating is a type of thin film coating that is commonly used in various applications due to its unique properties. HMDSO is a precursor molecule that can be used in processes like Plasma-Enhanced Chemical Vapor Deposition (PECVD) to deposit thin films onto substrates.

Here are some key points about HMDSO coating:

Hydrophobic Properties: HMDSO coatings are known for their hydrophobic nature, meaning they repel water and other polar substances. This property makes HMDSO coatings useful in applications where water resistance is important

Dielectric Properties: HMDSO coatings can have good dielectric properties, making them suitable for insulating applications in electronics and other industries. 

Biocompatibility: HMDSO coatings can be biocompatible, making them suitable for applications in medical devices and implants.

Optical Transparency: Depending on the deposition process and parameters, HMDSO coatings can be optically transparent, which is useful in applications where transparency is required.

Chemical Resistance: HMDSO coatings can offer good chemical resistance, protecting the underlying substrate from corrosion or chemical attack.

Adhesion Promotion: HMDSO coatings can improve the adhesion of subsequent layers or coatings on a substrate, enhancing the overall durability of the coating system.

Tribological Properties: HMDSO coatings can provide good wear resistance and lubricity, making them suitable for applications where low friction and wear are important.

Barrier Properties: HMDSO coatings can act as barriers against moisture, gases, and other environmental factors, protecting the substrate from degradation.

HMDSO coatings are versatile and find applications in various industries, including electronics, optics, aerospace, automotive, and biomedical fields. The properties of HMDSO coatings can be tailored by adjusting the deposition parameters and processes to meet specific application requirements.

1. Vacuum Metalizing( & Sputtering System) Equipment

A: Automotive Lighting Reflectors

B: Exterior & Interior Trims, handles

C: Automotive LOGO LED board

D: Bezels and bumpers

2. The substrate materials:

• BMC part
• PC+ABS, ABS

2.3. Aluminum alloy

• For car lighting PVD coating, there are 2 techniques: DC magnetron sputtering and Resistance Thermal evaporation. Our standardized machine models:

RTEP1600-HMDSO, chamber inner size (diameter*H mm ) 1600*1980

RTEP1800-HMDSO, chamber inner size (diameter*H mm ) 1800*1980

RTSP1420-HMDSO,chamber inner size (diameter*H mm ) 1420*1980

RTSP1420-HMDSO, is for fast cycle demand (10 mins per cycle) which connect with Plastic Injection machine, after injection the parts go to PVD chamber directly for PVD+ HMDSO top coating.

RTEP1600-HMDSO, & RTEP1800-HMDSO, are thermal evaporation coating machines, which contains 6 or 8 planetary rods, depends on the max. Size of substrates. Cycle time 15~18 mins.

Advantages

A: 2-door structure machine for a fast loading/unloading, high yield;

B: Robust structure design;
C: High vacuum pumping speed configurations;

D: PLC + Touch 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.
