Magnetron Sputtering Coating

Plasma coating 
Magnetron sputtering is a plasma coating process whereby sputtering material is ejected due to bombardment of ions to the target surface. The vacuum chamber of the PVD coating machine is filled with an inert gas, such as argon. By applying a high voltage, a glow discharge is created, resulting in acceleration of ions to the target surface and a plasma coating. The argon-ions will eject sputtering materials from the target surface (sputtering), resulting in a sputtered coating layer on the products in front of the target.  Magnetron sputtering technology is characterized by:

• A water-cooled target, so little radiation heat is generated
• Almost any metallic target material can be sputtered without decomposition
• Non-conductive materials can be sputtered by using radio frequency (RF) 
  or medium frequency (MF) power
• Oxide coatings can be sputtered (reactive sputtering)
• Excellent layer uniformity
• Very smooth sputtered coatings (no droplets)
• Cathodes (of up to 2 meter long) can be put in any position, therefore high 
  flexibility of sputtering equipment design

-High realibility

-High productivity and flexibility

-Consistently brilliant end product quality

-Full automation capability

-Excellent coating flexibility

-Long lifetime and fast target exchange

-Flexible system configuration

-High speed coating and best PVD homogeneity

HCVAC decorative PVD films are routinely used as a replacement for electroplated chrome.  They can be applied directly over almost any substrate material and can be deposited in a wide variety of colors. The process parameters to deposit each color are stored in software recipes with different process steps. Once the coating process has started, all of the relevant process parameters are continuously monitored and controlled by the on-board computer software.

It can be used to coat metal film, titanium nitride, titanium carbide, and zirconium nitride, chromium nitride and titanium, nickel, chromium, copper , and other compounds film, multi-layer super-hard film, nitrogen-doped titanium film and the alloy film, and in a very short time to complete all the machining process, it is a highly efficient multi-functional coating equipment.

This machine is extensively used in the fields of ultra-hard coating for the tools and mould, decorative coating for watch, jewelries, stainless steel tableware, golf head, hotel product, sanitary ware, luminaires, optical frame, hardware, etc .

HCVAC can help you to enter the PVD coating easily by our vacuum coating machine and full range service. We will provide with most suitable technology according to your requirements.

   We will make the special coating solution for each customer; combine the full set production technics to meet your requirements, to ensure high efficiency of production.

Easy to implement

  To many people unfamiliar with the process, PVD coating technology seems complicated. However, with the right investments and a good support, it is easier than expected. HCVAC has developed a turnkey coating process that makes a PVD coating centre easy to implement. A complete coating process consists of several steps: stripping (depending on the part’s history); pre-treatment; quality control; cleaning & drying; fixturing & visual inspection; PVD coating; quality control & thickness measurement and post-treatment (depending on the application). These steps are all available from one partner: HCVAC Technology, including mature technics and coatings.
