KIJ Excellence Titanium Sdn. Bhd., formerly known as Kristal Juta Sdn. Bhd., was founded in 1998 and was the first Physical Vapor Deposition (PVD) coating company in Malaysia.
Our PVD coating uses the vacuum deposition method which can be used to coat a range of materials, such as stainless steel, aluminium, iron, porcelain, tool steel, carbine and certain types of PVC. We use both multi arc and magnetron sputtering technology in our PVD coating process. Our facilities are able to fit products of up to 5ft in width and 20ft in height.
We are passionate and proactive in researching and developing more PVD coating colours in order to let our clients have more options to choose from. We are currently able to offer a wide range of PVD coating colours including Gold, Champagne, Nickel silver, Bronze, Copper, Brass, Black, Rose Gold, Dark Bronze (Coffee), Red Wine, Rainbow, Blue, Green, and Purple.
For the PVD Hard Coating, we are able to offer TiN, TiC TiCN, AlTiN or TiAlN, CrN, AlCrN and CrAlTiN coatings.
We currently have a team of 30 people, all of whom are highly trained and experienced. We have been appointed on many occasions to provide PVD coating services to many world famous brands and projects. Our client base is truly international and derives from a wide range of industrial sectors such as automotive manufacturers, construction companies, interior designers, shipping companies, electronic & electrical fabricators, medical companies and tools makers.
We aim to provide innovative and creative solutions for our clients, alongside an excellent quality of services.
We are proud to be your helping hands in adding value to your products.

In comparison to traditional electroplating and other existing coatings, PVD Coating has the following benefits
PVD coating means Physical Vapour Deposition of Titanium, Titanium Aluminium and Chromium. The process is also referred to as Titanium/Titanium Aluminium/ Chromiumplating. The technology behind PVD coating is based upon the principle of plasma acceleration. The method involves purely physical processes, such as low temperature vacuum evaporation with plasma sputter bombardment.
PVD coating is one of the best methods for enhancing thin film plating elements. The vacuum deposition method coats the product with a film of hard refractory material 1-2 microns thick.
The picture above is the result of a 3000 times x-ray taken of a 1mm stainless steel plate after coating. The result shows that the 1mm coated stainless steel plate contains of 3% of the PVD coating and 97% of original stainless steel.
PVD coating is takes place in vacuum chamber by evaporation process. Titanium/ Titanium Aluminium/ Chromium is vaporised by means of multi arc or magnetron sputtering. The positively charged Titanium/Titanium Aluminium/Chromium ions are mixed with nitrogen or argon gas to form a plasma. The positively charged Titanium/Titanium Aluminium/Chromium plasma is attracted to the negatively charged workpiece, thereby forming a coating on the workpiece.
We are currently able to offer 2 kinds of PVD coating technologies:
1. Multi Arc technology
2. Magnetron sputtering technology
Magnetron sputtering technology is somewhat different from the multi arc technology. The difference is that magnetron sputtering technology uses magnetic fields to keep the plasma in front of the workpiece, intensifying the bombardment of ions. As a result, the magnetron sputtering coating has a molecular structure a few times smaller than that of the multi arc coating. The deposition is slower, thereby creating a surface layer with much higher density and greater compaction.
The PVD coating exhibits unprecedented toughness, lubricity, uniformity, and is chemically more stable in comparison to the traditional ion plating method.
PVD Coating can be used on various materials, such as stainless steel, aluminium, iron, porcelain and certain types of PVC.
Stainless steel is best recommended for PVD Coating. Stainless steel will fade and oxidise over time when exposed to the environment, humidity, and other factors. However, stainless steel that has been PVD coated:
The SIRIM test results for the PVD Coated Stainless steel are outlined below:
The SIRIM test result via Energy Dispersive X-Ray Analysis (EDX) also showed that the composition of the coated material on the surface of the plate contained titanium of 97.8% and Nitrogen of 2.2% (TiNx).
The finish of PVD Coating will depend upon the surface of the product being coated, for example long grain/hairline, etched, textured and mirror. Any engravings, patterns or designs which are apparent on the surface of the product will not be diminished through the PVD coating process. Even hairline markings will be clearly visible after the application of the coating.
The colour of the coating can be varied. The colours currently available for PVD coating are: Gold, Champagne, Nickel silver, Bronze, Copper, Brass, Black, Rose gold, Dark Bronze (Coffee), Red Wine, Rainbow, Blue, Green and Purple We are continuously researching and developing the process to add more colours. If there is a particular colour that you are interested in developing, please do not hesitate to contact us.
PVD hard coating uses a similar vacuum deposition coating method as the standard PVD coating. Both multi arc and magnetron sputtering coating technologies can be used for the PVD hard coating. The differences between PVD hard coating and the standard PVD coating are:
Titanium hard coating can be used on certain materials, such as tool steel, carbine and stainless steel.
For the hard coating, we are currently able to provide: Titanium Nitride (TiN), Titanium Carbide (TiC), Titanium Carbo-Nitride (TiCN), Aluminium Titanium Nitride (AlTiN) or Titanium Aluminium Nitride (TiAlN), Chromium Nitride(CrN), Aluminium Chromium Nitride (AlCrN) and Chromium Aluminium Titanium Nitride (CrAlTiN) coating.
