World-class leading manufacturer of Titanium Color Coating | DSP

DSP Co., Ltd. is a world top-tier color-coated metal sheet and tube manufacturer in Korea. DSP Titanium color coil is manufactured by the physical Vapor deposition method where a chunk of titanium is placed into the high vacuum to produce a perfect titanium coating. This cutting-edge ultra-functional product is widely used in many areas including automotive, electrical, and electronic industries.

What is PVD Titanium Color Coating

Physical Vapor Deposition (PVD) is a method used to deposit layers of the coating by using the condensation from the vaporized form of material and applying it to the desired target material. PVD is achieved by taking titanium Alkoxide (titanium mass) and applying a positive voltage to it while it is inside a high-temperature vacuum. This releases positively charged titanium molecules. Inside the vacuum is a material, such as stainless steel, that has a negative voltage applied to it. The negative voltage attracts the positively charge titanium molecules and results in the material being coated. Plasma cleaning and ion impact processing of materials are needed to improve the adhesion of the coating. This results in the coating having a longer lifespan. PVD technology has significantly contributed to a variety of fields including car manufacturing, electronics, and other industries.

Features and merits of DSP Titanium Color Coating

ü  Thin Film Hardness: The hardness of the product film itself was measured by the Vickers hardness test and was found to be about 10 times harder than stainless steel.

ü  Adhesion of the coating: The strength of the adhesion was tested by creating a 2mm wide scratch with a knife and attempting to peel off layers of the coating with cellophane tape. There was no peeling of the cellophane tape. coloured stainless steel manufacturer

ü  Impact Resistance: A 1kg steel ball was dropped from a height of 50cm onto the product using a DuPont impact tester. There were no abnormalities such as discoloration or damage visual observation.

ü  Abrasion Resistance: Using a SUGA abrasion tester 500g of pressure from an eraser was applied to 0.5 microns of ion plating. The applied pressure was repeated 200 times. The ion plating film was not peeled.

ü  Scratch Hardness: Load of cracking point, as seen below, was tested by scratching 150mm per minute with the Kuremence Scratch Tester. The result showed Ion coating was 3 times harder than the chemical coating on scratch-resistant hardness. decorative stainless steel supplier

ü  Artificial Sweat Test: The Ion-Coated frame was pre-soaked in artificial sweat of PH 4.5, JISLO 848 for 8 hours and left at room temperature for 16 hours.

Wet Corrosion: No damage or no color change was found on Ion coating by putting it on 50G, 98% of humidity for the duration of 500 hours.
