Electropolishing process for steel materialsDue to the many types of steel materials, the composition varies greatly, different steel should be selected through the test polishing solution formula and operating conditions to obtain the best results. Read More

Polishing is a processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of a workpiece in order to obtain a bright, flat surface. Read More

In the process of industrial products to diversify, high-grade development, how to improve the quality of moulds directly affect the quality of products is an important task. Read More

Grinding and polishing are different treatmentsGrinding processing refers to the use of abrasive particles coated or embedded in the research tool, through the relative movement of the research tool and the workpiece under a certain pressure on the processing surface for finishing processing.

PVD (Physical VaporDeposition) is a technique for depositing thin films with a particular function on the surface of a substrate by physically vaporising the surface of the material source into atoms, molecules or ions under vacuum conditions. Read More

Sandblasting is the use of compressed air as the power to form a high-speed jet beam, the abrasive high-speed jet to the surface of the workpiece to be treated, so that the external surface of the workpiece physical changes to meet the quality requirements. Read More

Mirror polishing is a polishing process that gives a mirror effect to the surface of a product. The process is commonly used for lift cabins, aerospace equipment parts, moulds, automotive parts, medical machinery, decorative items, etc. Such products require a glossy appearance. The surface after polishing treatment is scarless, bright, smooth, no relief, no metal disturbance layer, no crater like mirror surface state, is the ideal mirror polishing effect. Read More

Metallographic specimens need to be polished after grinding, in order to remove the abrasion marks and deformation layer produced by the grinding process on the specimen, so that it becomes a smooth mirror surface. The current methods of polishing specimens are mechanical polishing, electrolytic polishing, chemical polishing and compound polishing. The most commonly used polishing method is mechanical polishing. Read More

Surface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosiSurface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosion resistance, wear resistance, decoration or other special functions. The following are common surface treatments.on resistance, wear resistan Read More

PVD coating is a common tool coating used in industrial production and has been developed for a long time, and is widely used in cutting tools, tooling and other finishing industries. However, as the level of industrial production increases, the requirements for tool coatings are becoming higher and higher. Although the preparation methods are progressing, it is inevitable that there will still be some shortcomings in the preparation process. Read More

PVD coatings are currently available in dark gold, light gold, coffee, bronze, grey, black, grey-black and seven colours. The colour of the coating can be controlled by controlling the relevant parameters during the coating process; the colour can be quantified by measuring the colour with relevant instruments after the coating is completed to determine whether the colour produced meets the requirements.

Vacuum coaters are becoming more and more widely used, but do you know how to maintain them? Read More

The specific principle of PVD (ion coating) technology is the use of low voltage, high current arc discharge technology under vacuum conditions, the use of gas discharge to evaporate the target material and make the evaporated material and gas are ionised, the use of electric field acceleration, so that the evaporated material and its reaction products deposited on the workpiece. Read More

The production conditions of die casting moulds are the most demanding, with metal solutions at high temperatures of 600-800°C, injection through high pressures and constant thermal expansion and contraction of the mould surface, resulting in a very short service life for die casting moulds, which constantly require mould repair and maintenance during production. The main causes of die casting mould failure are cracking, erosion, sticky material and deformation. Read More

Vacuum coating is a physical vapor deposition process (PVD) in which a metal or metal compound is deposited onto the surface of a material (usually a non-metallic material) in the form of a vapor phase under a vacuum environment. It is also called vacuum metallization because the coating is often a thin metal film. Vacuum coating in a broader sense also includes the vacuum vapor deposition of non-metallic functional films such as polymers on the surface of metallic or non-metallic materials. Read More
