Tempering
Tempering is a heat treatment process in which a quenched metal product or part is heated to a certain temperature, and after a certain period, it is cooled in a certain way. Process, so the combined process of quenching and tempering is called final treatment. The main purposes of quenching and tempering are: 1) […]
Forging
Forging Like metal casting, forging has been used for centuries. It is the process of heating and shaping metal parts by force. The familiar image of a blacksmith and anvil comes to mind. Today, forging is widely used in automated industrial processes. How It Works Modern forging uses high-impact machines to shape metals into desirable […]
Quenching
What is quenching? The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypo-eutectoid steel) or Ac1 (hypereutectoid steel), keep it for a while, make it fully or partially austenitized, and then cool it at a temperature greater than the critical cooling rate. The heat treatment process […]
The characteristics of Aluminum alloy castings
Aluminum alloy castings possess several distinctive characteristics: Lightweight: Aluminum alloys are known for their low density, making them significantly lighter than many other metals. This feature is advantageous for applications where weight reduction is essential, such as in automotive and aerospace industries. Good corrosion resistance: Aluminum alloys exhibit excellent resistance to corrosion, particularly when properly […]
Causes of machining errors
Machining error refers to the degree of deviation between the actual geometric parameters (geometric size, geometric shape, and mutual position) of the part after machining and the ideal geometric parameters. The degree of agreement between the actual geometric parameters and the ideal geometric parameters after the part is machined is the machining accuracy. The smaller […]
SURFACE TREATMENT SERVICES OF METAL
What Is Surface Treatment? Surface treatment is a process of artificially forming a surface layer on the surface of the base material that is different from the mechanical, physical, and chemical properties of the base body. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special […]
Magnetic particle testing
Magnetic particle inspection is suitable for detecting surface defects and defects several millimeters deep below the surface. It requires DC (or AC) magnetization equipment and magnetic powder (or magnetic suspension) for inspection operations. Magnetizing equipment is used to generate a magnetic field on the inner and outer surfaces of the casting, and magnetic powder or […]
Heat treatment quality inspection
Heat treatment is an important link in machinery manufacturing. The quality of heat treatment is directly related to the inherent quality and performance of products or parts. Many factors affect the quality of heat treatment in production. To ensure that the product quality meets the requirements of national standards or industry standards, all heat treatment […]
Surface Treatments

Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on the surface of certain metals. Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.), and enhance aesthetics. Electroplating is further divided into specific processes such as copper plating, gold […]
Wax mold defects
Due to various reasons, the wax mold produced by the wax pressing machine will have some defects, mainly including the following: full of dissatisfaction The main reason is that the temperature of the wax material is low, the injection speed is slow, and the pressing temperature is low, which causes the wax material to […]
