The sulfuric oxide film of stainless steel precision casting is an important factor to influence the high purity and transparency of the oxide film of stainless steel castings. The porosity, purity, thickness and sealing quality of stainless steel precision casting can directly interfere with the mi

What is the Treatment of Surface?Surface treatment is a process of forming a surface layer on the surface of the matrix material, which is different from the mechanical, physical and chemical properties of the matrix.

Cast iron can often be repaired by welding when there are some casting defects. There are many kinds of welding methods, which are mainly based on the material, size, thickness, complexity, type and size of defects, and the requirements of cutting and technical requirements.

Shell molding, also known as shell mold casting or the Corroning process, is a form of metal casting dating back to the middle of the 20th century.The metals of shell mold casting are most commonly using cast iron, carbon steel, alloy steel, stainless steel, aluminum alloys, and copper alloys. A sizable amount of the casting in the steel industry are made by shell molding process, that ensures better profitability. Typical parts manufactured in industry using the shell mold casting process include cylinder heads, gears, bushings, connecting rods, camshafts and valve bodies.

What is a steering knuckle?The steering knuckle is a component of the front suspension on a vehicle. The steering knuckle houses the wheel hub and bearing that hold to the wheel, and connects to the upper and lower control arms by way of the ball joints. The steering knuckle is also connected to the steering system (thus its name) by way of the tie rods. These components allow the wheels to spin, turn, and move up and down over bumps.

What is the benefits and advantages of Cast Irons in Engineering Applications？1.Available in a wide range of mechanical/physical properties, i.e. tensile strength from 20 KSI to over 200 KSI, hardness from 120 to about 300 Brinell in standard grades and up to about 600 Brinell in special abrasion

What is stainless steel？ Stainless steel is the abbreviation of rust resistant and acid resistant steel. It is called stainless steel with weak corrosion medium, such as air, steam and water, or stainless steel with rust, and the steel resistant to chemical corrosion medium (acid, alkali, salt and o

Hydraulic cylinders play a large role in most industries. They are used in many daily mechanical devices, including in construction equipment (engineering vehicles), manufacturing machinery, and civil engineering.The hydraulic pressure in these cylinders is in the form of hydraulic fuels that ....

Valves are usually made of metal or plastic and they have several different parts. The outer part is called the seat and it often has a solid metal outer casing and a soft inner rubber or plastic seal so the valve makes a closure that's absolutely tight. The inner part of the valve, which opens and closes, is called the body and fits into the seat when the valve is closed. There's also some form of mechanism for opening and closing the valve—either a manual lever or wheel (as in a faucet or a stop cock) or an automated mechanism (as in a car engine or steam engine).

Casting quality inspection is an important process in foundry production. Its main functions are:1. Provide quality information for casting production and management department;2. Put forward the project for the quality management activities.3. Guarantee the quality of the product. The total quality
