LASER CUTTING
WHAT IS LASER CUTTING? Laser cutting is a thermal cutting process, in which a laser beam with high energy density is used as heating source. The process is illustrated in the paper. A laser beam is focused through a lens to a beam diameter on the surface of the work piece of approximately 0. 1 mm. […]
Salt spray test
The salt spray test is an environmental test that mainly uses the artificial simulated salt spray environmental conditions created by the salt spray test equipment to evaluate the corrosion resistance of products or metal materials. The products that need to be subjected to salt spray test are mainly some metal products, and the corrosion resistance […]
Different Types of Aluminum Casting
Different Types of Aluminum Casting All aluminum that is cast is made from aluminum and added alloy considering aluminum by itself is not very resilient. When making the decision for the type of casting method, the choice depends on the type of part as well as the strength required, its size and the quantity. Once […]
How to reduce casting defects
During the production process, foundry enterprises will inevitably encounter casting defects such as shrinkage cavities, air bubbles, and segregation, resulting in a low yield of castings, and they will face a lot of manpower and power consumption when they return to the furnace for production. How reduce casting defects is a problem that casting people […]
Pickling and passivation of stainless steel castings
What is pickling? Pickling is the method of removing scale and rust on the steel surface with an acid solution. This is one way to clean metal surfaces. It is usually performed together with pre-passivation treatment. Typically, parts are dipped in an aqueous solution such as sulfuric acid to remove oxide films on […]
The application for Aluminum alloy gravity casting
Aluminum alloy gravity casting, also known as aluminum gravity die casting, is a manufacturing process used to create high-quality aluminum alloy parts with intricate shapes and excellent mechanical properties. This casting technique is commonly used in various industries such as automotive, aerospace, electronics, and machinery manufacturing. In the automotive industry, aluminum gravity casting is […]
Causes of cracks in steel castings
In cast steel production, if casting cracks only occur near the cutting riser, the general reason is caused by low cutting temperature. Therefore, try to be as eager as possible when cutting the riser, or cut after tempering. If the process allows, by changing the riser to a smaller size, this problem can be greatly […]
Casting and melting operation process
1.Why do double phase diagrams exist? What is the practical significance of the existence of double phase diagram for the production of cast iron? What is the practical significance of the effect of silicon on the dual phase diagram? A: 1) From the thermodynamic point of view, under certain conditions, according to Fe-Fe3C phase […]
Causes and Solutions of Investment Casting defects
Porosity and shrinkage defects often occur during the production of stainless steel investment casting, whether flat ingots or round ingots. Porosity and shrinkage porosity are like twin sisters, often living together, causing a lot of trouble to process. The existence of circular holes in the stainless steel casting structure is called pores. It is a […]
Application areas of precision casting
Investment casting, also known as precision casting, is a process used to create precise dimension castings. Compared to traditional sand casting, it yields more accurate dimensions and better surface finish. Here are some application areas for investment casting: Aerospace and Aviation: Investment casting is widely used in the aerospace industry for manufacturing turbine blades, vanes, and […]
