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 […]
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 […]
