What Is Investment Casting?
What Is Investment Casting? Investment casting is a precision casting process used to create complex and intricate metal parts with high dimensional accuracy and fine surface finishes. This casting method is ideally suited to producing relatively high-quality components with intricate details, delicate features, and tight tolerances. Investment casting is commonly used in industries such as: […]
Quenched and tempered steel
01 Manganese steel Representative of steel 40Mn2, 50Mn2. Overheating sensitivity, high temperature tempering brittleness, water quenching is easy to crack, hardenability is higher than carbon steel. 02 Silicon manganese steel Representative steel grades 35SiMn and 42SiMn. High fatigue strength, decarburization and overheating sensitivity, and temper brittleness. It is used to manufacture gears, shafts, rotating […]
Heat treatment of steel castings
Steel castings should be used after heat treatment. Because there are casting defects such as pores, cracks, shrinkage cavities, shrinkage porosity, coarse grains, uneven structure, and residual internal stress inside the cast steel castings, the strength, especially the plasticity and toughness of the steel castings are greatly reduced. To refine the grains, uniformize the […]
What Are the Advantages of Sand Casting?
What Are the Advantages of Sand Casting? Sand casting, despite being an ancient process, offers advantages that render it highly relevant in high-technology production. Such benefits are: Low cost. Simple tooling. Easy scale-up, but great for prototyping. Fast turnaround. Few design limitations, shape complexity. Extremely wide range of materials with few/no process changes. A wide […]
Casting process characteristics of cast steel
The mechanical properties of cast steel are higher than those of cast iron, but their casting properties are worse than those of cast iron. Because the melting point of cast steel is high, the molten steel is easy to oxidize, has poor fluidity, and shrinks greatly. Its volume shrinkage is 10 to 14%, and its […]
The Process of Sand Casting
How Does Sand Casting Work? Sand casting works by generating a mold by forming a packed sand body around a wooden or rapid prototype master/pattern (or a part to be copied/reproduced). This mold requires features related to gas venting, fill and thermal compensation volumes, and core support, and it can then be filled with molten […]
Stainless steel for investment casting
Stainless acid-resistant steel is referred to as stainless steel. It is composed of stainless steel and acid-resistant steel. In short, steel that can resist atmospheric corrosion is called stainless steel, while steel that can resist corrosion by chemical media (such as acids) is called acid-resistant steel. Generally speaking, steel with a chromium content of more […]
What Is Sand Casting?
Sand casting is a commonly employed and very ancient metal casting technique. It involves forming cavities within packed and bonded sand that is then charged with molten metal. The chosen metal solidifies to reproduce the cavity shape in fine detail. The most common technique uses a pair of boxes into which is packed […]
The process of Intercooler
An intercooler is a heat exchanger that is used to cool the air that has been compressed by a turbocharger or supercharger before it enters the engine. This allows for a denser and cooler air charge to enter the engine, which can increase power and improve fuel efficiency. Intercoolers can come in various designs and […]
How To Choose Between Thread Milling and Tapping？
Selecting between thread milling and tapping depends on various factors. The decision should be based on the specific needs of your machining application. Generally, it is best to use tapping when you need to make multiple holes with little variations in size. Some key considerations to help you weigh the two options are: speed, power, […]
