Gravity die casting is one of the earliest die casting processes invented by human beings. With time, it received massive improvements in respect to the equipment and the overall process efficiency.

The main reasons for expensive molds include high material costs, complex manufacturing techniques, design complexity and market demand. Mold making requires the use of special materials such as high-strength steel and wear-resistant alloys, which are more expensive.

Ductile iron can be heat treated to improve its mechanical properties, including annealing, normalising, tempering treatment and isothermal quenching. Heat treatment can change the matrix organisation, improve the plasticity, toughness and strength, applicable to different needs and shapes of castings. Reasonable heat treatment takes multiple factors into consideration and is the key to improving the performance and life of ductile iron.

Duplex Stainless Steel Casting is the casting process that takes duplex stainless steel as the raw material. It is stainless steel casting which is made from a mix of 50% to 50% austenitic and ferritic phases. So it is also called austenitic-ferritic stainless steel casting. This grade casting has a high level of strength and good corrosion resistance. Especially in sea water environment applications. At the same time, these alloys also have good toughness at lower temperatures. The higher strengths provide erosion resistance.

What is the difference between free forging and die forging, with the development of industry, the demand for forgings continues to increase, material processing, free forging and die forging is a common forging process, the application of the industry is also very wide range of fields, the requirements of the forging process is different, to create a forging performance is a big difference, do you know what is the difference between free forging and die forging?

The most significant difference between turning and milling is how the workpiece and tooling move. In turning, the workpiece rotates and the cutting tool typically does not. In milling, the cutting tool moves and rotates while the workpiece remains fixed

Casting tolerance is the accepted deviation from the desired physical dimensions of a part. It is the minimum or maximum range of measurements a product can achieve in various dimensions. Tolerances allow for slight unavoidable deviations in the dimensions of a casting. These unpreventable deviations form during the metal casting process and can result from alloy chemistry variations, furnace temperature fluctuations and different cooling rates. The more precise the part needs to be, the lower the tolerance and the closer to the desired casting dimensions. If the dimension variations are too high, it can weaken the casting, making it unfit for use.

Types of Iron Castings

Two popular methods for protecting metals from corrosion and wear are hot-dip galvanizing and electroplating. Both processes involve coating the metal with another material to create a barrier against corrosion.

Still, there are differences in how they work and their suitability for different applications. In this article, we'll look at galvanized and electroplated coatings to help you decide which is better for your industrial needs.
