The temperature of the standing barrel is 85-90℃. b. Standing time 6-8h. c. The stirring temperature of […]
Popular Finishes for Metal
Black Oxide Black oxide is a type of conversion coating for ferrous materials, such as steel and stainless steel, which blackens the top layer of the material. It can be used to reduce reflection and glare, as well as provide some additional corrosion resistance without affecting part dimensions. Electropolishing An electrochemical process that cleans steel […]
Wax Pattern Dressing Process
Process requirements: room temperature 24℃±3℃ operating procedure Before repairing the mold, it should be checked that the appearance of the wax mold is clear, the surface is smooth and smooth, there is no defect, the size meets the requirements, and there is no deformation. Repair mold 1. Carefully and gently scrape off the flash […]
What Is the Difference Between Iron and Steel?
The primary difference between iron and steel is that iron is a chemical element, while steel is an alloy mainly composed of iron and carbon. Iron in its pure form is soft and prone to rusting, whereas steel, with a small amount of carbon added, is harder, stronger, and less likely to rust. The addition […]
Casting and CNC machining: How to choose the right method?
The specific requirements of a part, such as its shape, size and geometry, affect the choice of manufacturing process. CNC machining and casting have advantages for different geometric shapes, so how do we decide which one to use? When determining the appropriate manufacturing method for a given part, several factors need to be considered: […]
Wax model combination (group tree)
Wax model combination Process requirements Room temperature 24℃±3℃. After welding, the minimum distance between the upper surface of the wax mold and the upper edge of the sprue cup is not less than 60mm. Wax pattern spacing after welding is 6-8mm (minimum 4mm with holes, the spacing between grooves is slightly about 10-12mm; gate length […]
What Are the Properties of Steel?
Some of the properties and characteristics associated with steel are listed below: Strength:Steel, although it varies from steel type to steel type, typically has high strength, making it an ideal material for buildings, bridges, and vehicles. Its strength can be adjusted through the addition of alloying elements and heat treatment processes. Toughness:The toughness of some […]
What Are the Different Types of Steel?
Steel comes in different types, distinguished by their composition and properties. The different steel types are mentioned and discussed below: 1. Carbon Steel Carbon steel is the most basic and widely used type of steel. It accounts for about 90% of all steel that is made. It is characterized by its composition of primarily iron […]
How to deal with rust spots on stainless steel?
1) Chemical method: Use pickling paste or spray to assist the re-passivation of the rusted part to form a chromium oxide film to restore the corrosion resistance. After pickling, to remove all contaminants and acid residues, it is very important to rinse properly with clean water. After all treatment, re-polish with polishing equipment, and seal […]
Process Flow of investment casting
Stainless steel precision casting, also known as investment casting or silica sol process, is a kind of casting process with little or no cutting. It is an excellent process technology in the casting industry. It is widely used, not only for casting various types and alloys, but also to produce castings with higher dimensional accuracy […]
