Surface roughness refers to the small spacing and the unevenness of small peaks and valleys on the machined surface. Surface roughness is generally formed by the machining method and other factors, such as the friction between the tool and the surface of the part during machining, the plastic defor......

Steel casting refers to the parts formed after the steel is melted and poured into a specific casting mold and cooled and solidified. Steel castings usually refer to carbon steel and low alloy steel castings, which have high strength, high toughness and good weldability. Such as heat resistance, pre......

Aluminum die casting is a kind of pressure casting parts, is to use the installed pressure casting mold casting machine die casting machine, the heat of liquid poured into the aluminum or aluminum alloy die-casting machine into the mouth of the die casting machine die casting, casting the shape and ......

Surface roughness refers to the roughness of the processed surface with small spacing and small peaks and valleys. The distance (wave distance) between two wave peaks or two wave troughs is very small (less than 1mm), which belongs to the microscopic geometric shape error. The smaller the surface ro......

Lost Foam casting is, in terms of casting processes, a relatively recent innovation that exhibits characteristics of both Investment casting and Sand Casting. It is a form of evaporative pattern casting where the pattern is of foam rather than wax. The foam pattern is covered in refractory material,......

Gray cast iron is a kind of cast iron. Carbon is present in cast iron as flake graphite. The fracture is gray. Good casting, cutting performance, good wear resistance. Used for manufacturing frame, box, etc. The graphite of gray cast iron is flake, the effective bearing area is relatively small, and......
