In forging each kind of forging, the first to calculate the material, forging in the forging of the weight and consumption for cutting. (the basic formula to calculate material G = rho V G - the proportion of rho - the weight of the blank material V - the volume of a billet) calculate way, must calculate the volume of raw materials (because of all sorts of different proportion of raw materials) and then multiplied by the proportion of the weight of the forgings, any kind of forging in the forging and closely related to the volume before and after, when forging such as pier coarse, long drawing, punching and pulling long mandrel, shoulder, moving, bending and torsion. Its overall volume remains the same, while its shape changes, such as from circle to square, from square to circle, from octagon to circle, but its volume remains the same.

Forging hammer is the most primitive method, ring forging processing equipment has forging hammer and hydraulic machine.

Different forging methods have different processes, among which the process of hot die forging is the longest

Forging manufacturers mainly by eccentric sleeve to the two bearings together, eccentric bearing is a very common bearing. Combine into a new bearing. Mainly including eccentric sleeve, outer ring, inner ring, rolling body, bearing A bearing B simple structure, easy to use, do not need other accessories to achieve the eccentric function, thus reducing the production cost of the eccentric mechanism.

Why do some MIM stainless steel products break? Potential cracks are considered to have a huge impact force and often lead to the production of complex shape parts, and for industry participants, improving the material properties gained is just a slightly higher weight solution to the crack problem.

It is well known that equipment such as hardware and tools will be corroded over a long period of time. The sources of corrosion include both man-made and natural causes. For the corrosion of different parts of stainless steel products, we take different methods. In the following content, we put forward for everyone to prevent the corrosion of stainless steel decorative products recommendations.

MIM is a process in which a plasticized mixture of a metal powder and its binder is injected into a model. The powder is first mixed with the binder, and then the mixture is pelleted and injected into the desired shape. MIM technology, as a kind of near-net forming technology for manufacturing high quality precision parts, has incomparable advantages compared with conventional powder metallurgy, machining and precision casting methods.

MIM stainless steel plates are attached to the surface and, when exposed to cold oils, must be skimmed completely, then washed with warm water and degreaser trichloroethylene, caustic soda solution, and then heat-treated. If there is a stainless steel chip on the surface, especially if the organism or gray is attached to the workpiece, the heating will definitely have an impact scale.

Cold working die steel includes die for cutting (blanking die, trimming die, punch, scissors), cold heading die and cold extrusion die, bending die and drawing die etc. Cold working die steel is the most widely used in fastener industry. It is widely used in blanking, drawing, cold heading, wire rolling and other processes. The material of the cold mold should have high hardness, strength and wear resistance, enough toughness and less heat treatment deformation.

Powder metallurgy is an industrial technique for producing metal powders or powders (or mixtures of metal powders and nonmetallic powders) as raw materials, forming and sintering them to produce metal materials, composites and various types of products. At present, powder metallurgy technology has been widely used in the fields of transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industry, and has become one of the most dynamic branches of new materials science.

The MIM mold differs from the standard plastic mold in several ways. The heat conductivity of the feed is several times higher than that of the plastic, resulting in flow The property will be much worse, and the shrinkage rate of MIM mold is usually 15% ~22%, which is much larger than that of plastic mold, resulting in the embryo

Understanding of feeding: In the MIM process, the only function of plastics is that they act as a carrier to carry gold through injection molding pressure when heated The powder is brought into the mold and cooled to form the parts we want. Usually we define plastic as the binder in the feed, its volume fraction accounts for about 40%, so the binder in the end

Most plastic products are finished after injection molding is finished, can be assembled and shipped. For the MIM, however, injection is done

Much of the growth in the MIM industry in recent years has come from cross-industry transformation and the expansion of the original MIM industry. In these

Due to the numerical control of CNC machine tools in the machining process of mechanical mold, most of the work by digital programming instead of manual operation, so relatively avoid the error of manual operation.

The first step of the MIM is the selection and preparation of materials. Once the metal powder and plastic binder are properly combined, mixed and compounded to produce an injection molding material. Using injection molding machine, the production of parts for the binder removal process. Different methods of degreasing are used depending on the type of binder used. The degreased part is then sintered to ensure the proper material composition, physical properties and correct geometry of the part.

These articles not only have high precision, but also have very good performance, and are suitable for mass production of small precision, complex metal parts, but sometimes there will be parts surface burr, which will affect the use of the beautiful, which needs to be removed by a reasonable method.
