Defects in forgings caused by defects in raw materials

The raw materials used in forging are ingot casting, rolling, extruding and forging blank. Rolled, extruded and forged billets are semi-finished products of ingot through rolling, extrusion and forging respectively.

To determine the use of CNC handboard model processing mode, it is necessary to determine the installation of the handboard base, processing base, processing margin, let CNC processing technology advantages get full play.

The preparation of raw materials for the MIM process is usually a mixture of metal powders, first based on the desired alloy composition. The wax and the polymer are then combined with the additive of the polymer and the additive mixed with the powder and then heated into a viscous substance. After gradually cooling down, processed into granular particles as raw materials.

Comparison of metal injection molding process and other processes: the machining accuracy of the machining method is far better than other processing methods, but because of the low effective utilization of materials, and the completion of its shape is limited by equipment and tools, some parts can not be machined. On the contrary, the forming process can make good use of the material, and the freedom of shape is unlimited.

Metal powder injection molding application industry

Powder preparation from MIM process materials

Through the injection molding machine, the forming blank can be obtained, and after the degreasing process, the sintered and densified into the final product, the small workpiece with precise size and complex three-dimensional shape can be produced automatically and in large quantities, and the lubrication degree of the whole process can be improved through the oil immersion process.

Type of atmosphere used in metal injection molding for sintering

Like other technologies, metal injection molding has many advantages and limitations. What are the specific limitations of metal injection molding?

Method for polishing stainless steel parts for metal injection molding

​Why is metal powder injection molding widely used in the medical industry? First, because it is economically applicable, but also close to the required shape, and second, only a little or no subsequent processing after sintering technology, also reduce a certain cost.

The principle of injection molding

In the process of CNC machining aluminum alloy shell must master the processing technology painting processing skills. Select a reasonable amount of cutting, according to the need to be processed according to the material, hardness, cutting state, material type, cutting depth selection of cutting speed.

Aluminum alloy precision parts and products are popular because of their light weight and delicate appearance. Especially in recent years, with the development of science and technology and social progress, people's demand for product diversity is getting stronger and stronger. Accordingly, the craft of aluminium alloy product does better, more can get the favour of people, market demand also can be bigger, benefit is higher also. CNC machining is one of the best machining methods for aluminum alloy shell products.

Materials made by powder metallurgy are called powder metallurgy materials (metallurgical material powders). The so-called powder metallurgy is the production of powder and consolidated (such as compaction and sintering) powder to prepare materials or part of the technical process. At present, this is an effective means to improve the performance of household appliances and develop new materials.
