Forging is divided into manual forging and die forging Die forging refers to the metal is first heated to liquid or soft state and then put into the mold through the mold up and down die closed secondary molding sometimes need many times

Profile mold manufacturing is generally after forging, cutting, heat treatment and other processes. In order to ensure the manufacturing quality of the mold, reduce the production cost, the material should have good forgoulability, machinability, hardenability, hardenability and grinding; There should also be small oxidation, decarburization sensitivity and quenching deformation cracking tendency.

In recent years, the rapid development of precision forging technology has promoted the progress of automobile manufacturing industry. Cold forging and warm forging are more and more used in automobile industry, and the product shape is more and more close to the final shape. Precision forging will be developed with the progress of technology and related technology in the future.

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.

Aluminum surface shape diagram matched by different processing processes Taking the aluminum alloy profile mobile phone case as an example, the cleaning materials in different processing processes of detergent are introduced in detail.

Anodic oxidation, photocatalytic oxidation of a metal or aluminum alloy. The process by which layers of air oxide film are produced on aluminum (anodized) metal (anodized) in a lithium battery electrolyte and a special process standard due to the effect of additional current. Anodizing, if not very pointed, is hydrochloric acid anodizing.

3D drawing is required. In the handboard modeling industry, it is difficult to evaluate the price of the handboard without 3D drawing. Moreover, 3D drawing is used for product engraving and milling forming, which is an indispensable chart file in processing.

China's powder metallurgy industry has experienced rapid development for nearly 10 years, but it still has the following gaps with foreign counterparts :(1) there are many enterprises, small scale, and great difference in economic benefits with foreign enterprises. (2) products cross each other, enterprises bargain with each other, and competition is extremely fierce. (3) most enterprises lack technical support, backward research and development capabilities, and low product grade, making it difficult to compete with foreign countries. (4) lack and disturbance of reinvestment. (5) backward process equipment and supporting facilities. (6) the product export is small, the trade channel is not smooth.

The first Formnext + PM South China will be held in shenzhen from September 9 to 11, 2020. The exhibition will cover a series of advanced materials, technologies, equipment and products such as materials, powder metallurgy, additive manufacturing and reprocessing, bringing new business opportunities to the manufacturing industry in China and even Asia.

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.

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.
