Near Net Shape Forming
Near-net forming is based on new materials, new energy, mechatronics, precision mold technology, computer technology, automation technology, numerical analysis and simulation technology and other multidisciplinary high-tech achievements, transforming the traditional blank forming technology, so that it changes from rough forming to high-quality, efficient, high-precision, lightweight and low-cost forming technology. It enables the formed mechanical components to have precise shape, high dimensional accuracy, shape and position accuracy and good surface roughness. This technology includes near-net shape casting forming, precision plastic forming, precise connection, precision heat treatment modification, surface modification, high-precision mold and other professional fields, and is a comprehensive integration technology of new processes, new equipment, new materials and various new technological achievements.
Barrels and liners ：
In the moving parts, because of long-term friction and wear of parts, when the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced, so the designer in the design of the choice of lower hardness, better wear resistance of the material for the bushing or bushing, which can reduce the wear of the shaft and seat, when the barrels and liners wear to a certain extent for replacement, which can save the cost of replacing the shaft or seat, the material requirements are low hardness and wear-resistant, the inner hole of the bushing is ground and scraped, and can achieve high matching accuracy;
The hot isostatic pressing (HIP) process enables the housing bushings to be treated with hot isostatic pressing to achieve both of these characteristics and a significant increase in wear resistance for a longer service life, thus reducing costs and increasing efficiency.
Tee:
Tee is also known as tee fittingsTee fittings, tee joints, etc. It is mainly used to change the direction of the fluid, and is used in the main pipeline to branch the pipe. Can be classified by pipe diameter. Generally with carbon steel, cast steel, alloy steel, stainless steel, copper,Made of aluminum alloy, plastic, argon asphalt, PVC and other materials.
Tee is to have three openings, i.e. one inlet and twoOutlet; Or two imports, one outlet of a chemical pipe fittings, there are T-shaped and Y-shaped, there are equal diameter pipe mouths, there are also reducer pipe mouths, used for threeWhere the same or different pipes meet. The main function of the tee is to change the direction of the fluid.
Used in aerospace, deep-sea oil exploration, the three tees adopted are manufactured by hot isostatic pressing process, which can better meet the requirements of wear resistance and corrosion resistance under high pressure.
