Let's talk about the difference between PM powder pressing and injection molding?

PM powder pressing technology and injection molding technology are special technologies, precision manufacturing, both have good material-saving processing characteristics, in some fields, they may be more suitable for PM powder pressing technology, and some precision parts will choose injection molding technology, which depends on Due to the needs of customers and spare parts for production and processing, the following editor will explain the difference between these two technologies in depth, so that you are no longer unfamiliar with powder pressing.

PM powder pressing manufacturers talk about the advantages of powder metallurgy gears?

PM powder pressing manufacturers: What are the advantages of powder metallurgy gears? Nowadays, the variety and output of powder metallurgy gears are increasing, and the scope of application is also increasing, because its advantages are unparalleled, so what are the advantages of powder metallurgy gears? The technicians of PM powder pressing manufacturers will answer your questions:

Precision planetary gear reducer gear accessories processing and maintenance

The processing of gear parts of precision planetary gear reducer requires maintenance. First, the precision planetary gear reducer can only be installed on a flat, shock-absorbing and torsion-resistant support structure. Under no circumstances should a hammer be used to knock pulleys, couplings, pinions or sprockets onto the output shaft, as this will damage the bearings and shaft. The precision planetary gear reducer has the advantages of space saving, reliability and durability, high overload capacity, power up to 200KW, low energy consumption, superior performance, deceleration efficiency up to 95℅, low vibration, low noise, rigid cast iron box, high gear surface Frequency heat treatment, after precision machining, constitutes helical gears, bevel gears. The gear reducer is a special reducer for various reaction kettles. Its gears adopt Gleason quasi-hyperbolic tooth type and the gears are hard-toothed. It has the characteristics of large bearing capacity, low noise, long life, high efficiency and stable operation. The performance of the whole machine is far superior to that of cycloid reducer and worm gear reducer, and has been widely recognized and applied by users. The gear modulus in the precision planetary gear reducer is a very important knowledge point. The higher the modulus, the thicker the teeth. The modulus refers to the ratio of the tooth pitch t between the tooth profiles on the same side of the adjacent two teeth to the pi (m=t/π) in millimeters. Modulus is one of the most basic parameters of modulo gear teeth. The larger the modulus. If the number of gear teeth is constant, the radial dimension of the wheel is also larger. The module series standards are formulated according to the requirements of design, manufacture and inspection. For gears with non-spur teeth, the modules are different from the normal module mn, the end face module ms and the axial module mx, which are based on their respective teeth. The ratio of pitch (normal pitch, end face pitch and axial pitch) to pi is also in millimeters. For the bevel gear module, there are big end module me, average module mm and small end module m1. For tools, there are corresponding tool modules mo, etc., and the application of standard modules is very wide.
