How to use powder metallurgy lubricant correctly?

The molding of powder metallurgy products includes multiple processes. No matter which process it is in, powder metallurgy lubricants are one of the indispensable auxiliary materials, especially mold release lubricants, which have a great impact on the quality of powder metallurgy products.

To make powder metallurgy products, the first step is to mold the metal powder to make it a low-density workpiece; then the metal powder is reinforced by sintering to obtain powder metallurgy products with certain hardness and shape. In this process, powder metallurgy lubricants play a very important role, especially in the later demolding process.

When choosing powder metallurgy lubricants, be sure to choose high-quality non-polluting products, so that even when a large powder metallurgy product needs to be molded with a lot of pressure, the powder metallurgy lubricant can maintain its due role.

In terms of powder metallurgy release agent, it can reduce the release force by half, greatly prolong the service life of the mold and the machine; and the damage and wear caused by the release will be less. Since the decomposed product of the powder metallurgy release agent is a gas, it will not leave dirt on the surface of the powder metallurgy product due to sintering.

Not only that, if a powder metallurgy release agent is used to coat the inner wall of the forming mold, it will have a positive effect on eliminating the problem of mixed lubricant evaporation and increasing the density of the control workpiece.

L466X powder metallurgy lubricant is suitable for metal powder metallurgy. Compared with traditional lubricants (such as zinc stearate, etc.), it has better dispersibility, lubricity and mold release. Moreover, there are very few residual impurities in metal products, which can be completely decomposed, without residue, without pollution, and without carbon deposition and black spots. The finished product has excellent surface quality and excellent performance.

1. In the sintering process, there is no residue and no pollution, and the decomposition is complete.

2. The addition amount is small, the green density and sintered density are increased under the same pressure, and the unqualified products and waste are reduced.

3. Reduce the pressure required for the density gradient of the part to a minimum.

4. It can be widely used in the cold pressing process of powder metal parts, (automobile shock absorbers, refrigeration compressor parts, production of automotive mechanical parts, etc.) to provide its lubricating properties.
