Tungsten disulfide dry lubricating coating is prepared by adding with tungsten disulfide nanopowder as a lubricating additive. Tungsten disulfide dry lubricating coating is a lubrication method that can better solve the situation that the product cannot use the mold release agent and the injection mold is difficult to stick and demold. In other words, tungsten disulfide can be applied to the oil-free lubrication of mechanical parts or molds, and it does not affect the size of the mold.

For example, during the production of toothbrushes, some manufacturers are required to not use mold release agents, which makes it difficult to remove the mold core. And plastic often adheres to the mold core. So, toothbrushes cannot be produced normally. After treating these small mold cores with WS2 dry lubricating coating (16 small mold cores per toothbrush mold), the problem of demolding was solved, and there was no plastic adhesion, so that the production proceeded smoothly.
