Friends who touch the mold industry know that SKD61 thiming and SKH51 are used more in plastic mold.When the client is consulting or ordering a thimble, many times will ask about the hardness, wear resistance and durability of the die thimble.Mold parts manufacturers of changsha borun embellish think actually, plunger wear resistance and durability are not completely depend on the material hardness, but different material has its own scientific and reasonable hardness.

How to improve the durability of thimble in mold?

SKD61 thimble, for example, air cooling quenching, quenching temperature 1020-1020 degrees, the surface hardness above HV900 (HRC60-67 degrees), and the use of 60-62 HRC hardness, heat treatment deformation is small, can be nitriding surface nitriding processing, processing of the product has better wear resistance.With high technology polishing technology, it can reduce the surface friction coefficient, enhance the wear resistance and corrosion resistance, and ensure the use of the mold more than a million times.Internal tempering hardness hrc40-45 degree, after secondary tempering, SKD61 thimble and high toughness, high heat resistance using temperature up to 550 degrees, suitable for high temperature mold long use.

It is not difficult to see that when the thimble is processed in the mold, each material or each mold accessory has a suitable hardness in the application.Only when the appropriate hardness is selected, and the relevant technical treatment, the thimble in the mold will achieve the desired effect, and the wearability and durability will naturally improve.
