Toughness Tungsten Carbide Pins With Fatigue Fracture Performance

Toughness Tungsten Carbide Pins With Fatigue Fracture Performance​

Tungsten Carbide Pins Introduction:

The precision mold inserts pin flow and slide along the surface of the cavity when plastic deformed in the mold cavity. Thus, it causes severe friction between the surface of the cavity and the insert pin, which makes the insert pin malfunction due to wear. Therefore, the wear resistance is one of the most basic and important properties of the pin. And the hardness is the main factor affecting the wear resistance. In general, the higher the hardness of the insert, the smaller the wear and the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. The basic performance of conventional precision mold back inserts is as follows:

• Wear resistance
• Toughness
• Fatigue fracture performance
• High temperature resistance
• Corrosion resistance

For the requirements of precision mold machinery manufacturing enterprises in Suzhou area, our company produces custom-made precision tungsten steel rear mold inserts pins. The specifications of the drawings are as follows:

The size specification of tungsten steel rear mold insert pins is PCA-6/2.5/1.03/0.013*48.823L and the tip size is φ0.013. It belongs to ultra-precision fine inserts pin and need to be equipped with precision injection molds for fixed molding operations. The precision requirements are very high. The whole set of molds requires the consistency, each specification is to ensure the precision production of the injection molds.

Technical parameters:

The custom-made tungsten steel rear mold insert head diameter is φ0.013. by high-quality tungsten steel material and then deep-precision processing, the injection mold tungsten steel rear insert pin is tested and qualified by precision testing equipment.

Tungsten Carbide Pins Advantage:

National high-tech enterprise certification, the accuracy of the shape tolerance is ±0.002.
