1, needle gauge work surface shall not have scratches, burrs and rust and other defects. 2, one or both ends of the needle gauge, within 1mm from the use of the appropriate width and its combination of angle angle chamfer.

Carbide bushings, also known as tungsten steel bushings, are made of refractory metal hard compounds and bonded metal through powder metallurgy made of an alloy material.

Tungsten steel bushing is mainly used for stamping and stretching. Carbide is widely used as a tool material, such as turning tools, milling cutters, planers, drill bits, boring tools, etc.,

Tungsten steel gauge is tungsten-containing steel, such as high-speed steel and some hot production model steel, steel tungsten for steel hardness and resistance to internal combustion has a significant improvement, but the toughness will drop rapidly.

High precision molds supporting the use of carbide punch precision requirements are very high, as well as product consistency, requiring mass production of each punch must be in strict accordance with the dimensional accuracy of tolerance requirements, to achieve maximum mold life. As a precision molds supporting the use of carbide pins, product consistency is a key factor, which will directly affect the mold life and product size accuracy.

Tungsten Steel Needle Gauge Company integrates production and sales, mainly selling and processing hard alloy products, and producing various types of tungsten steel molds.

Characteristics of tungsten steel lining products: The accuracy can reach 0.002mm, there are many types, and non-standard products can be customized according to customer needs.

1. Normalization: A heat treatment process in which steel or steel components are heated to an appropriate temperature above the critical point AC3 or ACM for a certain period of time and then cooled in air to obtain a pearlite like structure.

According to the different materials selected, punching needles can be divided into SKD punching needles, SKH punching needles, and ASP punching needles

At present, tungsten steel punches in China can be divided into three categories based on their material and user usage: low, medium, and high.

The reason and solution of punching easily broken (1)1, closed height is too low, punch cut into the knife-edge part is too long. Solution: adjust the closure height, so that the punch head appropriate length.

As the core of the stamping die work, the punch is to make the material separation or plastic deformation, so as to obtain the necessary parts, stamping die supporting operations play an important role.

Tungsten steel bushing product features, precision can reach 0.002mm, many types, according to customer needs customized non-standard products.

1, plastic mold thimble can also be used inside the mold, it can play a solid role, called the needle.2, in the plastic mold, the product from the mold on the separation, but also the most commonly used;
