YDTech® supplier tungsten carbide dies, WC-Co punches, wolfram moulds, stamping parts, WC-Co ejector pins cylindrical pins! manufacturers of tungsten dies punch pins, carbide molds, wolfram stamping needles, WC precision convex molds in china.
tungsten carbide punch pins as tungsten carbide steel punching needles, which are the fine ground of a hard alloy round bar. Tungsten carbide punch pins have the properties of high precision, high hardness, good strength, long service life, corrosion resistance, and durability, and are suitable for the hardware and electrical processing industry.
in general, tungsten carbide punch pins can be divided into many different types, such as hexagonal punch pins, elliptical punch pins, diamond-shaped punch pins, fan-shaped punch pins, special-shaped punch pins, square punch pins, trilateral punch pins, tap punch pins stepped punch pins and straight punch pins.
stamping die is a special kind of process equipment for processing materials into parts in cold stamping process, which is called cold stamping die. Stamping, a method of pressure processing, is the use of a die mounted on a press to apply pressure to a material at room temperature, causing it to separate or plastically deform, so as to obtain the desired part.
tungsten carbide punch pins can be used for metal stamping production or fabrication, injection mold, plastic mold, and die. they can also be used in plastic mold. Plastic mold tungsten steel punch pin can also be used in the mold. Tungsten carbide punch pins can be used to pass through longer and finer holes.
our hardened ground parts meet the most demanding specifications for the most challenging applications. Our capabilities include diameters ranging from .004 to 1.25 inches while holding tolerances down to.0001 inches and surface finishes down to 2 micro.

Punch punch is a part used in a mold to mold the inner surface of a product, also known as a punch, upper die, male die, etc. The main function of punch punching needle is to deform or cut the material through direct contact with the material. According to different materials, punch punch needles can be divided into SKD punch pins, SKH punch punches, ASP punch punches, tungsten carbide punch needles and high-speed steel punch pins
properties of tungsten moulds punching pins, carbide punching dies needles
SKD punching pins: made of SKD special mold steel, suitable for various production needs. SKH punch pin: high-speed steel material, with high hardness and wear resistance. ASP punch pins: specific materials for specific process needs. Tungsten carbide punch needle: It has high hardness and high wear resistance, and is suitable for demanding processing environments. High-speed steel punching needle: high hardness, suitable for general stamping operations.
as one of the precision mold parts, tungsten carbide punch pins can be used to enhance the strength and prevent the thimble from being broken. tungsten carbide punch pins always have high requirements in processing. one of the most basic properties of tungsten carbide punch pins is wear resistance. And hardness is the major factor to affect wear resistance. The higher the hardness of the punch pin, the smaller the wear and the better the wear resistance.
