Carbide Punches
Carbide Punches are kinds of special punches mainly used for metal stamping dies, press dies, progressive dies or transfer dies, or used for cutting some sheet metal, medical bills in the industrial production process.
Carbide Punches as its name mentioned are made of tungsten carbide material. Or called WC or cemented carbide or hard metal (HM).
As we know, carbide is a difficult-to-cut material. So it needs special equipment to process and machine the material.
Now we will introduce a few carbide punch manufacturers in USA, Japan, China and India.
Endurance Carbide — Carbide Punches Manufacturer in the USA
Endurance Carbide as its name is a manufacturer of carbide components in the USA, It produces various kinds of carbide punches, carbide dies, carbide bushings, carbide gauges, carbide form inserts, etc.
Regarding the manufacturing of carbide punches, according to its product line, it mainly produces round and cylindrical carbide punches for automotive, aerospace, and fasteners industries and usages.
If you require the round shaped carbide punches, Endurance carbide is your good choice.
Oberg Industries — Carbide Punches Manufacturer in the USA
Oberg Industries, according to its product line, can produce various kinds of carbide punches, which also include carbide die inserts. Maybe it also can produce a full set of tooling. Obviously, it has a strong design and productive ability to manufacture carbide punches.
But due to it being a manufacturer in the USA, its manufacturing cost may some high, for some local needs of carbide punches in the USA, it is a very good choice.
Langdi Precision — Carbide Punches Manufacturer in China
Langdi Precision, It is a professional carbide punch factory in China. As a carbide punch supplier, it can produce various kinds of custom carbide punches, whether it is in rectangular & square shape or round & cylindrical shape.
It is equipped with Japan-made Profile Grinding machines, Japan-made Plane Surface grinding machines (small type) and Japan-made wire-cut and sinker EDM machines. This makes it able to produce custom-made carbide punches with an ultra-precision tolerance of ±0.001mm.
Due to its advanced profile grinding and surface grinding technology, it also can have a very nice RA surface roughness.
As a manufacturer and exporter of tungsten carbide punches in China, Langdi Precision can provide a full range of machining services for global customers.
MISUMI — Carbide Punches Manufacturer in Japan
As one of world’s biggest standard mold components suppliers, MISUMI also supplies carbide punches in standard type. If you want to buy some standard carbide punches and dies, you can choose the MISUMI brand.
MISUMI has headquarters both in Japan and the USA, it can be regarded as a carbide punches manufacturer in Japan and the USA.
Dictools — Carbide Punches Manufacturer in India
Dic Tools is a cutting tools manufacturer in India. Actually, the carbide punch is also a cutting tool. According to its product line, it also can produce some kinds of round-shaped carbide punches.
But its main category may be more solid carbide cutting tools.
Essential Ability of a Tungsten Carbide Punch Manufacturer
To make the carbide punches, a manufacturer should have profile grinding machines, plane surface grinding machines, JG grinding machines, Wire-Cut EDM, or Erode EDM. These are not normal machines, except for the plane grinder, one of them costs more than 140 thousand US dollars. A set of equipment may cost more than 700 thousand US dollars.
When we have these high-end machining and grinding machines, we also need experienced CNC machinists to operate them.
Talking about the mechanical machining technology, we know that CNC milling is fast by 3-axis, 4-axis, or 5-axis high-speed milling machine, CNC turning is also the same by NC lathes. But for the EDM and Grinding, they are slow work. But slow work can get better quality. Especially for grinding, it may be the slowest work in the various kinds of machining technologies. But it can get excellent surface roughness and excellent tolerance.
A carbide punch manufacturer knows the key to this. They need to train sophisticated CNC machinists and need to use world-advanced machining equipment. Then they can do the job well.
Tungsten carbide punches need to be used with the carbide die inserts together. There are also some related stamping die components, like stripper inserts, stripper plates, guiding plates, main plates, etc. A professional tungsten carbide punch manufacturer usually has the ability to produce these kinds of stamping die components.
