If you want to test more of our Cemented Carbide or Carbide Cutting Tools, you are warmly welcome to place trial order.

Do you Charge the mold for the Standard Cemented Carbide and the Irregular ( no-standard) Carbide??

As to the Cemented Carbide Production, the initial mold cost is really very high, for any type of mold for pressing, the materials plus the labor, it will be 250 USD at least or more.

So, our mold policy for a new type of Carbide that we have never made is:

1) In principal, we don’t want to charge the die or tooling to increase the burden of our client to develop a new product or to place he order this new carbide (or carbide parts ) to us.

2) Even we have to charge the mold cost, we will consider all the aspects of our business carefully and offer and charge you minimally, the mold charge can’t exceed the real cost the mold materials and machining cost, the labor cost to make a new set of mold will be bear by us..so, our mold cost are always very lower than our competitors.

3) For some times, we charge the mold in a attempt to show the sincerity of a new client toward a new business relationship with us. If he or she is very sincere and the order of this type of Carbide is very attractive, we will share the mold cost or even give up the mold charge.


4) For samples, If there are the similar molds or close carbide available, we suggest the client to use the similar one available or make some machining.


5) Mold is just a kind of tooling for the production of Cemented Carbide, so, we never want to earn any profit from the mold making, as per our policy, we refund the mold cost charged for this type of cemented carbide when its

 order quantity is accumulated to 80 KGS for simple Cemented Carbide or 160 KGS for the irregular or complicated Cemented Carbide

Since Rydmet Carbide produces both Standard and Custom-made Cemented Carbide ( hard metal) or Cutting Tools, what is the percentage for each?

As per our statistics of our recent years’ sales and inquiry records, we found that 75% of our Cemented Carbide we made are irregular or non-standard or Custom-made, we make them as per the Client’s Specific Drawings or Prints.

Even for the Standard Carbide Parts or components, the sizes or geometries vary from one client to another. Perhaps, the innovation or changes of the design can help increase the performance of the Cemented Carbide Parts, Components in the course of working.

what is kind of Cemented Carbide do you make???

We can make the Carbide or hard-metal in sintered condition (un-ground) and in ground condition ( by grinding, machining, EDM) to the required dimensions or geometries, this kind of ground carbide are usually called Cemented Carbide Wear Parts or Cemented Carbide Components.


We can also use our CNC tool grinder to grind our Cemented Carbide Rods or Cemented Carbide Blanks into Solid Carbide Cutting tools

Are you manufacturers (Cemented Carbide and Carbide Tools ) or trading Company ?

Rydmet Carbide is a professional Cemented Carbide and finished carbide cutting tools manufacturers in China.

We can make the Cemented Carbide (or Hard metal) from the Materials ( Tungsten Carbide and Cobalt) in the form of Powder to the sintered carbide or finished Carbide Tools.

What is Cemented Tungsten Carbide or hard metal?

Tungsten is a very hard and dense metal, mined from Wolf eremite ore and symbolized by a "W" on the periodic table of elements. It melts at an extraordinary 6,192 degrees Fahrenheit, the highest melting point of all metals. On its own, tungsten is vulnerable to scratches and damage just like any other metal, such as titanium and steel. Tungsten gains its extreme hardness when it is combined with a carbon alloy, turning it into tungsten carbide or WC. It then has a hardness of 8.5 to 9.5 on the Mohs Hardness Scale. Tungsten carbide is four times harder than titanium, twice as hard as steel.


 Tungsten carbide is a homogeneous mixture of tungsten carbide grains in a tough cobalt binder matrix. The tungsten carbide grains are fused into a solid matrix of cobalt metals. The term cemented carbides comes saying that the metal carbide’s grains are “cemented” in the binder metal’s matrix. The fusion process is called liquid phase sintering, or sinter for short.


 While there are many different grades of Tungsten Carbide available containing various additives for a variety of applications, on the most basic level the primary properties of any given grade (Hardness and Toughness) are determined by the ratio of Tungsten Carbide to Cobalt. In general, more a lower percentage of Cobalt will produce a harder but less tough material and a higher percentage will produce a tougher but softer material.

What does the name “ RYDMET” mean?

1) RYDMET , as the name of the company, it has its own meaning, that is Right Your Desirable Materials, Economical, Top-quality.


2) RYDMET is also a registered Brand and Trade Mark, it is suitable for the brand of our Cemented Tungsten Carbide and Carbide Tools, Components, and Wear Parts.
