Tungsten carbide manufacturer

Thanks to the expertise of our technicians, modern IT support and extensive experience in the field, Sigmacarb is able to offer you a design service that aims to develop even the most complicated requirements.

By looking at specifications, designs, prototypes and samples, our customers can follow the entire design procedure, as well as the feasibility analysis and project schedule.
 

To guarantee high quality standards for our products, we carry out quality checks at every phase of the production process right through to the finished product.

We have a well-equipped and modern laboratory.  This allows us to examine not only the physio-technological and metallographic characteristics of our materials, but also their size and quality requirements:

• 3D optical measurement machines CNC;
• Metallographic microscopes;
• Hardness tester HRA;
• Density balance;
• Stereomicroscopes;
• Measuring projector;
• Several other instruments.

The creation of a high performance product begins with choosing the right mix of materials for your needs. Cemented carbides are made using different compositions of WC, TaC, TiC, NbC, Co/Ni and other substances that determine how hard a product will be, depending on its intended use.

We have countless different types of extremely high quality mixtures capable of satisfying all requirements.
On request, we can also create new mixtures to improve and increase the lifespan of your product.

• If you need any help with making a decision, we’ll be happy to advise you.

We can offer you interesting storage solutions for those products you may often require in large quantities throughout the year.

Here are your advantages:

• You have tailor-made stock at no extra charge;
• You save on production costs;
• Our delivery times are shorter.

We are able to press geometrically complex shapes, with pinpoint precision, even when using raw workpieces.

Thanks to our well-equipped range of press machinery, we can comply with requests of any type and size:

• Several electric powder presses CNC DORST, 30 tons, automatic;
• Several mechanical powder presses CNC DORST, 15 tons;
• Various hydraulic powder presses, from 30 to 350 tons;
• An isostatic press SIMAC.

We have sintering furnaces of various dimensions. They enable us to reduce delivery times.

We have a specific department for planning, construction and maintenance of the moulds.
