Question 1

Can FOTMA manufacture tungsten carbide parts from my drawing or sample?

Accepted Answer

Yes. FOTMA produces custom carbide components from 2D/3D drawings or physical samples. Our engineers review geometry, tolerances, grade and surface finish, then route the part through pressing, sintering, CNC machining, grinding, EDM and polishing as required.

Question 2

How do I choose the right cemented carbide grade?

Accepted Answer

Grade selection balances hardness against toughness. Lower cobalt binder content (around 6%) gives higher hardness and wear resistance for abrasive applications, while higher cobalt content (around 10 to 15% or more) improves toughness for impact loads such as shredder blades and mining tools. Share your operating conditions and we will recommend a grade.

Question 3

Which quality standard does FOTMA follow?

Accepted Answer

All production procedures, including sintering, CNC machining, grinding, EDM and polishing, are operated under an ISO 9001:2015 quality management system. Dimensional inspection records and material documentation are available on request.

Question 4

What information should I provide for a technical review?

Accepted Answer

Please send drawings (PDF, DWG, STEP or IGES), material or grade requirements, tolerances, surface finish, annual volume and the application environment. This allows our engineers to confirm manufacturability and propose the most cost-effective process route.

Question 5

Does FOTMA supply materials other than tungsten carbide?

Accepted Answer

Yes. In addition to cemented carbide, FOTMA supplies tungsten alloys, tungsten-copper and molybdenum-copper electronic packaging materials, molybdenum products, nickel and nickel alloys such as Inconel 625 and 718, heating elements, ceramic products and CNC machined parts.
