Hårdmetallverktyg med extrema toleranser för ett medicintekniskt företag - Sollex

Tungsten carbide tools with extreme tolerances for a MedTech

Sollex supplied carbide tools to customer drawings with extreme tolerances for a very demanding international client in the medical technology sector. The dimensions of the tool have been measured in exact hundredths with tolerances down to five thousandths (+ 0 / -0.005 to be exact). Similarly, the surface roughness Ra 0.01 has touched the extreme. In the project, Sollex has delivered unique measurement protocols where we measured the tool's tolerances and surface smoothness.

In January, Sollex delivered another 10 new shipments of extreme tolerance carbide tools for injection molding plastics. This shipment demonstrates Sollex's high repeatability in producing complex cemented carbide tools with extreme dimensions and tolerances. 

Because cemented carbide is extremely hard and wear resistant, cemented carbide molds can be used to produce high precision components with long life and high accuracy. Carbide is also resistant to high temperatures and corrosion, making it suitable for use in abrasive environments. Injection molding tools are expensive to produce, but their long life and high performance make them a cost-effective option in the long run. Injection molding is a manufacturing process that can produce thousands or millions of identical plastic parts, it is critical that the molding tools are durable enough to withstand the wear and deformation that occurs during the injection molding process.

Sollex can also offer the nearly impossible - making radial transitions in cemented carbide tools. The radial transitions that Sollex can provide are between two thicknesses of 0.4 mm and 0.1 mm in cemented carbide tools. Radial transitions provide a reduction in capillary force in the production material where the cemented carbide tool is used, compared to linear transitions.

In the carbide tool project, Sollex has truly excelled in developing unique carbide tools for customers with extreme dimensions, tolerances and surface smoothness in tool design. We are proud and pleased with our beautiful knives and can now say that we can also manufacture cemented carbide tools.
