Sintex a/s, Denmark, has published a number of Powder Metallurgy case studies highlighting the capabilities of PM technologies for a range of applications. The case studies are available on the company’s website in English, German and Danish.

 

High strength requirements fulfilled using MIM

The first case study focuses on the use of Metal Injection Moulding (MIM) technology to enable a customer to fulfil the high strength requirements of a sensor housing, in the same geometry as plastic but with the same strength as steel. The key benefit of MIM in this application is that it enables a more complex part geometry than is possible by machining, and for the part to be produced as a single component in a single step process, reducing time and cost.

 

Surface treatment strengthens joins

This case study looks at the production of a wear resistant coating for friction plates consisting of a wolfram carbide hard metal coating. The friction plants are used in wind turbines and the aim of their development was to reduce friction during use. Further key benefits of the new wear resistant coating were the achievement of higher friction plate strength and extended lifetime.

 

Powder Metallurgy fulfils high requirements

In this case study, Sintex presents the development of a custom PM solution for an automotive customer with strict material and quality requirements. The customer required higher corrosion resistance without a significant cost increase. Sintex’s case study examines how the company met this requirement through a combination of new material development, sparring and proposals for design enhancements such that the higher material price was offset by mass savings, and the development of a fully automatic production line.

 

Stator design with SMC

This case study looks at the benefits of SMC in the production of stators for cheaper, smaller and more efficient motors. An example is provided of the production of a stator with an outer diameter of 80 mm, length of 20 mm, six stator teeth, outer rotor diameter of 28 mm and four poles, comparing the results of producing the part in iron against the results with SMC.

 

World-class sound using innovative SMC solution

In the final case study, Sintex looks at the use of SMCs in a loudspeaker produced by a Danish speaker manufacturer. SMCs are an attractive solution for applications that require low losses, in particular at high frequencies, as the advantages of SMCs increase at higher magnetic frequencies. The loudspeaker produced through this collaboration was said to be the first loudspeaker to contain a magnetic system made of SMC.
