Benefit: Cost Saving
Main Forming Process: Metal Injection Moulding
End Use Sector: Consumer Goods
Material: Stainless Steel


These components are responsible for the transmission of movement between the pedals and the wheel of a bicycle. It is a system of transmission of magneto-mechanical movements and the coupling of both components is essential for proper work. The main difficulty at the time of the development of the parts was to achieve a perfect filling in such fine teeth and achieve a perfect coupling of both parts. Therefore, we have very strict dimensional requirements. The main advantages obtained doing these parts in MIM technology are the cost savings in manufacturing, mainly saves operations of machining and we obtain parts with good mechanical properties for the work of the parts.
