The reasons why we can achieve such high tolerance is because we deploy very fine metal powder and our technology is capable of forming components of high accuracy and smooth surface with a precise mould created by our reliable partners.
This pinion gear's teeth are so tiny that it is very difficult to create by other conventional production methods due to its size, accuracy, and lead time caused by many processes. It is not favourable even with CNC-machining when it comes to mass production.
On the other hand, our technology, micro metal injection moulding (µ-MIM®) can produce them more quickly and precisely, so that it eventually leads to cost reduction.
