The production of brake pads by the barrel molding process can be said to be the oldest production method. Former small brake pad production plants in China still use this production method, that is to say The products sold in the drum brake pad market in China are mostly the products of the production process.
The product has the advantage of increasing production efficiency, but the inherent quality of the product is extremely Stable, in terms of specific gravity performance, all parts will be deteriorated, because the compactness is not The problem with consistency is that the friction performance and wear rate are unstable.
