My uncle’s factory now need emergency processing a batch of parts, slack adjuster things, but because time is limited, some of the original is not ready, so he thought of buying slack adjuster from other companies. He said that now the domestic about slack adjuster something less, but slack adjuster is widely applied in various fields, so want to specialize in the development of slack adjuster. But it takes a long time to prepare, to learn from foreign technology, understand the source, then gradually began to develop. But uncle saw slack adjuster prospect, I think it is not wrong, I am always support his. Slack adjuster will bring the income for the factory.
