1989年第一次全国小型机械产品交易会最近召开。会议成交平淡。预计,今年全国小型机械产品市场需求将稳中有降。手拉葫芦、台钻、低压阀门、小空压机等产品市场竞争激烈,受原材料涨价影响 In 1989, the first National Small Machinery Trade Fair was held recently. The deal was dull. It is expected that the market demand for small-sized mechanical products will drop steadily this year. Chain hoists, bench drills, low pressure valves, small air compressors and other products have fierce market competition and are influenced by the price of raw materials.
