How about Dalian Hengyi Machinery Co., Ltd.?

Hengyi Machinery is located in Yingchengzi Industrial Park, and the scale is OK. My company asked them to process parts, so I went. Just like on the spot, his boss is very kind and enthusiastic, and his employees are well treated. If the wages of skilled workers are quite high, Yingchengzi belongs to the suburbs and the price is much cheaper than that in the city. The cost is not very big.
