1、看卷管机厂家的规模大小，一个厂家好不好，不要听人讲，如果有时间，一定要自己去厂里看看。看厂房占地面积：那些占地百多平方或者几十个平方的厂，可能有价格优势，但是随时可能改行或者跑路。

1, look at the size of the winding machine manufacturer, a manufacturer is good, do not listen to people, if you have time, must go to the factory to see. See workshop covers an area of area: those cover an area of more than 100 square meters or dozens of square factories, there may be price advantage, but at any time may change line or run.

2、看卷管机厂家产品的质量怎么样，关于质量，各个厂家都说自家的好，那作为经销商应该如何以低成本检验厂家说法的真伪呢？发样品！实力厂家对于样品门，在工艺上绝对是精益求精的，但是业内人士都知道，样品门是厂家精工细作的小批量产品，跟批量产品质量是无法相提并论的。

2, look at the quality of the tube machine manufacturer's products, about the quality, each manufacturer said their own good, that as a dealer should be how to test the authenticity of the manufacturer at low cost? Hair samples! Strength manufacturer is to sample door, it is keep improving absolutely on craft, but the personage inside course of study knows, sample door is the small batch product that manufacturer Seiko makes carefully, with batch product quality cannot be compared.

3、看卷管机厂家的售后服务，服务是销售环节中的第一环，也是最后一环，同时是最重要的一环。因为现在门产品同质化越来越严重，价格越来越透明，甚至杀价的厂家越来越多，在价格竞争白热化的阶段，很多卷管机厂家因为舍弃了利润，就忽视了服务。

3. Look at the after-sale service of the coil machine manufacturers. Service is the first and last link in the sales link, and the most important one at the same time. Because now the door product homogenization is more and more serious, the price is more and more transparent, and even more and more bargaining manufacturers, in the stage of white-hot price competition, a lot of tube machine manufacturers because of abandoning the profit, ignore the service.
