In india,there are also many nail making machine manufacturers,take Gurinder Engineering works as an example.
Their website is: www.nailmakingmachines.com/
The difference between our technolody and from India is:
Our machines C series has lower noise,can lubricate its parts automatically,just adding the engine oil in the oil tank is ok.
While the noise of made in india is bigger because their structure is the old structure of Chinese technology.
Also there are quality difference,such as the weight of our model Z94-4A is 2 tons,while some low quality products are only 1.5 tons,this will affect the quality of the machines and affect the production of nails greatly.
