The difference between a boneless wiper and a boneless wiper:

Bone-wiper: it is the principle of the skeleton through a number of support points on the wiper blade pressed on the glass, so that the blade on the various support points of the pressure average. In the process of use, due to the average pressure of each support point of the bone wiper, the degree of wear is also average, easy to appear between the wiper blade and glass friction noise, not easy to clean impurities.

Boneless wipers: boneless wipers are compared to traditional wipers with metal supports. The main difference between the two is in the working pressure: there is bone wiper blade can not withstand greater pressure. The boneless wiper itself is composed of four parts: rubber wiper strip, boneless wiper steel sheet, wiper sheath and plastic parts. The steel blade in the boneless wiper USES a whole guide force steel strip to disperse the pressure, so that all parts of the wiper blade are under uniform stress, so as to achieve the effect of reducing water marks and scratches. The steel sheet is plated to make it more resistant to rust.
