PVC steel wire hose sometimes wrinkles during the production process.

PVC steel wire hose in the production process sometimes wrinkling phenomenon, mainly due to the following.
First, the uneven die temperature Uneven temperature will lead to uneven heating of raw materials, to be checked on the heating ring to ensure uniform nesting in the die.
Second, the cooling effect is not good Hose in the production is not fully cooled, to reduce the cooling water temperature to its complete cooling.
Third, the traction speed inappropriate Traction speed or faster or slow will affect the surface finish, the traction speed to be adjusted.
Fourth, the material impurities Impurities in the production of raw materials can cause defects on the surface of the hose, resulting in wrinkles, to the raw material replacement.
Fifth, the fuselage and parts temperature low temperature is too low Production technology can not meet the requirements of processing quality, to increase the temperature of the fuselage and components.
