Maintenance of die system of PP blown plastic polypropylene film blowing machine :
① Use the secondary heating method to start the heating to avoid temperature overshoot.
② Use a pure copper scraper to clean the build-up, paraffin to clean the membrane mouth before starting the machine and reduce the impact of the precipitates on the membrane bubble.
③ Cover the protective felt in time after shutdown to avoid mold damage. (This method is used for the upper blowing machine)
④ Regularly check the temperature and current of each temperature zone and the heating plug of the film mouth to correct the temperature difference.
⑤ Correct the die level and the center point to match the traction.
⑥ Use a torque wrench to remove the mold screws and operate according to the specified torque. Molybdenum disulfide grease is used for the high-temperature screws.
⑦ Welding and cutting of molds are prohibited.
Tips: In order to avoid purchasing risks, it is recommended that you confirm the supplier's qualification and product quality before purchasing the product.
