Why does the incision position always shift when the toy blow molding machine is stretching and blowing?
Why is the bottom of the product not full during stretch blow molding? How to deal with it?
The main reasons why the bottom of the product is not full during the stretch blow molding process are:
①The blow molding pressure is not high enough and the blowing air is insufficient.
②The parison temperature during blowing is too low.
③The parison inflation speed is too slow.
Why does the incision position always shift when the toy blow molding machine is stretched and hollow blow molded? Solution:
① Check whether the high-pressure filter on the side of the mold is unobstructed to prevent it from affecting the supply of high-pressure air.
② Check the air flow control component of the blower to ensure the correct setting value and that the inside is smooth and free of obstructions.
③ Ensure that the air blowing can be completed in the shortest time, otherwise it will bring additional cooling to the material during bottle blowing.
④ Make sure that all ventilation holes (exhaust holes) on the mold are not blocked.
⑤ Increase the blowing pressure appropriately.
