The blow molding machine is selected from Ningbo Junyu Machinery, with years of industry experience and a one-stop equipment service supplier.

Bottle blowing is not full or irregular: it may be due to insufficient heating temperature or insufficient blowing time. It is recommended to increase the heating and blowing time appropriately.

Thin shell or fracture at the bottle mouth: It may be due to insufficient blowing pressure or improper internal design of the mold. It is recommended to increase the blowing pressure appropriately or replace the high-quality mold.

Bottle deformation or rough surface: There may be a problem with the mold design, and the mold and blowing flow rate can be adjusted again.

Shrinkage or collapse at the bottom of the bottle: It may be due to a long heating time or a short blowing time. It is recommended to reduce the heating time and increase the blowing time appropriately.

The plastic melt is uneven, resulting in color difference or bubbles: it may be due to unstable machine temperature or moisture in the raw materials. The temperature can be adjusted appropriately and fresh raw materials can be replaced.

Excessive machine noise or severe vibration: It may be due to worn or improperly fixed machine parts, requiring repair and replacement.

Pipeline blockage or air leakage: It may be due to incomplete cleaning of the pipeline or loose connections, which require cleaning and checking for tightness.

Control system malfunction: It may be due to poor circuit connection or equipment damage, which requires inspection and replacement.
