Plastic mold exhausting precautions The parting surface of the plastic mold is where the mold gas is discharged. If the parting surface is flat, the grinding surface is used for grinding, and the parting surface after grinding is very well attached. The gas in the cavity should not be discharged. It is necessary to open the exhaust groove on one side of the cavity. If the parting surface is a curved surface or a beveled surface, it is often vented directly due chair mould manufacturers to the accuracy of the processing, and it is not necessary to process the venting groove on the parting surface of the plastic mold.

The venting groove of Huangjiang plastic mold is often set to two levels. The first-stage venting groove is mainly closed plastic, which only discharges air, while the secondary venting groove is often deeper, which facilitates the rapid discharge of gas. The venting groove of the plastic mold should be cleaned regularly. After injection molding, many plastics tend to leave a small amount of residue on the surface of the venting groove of the plastic mold, similar to plastic powder. When the time is long, after a long period of time, these residues will block the mold venting groove, making gas discharge difficult. Therefore, the exhaust groove of the plastic mold should be cleaned in time.

The venting groove of the mold is easier to clean on the parting surface and can be wiped off directly. The venting grooves on the surface of the putter or in the sloping roof are also easier to clean, and they are often cleaned up due to their own movement. The most difficult to clean the venting groove and the most easily overlooked is the venting groove of the fixed parts between the inserts. This must be cleaned regularly.
