Why do plastic injection molds crack during operation? This is a serious problem that urgently needs to be addressed. In recent years, although significant progress has been made in domestic plastic injection mold technology, there is still a certain gap compared to foreign manufacturing standards. Various factors can lead to mold cracking during operation.

The primary reason is poor mold material, which can cause fragmentation during subsequent processing. Secondly, improper steel heat treatment processes, such as incorrect quenching and tempering operations, can result in mold deformation. In addition, insufficient mold grinding flatness can also cause deflection deformation. Defects in the design process should not be overlooked, such as insufficient mold strength, overly close blade spacing, unreasonable mold structure, and inadequate number of mold plates without base plates or support feet. Improper wire cutting, such as incorrect wire cutting gaps or lack of deburring, is another cause of mold cracking.

The selection of punching equipment is also crucial. A punch press with a small tonnage, insufficient punching force, or excessive mold adjustment depth can all cause damage to the mold. Smooth material ejection is essential; issues such as not performing demagnetization before production or encountering broken needles, broken springs, and other material jams during production can lead to problems. Lastly, inadequate production awareness is also a significant factor causing mold cracking, such as inaccurate positioning, not using air guns, and continuing production despite cracks in the mold plate.
