Molds are important tools used in industrial production for molding or processing products, and their failure may affect productivity and product quality. The common causes of mold failure can be attributed to the following aspects:
Wear and Tear
During the use of the mold, due to repeated high pressure and friction, the various parts of the mold may gradually wear out.
Corrosion
Molds work in a humid or corrosive substance environment, resulting in damage to the surface or internal structure of the mold.
Design Defects
The design does not fully consider the strength, rigidity, wear resistance and other factors of the mold, resulting in the failure of the mold in the process of use.
Material Problem
The material used does not meet the requirements, such as insufficient hardness, poor corrosion resistance, poor fatigue resistance, etc., resulting in easy damage to the mold.
Manufacturing Defects
Errors in the manufacturing process, such as inaccurate dimensions, substandard surface roughness, improper heat treatment, etc., may lead to problems with the mold in use.
Fatigue Damage
During repeated loading and unloading of the mold, fatigue cracks are gradually produced, eventually leading to fracture.
Improper Operation
Operators do not operate according to the regulations, such as the mold is not properly installed, excessive pressure, improper temperature control, etc., which may lead to damage to the mold.
Inadequate Maintenance
Molds are not regularly cleaned, lubricated and maintained, which can lead to failure.
Failure of Mold Fastening Elements
Mold fastening elements such as screws, pins, etc. fail due to prolonged use, resulting in loosening of the mold structure. Understanding these common causes, you can take appropriate preventive and maintenance measures to reduce the occurrence of mold failure, improve production efficiency and product quality.
Environmental Factors
Temperature, humidity and other environmental factors have an impact on the performance of the mold, and extreme environmental conditions may lead to mold failure. Dust, debris and other foreign matter in the working environment of the mold may also enter the mold, affecting the normal work of the mold.
Solving mold failures usually requires a combination of these factors and appropriate preventive and maintenance measures.
