The use of plastic parts occupies a very important position in industrial production, especially with the use of various kinds of mechanical processing and electrical processing, the plastic parts used are gradually increasing, and the application demand for plastic parts in the market is also increasing.
For home appliance plastic parts companies, the demand of the home appliance industry has brought more opportunities to the development of home appliance plastic parts companies, and the use of home appliance plastic parts is also an important part of the production of home appliances, so for home appliance plastic parts companies, ensuring the quality of basic parts is the key to the market.
The problems often occur in plastic parts are mainly cracked, and the main reasons for cracking are generally:
1, the material of the plastic itself
The internal stress resistance of the plastic itself is not good, if it is processed in an unsuitable environment, such as excessive humidity, causing some plastics to react with water vapor, and the content of recycled materials is too high, which will reduce the strength of the plastic and cause cracking.
The plastic is flowing when injection molding, if the melt temperature is too high during injection molding, the polymer chain will be overly stretched when flowing, and after cooling, the plastic crystallization, the molecular chain will shrink, and the cracking problem will occur.
3, mold design problems
The ejection of the mold should be balanced, if the number of ejection rods, cross-sectional area, release slope, and cavity surface do not meet the standard, it will produce a large back pressure on plastic products, resulting in excessive lateral shear force, so that the external force leads to the residual stress of ejection is not concentrated and cracking.
