niveauet af formmontør og niveauet for formdesign, niveauet af formmontør og niveauet for formdesign, niveauet af formmontør og niveauet for formdesign, niveauet af formmontør og niveauet for formdesign. Så, niveauet af formmontør og niveauet for formdesign? niveauet af formmontør og niveauet for formdesign:
1. niveauet af formmontør og niveauet for formdesign:
niveauet af formmontør og niveauet for formdesign: niveauet af formmontør og niveauet for formdesign.
The shrinkage after processing is the shrinkage of the products after a period of time after demolding, and the post-shrinkage is generally small compared to the molding shrinkage.
The first cause of post-contraction is the relaxation of the internal stress of the article. For polymers with a rigid molecular chain, the post-contraction of the product is relatively large; this is mainly because the rigid molecular chain moves slowly, and its molecular chain changes from one state to another, requiring a long realignment process.
Derfor, the post-shrinkage time is relatively long, and the post-shrinkage rate is relatively large. På den anden side, rigid molecular chains tend to generate internal stress, and slowly stress relaxation occurs after molding. The second cause of post-contraction is the continued crystallization. For the complete crystallization, and the crystallization can continue at normal temperature, thereby causing a slight shrinkage of the product.
2. Average shrinkage rate:
Since the shrinkage size of plastic processing is greatly affected by the molding conditions, the shrinkage rate is not a fixed value, but a range. In the specific processing process, various processing conditions can increase the molding shrinkage rate, og 4% can be selected.
For specific shrinkage, if the specific molding conditions are favorable for the reduction of molding shrinkage, then 2.5% can be selected as the specific shrinkage. Vi ved alle, at alle kunder kan lide forme med flere hulrum, the latter method is more difficult.
