PP Sheet has many advantages and disadvantages, and it has a wide range of applications. It is suitable for packaging, automotive, consumer goods, medical, cast films, etc.

2. Shrinkage Deformation Problem and Solution of PP Sheet

Shrinkage deformation is the phenomenon that the PP sheet product surface appears concave marks or dents due to the shrinkage of the material during cooling and solidification. It affects the appearance and performance of the product.
The main causes of shrinkage deformation are the high shrinkage rate of PP material, the uneven wall thickness of the product, the insufficient pressure and cooling time during molding, etc.
The main methods to solve shrinkage deformation are to control the quality of the raw material, to design a reasonable wall thickness and round corner for the product, to increase the holding pressure and cooling time during molding, etc.

3. Dimensional Accuracy Problem and Solution of PP Sheet

Dimensional accuracy is the degree of conformity between the actual size of the product and the design size. It reflects the quality and precision of the product.
The main factors affecting dimensional accuracy are the shrinkage rate, temperature, pressure, flowability of PP material, as well as the mold design and processing accuracy.
The main methods to improve dimensional accuracy are to select a suitable shrinkage rate, temperature and pressure parameter for PP material, to use alignment tools and column tools for mold design and processing, etc.

4. Surface Treatment Problem and Solution of PP Sheet

Surface treatment is the process of modifying or enhancing the surface properties of PP sheet products, such as color, gloss, texture, adhesion, etc. It can improve the appearance and functionality of the products.
The main difficulties of surface treatment for PP sheet products are the poor printing, coding and engraving effects due to the low surface energy and polarity of PP material, as well as the poor resistance to solvents or aromatic hydrocarbons.
The main methods to improve surface treatment effects for PP sheet products are to select suitable ink or coating for PP material, to use special equipment or technology for printing, coding or engraving, to increase surface roughness or activity by corona treatment or plasma treatment, etc.
