What Are The Common Quality Problems Encountered With Unqualified Vacuum Formed Products?

The vacuum forming industry is an emerging plastic processing industry, and there is no professional technical standard yet, so there is no universal standard to measure whether products are qualified. As a convention, the final bulk sample provided to the customer shall prevail. If it differs from the sample in terms of aesthetics and functionality, such as transparency, surface smoothness, flatness, and cleanliness, the aesthetics may deteriorate; Products that fail to meet functional requirements, such as hardness, loosening or shrinking of acupoints, are defined as unqualified vacuum formed products.
