Common problems and solutions for PET sheet blister

1. Adhesion problem on the mold surface: During the PET blister process, adhesion may occur on the mold surface, causing the product to be unable to be demoulded smoothly. The solution is to apply a layer of anti-sticking agent on the surface of the mold to reduce the occurrence of adhesion.

2. PET sheet deformation problem: PET sheets are prone to deformation during the heating process, resulting in inaccurate product shapes. The solution is to control the heating temperature and time during the heating process to avoid deformation of the PET sheet caused by overheating.

3. Surface cracking problem of PET blister products: Surface cracking of PET blister products may occur during the cooling process, which affects the aesthetics and service life of the product. The solution is to control the cooling rate during the cooling process to avoid cracking due to large temperature differences caused by rapid cooling.

4. The problem of inconsistent sizes of PET blister products: There may be certain errors in the size of PET blister products, resulting in inability to meet design requirements. The solution is to strictly control the dimensional accuracy when making molds to ensure the accuracy of mold making.
