  3. Blister products are formed by heating the sheet, then pushing the sheet out to bond the sheet to the mold by suction, and then cooling and forming.

  4. Injection molding products are usually more expensive than blister products, and their production methods are also different. It is usually made by extruding the plastic after hot-melt pressure onto the injection mold, and then cooling and forming. Usually used for mobile phone case, computer case, plastic cup, mouse case, hardware accessories case, etc. If the product has quality problems, there will be color difference, insufficient filling, welding marks, warping deformation, corrugation, etc.
  5. Blister products are a hot-soft production mode. The tribute tea cup can be made of multiple molds for multiple products at one time. The production cycle of the injection mold in the injection cup is longer, and it is produced by pressing multiple products in a single mold shape, and it does not need to be divided into punches to directly form the product. From the perspective of practical application, blister is a product in the form of packaging, while injection molding is a product in the form of articles.
