The production process of vacuum packaging mainly includes steps such as material selection, mold design, heating, suction, cooling, cutting, edge sealing, etc. The influencing factors in the production process mainly include the following points:
Material selection: The selection of vacuum forming materials has a significant impact on product quality and cost. The physical, chemical, and processing properties of different materials can all affect production efficiency.
Mold design: The design of the mold directly affects the shape, size, and surface smoothness of the vacuum molded product. Excellent mold design can reduce waste and improve production efficiency.
Heating temperature and time: Heating temperature and time are one of the key factors affecting the quality of vacuum molded products, and need to be adjusted appropriately according to the characteristics of the material and the shape of the mold.
Inhalation time and pressure: The magnitude of inhalation time and pressure can affect the shape and sealing of vacuum molded products. Reasonable suction time and pressure can ensure the accuracy and sealing of product shape.
Cooling time and method: The choice of cooling time and method can also affect the quality and cost of vacuum molded products. Reasonable cooling time and method can reduce problems such as deformation and residual stress.
