The "Injection Blow Molding Method" is a core technology of Wiston that allows for clean, safe, and cost-effective mass production. Since the entire process from raw materials to parison and blow molding is completed in one stage, it is easy to manage hygiene. During the molding process, the product's mouth is oriented sideways, preventing contamination from falling objects, and there is no post-processing after molding, eliminating contamination from cutting and dust. Additionally, because it uses the hot parison method, issues such as pinholes and poor adhesion do not occur, resulting in safe products. 【Features】 ■ Molding machine suitable for maintaining cleanliness ■ High airtightness and precision ■ Continuous transition from small-scale to mass production ■ Significant advantages for new product development ■ No seams, pinholes, or adhesion failures For more details, please feel free to contact us.
