コーヨー化成 List of Products and Services

Vacuum forming is a processing technology that shapes a softened plastic sheet by pressing it against a mold using heat. It can accommodate various shapes, including parts used in the automotive and electronics industries, and is widely utilized for both small-batch custom products and large-scale production. Its advantages include low mold costs and ease of prototyping and small-scale production. At Koyo Kasei, we leverage our knowledge from fundamentals to applications to provide optimal solutions tailored to our customers' needs. If you would like more detailed information about vacuum forming or case studies, please feel free to contact us. *For more details, please refer to the PDF materials or feel free to reach out to us.*

We would like to introduce the vacuum forming method that our company employs. Vacuum forming is a process in which a heated and softened plastic sheet is placed over a mold surface, and by creating a vacuum in the gap, it adheres to the mold surface to form a shape. This shape is then cooled and solidified to obtain the final product. Compared to injection molding, it allows for quicker and more cost-effective product acquisition. 【Features】 ■ Creates shapes by adhering to the mold surface, then cools and solidifies to obtain the product ■ Allows for quicker and more cost-effective product acquisition compared to injection molding *For more details, please download the PDF or feel free to contact us.
