Ideal for applications where appearance is important! Due to the absence of mold marks, there is a high demand for transparency.
Free-blow molding is a method that inflates a softened material using air after heating. A benefit is that the spherical part does not come into contact with the mold, so there are no mold marks. Because there are no mold marks, there is a high demand for transparency, and materials with high transparency, such as acrylic and polycarbonate, are often used. Additionally, since the material is heated and softened before being stretched with air, the center part becomes particularly thin. While this varies depending on the type of resin, thickness, diameter, and height, the apex of the dome, which becomes especially thin, is about half the thickness of the sheet. 【Molding Process】 1. Heat the material to soften it 2. Clamp and send air 3. Inflate with air 4. Trim after cooling *For more details, please refer to the related links or feel free to contact us.

Company information
Since its establishment in 1975 in Toyama City, Toyama Prefecture, we have been engaged in consistent production from processing to assembly using plastic sheets (boards) as raw materials. The production using plastic sheets is suitable for small to medium-sized, diverse production or prototypes, and is utilized in various fields such as the interiors and exteriors of large vehicles and special vehicles, production equipment in high-tech fields, parts for machine tools, medical device components, aircraft parts, fixtures for commercial facilities, displays for museums, and building materials for exteriors. We mainly use acrylic, PVC, polycarbonate, PET, PP, PE, ABS, AES, and artificial marble. We primarily perform vacuum forming, pressure forming, R bending, adhesive welding, NC processing, and polishing with the above resins. Among these, we have focused on thermal processing since our founding. Thermal processing methods such as R bending and vacuum forming require not only equipment but also experience and intuition. In particular, R bending of transparent materials like polycarbonate has received high praise from many clients. Additionally, our vacuum forming is suitable for large items and small lot production of diverse products due to its single-shot forming capability. In our daily production, we always maintain a commitment and theme, continuously striving for improvement and enhancing our vacuum forming technology without being satisfied with the current state.
