大成工業 List of Products and Services

We would like to introduce our technologies, "Vacuum Forming" and "Pressure Forming." "Vacuum Forming" is a molding method that uses air pressure to stretch a heated and softened plastic sheet and make it adhere closely to a mold. It is suitable for small-batch production of various types, and for example, egg cartons around us are made using this molding method. "Pressure Forming" is a method of thermal forming of sheets. After heating and softening a thermoplastic resin sheet, it is sandwiched between a lower mold and an upper pressure box, pressed to adhere to the mold, and after cooling, air is blown in to remove the formed product. It has the advantage of achieving higher pressure compared to "Vacuum Forming." We can accommodate both methods, so please consult us first. 【Features of Vacuum Forming】 ■ Low cost as it only requires a mold that is either concave or convex ■ The time-consuming process for delivery of formed products is the mold manufacturing period, but the period for vacuum forming molds is shorter ■ Since the surface does not adhere to the mold, soft shapes with curves can be created, which is effective for transparent products *For more details, please refer to the related links or feel free to contact us.
