Development of General-Purpose System for Short-Time Molding and Processing of Thermoplastic Composites

Thermosetting resin composite materials, such as epoxy resin, which have low productivity and are not suitable for mass production, are expensive and have a limited track record of use. However, in order to dramatically improve their productivity, support mass production, and reduce costs, we have jointly developed with companies and universities a process for molding thermoplastic composite materials in a short period of time.This will help to open up new markets in industrial fields that have had little experience with the use of such materials.

Main Achievements

  • Metal press manufacturers
  • Plastic molding manufacturers
  • Material manufacturers
  • Prepreg manufacturers
  • Public institutions such as industrial technology centers

System Features

システムの特徴

Existing press machines for thermosetting resin molding and metal forging press machines are easily modified and converted, enabling short-time molding of thermoplastic composites with only the introduction of a dedicated die and temperature controller.

  1. Supports both thermoplastic and thermosetting prepregs
  2. Supports cold press molding in a short time by using a near-infrared lamp heater
  3. Enables hot press molding while impregnating resin by employing a dedicated mold
  4. Equipped with 16 independent channels for stable mold temperature control
    ・Enables automatic regulation of heater and cooling water flow during heating and cooling
  5. Easy to set conditions using software developed exclusively for composite molding
    ・Large touch panel for easy viewing and improved operability
    ・Connecting to a PC enables management of molding conditions and data editing

Overview of Composite Material Molding

システムの特徴
  1. The molding cycle is extremely fast because the material (plate) is heated and pressed in a die at the appropriate temperature, which is ideal for large or deep products.
  2. Using rolled material makes it easy to cut and eliminates the need for trimming after molding.
  3. It is ideal for semi-prepreg molding as the material can be impregnated during molding (pressing.)
