Unsaturated polyester resin is a thermosetting resin. It is shaped by heating the mold to a high temperature and curing the resin with heat. The characteristics of unsaturated polyester resin include dimensional stability, tensile strength, flexural strength, impact resistance, electrical insulation, heat resistance (cold resistance), and excellent chemical resistance. It has contributed to solving customer challenges by replacing metal components with resin or substituting parts that cannot meet physical properties with unsaturated polyester resin. As an example of our achievements, we have successfully integrated molding (insert molding) with thin glass. Our company specializes in precision molding and insert molding of unsaturated polyester resin, responding to various customer requests based on the BMC molding technology and experience we have accumulated over many years. *For more details, please refer to the PDF materials or feel free to contact us.

• Resin processing machine

There are many achievements in super engineering plastics such as PEEK (polyether ether ketone), PPS (polyphenylene sulfide), PEI (polyether imide), PES (polyether sulfone), and LCP (liquid crystal polymer). High-performance resins classified as super engineering plastics have higher molding temperatures and mold temperatures compared to general plastics, requiring optimal molding equipment, mold design, and molding know-how. Based on the achievements and experience we have cultivated so far, we will respond to our customers' requests. For more details, please refer to the PDF materials or feel free to contact us.

• Engineering Plastics

Polyether ether ketone (PEEK) is a thermoplastic resin classified as a super engineering plastic that is difficult to mold. Its characteristics include a high heat resistance (continuous use temperature of 260°C), excellent mechanical strength, wear resistance, sliding properties, chemical resistance, and radiation resistance, with low leachables such as ions and outgassing, making it biocompatible. Additionally, it has recently gained attention as an alternative to fluoropolymers in terms of chemical resistance. However, while the molding temperatures for general plastics range from 200 to 300°C, PEEK resin requires a high temperature of 400°C, and the mold temperature must also be set around 200°C, necessitating very high temperatures for molding. Molding at high temperatures can lead to significant variations in quality, requiring specialized know-how. Our company can achieve stable molding through optimal molding equipment and mold design based on our extensive experience with PEEK resin, as well as material selection tailored to customer requirements. *For more details, please refer to the PDF document or feel free to contact us.*
