• About Us

CYK Group

Established in 1994, Chiao Kai Industrial Co., Ltd. (CYK) specializes in the development and manufacturing of cleanroom and sterile protective garments. With over two decades of industry experience, we proudly deliver stable, high-quality products under our CYK brand, building long-term partnerships with clients across a wide range of industries.

As one of the few vertically integrated manufacturers in Taiwan, we offer full-spectrum capabilities spanning design, production, and marketing. Our product range includes cleanroom garments, shoes, caps, and sterile suits suitable for Class 10–100 and Class 100–1000 environments — serving the needs of industries with demanding contamination control requirements.

  • Custom Solutions

    In recent years, industries such as electronics, semiconductors, and biotechnology have placed growing importance on electrostatic discharge (ESD) control and particle contamination prevention. CYK offers customizable cleanroom garments — including coveralls, hoods, and shoes — tailored to various cleanroom classifications and client-specific requirements.

    Our products are designed to meet the specialized needs of a wide range of industries, including photomask manufacturing, wafer foundries, semiconductors, IC design, chip packaging and testing, PCB, LED, LCD, OLED, TFT/LCD, smartphones, notebooks, PCs, as well as active and passive electronic components.

  • Production Advantages

    By combining Taiwan’s advanced technical expertise with the cost-efficient production capacity in China, CYK manufactures cleanroom garments and footwear that exceed both Federal Standard 209E and ISO 14644 requirements. We utilize premium cleanroom fabrics sourced from the U.S., Japan, and China, achieving ANSI/ESD S20.20 compliance with surface resistance as low as 3.5×10⁷ Ω.

    CYK continues to improve quality and customization efficiency, and to date, we have earned the trust of over 1,000 clients across various industries.

    CYK is headquartered in Kaohsiung, Taiwan, with branch offices in Hsinchu, Taichung, and Suzhou (China), along with a sales office in Dongguan. To expand our service reach, we are continuously establishing new business locations across Asia and around the world, moving steadily toward becoming a diversified and international enterprise.
