Our raw material control is carefully overseen by our Chief Materials Engineer at Zebung, who brings over 30 years of expertise in the rubber industry. Supporting this, our research and development team consists of graduates from chemical engineering and materials science disciplines. We take pride in our self-sufficiency, independently researching and producing the rubber used in our hoses, ensuring adherence to rigorous testing standards, including compliance with the GMPHOM 2009 guidelines. Furthermore, our hoses are crafted from carefully selected natural rubber imported from Thailand and nitrile butadiene rubber (NBR) sourced from South Korea, chosen for their exceptional heat resistance.

Our company conducts thorough inspections of rubber hoses to uphold quality standards. This includes verifying the size, quantity, and ensuring the accuracy of the mark contents , ensuring that they align with the product specifications. Furthermore, we meticulously measure both the inner and outer diameters of rubber water hoses to detect any significant deviations, thereby ensuring precise dimensions and reliable performance. Additionally, our dedication to quality is evident in our investment of 20% of annual profits towards research and development, driving innovation and excellence in our product range

Zebung thoroughly inspects every stage of the manufacturing process, from raw rubber materials to rubber sheets, and then to the final products. Our overarching aim involves using advanced machinery to meticulously measure and monitor product quality, ensuring adherence to strict standards throughout production and beyond.
