XIAMEN KEHENGPLASTIC CO.,LTD

Xiamen Keheng Plastic Co., Ltd. is located in Xiamen, China. After years of development, the company has grown into a large comprehensive enterprise integrating mold design and development with the production and sales of plastic products. Upholding the corporate spirit of “people-oriented and integrity-based,” Keheng has gradually become a highly cohesive, competitive, and creative enterprise team. Our WF trademark is derived from the English words “Wonderful Future,” meaning “a bright future.” The company’s main products include various industrial pipelines and fittings made of UPVC, CPVC, PPH, and PVDF, double-union ball valves, single/double-union check valves, single/double-union foot valves, butterfly valves, flanged ball valves, flanged check valves, flanged foot valves, electric/pneumatic ball valves, electric/pneumatic butterfly valves, Y-strainers, and other products. These products are widely used in many industries, including chemical engineering, wastewater and sewage treatment, power plant construction, PCB production lines, strong acid and alkali industries, and water purification projects. Quality is the lifeblood of our products. All raw materials and components purchased by the company must first pass strict incoming inspections before being stored. After each process is completed, quality inspectors strictly inspect the products, and only qualified products may proceed to the next process. This rigorous approach ensures that every product leaving the factory is qualified. Through the efforts of all employees, the company successfully passed ISO9001:2008 quality management system certification in 2011 and has successively obtained product quality inspection reports from the National Plastic Products Quality Supervision and Inspection Center and SGS. With excellence in quality and attentive customer service, Keheng’s products have established a good reputation in the market and have won the recognition and trust of customers for their excellent and stable quality. With Xiamen as the center, the company’s sales network extends to more than 20 provinces, municipalities, and autonomous regions across China, as well as Europe, the United States, and Southeast Asian countries. The products manufactured by Xiamen Keheng Plastic Co., Ltd. have the following advantages: 1. All product molds are independently developed and designed by our R&D personnel, ensuring that each mold achieves optimal performance during production. 2. Molds of any required specification can be tailor-made according to customers’ requirements or samples, helping customers save time in new product development. 3. All processing aids, stabilizers, and other materials required for the company’s material formulations are imported to ensure product quality. 4. The company has consistently used fixed suppliers and fixed-grade raw materials for many years, ensuring the stability of the color, appearance, and performance of each batch of products. 5. All double-union ball valve bodies are processed and formed using advanced CNC machine tools to ensure product accuracy. 6. The assembly holes for all double-union ball valve bodies and valve stems are precision-machined using advanced boring machines to ensure sealing performance. 7. Each ball of every ball valve is first turned on a CNC machine tool to control its roundness within 0.05 mm, and then ground with advanced grinding machines to ensure smooth opening and closing without excessive effort and to prevent leakage. 8. Each sealing ring of every ball valve is turned and polished according to the roundness of the ball, ensuring a tight fit with the ball, extending service life, and ensuring sealing performance. 9. The flat-bearing part of each product is machined using advanced CNC lathes to ensure a tight fit between the flat bearing and the O-ring. 10. All valve products undergo 100% air-tightness testing during production to ensure that every product leaving the factory is qualified. “Teamwork, integrity, excellence, and gratitude” are Keheng’s business philosophy. New opportunities, new challenges, and a new journey. Facing the severe challenges of the pipeline industry, we continuously introduce new technologies, develop new products, innovate constantly, and improve and surpass ourselves. With the spirit of self-improvement and unremitting effort, we are advancing toward becoming a world-class enterprise.
