Junma provide the best solution for the glabal customers with static sealing technology
Established in June 1997, Chengdu Junma Sealing Technology Co., Ltd. is recognized as a state-level high-tech enterprise. The company is dedicated to the research, development, production, and sales of static sealing materials and friction materials of the highest quality. Over nearly three decades, Junma has consistently focused on technological advancement and the continual refinement of its manufacturing processes, ensuring that its sealing materials remain superior in performance.
Junma’s commitment to independent research and development, coupled with the adoption and integration of advanced international technological expertise, has positioned the company as a leader within the Chinese sealing material industry. Its unique asbestos-free Beater-Addition materials are acclaimed for their exceptional sealing properties and wide applications. Junma’s products not only compare favorably with, but often surpass, many imported sealing solutions available on the market.
Junma is a company fully committed to Sealing Technology. While manufacturers worldwide have slowed down on research and development of sealing materials, Junma still continue in spending 8-10% of company’s revenue in developing innovative manufacturing process and high performance sealing products. The results have helped Junma generating 30 proprietary patents and leading Chian in product quality and performance. Junma plays an active role in the sealing industry in China. The company not only serves as a board member of the China Sealing Materials Association, it also is a senior consultant of the Standardization Committee for Non-Metallic Mineral Products and their Products. In addition, Junma has also made significant contributions to the development of more than 20 national industry standards for sealing materials and non-metallic products in China.
Quality Management
Management System:Junma company complies with the IATF 16949:2016, ISO 9001:2015, and ISO 4001:2015 management systems, as well as the ISO 5001:2018 energy management system.
Quality certification: All of Junma products are subjected to annual testing to ensure compliance with toxic chemical content regulations. They consistently meet the requirements outlined in the ROHS and REACH EU Directives for hazardous materials.
Technological Capabilities and Product Features
The company employs innovatve in-situ nano-particle generating techniqes, raw material surface modification techniques, and co-precipitaion techniqes during the manufacturing of its sealing products. This approach results in a tightly bound material structure, which delivers excellent mechanical property and sealing performance of Junma’s sealing products. Junma’s sealing products are specifically engineered to perform effectively under demanding conditions, including high temperatures, significant pressure differences, high humidity, intense friction, frequent vibrations, and exposure to aggressive chemical reactions. These materials exhibit integrity, strength, resistance to pressure and temperature, and strong corrosion resistance, making them suitable for use in both acidic and alkaline environments.
Junma is capable of designing products tailored to customer specifications, offering materials with variable compression and recovery characteristics, back elastic energy, insulation properties, flame retardance, electromagnetic shielding, and thermal conductivity. The company’s products are environmentally friendly and pollution-free, providing a reliable alternative to high-end imported friction and sealing materials.
Industry Applications
Junma’s products are widely used in a range of industries, including automotive, motorcycle, small engines, shipbuilding, petrochemicals, refrigeration compressors, and nuclear power generation industry. The company’s wet-processed friction materials have demonstrated outstanding properties, outperforming other domestic products and matching the quality of advanced imported materials. As a result, these products are well suited to replace high-end imported materials commonly required in the sealing industry.
