For OEM purchasing teams in Europe and North America, the main concern when sourcing rubber and plastic parts from China is rarely price. It is material consistency, engineering responsiveness and long-term supply security. A provincial key laboratory designation is one of the clearest answers to those concerns.
Hebei Huami New Material Technology Co., Ltd. (Beijing Stock Exchange: 920247) operates the Hebei Provincial Key Laboratory of Special Rubber and Plastic Materials and Application Research. This government-recognized platform brings special rubber formulation, engineering plastic modification and testing under one roof, giving overseas buyers verifiable technical backing for commercial vehicle rubber damping parts, rubber seals and engineering plastic components.
• Founded in 1998; listed on the Beijing Stock Exchange in 2022
• Over 20 years in special rubber and plastic materials, with more than 2,400 material formulations
• Contributor to the drafting and revision of multiple Chinese national and industry standards
• R&D team of 100+ covering formulation, structural design, process, tooling and testing
• Applications in commercial vehicles, automotive, rail, construction machinery and aerospace
Hebei Tongsource International Trade Co., Ltd. is a wholly-owned subsidiary of Hebei Huami New Material Technology Co., Ltd., dedicated to overseas sales and customer service. Through Tongsource, buyers work directly with the listed manufacturer's R&D, production and testing resources, with no layers of middlemen and one clear point of accountability.
• Special rubber formulation: NR, SBR, NBR, EPDM, FKM, silicone and more
• Compound mixing processes and batch consistency control
• Engineering plastic modification, including high-performance materials such as PEEK
• Structural design, simulation and validation of rubber and plastic parts
• Physical, chemical and simulated service-environment testing of materials and finished parts
Compounds are formulated in-house, and the process from raw material selection through mixing to vulcanization is fully controlled. Buyers receive not just a part, but a traceable material solution.
Dedicated compounds can be developed to customer drawings, OEM numbers and material specifications, matching Shore A hardness, temperature range, and oil and fluid resistance requirements.
Routine tests cover hardness, tensile strength, elongation at break, compression set, heat aging and fluid resistance, providing data for sample approval and production quality control.
Materials can be benchmarked and tested against customer-specified standards such as ASTM D2000 and ISO, reducing technical back-and-forth for European and North American customers.
Huami continues to expand capacity in special rubber materials and special engineering plastics, backing long-term, stable supply with the governance of a listed company.
It shows that the supplier's R&D system has been recognized by provincial science and technology authorities and has sustained material development and testing capability. For buyers, it is verifiable evidence of technical strength during supplier qualification.
Yes. Share your drawing, OEM number, material specification and operating conditions. The laboratory will evaluate and develop a matching compound and provide test data with the samples.
Formulations are owned in-house, mixing processes are controlled, and key properties are verified per batch through laboratory testing, reducing variation at the source.
Standard material and finished-part data include hardness, tensile strength, elongation at break, compression set, heat aging and fluid resistance. Please specify any special tests when requesting a quote.
Yes. We can benchmark and test materials against your specified international standard or OEM material specification and reference the relevant clauses in the report.
If your project requires REACH, RoHS or other environmental compliance, please state it at the inquiry stage. We will confirm against the specific compound and provide the corresponding declarations.
Parts with existing compounds and tooling sample quickly; new tooling is assessed by part complexity. Trial orders in small quantities are supported, and exact lead times and MOQs are confirmed in the quotation.
Heavy trucks, trailers, buses and construction machinery, including rubber damping parts, bushings, seals, engineering plastic parts and self-lubricating bearings.
Tongsource is Huami's wholly-owned export subsidiary. It knows European and North American requirements, Incoterms and customs procedures, and draws directly on factory R&D and production, so technical and commercial questions are handled through one channel.
The Hebei Provincial Key Laboratory of Special Rubber and Plastic Materials and Application Research is the core of Huami's technical capability. For European and North American OEMs and buyers, it means better-controlled materials, faster custom development and evidence-based quality assurance.
Contact us today: Send your OEM number, drawing or material specification, estimated annual volume and application conditions to Hebei Tongsource International Trade Co., Ltd. We will respond with a compound recommendation, samples and a formal quotation.
