In the high-stakes world of automotive and industrial machinery, the clutch spring serves as the heartbeat of the transmission system. Whether it is a clutch diaphragm spring providing the clamping force in a heavy-duty truck or a clutch coil spring dampening vibrations in a tractor, the quality of these components dictates the longevity and efficiency of the entire drivetrain. As the global industrial sector pivots toward higher performance and greater reliability, the demand for precision-manufactured clutch springs has reached an all-time high.
Today, the commercial vehicle market—encompassing trucks, buses, and agricultural machinery—requires clutch systems that can withstand extreme thermal stress and mechanical fatigue. This is where China's manufacturing prowess comes into play. By integrating advanced metallurgy with high-speed CNC production, Chinese factories have transitioned from low-cost providers to global leaders in high-specification automotive components.
Precision-engineered components for European, Japanese, and Russian truck series.
At Zhejiang TVC Auto Co., Ltd., we understand that a clutch spring is more than just a piece of coiled steel. It is a safety-critical component. Our team is led by renowned experts and senior engineers specializing in clutch manufacturing. By strictly adhering to the ISO/IATF16949: 2016 quality control system, we ensure that every diaphragm spring leaving our factory meets the rigorous demands of global procurement teams.
Our commitment to E-E-A-T principles (Experience, Expertise, Authoritativeness, and Trustworthiness) is reflected in our 90% in-house production rate. This allows us to control the entire supply chain, from raw material selection—using premium 51CrV4 and 50CrV4 steel—to the final automated pressure testing.
Transitioning from standard carbon steel to High-Stress Chrome Vanadium alloys. This ensures higher fatigue resistance and the ability to maintain clamping force even at elevated operating temperatures common in long-haul trucking.
While EVs reduce traditional clutch needs, the Hybrid Heavy-Duty segment is growing. Our R&D team is already developing specialized springs for hybrid disconnect clutches and vibration dampers used in modern powertrains.
Modern procurement demands "Zero Defect" reliability. We implement automated laser measurement and 100% load testing for every diaphragm spring to ensure consistency across large-scale batches.
Zhejiang TVC Auto Co., Ltd. was established to become an independent, specialized company focused on manufacturing clutch parts. After more than ten years of continuous effort, the company has grown into a significant player in the industry. Led by renowned experts, researchers, and senior engineers in clutch manufacturing, we take responsibility for technology, quality management, product development, and sales. Our management team, with expertise in manufacturing, production, logistics, procurement, and equipment management, has built three major product lines (light, medium, and heavy) covering a wide range of products.
Zhejiang TVC Auto Co., Ltd. specializes in the research, development, production, and sales of clutches for light, medium, and heavy trucks.
