Cold Formed Drive Shafts

Cold Formed Drive Shafts are core power transmission components in mechanical transmission systems. They transmit torque from the power end to the load end through their own torsional rigidity, and their strength and accuracy directly affect the efficiency and reliability of the transmission system. Our Cold Formed Drive Shafts are made of high-quality medium carbon structural steel as raw material and processed by cold extrusion forming process. The metal fibers are continuously distributed along the axial direction, without the fiber cutting problem of cutting processing. Compared with traditional turned drive shafts, the torsional strength is increased by more than 25%, and they can withstand larger impact torque without breaking. The shaft body has high surface smoothness and stable dimensional accuracy, and has good dynamic balance performance during rotation, which can effectively reduce transmission noise and vibration. With 18 years of experience in cold formed parts production, our products have been supplied to many overseas automotive and machinery manufacturing customers.

We can customize Cold Formed Drive Shafts with different diameters, lengths and shaft end structures according to customers' transmission torque, rotational speed, installation space and connection methods, supporting various shaft end structures such as splines, clamping grooves, flanges and threads, adapting to different connection working conditions. The product can be subsequently subjected to heat treatments such as high-frequency quenching and carburizing to further improve surface hardness and wear resistance and extend service life. Each drive shaft undergoes strict dimensional inspection, run-out test and hardness test before leaving the factory to ensure that geometric tolerance and mechanical performance all meet the standards. For overseas auto parts and construction machinery customers, we can also provide supporting services such as dynamic balance test and surface anti-corrosion treatment to meet customers' differentiated needs.

We have 2 production factories in Hangzhou and 1 cold heading factory in Ningbo, equipped with a full set of production and testing equipment such as multi-station cold extrusion machines, CNC lathes, heat treatment furnaces and dynamic balance testers, with 80 skilled production personnel and a professional R&D team, and a monthly production capacity of 60 tons of various hardware parts. We have focused on the R&D and production of non-standard metal parts for 18 years. As the foreign trade export platform under Boming Hardware, our export sales have maintained a steady growth of 38% for consecutive years. Cold formed transmission products have been supplied to many automotive parts and equipment manufacturing customers in Europe for a long time, with mature development and mass production experience.

We have established a complete industrial parts customer service system. Before sales, we can provide free product samples, material inspection reports and technical selection suggestions, and customers only need to bear the international express freight; during the production stage, we can regularly feedback production progress to customers and provide real-time production pictures and video updates; after sales, the products come with a 1-3 year warranty period. If quality problems such as breakage and deformation caused by non-human damage occur under normal installation and use conditions, we will provide replacement services for customers at the first time. We promise to respond to all after-sales inquiries within 24 hours to efficiently and quickly solve various customer problems.

We support full-process OEM/ODM customization services, and can customize drive shaft products with different structures, sizes, materials and performance according to customer-provided drawings, samples or transmission parameter requirements. The minimum order quantity for custom orders is 100 pieces, the sample development cycle is 30-45 days, samples are provided free of charge, and customers only need to bear the international express freight. Our technical team can provide material selection and structure optimization suggestions for special working conditions such as high torque and high speed, helping customers reduce the overall procurement cost while ensuring performance.
