Cold Heading Dowel Pins

Cold Heading Dowel Pins are fasteners used for precise component assembly positioning. They are formed at one time by cold heading process, with high dimensional accuracy, good surface quality and high shear strength. They are basic components for achieving precise positioning in molds, tooling and automation equipment. Our Cold Heading Dowel Pins are made of high-quality carbon steel or bearing steel as raw material, and are formed at high speed by multi-station cold heading machines. They have high forming efficiency and good dimensional consistency. The cylindricity and surface smoothness are far better than ordinary turned pins. Both ends of the pins are provided with guide chamfers for convenient installation, which can realize interference fit positioning with high positioning accuracy and strong shear resistance, and can withstand transverse load without displacement. As a source factory with 18 years of experience in cold heading fastener production, our products have been supplied in bulk to overseas mold and automation equipment customers, and have been highly recognized for their stable accuracy.

We can provide various types of Cold Heading Dowel Pins such as cylindrical pins, internal thread pins, shoulder pins and taper pins, covering common specifications from Φ2mm to Φ25mm, and support customization of non-standard length, special tolerance and special structure dowel pins. The product can be subjected to heat treatments such as quenching and carburizing to improve hardness, and can also be subjected to surface anti-corrosion treatments such as galvanizing, blackening and passivation to adapt to different use environments. Each dowel pin undergoes strict outer diameter inspection, cylindricity inspection and length inspection before leaving the factory to ensure that dimensional accuracy and geometric tolerance all meet the standards, and the interchangeability of products in the same batch is consistent. For overseas precision manufacturing customers, our high-precision dowel pins can directly replace similar imported products, greatly reducing customers' procurement costs.

We support full-process OEM/ODM customization services, and can customize cold heading dowel pin products with different sizes, accuracy, materials and structures according to customers' positioning accuracy requirements, installation working conditions and base materials. 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 process optimization suggestions for special needs such as high load and high precision, helping customers improve assembly accuracy and product reliability.

We have 2 production bases in Hangzhou and 1 cold heading factory in Ningbo, equipped with a full set of production and testing equipment such as multi-station high-speed cold heading machines, centerless grinders, heat treatment furnaces and precision testing instruments, with 80 skilled production personnel and an exclusive 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. Precision positioning parts have been supplied to many overseas mold and automation equipment customers, with mature mass production experience.

Our cold heading dowel pins adopt precision protection packaging, and are sub-packaged in quantitative amounts with sealed plastic bags according to specifications to avoid bumps and scratches during transportation that affect accuracy. The outer layer is reinforced with high-strength hard cartons and wooden pallets as a whole, fully adapting to ocean transportation and multiple transshipment loading and unloading. We support FOB Shanghai port trade terms, and can assist customers in connecting with high-quality freight forwarders. The delivery cycle for both standard orders and custom orders is 30-45 days. For small-batch urgent orders, production can be arranged preferentially to fully ensure the delivery cycle.
