Stainless Steel Dowel Pins

Stainless Steel Dowel Pins are basic components for precise positioning in molds, tooling and precision equipment. Through precise interference fit with pin holes, they realize precise positioning between two or more components, ensuring assembly position accuracy and repeat positioning accuracy. Our Stainless Steel Dowel Pins are made of 304 or 316 high-quality stainless steel bars as raw materials, and are formed by precision centerless grinding and end face chamfering. They have high cylindricity, dimensional accuracy up to micron level, smooth and burr-free surface, and at the same time have excellent corrosion resistance and shear strength, adapting to various use environments such as outdoor, humid and clean rooms.

 

We can provide various types of Stainless Steel Dowel Pins such as cylindrical pins, internal thread cylindrical pins, taper pins and spring pins, covering common specifications from Φ1mm to Φ20mm, and support customization of non-standard length, special tolerance and special structure dowel pins. The product can be polished, passivated and other surface treatments according to needs to further improve surface quality and anti-corrosion performance. 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. For overseas mold and automation equipment customers, our high-precision dowel pins can directly replace similar imported products, greatly reducing customers' procurement costs.

• Template precise positioning of stamping dies and injection molds
• Component positioning and assembly of tooling fixtures and gauges
• Structural positioning of automation equipment and precision instruments
• Precision assembly of aerospace and electronic equipment
• Positioning connection of mechanical parts and gearboxes

We support full-process OEM/ODM customization services, and can customize 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 centerless grinders, precision lathes, heat treatment equipment and 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 highly recognized quality.

Our stainless steel dowel pins adopt precision 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.
