Dowel Pin Manufacturing Process
Precision Cutting & Blanking
High-precision CNC cutting for exact sizing, ensuring uniform raw blank dimensions.
Outer Diameter Rough Grinding
Pre-grinding phase leaving tight stock allowances to prepare for high-precision fine grinding.
End Chamfering & Turning
Removes end-face burrs and machines smooth lead-in chamfers for seamless assembly.
Heat Treatment
Quenching refines microstructure and increases hardness; tempering relieves internal stress for durability.
Precision Fine Grinding
Ensures exact outer diameter dimensional tolerances and superior surface roughness (Ra) standards.
Surface Polishing
Utilizes premium abrasives and compounds to eliminate minor surface imperfections and burrs.
Anti-Rust Coating
Applies specified rust-preventative oils followed by centrifugal spin-drying for a clean coating.
Sorting & Quality Inspection
100% visual sorting prior to packaging; stringent GP12 containment inspection available upon request.
Dowel Pin Inspection and Testing Capabilities
As a precision dowel pins supplier, Anhui Pins inspects pin diameter, length, profile, and critical dimensions according to applicable standards or customer drawings to meet specified tolerances and pin-to-hole fit requirements.
Dimensional and Profile Inspection
Digital micrometers, optical projectors, and automated vision measuring systems are used to inspect dowel pin diameter, length, profile, and other critical dimensions. Measurements are checked against applicable standards or customer drawings to verify dimensional compliance.
Roundness and Surface Roughness Testing
Roundness measurement and surface roughness testing help assess cylindrical geometry and surface finish. These checks support dimensional consistency and fit requirements in precision assemblies, particularly where close-fitting dowel pins are specified.
Material Composition Verification
Spectrometric analysis of incoming raw materials helps verify metal composition against the specified material grade. Material inspection records can support incoming material control and batch traceability throughout the manufacturing process.
Hardness and Metallographic Inspection
Rockwell and Vickers hardness testing evaluate hardness against specified material and heat-treatment requirements. Metallographic examination can be performed when required to assess material microstructure and support analysis of heat-treated components.
Pin Shear Strength Testing
Pin shear testing evaluates the resistance of applicable dowel pins to transverse loading under defined test conditions. Test results can be used to assess shear performance against specified technical requirements for mechanical locating and fastening applications.
Mechanical Performance Testing
Tensile and fatigue testing can be applied where required by the product specification or engineering application. Defined test methods and loading conditions help evaluate relevant mechanical properties and performance requirements for selected pin products.
