Product Description

Function and Types

The dowel pin serves to position and fasten mechanical parts, available in cylindrical and conical types. Installation typically uses pressing methods or soft metal knocking techniques. These small, usually conical or cylindrical metal pieces are essential for fastening components in various applications.

Pins are crucial in mechanical connections and come in several types including cotter pins, conical pins, cylindrical pins, and slot pins. Among these, cylindrical pins, conical pins, and cotter pins are the most widely produced commercial fasteners.

Applications

Industry	Usage
Automotive	High-strength applications like engines and heavy-duty machinery
Mechanical	Connecting parts in machinery, electronics, and construction
Energy	Connecting power generation equipment and transmission lines
Architectural	Building structures, shipbuilding, and petrochemical equipment

Material Specifications

Material	Characteristics
Aluminum	Excellent thermal/electrical conductivity but soft, requires careful processing
Titanium	Requires EDM machining with deionized water to control heat
Steel	Very strong, often requires wire cutting for complex features
Brass	High tensile strength but requires slow cutting speeds

Features and Advantages

Appearance: Smooth surface with anti-rust coating, chamfered edges without burrs
Dimensions: Precisely manufactured to specifications
Surface Roughness: ≤ 3.2 roughness standard
Hardness: Meets specified requirements
