Pin Body Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

The pin body is a critical component of venting pins used in precision casting molds, designed to create controlled pathways for air and gases to escape during molten metal injection. This prevents defects like porosity, incomplete filling, and surface imperfections by ensuring proper cavity evacuation and pressure equalization.

Working Principle

The pin body functions as the structural core of venting pins, maintaining dimensional stability while allowing gases to pass through micro-channels or porous structures. During casting, thermal expansion creates precise gaps between the pin body and mold, facilitating controlled venting without metal leakage.

Materials

High-temperature tool steel (H13, A2), tungsten carbide, or ceramic composites with heat resistance above 1000°C and minimal thermal expansion.

Technical Parameters

Length 20-150 mm
Diameter 1-10 mm
Hardness 45-62 HRC
Surface Finish Ra 0.4 μm max
Pressure Rating Up to 150 bar
Operating Temperature Up to 1200°C

Standards

ISO 9001, DIN 8580
