Alignment Feature: Tolerance ±0.002 mm to ±0.01 mm

Component Specifications

Definition

A critical precision component integrated into mold core inserts that provides mechanical reference points and mating surfaces to ensure exact alignment and positioning within precision casting molds. These features maintain dimensional accuracy, prevent misalignment during assembly and operation, and ensure consistent part quality in high-precision casting applications.

Working Principle

Utilizes precisely machined geometric features (dowels, slots, pins, or mating surfaces) that engage with corresponding features on mold plates or other inserts. These features create positive mechanical stops and reference points that eliminate positional ambiguity during assembly, ensuring repeatable alignment to within tight tolerances.

Materials

Typically manufactured from high-grade tool steels (AISI D2, H13, or S7), carbide, or hardened stainless steel. Materials are selected for dimensional stability, wear resistance, and compatibility with casting temperatures and environments.

Frequently Asked Questions

What types of alignment features are most common in precision casting molds?

Dowel pins and bushings, tapered locating pins, precision ground slots, and mating shoulder surfaces are the most common alignment features, selected based on mold complexity and precision requirements.

How do alignment features affect casting part quality?

Proper alignment prevents flash formation, ensures uniform wall thickness, maintains dimensional accuracy, and reduces scrap rates by eliminating misalignment-related defects in cast parts.
