Instructions for Castings Drawings for the Semiconductor Industry | Prevention of Oversight in Ordering Instructions
Eliminate insufficient accuracy and rework to zero. From dimensional tolerances to inspection items, professionals explain the essential points of "casting drawings" that young designers and purchasing staff should grasp.
When ordering precision parts for semiconductor manufacturing equipment in cast materials, are you facing issues such as "insufficient finishing accuracy" or "warping after processing"? We will explain the drawing and ordering points to prevent these problems. ■ Important Instruction Items Often Overlooked Processing Reference Surface: Clearly specify whether it is a cast surface or a machined surface, and any constraints on draft angles. A "casting reference" is essential to prevent misalignment. Heat Treatment: Clearly state the heat treatment conditions to suppress processing distortion caused by residual stress. Material Specifications: If applying special materials other than JIS standard materials, specify the necessary physical properties. Performance Guarantee: If important material properties such as the coefficient of linear expansion are required, indicate whether a guarantee through analysis is necessary. ■ Practical Checklist 1. Is the allowable range for draft angles clearly defined? 2. Is the processing allowance appropriate (consideration of cost reduction through near-net shape)? 3. Are there standards for appearance quality and inspection items (such as non-destructive testing)? The Hinode Group provides comprehensive support from material development to precision processing, assisting in high-quality, low-cost procurement through optimal manufacturing method considerations from the drawing stage.
