注射坯成形质量与尺寸精度的控制模型

Model of Controlling Quality and Dimension of Tungsten Alloy Injected Parts

摘要:

注射坯的尺寸精度反映注射坯质量的好坏，并对控制其后脱脂和烧结过程缺陷和最终产品尺寸精度起着很关键的作用。文章基于烧结收缩各向同性的前提下，提出了通过注射坯质量偏差控制注射坯尺寸精度和注射坯质量的数学模型，并在实验中验证了这一模型的正确性。

Abstract:

Dimension of injected parts reflects the quality of injection molded parts, and plays an important role in controlling defects and final dimension of parts during subsequent debonding and sintering. On the premise of same shrinkage in different directions during sintering, a mathematic model of controlling injected parts dimension and qualities by controlling the weight deviations of injected green parts, which is proved to be correct in the experiment is proposed.
