摘　　要：浇注件生产过程复杂,工艺控制困难。浇注件的生产过程容易出现气泡、开裂、缺陷、玻璃化温度不合格等质量问题。本文就产生这些质量问题的原因一一进行阐述。在实际生产中,要选择合适的原材料,配合较优的浇注件、嵌件、模具设计,严格进行工艺控制,合理进行装脱模操作,保证浇注件的各项性能指标都能满足要求。The production process of the casting is complicated and the process control is difficult. The production process of castings is prone to quality problems such as bubbles, cracks, defects, and unqualified glass transition temperature. This paper explains the reasons for these quality problems one by one. In actual production, it is necessary to select appropriate raw materials, cooperate with better pouring parts, inserts, and mold designs, strictly control the process, and perform reasonable assembly and demolding operations to ensure that the performance indicators of the pouring parts meet the requirements.
