Temperature Defects on Compressor Housing Die Casting Method

Study of Process Parameters of Gravity Die Casting Defects

In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manu...

Automatic Detection Method for Casting Defects Based on Gradient Features

In this paper, we propose an automated visual inspection method for casting defects. Automatic inspection systems have the potential to significantly improve quality and increase production rates. In our method, the contour discontinuity of casting product and machine-learning-based defect detection are utilized to detect defects on the surface of products. The peripheral vision and involuntary...

Materials on Dies for Pressure Die Casting

In the contribution the stress of die materials of thermal fatigue is defi ned and material life is derived theoretically and compared with the measured values. The important properties of the die materials as thermal conductivity, coeffi cient of thermal expansivity, modulus of elasticity and mechanical properties are described. Binding to it single die materials as carbon steels and chrome-tu...

Die Steels and Improved Productivity in Die Casting

Computer-Aided System for Multi-Cavity Die-Casting Die-Design

Die-design for the die-casting process is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, delivery time and cost preferences, etc. Complexity of the die-design activity further increases in case of a multi-cavity die. Currently available die-design systems lack in the l...
