Precision cast plastic parts find applications across a range of sectors

(5) The effect of shell baking: Because the expansion coefficient of the shell is small, when the shell temperature is 1150℃, it is only 0.053%, so it can be ignored.

Benefits of Copper Stamped Parts

2. Pattern Removal Once the sand is compacted, the pattern is removed, leaving a hollow cavity. The mold is then assembled, and any additional features such as cores or risers are added to control the flow of molten metal.

The draft angle is the taper added to the mold walls of a die cast. It allows for the easy removal of the finished part from the mold without causing damage. When a cast part is produced, it tends to shrink slightly as it cools. If the mold is perfectly vertical with no draft angle, the part may become stuck, leading to potential defects and damage during extraction. The draft angle facilitates smooth ejection, ensuring that the part can slide out without hindrance.
