In our Dandong Foundry, we use gray cast iron HT200 to produce the stove caps for cast iron gas stove burners.
These gray cast iron end caps have the advantages of easy casting, good vibration damping, strong wear resistance and good cutting ability.
The quality inspector of our foundry usually use the screw gauge to check whether the thread of the cast iron end cap is qualified.
No blow-hole is allowed in the thread of the cast iron end cap. The inner side of the cast iron end cap should have no defect, otherwise its strength will be affected.
