Preparation of a Clamp Sleeve Spare Parts for Crimping Machine Using Low Carbon Steel Material by Heat Treatment Process

In Metered Dose Inhaler plant of pharmaceutical industries of Bangladesh, clamp sleeve spare part used in crimping machine collected from foreign countries. The clamp sleeve presses the crimping tong containing aluminium can to crimp the body with head. Due to the continuous action of the clamp sleeve to the crimping tong the inner surface of the clamp sleeve get corroded. The clamp sleeve is replaced when crimping appearance fails to meet compliance. In this Research an experimental work relating to improve the mechanical properties of locally available low carbon steel material by heat treatment process have been carried out to replace the spare parts of clamp sleeve which is collected from foreign countries. The mechanical properties have been studied on before and after heat treatment. After heat treatment, it is found that hardness, impact and compressive strength of heat treated specimen has been developed drastically as compared to that of before heat treatment. Finally, the properties of improved material has been determined and used to the machine functional area to check the performance of the clamp sleeve. After consecutive operation of the machine it can be concluded that the improved clamp sleeve meets the user requirement with compliance of smooth crimping quality and locally available low carbon steel material can be used for the preparation of clamp sleeve spare parts of crimping machine for pharmaceutical industry using the proper heat treatment process which might be helpful to save huge cost and time rather than collected from foreign countries.
