Reasons of Workpieces Treated by Through-type Shot Blasting Machine Can Extend Their Service Life

Workpieces cleaned by a through-type shot blasting machine

The cleaning process of through-type shot blasting is a cold treatment process, in which an electric motor drives the shot blaster to continuously strike the surface of the workpiece with countless small circles of media called steel shot. Each steel shot hitting the metal workpiece is like a miniature hammer pounding the surface, pounding out small dents or depressions. To form the depression, the metal surface layer must undergo tension. Under the surface layer, compressed grains try to restore the surface to its original shape, producing a semi-sphere under high compressive force, and countless overlapping depressions form a uniform residual stress layer, further enhancing the surface hardness and fatigue strength of the workpiece, significantly extending the service life of the workpiece.

The strength of the workpiece is an important factor determining the quality of the workpiece. Therefore, if the strength of a workpiece is not enough, the quality of the workpiece is naturally not good and unqualified. This shot blasting machine can not only clean the surface of the workpiece, but also improve the strength of the workpiece by restructuring its structure, making all aspects of the workpiece strengthened. This is also an important role of the through-type shot blasting machine, which can attract a large number of consumers and is one of the reasons why it is widely used.

In general, the through-type shot blasting machine is mainly used for surface cleaning of some cast steel and cast iron parts, because many cast steel and cast iron parts have many oxide scales and sticky sand on the surface when they are just completed. If shot blasting treatment is not performed, these objects do not meet the standards and cannot enter the market. Therefore, it is important to perform shot blasting treatment on them. At this time, the through-type shot blasting machine can play its role and clean the sticky sand and oxide scales on the surface of the cast steel and cast iron parts.

Storage of the through-type shot blasting machine

The through-type shot blasting machine should be placed in a workshop that is protected from rain and dryness, to avoid damage to electrical components and rust and agglomeration of shot. If the dust removal system equipped by the user has no special requirements, it can be placed outdoors. If the user plans to place the through-type shot blasting machine outside the workshop, a simple workshop should be specially designed for the equipment to protect the through-type shot blasting machine; at the same time, the convenience of equipment maintenance and transportation of workpieces, the impact of the surrounding environment on the surrounding environment, and other factors should be considered, so that this equipment can better serve users. The through-type shot blasting machine needs to meet environmental protection requirements, specifically speaking, the through-type shot blasting machine filter material should be of good quality and will not cause environmental pollution, and the dust removal system can operate normally and stably.
