Weight, cast iron weight, weight manufacturer - how to properly handle the surface Shanghai Jiujin Weighing Apparatus Factory - Weight, cast iron weight processing surface is what we often say polished! So how do we properly polish and finish the smoothness of our cast iron weights? Here we will talk about the skills inside! Weight, cast iron weight, weight manufacturer - how to properly handle the surface The application of sanding on the surface of cast iron weights is very common. The principle is to impact the accelerated abrasive particles against the surface of the cast iron to achieve rust removal, deburring, deoxidation or surface pretreatment, which can change the cast iron. The surface finish and stress state of the weight. Some parameters that affect the grinding technology need to be noted, such as abrasive type, abrasive particle size, spray distance, spray angle and speed. In addition to sanding, shot blasting is also a good choice. Jiujin weight - boutique build - your choice, our guarantee - welcome to shop to buy!

The grinding process can be divided into two types: air pressure spray gun and impeller shot blasting. The advantage of the grinding process is that it can remove the peaks, remove the burrs after die casting, stamping, flame cutting and forging, and the burr effect on thinner workpieces and pores. More preferably, it can remove the residual sand from the sand casting process, clean the rust stains of the cast iron or steel, clean the heat treatment, burn, hot forging, rolling and other thermal processes. In addition, in coating applications, it removes existing coatings or protective layers and provides a shiny surface on defects that cover the casting, such as cracks or cold lines.
In addition to the surface stress, it can provide a consistent roughening surface, oiling and spraying effect. In high-stress cast iron weights such as springs and connecting rods, it will be partially beaten and deformed and will be strengthened. . This strengthening effect requires the use of round abrasives such as stainless steel pellets for use in high energy shot blasting machines or special powerful sanders. To determine the surface strengthening effect of the machine, the test workpiece can be shot blasted or polished, and then the deformation amount is determined to meet the requirements.
