Three Main Improvements in The Manufacturing Of Casters

In history, the manufacturing of industrial casters has combined forging, casting, stamping, and welding processes. The key components in the manufacturing process have not changed, and some have undergone changes in modern manufacturing technology. The key components of forged and cast industrial casters and wheels have not changed significantly in the past 50 years. Many manufactured products remain completely unchanged in terms of size and shape during these processes. The significant change in the manufacturing of industrial casters is the manufacturing of the continuous casting machine drilling platform, which is the main body of the continuous casting machine. In the past, standard components for stamping parts used in drilling rig manufacturing, forgings for rotating parts, or mutual welding. In production, accessories designed using iron engineering to modify them, such as brakes or toe guards, are then welded as standard components.

The manufacturing of casters has reached a new level, which has completely changed the motivation for casters manufacturing. The following three aspects are areas that need improvement in production:

1) Increase strength

2) Improving quality

3) The final product that reduces production time.

These improvements all come from laser cutting and forming drills that remove about 40% of the welding, greatly changing the design/construction process. Let's briefly discuss these three key improvements.

1. Increase strength - in the production of heavy-duty castor legs connected to the platform is manufactured on a single flat blank. Blank "development" to accommodate materials that will be consumed, with legs formed on top. The formation process is achieved by using a bending machine to move the leg material of the platform in a 90 degree direction. In a traditional way, the legs of the 'fixing/welding process' will be welded to the platform. During the forming process, when completed, the error rate is 25%, which is higher than that of the welding product, and cannot fail unless there is a total major failure part. The laser cutting/forming process completely removes potential failure areas from the finished product.

2. Improved quality - When all components are used during the stamping process, initially a clean material fails (about half the thickness of the material), the remaining part of the material will "escape", leaving an edge with a variation within the range of 0.03 inches. When a part is laser cut, the edge quality and hole (for axle distribution) can be maintained at 0.002 inches. The most significant impact of this precision is on the fact that, instead of grinding the hole to the final size, the hole is cut off as the initial ideal candidate, significantly improving the quality of the final product.

3. Shortening the production cycle, if a part of laser cutting/processing is properly designed, it is the result of cutting off the formation process close to the finished product. The reason for this is that essentially all components of the drilling rig are integrated into the original laser blank, thus avoiding little or no additional welding. Avoiding secondary processing will accelerate the manufacturing process of the product while controlling additional costs.
