1. High quality materials purchased with strictly quality check.
2. Each product checked strictly before packing.
3. We are professional manufacturer for over 25 years.
4. Trial order or mixed orders are accepted.
5. OEM orders are welcome.
6. Prompt delivery.
7) Any type of casters and wheels can be customized.
We adopted advanced technology, equipment and high-quality materials to ensure the flexibility, convenience and durability of our products. In different circumstances, our products have wear, collision, chemical corrosion, low/high temperature resistance, trackless, floor protection and low noise features.
1. Reduce (stretch, twist) the finished product of the caster bottom plate five times to the aspect ratio under the limit load in the work (length or short or the limit twist view angle in the work), and accurately measure the aspect ratio of the fourth and fifth times (Or length, viewing angle) its value does not change, it feels that there is no deformation.
2. The load and standard tolerances, surface appearance and shape tolerances of the finished products of industrial casters should be tested after the deformation, but the load and standard tolerances should also be qualified before the deformation.
3. Fatigue test, tensile test and simulation experiment of the bottom plate of industrial casters: testing by testing instruments.
4. The surface quality of the bottom plate of industrial casters can be inspected by estimation or 5 times high magnification magnifying glass.
In short, it is probably clear which aspects of general caster inspection mainly detect, but the above is the specific inspection process and method, and the caster inspection process is different for different caster manufacturers.
