Precision casting is an advanced near-net-shape forming process. It is a casting method that uses a fusible primary mold and core to shape the casting. Investment casting can produce precise and complex castings of various alloys. The castings are close to the final shape and size of the parts, and can be used directly without processing or after little processing. It is suitable for the production of small and medium precision and complex castings and various production batches.

Because there are many uncertain factors in the operation of explosion-proof electrical equipment, such as: overload, overvoltage, frequent operation, short circuit, and lack of equality, the control equipment will be severely tested. If the explosion-proof electrical equipment has low on-off capability, it is sealed. The inside of the explosion-proof electrical enclosure works easily and is damaged and an accident occurs.
Many product manufacturers have neglected this problem, and the quality requirements of the selected components are not high, resulting in accidents caused by burning components. Therefore, in selecting such components, in addition to the above-mentioned derating problem, there should be a relatively accurate understanding of the load state and capability of the motor, but this problem will not cause problems if it is given sufficient attention.
