A magnetic field forming mold for manufacturing a permanent magnet element is usually made of a high-strength austenitic non-magnetic steel to form a negative mold. An inclination of 1:200 to 250 is required around the inner wall of the cavity. Since the cavity has a deformed shape, it is difficult to use mechanical processing, and when it is manually processed, not only the production efficiency is low, but also it is difficult to achieve uniform inclination. To this end, we used a simple device as shown in the figure to carry out chemical corrosion and achieved
Cold Room High Speed Rolling Doors
Cold room High Speed Doors are specially designed for cold rooms, refrigeration warehouse, and cooler rooms. Its door curtain is made into double skin structure filled with thermal insulation wool. With both fast running speed and thermal insulated curtain, such cold room rapid doors can help reduce heat loss and keep low temperature inside cold rooms. This will obviously reduce eletricity energy cost for busy traffic areas.
