Mold Production Video

Use the correct heat treatment to produce excellent manhole cover molds. The mold temperature rises from time to time. During the production process. When the mold temperature is overheated, it is easy to produce mucous membranes and cause the moving parts to fail.
It is necessary to pay attention to the setting of a temperature control system to maintain the working temperature of the mold within the effective range, reduce the occurrence of grinding stress, and have a great effect on the maintenance of the life of the mold.

Manhole cover moulds are in the same field of competition with international competitors. my country's manhole cover mold industry gives full play to its own advantages and strives to occupy a place in the international market. Our country's low labor cost and raw material prices, which make our country the focus of attention in the current international environment where cost saving is urgently needed.

The types of manhole cover molds are: cement round manhole cover mold, county municipal manhole cover mold, inspection manhole cover mold, cement water manhole cover mold

The manufacturing precision, strength, working life, and manufacturing of molded manhole cover molds should be carefully understood. The heat treatment of the manhole cover is an important process to ensure its performance.

If the heat treatment of the manhole cover mold is improper, it will cause the mold to crack and fail prematurely, especially if only the adjustment is used without quenching, coding cracks will occur several times during the production. This is the thermal stress during the cooling process and the structure during phase change. As a result of stress superposition, quenching stress is the main cause of deformation and cracking. It should be tempered to eliminate it. The mold must be preheated to a certain temperature before production, so as not to cause a large temperature difference between the inner and outer layers of the mold and cause cracks on the surface of the mold. .
