The production of well cover is made by mould. Although it is a product we often see, how much do you know about its production technology and material? In order to use it better, we must know the production technology and material of the well cover.

1、 Process

The well cover mould is mainly used for producing cement anti-theft well cover. The well cover mould is characterized by the production of the well cover size standard, which is suitable for use in the small area, road and other places. The steel mould of the cement well cover is not limited by the size and shape, and can produce various sizes of well cover, which can be reinforced and customized for various sizes. The general price of the plastic for the well cover mould is about 160 yuan. The steel mould for the cement well cover is about 160 yuan Generally, about 1200 yuan, various flower types and words can be printed on the surface of cement well cover, mainly for indicating the telephone use of the manufacturer.

2、 Material

The mould of prefabricated well cover was made of reinforced concrete in the early stage. Because of its brittleness, aging and fracture, it was gradually replaced by cast iron and nodular iron. The mould of well cover is complex in shape, high in precision, long in manufacturing cycle, and the processing cost of the mould is far more than the cost of the mold. This mold should also be made of high-performance materials.

1. Plastic materials: Engineering polypropylene, GPS, ABS, PC, PP, PMMA, AAS.

2. Steel materials: cold working die steel, hot working die steel, plastic mold steel, high-speed tool steel.

The production of the well cover mould affects the production quality of the well cover. The bad mold will make the production fail, reduce the performance of the product and ensure the safety of use. Therefore, we should pay attention to its rigor in the mould manufacturer.
