The production of well cover is made by mold. Although it is a product we often see, how much do you know about its production process and material? If you want to use it better and give full play to the function of the manhole cover, you must first understand its manufacturing technology and material.

1、 Craft

The well cover mould is mainly used for the production of cement anti-theft well cover. The characteristic of the well cover mould is that the produced well cover size standard is suitable for use in residential areas, roads and other places. The steel mould for cement well cover is not limited by size and shape. It can produce various sizes of well cover, and can be weighted and customized. The general price of the plastic mould for well cover is about 160 yuan. The steel mould for cement well cover is not limited by size and shape Generally around 1200 yuan, various patterns and characters can be printed on the surface of the cement well cover, mainly to indicate the use of the manufacturer’s telephone, etc.

2、 Material

In the early stage, the prefabricated well cover mold was made of reinforced concrete, which was gradually replaced by cast iron and ductile iron due to its brittleness, aging and fracture. The mould of well cover has complex shape, high precision and long manufacturing cycle. The processing cost of the mould is far more than the material cost of the mould. The mould should also be made of high-performance materials.

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

2. Steel material: cold working die steel, hot working die steel, plastic die steel, high speed tool steel.

The quality of the finished product of the well cover mold affects the production quality of the well cover. A bad mold will make the production fail, reduce the use performance of the product, and can not guarantee the use safety. Therefore, we should pay attention to its rigor in the mold manufacturer.
