The manhole cover mold is produced by an injection molding machine. The mold for this production process is safe because the manhole cover mold does not require the help of a large machine, only requires simple operation
每天的生产量达到数千个，所以只需要增加模具的购买数量，同时井盖模具相对环保。The daily production volume reaches thousands, so we only need to increase the purchase quantity of molds, and the manhole cover mold is relatively environmentally friendly.
现有的水泥形式只是在生产过程中改变的，整个生产过程是环保的。本实用具有重量轻、强度高、抗震、耐用防火、绿色生态环境保护等特点。
The existing form of cement is only changed during the production process, and the entire production process is environmentally friendly. This utility model has the characteristics of light weight, high strength, earthquake resistance, durability, fire prevention, and green ecological environment protection.
一般的图案是有许多小圆点，主要用于防滑，其厚度比普通水泥井盖薄。与其他水泥产品相比，井盖具有良好的抗震性和抗冲击性，从而提供了产品的韧性。
The general pattern has many small dots, mainly used for anti slip, and its thickness is thinner than that of ordinary cement manhole covers. Compared with other cement products, manhole covers have good seismic and impact resistance, thereby providing product toughness.
