Prefabricated part mould is a cement product mould of Baoding Jianfeng mould, commonly known as prefabricated part mould, prefabricated part mould or concrete prefabricated part mould. It is specialized in the production of prefabricated part mould and mould. It is usually used in high-speed roadside, high-speed railway side, road roadside, highway roadside and some river, reservoir, dam, embankment, mountain and other places. According to these characteristics, prefabricated die is also called: High-speed prefabricated mold, high-speed railway prefabricated mold, road prefabricated mold, highway prefabricated mold, river prefabricated mold, reservoir prefabricated mold, embankment prefabricated mold, embankment prefabricated mold, mountain prefabricated mold and other local cultural differences may cause some other names such as prefabricated model or prefabricated mold, but they are collectively called prefabricated mold according to the industry .
The raw materials of prefabricated mold are generally plastic injection molding and sheet metal steel mold molding. The prefabricated plastic mold is made of polypropylene plastic granule, which is injected into the prefabricated mold cavity by injection molding machine at high temperature, and then the prefabricated mold is formed after cooling treatment. The prefabricated steel mold is made of 3-8 mm iron plate through many procedures, such as crimping, cutting, modeling, strengthening, welding, assembling and polishing.
Principle of prefab generation
1. Prepare one mold for prefabricated parts, one vibration platform, and appropriate amount of mixed concrete.
2. Pour the mixed concrete into the prefabricated mold, vibrate through the vibration platform for about 30 seconds, and place it in a cool warehouse away from light.
3. Place for a certain period of time about 24 hours in winter, it is generally placed for 2-3 days.
4. After the concrete solidifies and forms, the mold is dismantled or demoulded.
