The principle of formation of concrete concrete mold


The raw material of the concrete preform mold mold is generally plastic injection molding and sheet metal steel mold molding. The concrete preform plastic mold is made of polypropylene plastic granules and injected into the pre-prepared concrete preform cavity through high temperature treatment of the injection molding machine. After the cooling process, the concrete precast mold is formed; the steel mold of the concrete prefabricated part is made by 3-8 mm iron plate after crimping, cutting, styling, reinforcement, welding, assembling, grinding and other procedures.


Precast concrete mould

Concrete precast mold is a kind of cement product of cement product mold, commonly known as concrete precast mold, concrete precast mold or concrete precast mold, and 133/154/38000 is a concrete precast mold mold that specializes in producing precast concrete parts. The following are all used in high-speed roadsides, high railways, roadsides, highways, roads, rivers, reservoirs, embankments, embankments, and mountains. According to these characteristics, concrete precast molds are also known as: high-speed concrete prefabrication. Mold, high-speed concrete precast mold, road concrete precast mold, road concrete precast mold, river concrete precast mold, reservoir concrete precast mold, riverbank concrete precast mold, dam concrete precast mold, mountain concrete precast Local cultural differences such as molds may result in other titles such as concrete precast model or concrete precast molds, etc. but are collectively referred to as concrete precast molds according to the industry.

The material of the concrete preform mold mold is generally plastic injection molding and sheet metal steel mold molding. The concrete preform plastic mold is made of polypropylene plastic granules and injected into the pre-prepared concrete preform mold cavity through injection molding machine high temperature processing. After the cooling process, the concrete precast molds are formed; the steel molds for the concrete prefabricated parts are made of 3-8 mm iron plates after crimping, cutting, styling, reinforcement, welding, assembly, and grinding.

The principle of the production of concrete preforms

Prepare a concrete precast mold, a vibrating platform, and a proper amount of mixed concrete.

The mixed concrete is poured into the concrete preform mold, vibrated on the vibration platform for about 30 seconds, and placed under a cool and dark warehouse.

Place it for a certain period of time about 24 hours or so in winter for 2-3 days.

4. After the concrete is solidified and molded, demoulding or demoulding is performed.

Concrete preform mold classification

The concrete preform molds can be divided into concrete preforms plastic molds, concrete preforms plastic molds, concrete preforms plastic molds, concrete preforms plastic mold boxes, concrete prefabricated steel molds, concrete precast steel models, concrete precast steel molds, The prefabricated steel mold box is called.

Concrete preform mold material characteristics

Polypropylene (PP) is generally used as a plastic mold for concrete preforms. The material has good forgeability, machinability, hardenability, and grindability.

The steel mold of concrete prefabricated parts is generally made of silicon steel as raw material, and its material has good plasticity, hardness, processing type, super toughness and so on.
