Concrete Extrusion Machine

Product Description

Concrete Extrusion Machine

A concrete extrusion machine is a specialized piece of equipment used in construction and civil engineering projects to create various concrete structures with specific shapes and dimensions. The process involves pushing or extruding a semi-fluid or viscous concrete mixture through a specially designed mold or die to form the desired shape. This method allows for the creation of structures that are more intricate and precise compared to traditional casting methods.

The working principle of a cconcrete extrusion machine involves the following steps:

Concrete mixing: The machine is equipped with a concrete mixing system that combines cement, aggregates, water, and any necessary additives or admixtures. The ingredients are mixed thoroughly to achieve a homogeneous concrete mixture.

Formwork preparation: The machine has a formwork system that consists of a set of molds or templates. These molds are designed to shape the concrete into the desired dimensions and surface textures of the wall panels. The formwork is prepared by applying release agents or other treatments to facilitate easy removal of the panels later.

Extrusion process: The concrete mixture is fed into a hopper or a conveyor system that transfers it to an extrusion chamber or a specially designed die. The extrusion chamber applies pressure to the concrete, forcing it through the die. As the concrete passes through the die, it takes on the shape and dimensions of the wall panel, with the desired surface patterns or textures imprinted onto it.

Reinforcement and embedding: Depending on the design requirements, the machine may incorporate reinforcement elements such as steel bars or mesh into the extruded concrete. These reinforcements enhance the strength and structural integrity of the wall panels. Other embedded elements like electrical conduits or insulation materials may also be included during the extrusion process.

Curing and finishing: Once the wall panels are extruded, they need to be cured to achieve the desired strength. Curing methods can include steam curing, thermal blankets, or other techniques. After curing, the panels may undergo finishing processes such as surface treatments, polishing, or the application of protective coatings to enhance their appearance and durability.

Panel cutting and handling: Once the panels have achieved the required strength, they are cut to the desired lengths using cutting mechanisms integrated into the machine. The cut panels are then removed from the formwork and prepared for transportation and installation at the construction site.

Advantage:

Brick walls is time consuming to erect and costly to keep maintaining. Our Pre-stressed Precast concrete Hollow core Boundary wall or Compound walls overcome these handicaps of traditional brick walls.

Extrusion of Boundary wall slab / panel is 5 times Faster, Easier & Most Economical solution for production compared to the conventional Technique of individual panel cast-in-site.

Extrusion speed of the machine for the Light-duty Boundary wall slab is between 1.8 to 2 meters per Minute with a limited labour force. (i.e. it extrudes in one minute one panel of 7 feet).

Being Hollow it’s self-weight is reduce, saves on concrete weight & thus save money with same load bearing capacity as compared with cast-in-situ.

Our Precast Concrete Boundary walls are made/ erected with the help of Supporting ‘H’ column / posts erected directly into the ground which have grooves to accommodate Boundary wall slabs / panels.

This can be also installed vertically without post as a boundary wall or cold storage rooms or industrial sheds, Pre-fabricated mezzanine floors etc.

Production process

Producing Site of concrete extrusion machine:

1. Prestressed concrete fence wall&post producing bed prepare and tensioning.

1.1 Cleaning the producing bed: Clean the concrete residue on the producing bed with special tools and make the platform surface clean, smooth.

1.2 Painting parting agent: The adopted parting agent must be up to the required standard without harmful
chemical substance.

1.3 Distribute the steel wire.Steel wire of low relaxationand stress relieving is adopted .

2. Precast concrete fence wall&post materialcompositions and quality standard

1.1 Cement: 32.5R or 42.5R Portland cement and ordinary Portland cement

1.2 Sand: Medium sand

1.3 Stone: Rubble and broken pebble are optional

1.4 Water: Drinking water without harmful substance

1.5 Dry concrete is used for precast concrete fence wall&post with a strength grade of C30 or C40.

3. Prestress concrete fence wall&post technological flow

Cleaning the producing bed→ painting parting agent→ distribute steel wire and fix→tensioning the steel wire→ mix and transportation of concrete → slab molding →make testing block→ covering and curing →testing block intensity →relief the steel wire→ cutting slab→ storage

We can design and manufacture all kinds of concrete forming equipment according to customer's demands. Meanwhile we also can provide our customers a complete set of technology and solution for all producing flow.
