Precast concrete components are made using steel molds due to several repetitions, generally above 500. Usually, precast components are cast on steel molds. The mould designer uses steel plates ranging from 4 to mm, C-channels ranging from 50 to 200 mm, Angles ranging from 50 to 150 mm and flat bar thickness from 100 mm to 30 mm. Usually, the supporting steels such as angles/ channels/ flats used depend upon the plate thickness chosen based on the span of the mould designed. Hydraulic jacks for prestressing or tilting the table mould used range from 2 tons to 50 tons capacity. Let’s see the different types of Precast Concrete Mold we can do today.
1.Wall mold
Wall molds are used commonly for making slabs and wall panels as the cost of these molds were much lesser comparatively. A common bed shall be prepared and the side form shall be custom made as per requirement. Here the wall panels are cast flat on the bed. It is then handled and transported in the horizontal position of the site. During the erection of the wall panel it is tilted using the cranes and put in position.
2.Staircase Molds
Staircase molds are fabricated in an upside position. The landing slab shall be integrated with the flight of the stair or as a separate slab. These staircase elements produced are tilted after producing or at the site prior to installation time. It is recommended to use standard tread and riser dimensions. As and when these dimensions change another mould has to be fabricated to produce the same.
3.Compression Mold
4.Customized molds
Once can produce any kind of mould depending upon the requirement of the concrete products by the clients. Some of these molds are- culvert mould, storm water drain mould, lintel beam with sunshades, tunnel molds etc.
