The pillow inside the formwork is compacted with watering with watering with water, after which the reinforcement of the matrices, the heating system and, if necessary, pushes are laid in the formwork. With electric heating, the top of the electric wires and exfoliators should lie in the plane of the working surface of the matrix.
Matrices can also be made of concrete of the brand “200”. After cooling concrete on the flat parts of the matrix, a working surface is arranged from the finishing solution of the composition 1: 2 or 1: 3 on the cement of the “400” brand and river sand. The layer of the solution is smoothed with wooden racks and iron and iron until the crust of cement stone is formed 3-4 mm thick. The working layer of the matrix can be made from a mosaic solution with subsequent grinding.
Using the template, the depression in the matrix for the ribs of the part is profiled with the same solution and their surface is finished in the same way.
Reinforced concrete matrices can be used as mobile forms when organizing production in a flowing-agent technological scheme. In this case, they are made in the form of a light thin-walled structure consisting of a steel frame-frame and reinforced concrete filling. If you need to transport goods, you should contact reliable professionals. You can find out the cost of transport services in Tver from an experimental company online.
Matrices can also be made from thin cast -iron inventory prefabricated sections connected by bolts.
The cast -iron matrix consists of standard elements made by the factory way. The release of a wide range of plates can be organized using only four types of modulated standard sections. For the production of plates of each type, only two or three types of sections mounted in the required quantity and a certain sequence are used, respectively, the design of the manufactured parts.
