This section describes our key equipment & moulds for the production of precast concrete elements used in residential buildings.
Precast installation for residential projects
Residential construction projects with precast elements
Moldtech tilting tables are designed to produce prefabricated concrete panels in various thicknesses for residential, commercial and industrial buildings. Its tilting mechanism allows removing easier the panels in vertical with less time for concrete hardening.
This tilting mechanism consists of a set of telescopic hydraulic cylinders and its number and strength is in accordance to the size and load capacity of the table. The cylinders are activated by a hydraulic unit with electrical control panel which can either command one or more tables, depending on the project.
Tilting tables can incorporate one or more sides depending on the kind of panels to be casted.
The sides of the tilting tables may be may be fixed, collapsible or adjustable in height. In addition, the movement of the collapsible and the adjustable sides can be performed mechanically or hydraulically.
Panels for industrial buildings tend to be casted with a standard size and, therefore, a table with a fixed and a collapsible side is usually used, whereas panels for residential project may vary greatly in size and shape and therefore require a more flexible solution.
The sides incorporated to the tilting tables are usually complemented by flexible shuttering systems using magnets. These shuttering systems are also used to form the panels’ window and door openings. Moldtech offers a variety of choice in shuttering systems looking for the best solution for each project.
Tilting tables can incorporate a vibration system consisting of a series of vibrators that can be electric or pneumatic.
Other option to increase the production of the tilting tables is the finned pipe system with isolation canvas for heating. This system leads hot water or steam to accelerate the concrete hardening.
In order to guarantee a smooth and shiny finish of the panel surface, Moldtech can give the casting surface of the tilting table an optimum polish creating a “mirrow like” effect.
Fixed tables specially designed and built to produce concrete floor slabs and pre-slabs. The reinforced pre-slabs with short span are usually used like lost formwork between bridge girders, for the construction of viaducts. The use of pre-stressed pre-slab with medium span are more common in residential or industrial buildings, in combination with lightweight and isolation elements.
Fixed tables can also feature vibration system and heating system for a better concrete finishing and an accelerated concrete hardening.
MOLDTECH manufactures and supplies fixed tables with or without pre-stressing capacity to allow the precasters to deal with all type of projects based in pre-slabs. The fixed tables are normally equipped with a fixed side and a collapsible. These tables can be manufactured in accordance to the maximum width required by the client and the casting dimensions can be adjusted by using different shuttering options.
This mould is used for the production of sandwich-type reinforced walls with 2 concrete layers and for instance a layer of insulation material in between. Its design allows the production of panels of different thicknesses. It is widely used in basements and underground parkings. Using panel formwork it is possible to insert window and door openings.
This mould is a hybrid between a tilting table and a battery mould. There are 2 surfaces: one horizontal and one vertical. On the horizontal surface one could cast panels with for instance a first layer of bricks, natural stone, marble etc. and a second layer of reinforced concrete and insulation material. After casting the horizontal surface, this is tilted forming one piece with the vertical part as if it were a battery mould. The vertical part, in which previously has been placed its own reinforcement, electric circuit cables and boxes etc.. is then casted obtaining a smooth finish of the other panel surface.
This mould is specially used for making panels which on both sides need a smooth finish. The size and amount of panels can be adjusted to the requirements of the client, the vibration system can be either electric or by air vibration. A battery mould provides a high production capacity using a minimum of space.
Mould for staircase is a double or single mould that allows manufacturing staircase stretches. The characteristics of the mould (tread depth, riser height, number of stairs, landings, weight of staircase) are all in accordance to the precaster’s requirements. The opening/closing movements can be provided for mechanically handling with crane as well as for totally hydraulic activation operated from a hydraulic unit with electrical control panel. The fastening system in the upper part of the mould is based on easy-to-use Dywidag rods. The mould also can feature external vibration.

In this new era in which agility, and flexibility to provide solutions to market requirements are essential factors. Industrialisation becomes a key element, since it is one of the most attractive solutions for developers and also for final users. It is necessary to stop thinking in a traditional way and we need to apply the industrial approach.
Minimize the ecological footprint and improve the working environment.
MOLDTECH is not a general supplier for industrialized solutions, it is a specialized precast concrete equipment company. Therefore, Moldtech has an important knowledge of the features of the final product, as well as the particularities of the production process. The high level of specialisation and internationalisation of the company after a big amount of important projects worldwide, makes us aware of the latest trends in industrialized construction. We have solutions for every single scenario and we could look for the most suitable solution following client’s necessities/ requirements.
Adaptability and highest quality guarantees.
Mould for the manufacture of concrete elements with 3D system: casting the 4 walls and the floor in a single monolithic piece of great structural resistance. The moulds are fully hydraulic on the outside and they have an innovative retraction system of inner walls for perfect demoulding. 180º turning devices are supplied with the moulds to the correct turning operation of the elements. Therefore, this mould facilitates both assembly and final installation times.
Modular mould system for manufacturing drycast concrete pieces to build elevator shafts. The size and thickness of the frame can be adjusted by inserting or removing additional segments. This allows the mould to produce frames compatible with most elevator manufacturers. The use of drycast concrete enable quick demolding of the piece, which allows manufacturing a considerable number of pieces per day.
