Production

The organization of the production process in a prestressed prefabricated plant is a complex and very specific process, which must always be adjusted both to the requirements and to the availability of the main resources:

The most common is to work on request, since the wide range of products available, both in morphology and in length, greatly complicates the stock forecast, especially if the storage availability is limited.

By way of illustration, some basic examples of production can be shown:

4 heated casting beds with passages

4 casting beds of 140 m will be considered, with the passages between them. The passage arrangement between adjacent beds allows the machines working on said tracks to be crossed without limitations. This facilitates the organization of the work, being possible to make the tasks performed in each bed independent.

In addition, the existence of heating makes it possible to assume that all the molded beds will be able to be removed the next day, without limitations.

In addition, a working period of 10 h is assumed.

The following graph shows in a simplified way a possibility of productive organization:

It is observed that it is possible to achieve a production of between 3 and 4 beds daily, every other day, although this requires working with very narrow margins of maneuver in the face of possible unforeseen events.

8 casting beds without passages

If 8 casting beds without the passages are considered, the limitations between adjacent tracks must be taken into account when organizing production. However, with these resources it is easy to produce 4 beds a day, much more loosely than in the previous scenario.

Some aspects ignored in the previous examples:

It is assumed that sufficient human resources are available to perform the necessary tasks in parallel.
The heating may support removing a molded product on the same day of its molding, but this option has not been considered.
The times of some jobs, especially molding, may differ significantly depending on the type of process and the geometry to be formed.

The objective pursued at all times, and since its implementation, is to maximize productivity and economic performance, reducing to the maximum those incidents that may harm the results obtained.
