Within this category, the so-called PPVC (pre-finished prefabricated volumetric construction) is gaining popularity as it allows “to do more in the factory and less on the job.”
The client, Integrated Precast Solutions (IPS), a subsidiary of well-known contractor Teambuild, is among the leading and most advanced players in PPVC construction around the world. IPS has extensive experience in multi-story residential construction projects in both the public and private sectors and has won numerous awards from the Building and Construction Authority of Singapore.
More than 45 types of 3D modules for PPVC have been required for this specific building project. In addition, Moldtech made a first subdivision into different groups, depending on the similarity of sizes and shapes. In this way, the entire project could be executed using only 5 different types of molds, since each type had the flexibility to manufacture 9 different elements by changing pieces of the outer side wall and other elements with special accessories fixed with bolts, magnetic formwork and drawers. Also, some of the molds were designed with a modular longitudinal adjustment, to adapt to different types of modules, and with double cores that allowed to manufacture two rooms in one piece.
The sizes of the manufactured item reach 10 meters in length and 3.5 meters in width, and each unit can weigh almost 37 tons.
Together with the hydraulic retraction system, which makes it possible to demold the unit in a matter of minutes, and the heating system, which reduces curing times, the molds allow up to 2 PPVC modules to be manufactured in 24 hours.
Designed to be flexible, not only for a single project, but for future projects, since it is possible to adjust them for other sizes, being reusable up to 60%.
Moldtech can provide a set of technological solutions for modular construction, from PPVC molds and flexible molds for 3D Prefabricated Bath Units (PBU), to 180º tilting tables and automated finishing lines for PPVC and PBU elements.
