Sansiri invests in sophisticated battery mould technology by Tecnocom

Sansiri Public Co. Ltd, based in Bangkok, Thailand, has more than three decades of experience in the field of construction projects and real estate development and has successfully delivered hundreds of projects all over Thailand. It has gained a reputation as one of the leading real estate developers in Thailand for quality housing, offering single houses, attached houses and high-rise buildings.


To construct and deliver high-end quality housing projects with a focus on meeting time schedules and minimum usage of resources, Sansiri is using state of the art precast concrete technology in their precast concrete factory in Lam Lukka. Having invested in the new battery mould technology, Sansiri is increasing the efficiency and productivity of the factory and also widening the range of products and design flexibility. The battery moulds were designed, manufactured and commissioned by Tecnocom, one of the seven companies of PROGRESS GROUP, a leading global supplier of precast technology.

Phusak Yuthayanont, Deputy Vice President of Engineering & Logistics Precast Concrete Factory, is very satisfied with the new battery mould production

Sansiri invested in two individually designed battery moulds from Tecnocom, each of which is equipped with 20 pockets (10+10), one with dimensions of 6.00m x 2.85m for the production of partition walls, and the second of 4,00m x 1,50m for the production of fencing elements. Due to the flexibility of the basic shuttering system, Sansiri is able to manufacture precast concrete elements in various sizes, thicknesses and patterns.

The battery moulds from Tecnocom ensure the highest productivity and quality by using special high frequency vibrators installed at every pocket for constant concrete compaction. This compacting technology allows for the production of precast concrete elements with very smooth surfaces and the highest degree of surface flatness.

The Tecnocom battery mould production is supported by a BlueMesh M-System mesh welding machine from progress Maschinen & Automation AG, also a company of the PROGRESS GROUP, which is producing tailormade wire mesh for each and every precast element produced in the battery moulds, as well as the company’s carrousel plant, provided by EBAWE Anlagentechnik GmbH, another PROGRESS GROUP company. The welding machine is designed as a flexible production unit for tailormade reinforcement mesh directly from coil. The combination of these machines and equipment has led to major savings in manpower requirements and raw material wastage.

In order to further enhance its high-quality production standards, Sansiri has invested additionally in a customized magnetic formwork system developed by Tecnocom especially for the Sansiri battery moulds. This customized magnetic system allows Sansiri to perform shuttering and formwork activities with the highest accuracy in a minimized time frame.


Daily, a fleet of trucks leave from Lam Lukka factory to deliver a significant number of precast concrete elements to various project sites in the greater area of Bangkok. The outcome of the daily battery mould production is currently used for partition walls in different dedicated condominium projects, and the fencing elements can also be seen in all Sansiri projects.

This success story is based on a very professional and trustful partnership between Sansiri and PROGRESS GROUP. Tecnocom provided all services for a smooth and professional implementation of the battery moulds, starting with expert advice during the design and decision taking phase, followed by very transparent manufacturing, delivery and installation activities, and finally sending a team of three battery mould experts to the Sansiri factory for the job training.
