We have a reusable, flexible, and fully inflatable mold that replaces heavy steel formwork—developed for industrial processes involving concrete or refractory materials.

Traditional molds are heavy, unsafe, and time-consuming

Many industries still use steel molds to pour concrete or refractory material. These are large, heavy, and require intensive assembly and hoisting work in confined spaces. This poses risks to safety, ergonomics, and production time.

The inflatable mold from Buitink Technology

Buitink Technology developed a lightweight alternative: a reusable inflatable mold made of technical textiles. The mold is easily positioned when empty, then pressurized with air to form the exact desired geometry. Smart compartmentalization and pressure control keep the mold stable during the pouring of concrete or refractory material.

Waarom kiezen voor een opblaasbare mal?

• Safety: no heavy lifting, no hands on the load
• Ergonomics: assembly without lifting or crawling
• Speed: can be installed and removed in minutes
• Reusability: durable materials (aramid-reinforced fabric)
• Precision: constant pressure guarantees accurate shapes
• Low maintenance: easy to clean, replaceable protective apron

Lightweight, yet resistant to tons of concrete

The mold consists of multiple air chambers made of heavy-duty coated technical fabric that is resistant to wear, pressure, and temperature. With air pressure of up to approximately 0.2 bar, the structure can support more than 6 tons of concrete. Pressure relief valves and vacuum connections ensure maximum safety.

Suitable for temperatures up to approximately 250–300 °C with refractory materials.

Industrial mold engineering

Where can an inflatable mold be used?

• Pouring refractory components into furnaces or mixers
• Temporary formwork for concrete repairs or maintenance in tanks/silos
• Complex concrete shapes or architectural elements
• Prototyping and R&D applications in laboratories
• Formwork for composites or casting resins
