Features of our precast concrete moulds
de hormigón/concreto

In Grupex, we manufacture custom moulds for block machines for the production of concrete precast products, including moulds for concrete blocks, paving stones, slabs, kerbstones, hollow blocks and special pieces, all with a focus on durability and exceptional performance in every production cycle.

  • High precision: Fully customised moulds, designed to manufacture the products you need, with the dimensions you require, and deliver consistent, high-quality results in every cycle.
  • Long service life: The moulds are designed and manufactured using high-strength materials and advanced technology, designed to withstand the most demanding working conditions.
  • For all teams: We manufacture custom moulds for all equipment on the market.
  • Modular design: possibility of manufacturing moulds with modular technology, so that only those parts that suffer wear and tear need to be replaced, thus achieving a longer service life.

High-quality materials and advanced manufacturing processes

We use high-strength steel and state-of-the-art components to manufacture concrete blocks and other products, ensuring superior quality and exceptional durability. Our advanced manufacturing processes include thermal cutting, welding, carburising and heat treatment to ensure maximum performance and total precision in every component.

Thanks to our constant innovation and the new design of removable cores in our block moulds, we have optimised service life and reduced unscheduled downtime, contributing to a greater return on investment for your business.

Mould components

Mould box

Manufactured from special wear-resistant steel, Hardox, with heat treatment for surface hardening and the placement of spacers along the entire height of manufacture. Manufacturing includes thermal cutting, welding and high-precision grinding processes, ensuring the uniformity and quality of each piece. This technique ensures high wear resistance, with a hardness of up to 60+ HRC at a depth of 1.5 mm.

  • High durability: superior hardness to withstand demanding working conditions.
  • Accuracy: cutting and specialised treatment to ensure a long service life in each production cycle of concrete blocks and other prefabricated products.

Counter mould

Made from special tempered, milled and polished steels, with automatic precision machining. The surfaces are hardened by heat treatment and coated with carburising for superior abrasion resistance, achieving a hardness of 60/62 HRC at a depth of 0.5/0.8 mm. Precision adjustment is carried out using specialised machinery, ensuring the exact fit of each component.

  • High precision: manufacture of the mould using precision machinery.
  • Better performance: ensures the consistency and uniformity of parts throughout their service life.
Advanced mould technology

At Grupex, we apply advanced technology in the manufacture of moulds for making concrete blocks, ensuring precision, efficiency and durability in every piece. We use automated design and machining systems that enable consistent production and high-quality results. Thanks to the use of heat treatments, laser cutting processes and CNC machining, our moulds offer superior performance and extended service life, even in intensive production environments.
