Mesh welding machine for precast slabs, double and solid walls

The mesh welding machine developed by mbk Maschinenbau GmbH is a cutting-edge solution for producing precast slabs with in-situ topping, double and solid walls. This machine incorporates technical innovations such as a mesh conveyor system that allows for different depositing positions and stack formation according to the pallet layout. It offers flexibility in providing meshes based on customer requirements and ensures just-in-time placement on the pallet.

mbk, headquartered in Kisslegg, Germany, specializes in efficient and reliable solutions for the construction, concrete, and precast industry. Their highly skilled team integrates customer needs and requirements into modern production environments, responding to market changes with innovative approaches and designs.

Efficient and intelligent reinforcement production is crucial for highly automated precast production of walls, double walls, and precast slabs with in-situ topping. The meshes produced by mbk find applications in building construction, residential and industrial construction, particularly in precast concrete elements with recesses for window and door openings, walls, and ceiling recesses.

The flexible mesh welding machine, MSM-M, directly welds reinforcing steel meshes according to individual CAD drawing specifications. It can produce mesh widths ranging from

500 mm to a maximum of 3,500 mm and mesh lengths ranging from 1,000 mm to 8,000 mm. Smaller and larger sizes are also available.

For automatic loading of longitudinal and transverse wires, mbk utilizes the DRA-M multiple rotor straightening and cutting machine. It handles standard wire diameters from 6 mm to 16 mm, adjustable up to 5 mm to 20 mm. The longitudinal reinforcement is transferred automatically from the DRA-M to the welding unit of the mesh welding machine, while the transverse reinforcement lengths are assembled by the DRA-M and transferred as required.

Once the mesh is completed, it is automatically labeled with text and/or barcode, and a mesh conveyor system enables further processing through a fully automated traverse. The mesh is transported for further processing to the bending beam for Z-bending or directly to the stacking position. In the subsequent circulation plant, the mesh is deposited and stacked according to the master computer specifications.

The MSM-M mesh welding machine from mbk ensures everyday suitability, cost-effectiveness, and low maintenance requirements. It can be tailored to meet specific production requirements, offering different performance levels and automation accessories. The plant layout is flexible and adaptable to local conditions. Special and standard meshes can be produced for series and end stirrup production.

To produce precast slabs, the machine is equipped with a mesh bending station for frontal Z-bending of the bar overhangs. The automated traverse allows the produced slabs to be deposited on an additional stacking pallet for external use in structural precast elements and construction site additions.

mbk’s strength lies in developing and implementing individual, modern, and future-oriented solutions based on customer needs. They also prioritize professional spare parts and maintenance services. These qualities have earned mbk Maschinenbau GmbH a strong reputation worldwide, as they value customer relationships and their impact on market shares.
