welding machining industry
Materials
We design, manufacture and test vessels and equipment in stainless steel, nickel alloys, duplex e superduplex. The vast product range (heat exchangers, reactors, etc.) allow us to satisfy many requirements of the chemical industry.
Experience
Specialized in the chemical industry, W.M.I. knows the needs linked to this sector thanks to the entrepreneurial and manufacturing knowledge. A know-how that makes the difference.
Quality
The work method allows to analyze the production processes, step by step in order to guarantee the quality of the final product. From the beginning the product is tested virtually with a design and calculation software.
The Design Phase
The technical office can determine the mechanical resistance, the durability and the natural frequencies of the final product. It can also test the load instabilities, make pressure vessel analysis and of complex loads with the Simulation software implemented with the 3D CAD and a dedicated calculation program, which follows the ASME VIII div. 1 code.
Mechanical calculations are performed using the finite element method (FEM) and its dedicated calculation software, which allow to analyze the feasibility right at the beginning of the process.
The construction drawings are realized through 3D modeling and 2D drawings to have a tangible idea of the project, guaranteeing a safe and good final result.
The Production Processes
From the formal project to the final testing many production steps follow one another to realize the end product.
The 2D and 3D fiber laser enables to cut, drill and chamfer any kind of object.
The forming is carried out by bending and calendering (even square sections). The weldings are performed manually and with the welding robot which has been equipped with the © EWM AG Force TIG welding head.
The turning, milling and boring is mainly performed within the company.
