Third-party water jet cutting, press brake bending and steel shearing services in Castellana Grotte

Production of press-bent parts with semi-automatic lathes

There third-party steel processing represents an operational solution for companies, designers, and manufacturing facilities requiring precision-machined metal components without managing all production phases in-house. Officina Meccanica Leone Mastromarino processes various metallic and technical materials using dedicated machinery, offering support in the creation of components for a variety of industrial and technical applications.

The processes are carried out through controlled processes and specific equipment that allow us to work on materials such as steel, stainless steel, aluminum, copper and composite materials, maintaining the structural integrity of the components and meeting the required design specifications. Activities include operations such as water cutting, press bending, shearing, calendering and turning, allowing for the production of machined parts with a high level of dimensional precision.

The organization of the production department allows for the management of both custom-designed production and the processing of components already designed by the customer, with the possibility of producing single pieces or production series. The approach adopted in third-party steel processing aims to ensure operational continuity and compatibility with the needs of production chains that require metal components machined according to specific technical criteria.

Numerically controlled water jet cutting machines

Processing operations are carried out using CNC machines and dedicated mechanical equipment, designed to work on various materials and thicknesses. This approach allows us to achieve results consistent with the required technical specifications, maintaining precision in processing and quality in cutting edges.

One of the most used processes is the high pressure water cutting, a technology that uses a mixture of water and abrasive to perform machining on metallic and non-metallic materials without generating thermal alterations. The work surface of 2000 x 4000 mm allows you to work on large sheets with high accuracy.

Through this technology it is possible to work on different materials and thicknesses, including:


  • maximum steel thickness 80 mm;
  • stainless steel maximum thickness 80 mm;
  • maximum copper thickness 80 mm;
  • aluminium maximum thickness 80 mm;
  • polycarbonate maximum thickness 120 mm;
  • marble of various compositions, maximum thickness 100 mm;
  • maximum glass thickness 80 mm;
  • maximum wood thickness 120 mm;
  • porcelain stoneware maximum thickness 100 mm;
  • various plastic materials maximum thickness 120 mm;
  • various building materials maximum thickness 100 mm.

Shears with 4000 mm cutting blade

Within the activities of steel processing industrial shears are also used with 4000 mm cutting blade, suitable for processing sheet metal and metal panels with linear precision. Processing can be performed on:


  • maximum steel thickness 8 mm;
  • stainless steel maximum thickness 6 mm;
  • maximum copper thickness 8 mm;
  • aluminium maximum thickness 8 mm;
  • polycarbonate maximum thickness 5 mm.

  • The use of dedicated machines allows for the production of cut components ready for subsequent mechanical processing or assembly.

Press brakes

There sheet metal bending It is performed using press brakes equipped with bending knives with a maximum length of 4000 mm. This process allows for the production of press-bent parts used in the production of metal structures, technical components, and light carpentry elements. The materials processed include steel, stainless steel, copper, aluminum, and polycarbonate with thicknesses up to 5 mm.

Calendering machines

For the creation of curved or cylindrical elements the calendering, performed using machine tools composed of rotating steel or cast iron cylinders. The material is passed between rollers to obtain controlled and uniform bends. The available equipment allows for the processing of sheet metal with a maximum size of 2000 mm and the rolling of tubes with diameters ranging from 0" to 2".

Semi-automatic lathes

A further area of the third-party steel processing concerns the production of mechanical parts through semi-automatic lathes, used to obtain components with controlled dimensions and precision machining on metal surfaces. This type of processing allows for the creation of elements such as bushings, pins, supports, or technical components used in various industrial contexts.
