Machining Center

IS3 have a lot of experience in machining work, since it was in this sector which this activity started and it was through this that was developed its know-how, reflected, today, in the quality of parts and tools produced. Here, it's executed all kinds of jobs, as it has available a set of equipment that let to offer a service that meets the highest quality standards such as:

  • Mechanical and CNC Lathes
  • Threading Machines M64
  • Milling Machines CNC
  • Machining Centers CNC
  • Surface grinding machines CNC
  • Machining of forged, casted and machined and welded parts
  • Building of own tooling and jigs for the production of the parts
Additional equipments

In addition to the equipment mentioned above, it is worth highlighting the importance of some of others production support equipments, such as:    

  • Tube bending machines, up to diameter of 60 mm
  • Calandra, capacity curl of 8mm thickness per 3000 mm long
  • Automatic tape saws, until CNC 250 degrees and disc feeder, up to 60 x 100 mm
  • Automatic washing machines
  • Guillotines CNC, with 12 x 3000 mm cutting capacity
  • CNC hydraulic press brakes, force up to 150 tones. and 200 tons., length 3000 mm
Surface Treatment
IS3 offers its customers several different coating options, whether performed internally or subcontracted out to neighboring partners:
  • Powder or Epoxy Painting (800x1600x3000mm)
  • Liquid Painting
  • Cataphoresis
  • Hot dip Galvanizing
  • Zinc-coating
  • Geomet
  • Chroming
Line automatic painting
IS3 offers two lines of automatic electrostatic painting, with capacities of 350x1200mm and 800x1600x3000mm with degreasing tank, wash in running water, passivation and drying tunnel.

Galvanization
Most of the products manufactured by IS3 go through a hot galvanizing process, anticorrosion, which gives them longevity. This treatment is subcontracted and can be performed by immersion, for medium and large parts, or by centrifugation, for smaller ones.
Production and Control Jigs
The IS3 is an autonomous and independent company, thanks to its internal production of tools and gabarits for presses, machining centers, welding procedurews and also for production control.
Assembly, packaging and transport
On the semi-finished or finishes sets production, is very often required the assembly, packaging and trasnport of the parts in trucks or sea container. This company has the capacity and experience to incorporate electricalc components, wood, rubber, plastic, polyurethane and others in the final product. Because besides having good partners, in different areas, also has the facility to produce, internally, molds for the production of these components.
Technical support
Thanks to a team of experienced technicians, the company provides its customers a specialized and continued support in their projects. In addition, it participates in their development and improvement, in order to optimize production and reducing unnecessary costs in manufacture.

It is in this department that are thought and designed the gabarits and also the essential tools for the production and control of all parts.

The design software and programming mainly used are : Inventor CAD-CAM and Catia.
