ABOUT SAIP PATENTED TECHNOLOGIES AND THEIR APPLICATIONS

24 април 2019

Inverigo (Co), Italy – Since the very beginning - more than 40 years ago - SAIP has always looked ahead trying to overcome limits of technologies in use and find out more effective solutions. That’s the everyday challenge and passion of our R&D team which is fully dedicated to the research and development of new solutions and to the improving of the existing technologies.

Hereinafter, they’ll introduce you a few of our most popular technologies which have been recently patented:

The new generation of SAIP mixing heads: the high pressure Third Stream mix-head

The high pressure Third Stream mix-head represents the new generation of Saip mixing heads, the result of long experience and targeted research which have demonstrated that the radial type mixing in the head gives better mixing results than the axial one.

The Third Stream mix-head permits the separate injection of the blowing agent in any kind of foaming units (SAIP’s or others’), new or in revamping. Compared to other products on the market, the novelty of Third Stream mix-head is that the recycle of the third component occurs directly in the head, by components radial mixing. A perfect nebulization is achieved as well as an optimal foam mixture thanks to the direction imprinted to the flows and to the high kinetic energy of each component.

The third component is installed on SAIP mixing heads with diameter vary from 10 mm to 24 mm.

Technical characteristics and benefits:

  • Recycle in head of the third component;
  • Third component pressure adjustment (from 0 to 180 bar maximum);
  • Possibility of exclusion of the third component (manual or automatic enabling);
  • High quality mixing due to the simultaneity of the components' input in the mixing chamber;
  • Mixing homogeneity: no advance and postponement of each.

Saip hp third stream mixing head is an innovative, versatile and highly performing solution and it is rightly considered a cost-effective solution for small and medium sized enterprises for the followings:

  • it offers the possibility to retrofit existing equipment to the use of HC’s, HFO’s, methyl formate and other blowing agents;
  • it’s easy to install and to use;
  • it requires low maintenance and service.

Together with a high-pressure three-component dispensing unit, that SAIP developed in cooperation with UNDP, the hp Third Stream mixing head represents a low-cost option for small and medium sized enterprises.

The high-pressure three-component dispensing unit developed in cooperation with UNDP and a 3D section of HP Third Stream mix-head.

Face-up foaming fixture | Electrical foaming fixture | Modular foaming mould: advanced production solutions for commercial refrigeration industry.

Saip has developed several solutions for the production of refrigerated display cabinets and vending machine cabinets which improve productivity, ensure energy saving and reduce environmental impact.

Saip face-up Foaming Fixture thanks to the face-up filling technology performs better filling and foam density distribution in the cavity of the cabinet. The foaming fixture top platen is fixed while the foaming fixture bottom platen has an up and down vertical movement by means of servo-motor electrical cylinders, allowing the automatic processing of the selected cabinet model to foam. The use of Electrical Cylinders overcomes the limits of traditional systems, hydraulics or others, achieving remarkable advantages such as reduction of energy consumptions and of environmental impact because of lack of wear, maintenance not required and lack of waste oils.

Technical characteristics:

  • fixture side walls made of aluminum plate with built-in pipes for conditioning water circulation
  • plugs assembling to the fixture top platen by means of automatic system
  • plugs heating system through hot air circulation
  • width, length, depth adjustment

The face-up foaming fixture technology can be used in combination with Saip Modular Foaming Mould which allows using the same plug or core for the manufacturing of different kind of cabinet models.

Another Saip innovative solution (patent pending) is the Automatic Heating System for the plugs that allows preheating of the foaming plugs prior to the use in the process. A dedicated plant management and process control system is focused on verifying that the cabinet to process, once arrived at related plug from the pre-assembling line, is the correct one.

Overlapping & Endlapping system in the process of sandwich panel production

Saip Overlapping & Endlapping solution (panel longitudinal junction and foam-free area at the eaves) overcomes the limits of traditional methods which, according to situations, could imply: risk of rust, polyethylene strip management, in terms of the laying activity and the storage of different size stripes, production and management of waste of foam and of metal sheets, just to name a few.

With SAIP overlapping and endlapping solution, the panel is created before the foaming phase of the two surfaces with a cutting system by means of a shear and a consecutive moving overlapping system whose measurement can vary from a minimum of 10 mm to a maximum of 300 mm. After the overlap of the metal sheet, a polypropylene strip is applied at the end of the overlapping sheet so as to seal the area and prevent foam infiltration. The polypropylene strip in question has a unique measure that applies to all overlapping measures. The panel is cut using a disc that cuts the internal sheet of the panel and the foam to a certain thickness; the rest of the foam is removed with a water-jet system. The separation of the panels takes place by accelerating the panels at the exit.

SAIP overlapping and endlapping solution overcomes the limits of traditional methods allowing the advantages such as: better panel finishing, less waste of raw materials, reduction of power consumption and reduction of labor costs.
