Parts2clean Stuttgart .High Pressure wash/deburr

I remember when AGULLO supplied the first high production (220p/h) washing machine with high pressure water for wash/debur of cylinder heads in the Automotive industry in Europe . It was early in the 1980’s and the High pressure pumps power were for 600Kw. In this time not many companies in the world were able to supply high production machines and the addition of the high pressure was not frequent.

The high pressure installation engineering was a challenge. Not only the high pressure pump supplier didn’t have experience in the 5.500 hour/year continuous running of the pumps but other circumstances were added : working with recirculated water (filtration engineering) , keeping the water at controlled temperature (cooling engineering), keeping the overall noise of the installation (then at 85 dB )(noise insulation engineering), HP safety valves and HP distribution valves reliability , materials used on the HP jets and lances (mechanical engineering) , materials resistance to the HP impact for the fixtures and clamps, vapour exhaust ,vibrations transmission all along the machine,chemical detergents compatibility,flexible hose life…a lot of engineering and innovation.

For many years the AGULLO experience in the high pressure was on the top . Now , 25 years later there is a lot of companies that they say can offer high pressure wash installations.The HP pumps and accessories suppliers have more experience and the technology is better known but , is really so easy , are they selling with knowledgement of high pressure technique’s?… I don’t thing so.

Who are now the companies in the edge?

In the Parts2clean exhibition in Stuttgart I visited SUGINO , as I wrote in my before post who has a lot of experience in Japan on this Installations mainly in low production.

 In Europe we can find one small specialist: Piller in Baden-Wurttenberg(Germany) who has several HP deburr machines types with manual load or robot load ,like the CNC “Vector Jet”cabinets and dominates the deburring range of 400 to 800 bars with water or oil. Their experience comes mainly from the small mechanical components deburr at low production.They had difficulties to supply the complete process of wash,deburr.blow off , dry in one installation but step by step they are finding sollutions to do it using several machines. In Germany is considered as the main experienced supplier. Their clients are mainly germans. As particularity I can highlight that Piller  uses a CNC gantry robot on the roof of the machine moving the HP jet , keeping the part clamped on the table that can have additional CNC axis.

 

 

Another company present in the exhibition is also the german INDA-Markert of the SCHMID group. Indawas an small company with local activity in the high pressure that met Markert with experience in the German automotive market (Mercedes)and transfer washing machines. Both together are now presenting also CNC cabinets for HP operations with HP automatic tool exchange , or rotary transfers, or in line transfers. Out of Germany there are not too active ( out of Hyunday or Kia projects). They were also presenting a robot for deburring gearboxes , with automatic HP tools changer( rotary lances , V-jet , pin point jet..).

 

Of course we can not forget Dürr Ecoclean as global high pressure supplier despite his presence in the Parts2clean exhibition with only one machine for the general market ,the Cmax that I will talk about in a another post. They have the experience and globality that some others don’t have.

Another big specialist that becomes more global is the Canadian Valiant . This company was for years the competitor of AGULLO , and Centry Spray(after Ingersoll) ,and now for Dürr Ecoclean in America.

Valiant is present at the exhibition trough the Austrian TMS company ( body handling) hat now is part of the Valiant group and that will take the responsibility of the Valiant washers/deburr for Europe. The last 5 years of Valiant in USA have been successful , passing for the transfer in line , Ferris wheel supplier to be a complete partnerfor the Automotive industry ,supplying turn key installations with the handling, robot integration,washers(high pressure or robotics),deburr , leak test ,and special assembling machines and AGV transport . Their Aachen Engineering adventure is now forgotten and they seems determined to attack the European market from their new base in Austria. Is the only manufacturer that can compete with Dür Ecoclean as “global” supplier.
