On-line Surface/Auto Parts/Metal Cleaning

On-line Surface/Auto Parts/Metal Cleaning

For massive part production quantity, and associated surface finishing industries, the name of the game in today’s competitive landscape is speed combined with consistent quality and robustness.  The ‘speed’ refers to time-to-market and how early developers can create superior offers to their customers.  Any later entrants, are competitors to this first application in market place as consistent challengers. What should they do to get market advantages?

Company failures in supplying consistent parts to satisfy their customers in very competitive and thin-profit markets can cost them their reputation and decrease business success. Therefore, massive manufacturers of original and duplicate parts face economic pressure as they cannot afford manual production and testing resources, while there is an imminent need to reduce the overall handling costs.  This scratches the surface in explaining why the automation actually saves you money, time and resources – when an on-line cleaning and testing process is implemented and adopted efficiently.

An automated on-line cleanliness testing capability provides various benefits to auto/metal parts makers; coverage to detect defects and errors immediately and significantly reduces the cost of failure, saves time through its repeatability and early verification, and leverages the improved resource productivity.

Our devices which can help in your on-line cleanliness testing are: SITA CleanLine ST, SITA CleanLine Cl, SITA Cleanline ConSpector, SITA In-Line, Dataphysics PCA100 and etc.

Interfacial Rheology

Interfacial Rheology

Interfacial transport phenomena are of specific importance in the applications of multiphase fluid systems (complex fluids-suspensions, dispersions and colloids), which possess a large specific surface. Microscopically, the formation of long-range ordered structures inside the created thin films has many implications of both fundamental and practical significance. Applications of interfacial transport phenomena can be found in many areas: separation processes such as distillation, flotation, and liquid membranes; concerns of processing, flow and stability of emulsions, foams and particle dispersions; ink-jet printing; paints/coatings; wetting; etc.  To understand the dynamic process of lamination or multi-layering, which rearranges microstructures in sub-micron thin liquid films, can serve as an important tool for probing the long range interaction forces in concentrated particle suspensions and colloidal dispersions.  The dynamic surface tension and dynamic viscosity (including linear and non-linear interfacial viscoelasticity) are crucial in knowing  their creation, characteristics and stability for such systems of containing layered films.

The team of FDS/Dataphysics/SITA is a unique one in the market, with in-depth experience not only in surface science and interfacial rheology but also in manufacturing precision tensiometers and rheometers (we are not depending on external licensing as others) . 

Our devices which can help you are: OCAs, ESr-O, ODG, DCAT-LBE, T100, T15Plus, etc.
