Filtration Solutions Improve Safety and Reliability for Automotive Stamping Presses
Stamping machine press is one of the most commonly used pieces of equipment in automotive manufacturing. In an assembly plant, stamping presses transform sheet metals into complicated part geometries such as hoods, fenders or door panels. Stamping presses are usually characterized by both Hydraulic and Process filter applications, impacting respectively the reliability of the press and the quality of the stamped part/surface finish.
From a production perspective, stamping is a critical stage before E-coating and painting. Before stamping, the sheet metal is usually pre-washed with felt cleaning rollers to remove any solid contaminants from its surface (metal, silica, fibers). When particles remaining on the sheet metal are submitted to a multi tonne load, they create ‘marks’ on the stamped surface. These marks usually generate quality defects throughout the pre-treatment, e-coat or painting phases. The stamping press submits filters to harsh working conditions such as cyclic variations in flow and pressure.
Solutions for maximizing production, reliability and quality
Depth filtration exhibiting a Beta >5,000 filtration efficiency combined with a long service life. This filter ensures that the coolant is clean and avoids the nozzles of the low-pressure washing system to clog. The pre-wash is important as it helps avoid 'marks' on the sheet metal – the pressure applied by the press on the metal can be a few thousand tons
Athalon on-line and off-line filters ensure that the particulate contamination resulting from wear mechanisms is maintained under control even in the most severe operating conditions. Usually, on such critical equipment, there are many components very sensitive to particles > 15µm like servo-valves or variable displacement pumps. Athalon stress-resistant filters ensure that the fluid cleanliness level is fully under control to maximize the uptime of the equipment while protecting the key hydraulic components
3. Varnish and Water Removal
Removal of these elements from the hydraulic fluid, SUPRAdisc™ filter modules and Purifiers provide the best result. These two items working off-line are extremely efficient at removing varnish and water. SUPRAdisc lenticular filter modules are made of a cellulose fiber-based medium, combined with resins and additives, while purifiers rely on 'mass transfer under vacuum' technology.
Pall filtration technology applied to Hydraulics & Process applications enables Car makers or Tier suppliers to maximize the production coming out of the stamping shop:
1. Increase the equipment reliability and uptime
2. Reduce maintenance costs
3. Reduce defect rates / rework in the paint shop
