Satori Seal is an ISO 9001:2008 certified company and adheres to thorough quality inspection procedures in a state-of-the-art quality control laboratory equipped with the latest in measuring and test equipment. We perform a 2nd inspection, in addition to the factories inspection, on all incoming parts to assure they meet the design specifications every time before they ever reach our customers. Satori Seal strives to assure confidence in our customers by consistently providing quality parts.
Satori Seal inspects 4 features on the sample in our quality inspection process, a visual inspection to ISO3601-3, measure to applicable standard or drawing, measure hardness (durometer) to ASTM D2240/D1414 and verify the compound.
Samples from each lot are pulled at random per ANSI/ASQ Z1.4, Sampling Procedures and Tables for Inspection by Attributes to an AQL level of 2.5. ANSI/ASQ Z1.4 is a widely accepted sampling method available through the American Society for Quality, www.asq.org.
All samples are inspected for surface imperfections per ISO3601-3, Fluid Power Systems -- O-Rings -- Part 3: Quality Acceptance Criteria. Excessive surface imperfections such as flash, off register, flow marks, non-fills may hinder the O-rings ability to seal.
Critical dimensions are measured samples from all incoming lots. Satori Seal uses state-of-the-art video measuring machines and other measuring devices to assure all parts meet the dimensional specifications and drawings.
Elastomers come in various hardness' from soft, 20 Shore, to very hard, 90 Shore. Hardness can affect sealing and coefficient of friction of the seal. We check the hardness to ASTM D2240/D1414 using Instron durometer gauges on conveloader stands to assure accurate and consistent readings.
With many compounds being black its often difficult to distinguish one material from the next. At Satori Seal we identify our compounds with a Fourier Transform Infrared Spectrometer (FTIR). With the FTIR we can confidently identify our compounds. With the FTIR we can easily tell the difference between Nitrile, EPDM, Chloroprene and other compounds.
