Large size and Endless O-Rings in various compounds, produced with an innovative step-molding method. (www.oringone.com). Norsok M-710 ed. 3 approved materials available. The OringOne history begins back in 2002 from an experimental project born to create a production system, that allows to produce O-Rings with non-standard dimensions, in series. The global market requires large diameter O-Rings, that due to the always higher performance requests cannot be accepted if produced with traditional methods like hot jointing, or using several glues. Because of this OringOne worked on a special production method investing money, experimenting, designing and realizing brand new machineries, tools and procedures, completely new and never known before, in order to guarantee the top-end quality standards required by the industry. The operation basics of our productive process are designed on a traditional compression molding method, that guarantees the reaching of the best mechanical performances. However, we have invented, designed and engineered special machineries and molds, totally built by the OringOne Technical and Production departments and in a very innovative environment where everything is managed and guided by specialized operators and special software. The advantages of our production system are: - No I.D. dimensional limits; - No molds costs; No minimum order required; - Mechanical performances comparable or better than O-Rings made by traditional system (compression and injection molding); - Competitive prices; - Very fast deliveries; - O-Rings customization in size and compound; - Extreme fast turn-around thanks to our Xpress service delivery system. OringOne produces also other profiles like Delta-Rings or U-Rings, in order to fulfill the always growing demand for specialties.
