Rotational Molding

F.C.I. offers its capability to develop, design and manufacture lined metal and solid plastic products and equipment through the use of Its ROTATIONAL MOLDING processes. We hope the following will provide a better understanding of rotational molding and its advantages over other molding, lining and coating methodologies.

The innovation of rotational molding equipment and technology provided new uses for free flowing resins. Whether your focus is on external aesthetics using molds, or internal linings, rotomolding should be a consideration. Utilizing computer controls to drive the machines, the products are passed through an oven and cooler for a heating and cooling cycle. Certain flow paths and temperature/time profiles are used while rotating the product on more than one axis at a time. This allows the resin to flow and form a consistent uniform wall or lining throughout the internal surface area of the housing used. Any resin available for roto- molding can be applied by varying the principles above. F.C.I.'s capabilities include PFA-Teflon, ETFE- Tefzel, ECTFE-Halar, PVDF FLEX-Kynar, PP-Polypropylene, HDPEX-High Density Polyethylene Cross linked and others.

Even distribution of resin throughout any configuration provides a seamless wall, eliminating the need for plastic welding and specially designed accesses required in dispersion coatings. The wall thickness is not limited, enabling greater structural integrity, and permeation resistance in chemical handling equipment. A smooth, nonporous bore means less friction loss and voids are eliminated, providing an ultrapure interior environment for semiconductor, pharmaceutical, FDA and other application considerations. The resin maintains intimate contact with the interior surface of the mold or containment shell. In linings, this eliminates air entrapment which can lead to local failure in temperature fluctuations and permeation as compared to adhesive bonding in dual laminate products. The physical property of the resin is maintained because stresses from hydraulic pressure and additional preparations using heat to modify finished products are not induced. This also adds dimensional stability and enables close tolerance achievements.

Engineering at F.C.I. can develop the product of need from concept to completion. Our manufacturing and engineering technical support add the assurance of meeting or exceeding your product requirements along with providing continual assistance toward your application needs. Drawings from the latest versions of CADD software and equipment are provided for your review and approval process. Following approval, a certified set is available on paper or disk giving you an engineering record of your business experience with F.C.I.

Our Quality Assurance Program maintains specific parameter controls based on your requirements and the regulations of ANSI, ASTM, ASME, MIL and ISO standards. Full traceability from order to completion is recorded. Any information concerning your order while in production or after shipment can be pro- vided with the proper authorization. The overall satisfaction of our customers through a continuing commitment to exceeding your needs is our goal!
