5 PlantsRAVENRAVENRAVENPLASTICS DIVISIONINTRODUCTIONThe Plastics Division of Raven Industries, Inc. was created more than fourdecades ago with the introduction of centrifugally cast fiberglass tanks forthe agricultural and industrial markets. From its early beginnings, the Divi-sion has enjoyed substantial growth and now consists of four manufactur-ing locations, more than 200,000 square feet of production, capabilities infiberglass and Polyethylene , and a nation-wide distribution network. By the customnature of the markets we serve, this infor-mation is meant to be representative of ourproduct line.

7 It provides all of the mechanical strength necessary for liquid storage plus the superiorchemical resistance capability of a high resin-to-glass ratio wall utilizing centrifugal force to combine resin and glass, the Raven process provides tanks with adense uniform wall laminate capable of a 70% resin content. For all practical purposes, the entirewall becomes a resin-rich, chemical-resistant barrier that can be custom designed for specificrequirements ranging from the storage of corrosive chemicals such as hydrochloric acid and sodi-um hydroxide to food grade Raven spin cast tank is produced inside a smooth metal cylinder.

8 First the end section, whichis sprayed up in a separate mold, is inserted into the cylinder at a point determined by tank capaci-ty. This flexibility allows Raven to manufacture a variety of sizes without changing tooling. Forexample a 32 diameter tank can be made to hold any capacity between 100 and 300 gallons byadjusting the distance that the head is placed into the mold. After the end section has been located, sidewall construction begins by applying a 10 to 15 millayer of resin coat or gel coat to the spinning mold.

9 This provides the tank with its desired color andthe distinctive Raven exterior backbone of the tank, the structural wall and corrosion barrier, is constructed next by combin-ing chemical resistant resin with chopped strand E glass for strength. Chopped glass, either inmat or roving form, has been selected to minimize potential wicking problems sometimes associat-ed with other resin saturated chopped strand reinforcement is introduced to the mold in layers andthen rolled to remove trapped air bubbles to insure a dense uniform laminate.

10 Thisprocess is then repeated with each additional resin/glass layer to meet the design section is inserted into position determined by desired waste Water treatment 10-15 mil layer of pure or pigmented resin is applied to the mold mat or chopped "E" glass is added to meet design mils of pure resin is applied to the inside mat is placed into themold on top of a layer of plain orpigmented mold CASTING THEPROCESS page 2 of 2 SPECIFICATIONS:Centrifugally cast tanks manufactured by Raven are designed to meet or exceed the strength requirements of ASTM catalog tanks are built to hold liquid with a specific gravity of at a safety factor of not lessthan 10:1.
