Extrusion International 6-2022

23 Extrusion International 6/2022 “Triple-Play” in Sheet Extrusion Machinery Maintenance Program for Flat Dies, Chrome Rolls and Feed Screws  Processing Technologies Inter- national (PTi) announced the release of its next generation flat die servic - ing system – uCAMS™ (Universal Cleaning Assembly and Maintenance System). Introduced in 2021 the origi- nal uCAMS™was developed to be the foundation of any offline die mainte - nance program, serving as a single manifold flat die servicing system capable of accommodating a variety of die widths. An enhanced design evolving from the original concept (patent pending) has brought even greater effectiveness to servicing flat dies with the upgrade for main - tenance of chrome rolls and feed screws, called uCAMS™ Plus. This en- hanced design transforms the func- tionality of the flat die service system into a multi-purpose “triple-play” for sheet extrusion related critical com- ponent maintenance and service, un- matched throughout the industry. Mobility, ease of use by a single op- erator and safe accessibility contin- ues to be a significant advantage of PTi’s uCAMS™. All previous features included in the original uCAMS™ have evolved into the newest gener- ation including a hand wheel mecha- nism for splitting flat dies and trun - nion supports coupled with rollers that permit rotating die halves 180 degrees with ease (See picture 1). Available in three models – 1500S, 2000S and 2500S, uCAMS™ accom- modates servicing flat dies ranging from 710 to 2,500mm widths via its unique adjustable trunnion supports, eliminating the need for multiple, width-specific carts and/or trunnions. This unique design feature allows uCAMS™ users to maximize appli- cation flexibilities by permitting ef - fortless width adjustments to take place via the turn of an adjustment wheel, thereby allowing for precise placement and alignment of the die in the trunnion upright cradles that are integral to the unit. Fur- thermore, digital width position indicators coupled with special threaded mechanisms prevent unwanted position changes from occurring and accommodates a variety of die widths to be ser- viced with quick and easy set-ups. Sold as an add-on upgrade to the base system, uCAMS™ Plus trans- forms into a servicing sta- tion for chrome rolls and feed screws, increasing the pur- pose of the system threefold. With the addition of special uCAMS™ Plus components, the system is converted for the purpose of servicing chrome rolls and feed screws (See pic- ture 2). uCAMS™ Plus upgrade is comprised of two (2) pairs of A- frame and feed screw roller support assemblies, each of which features stowage cradles that keep the com- ponents organized when not being used. By mounting the A-frame sup- ports via means of toolless quick-pins to the upright die trunnion support cradles of the uCAMS™ frame, the unit is now able to service chrome rolls. Additionally, the A-frame sup- ports feature recessed bronze rollers used to protect the chrome roll jour- nals from damage when rotating in the supports during service activities. Similarly, by mounting the feed screw roller assemblies onto the A-frame supports via toolless quick-pins, the unit is easily converted into a feed screw service station. The maximum weight limits for uCAMS™ service components are 6000 lbs. for flat dies and chrome rolls and 2000 lbs for feed screws.
