Plastrac Is Going Mobile -- Latest Generation of Blending Systems Puts Them on Carts for Sharing Between Multiple Process Machines

ORLANDO, FL--(Marketwired - Mar 24, 2015) - Plastrac has seen the future of blending systems and is maximizing efficiencies between multiple stand-alone processing machines. To that end, the company is launching a new line of space-and-time-saving cart-based blending systems to make additive and other changes simple, fast, and effortless. They offer extreme efficiency to custom molders on short runs. The carts can be rolled and set up quickly. Several of the new models will be on display at the National Plastics Exposition (Booth W232) in Orlando, FL, March 23-25.

Plastrac has been supplying custom single cart systems for several years and recently standardized them. The new cart systems at NPE are duplex and fully independent dual models, believed to be exclusive in the industry. The duplex dual is based on the value proposition of a single virgin feeder and two different color feeders with shared controller and blower system, typically operating independently with either manual color filling or an automated color loader. The fully independent dual system uniquely allows two different resins for double-shot machines (for applications like toothbrushes that integrate a hard plastic with a soft LSR grip). Separate hoppers on the carts facilitate easy color changes. For instance, a full dual will accommodate two natural resins, up to two additives, with a shared blower system and a control box that can manage up to six disc feeders. Operators will be able to switch colors electronically.

According to Ken Bullivant, President of Plastrac, "In recent years, calling on customers, on their shop floors, week-in and week-out, it became apparent to us that there was a need for quick changeovers and simple set-ups on short runs and to support Just In Time manufacturing practices. So, we designed our new cart systems for easy transport, quick access, and trouble-free blending shared between adjacent or close proximity machines. Our cart systems simplify so many aspects of blending and enable capabilities unavailable from single blend cart-based weigh batch systems, notably reducing scrap as high as 30% down to near zero."

The new mobile systems can be configured many different ways. Plastrac will work closely with the customer to tailor a cart to shared needs between process machines, physical specifications of the shop floor, and changeover flexibility, present and future. That includes a version of the core components of a single cart system removed from its wheels for easy fixed overhead mounting for offline blending into a drum or gaylord.

Certain features are standard on every Plastrac cart system. For instance, Plastrac has a unique blend funnel that optimizes blending even with extremely small percentage additives. It feeds into a slideout stainless steel catch hopper below the cart whose design ensures trouble-free blending of multiple streams of gravity fed pellets or micro pellets and any additives, as well as quick access and easy cleaning. Every feed hopper above the cart has an ultrasonic non-contact wireless level sensor with auto shutoff to ensure resin and additive supplies are easy to keep filled. All parts of the system are easy to connect and disconnect for fast changeovers and setups.
