Secondary Operations Now Available
United Plastics Technology has designed and built a versatile stamping and punching machine to facilitate evolving requirements for secondary operations. This is the second punch for such operations as punching holes, shearing parts and notching. The new design focuses on LEAN principles such as fast changeover times and reduces wasted motion therefore increasing productivity

New Plastisol
Several new dip tanks have been installed to accommodate several new color requirements. The latest "standard" colors are Serious Gray, Lazy Gray, and Matte Black. Other colors and textures are forthcoming. Several Softex(tm) materials are in the works. This material is ideal for grips and coatings requiring a soft touch with aggressive texture.

New Programmable Logic Controller
The brains of all automated and semi-automated UPT machines is the PLC. Allen Bradley has been the PLC of choice for UPT and many other factories. This is a very good and reliable PLC and will continue to be installed in equipment when requested.

PLC technology and programming software continues to evolve in an exponential fashion. Because of this (and other reasons) UPT recently converted to Wago I/O as a standard PLC. There are many reasons for this change

  • The 750-841 processor communicates via Ethernet
  • Components are modular. Replace only I/O that fails not the entire PC
  • Spring loaded connections versus screw terminals
  • Costs
  • Programming software features
  • Availability
  • Support

    In our opinion there seems to be a definite migration to Ethernet as the industrial buss of choice. The new PLC communicates via Ethernet. This allows all electronics on the machine to use the same addressable, low cost, network. In addition, most of our machines are shipped with enhanced HMI controls that are placed on the end users LAN. In most cases, remote access from the factory (or anyone else on the Internet with proper security credentials) can easily be achieved through the Internet. Communications with servo systems, the HMI, the LAN, and other nodes is made simple and can be maintained by most IT departments.

    Although we were skeptical of the spring loaded terminal connection a few years ago when we began using them on Wago terminals, we quickly learned that these electrical connections are far more dependable than traditional screw connections.

    Heated Dip Tanks
    It's been a long time coming! In keeping with our relentless efforts to build LEAN systems, we have added the heated dip tank to our product line. In a recent study over 78% of hot dip molding and hot dip coating rejects are within the first few hours of production. The study found that the most common problem was the inherent problem of heat transfer to the plastisol from the process. Unless an operator is on top of things, the process will not get adjusted to compensate for this and the result is a gradual increase in build or wall thickness through the production run. This not only wastes material but can be cause for rejected parts.
    Another common problem is the inability to achieve enough build when starting with ambient temperature plastisol.

    The heated dip tank allows the process to start at the desired and controlled elevated temperature. We recommend total temperature control for critical requirements. This means agitation and cooling jackets must be added to the tank. These features were introduced years ago by UPT.

    Yaskawa Logo

    By now you are aware of UPT's dedication to providing technically advanced equipment to meet demanding dip molding and dip coating requirements. In about 1998 UPT began using servo systems where AC motors could not meet precision positioning applications such as dip stations. First the Allen Bradley Ultra series was used. To make use of newer features and obtain local support we began using the Indramat servo systems in 2000. Now, since Indramat has changed its marketing philosophy and reduced technical support availability, we were forced to look for alternative motion control. This turned out to be a hidden blessing when we found Yaskawa. Yaskawa systemThe first Yaskawa system was installed in 2006 and will become our standard motion control system. In addition to fast and dependable support, we are impressed with the programmability of these drives. Ethernet communication is standard and fits in with our recent migration to Ethernet as an industrial network.

    Yaskawa components have proven to be very available and support has surpassed our expectations.
