Product Update
WSB MB mix motor update
Technical Bulletin
There has been a recent change to the Micro Blender mix motor. This will now be a pneumatic actuator, replacing the electric motor. The pneumatic actuator provides a more efficient and reliable mix. There are two options with the new actuator, it can be protruding on either the right or left of the blender, looking from the front. This is because, when mounted directly on a machine, there could be an obstruction to either the right or left of the blender. So when ordering a MicroBlender, please be sure to check this. Simply state in your order whether you would like the actuator mounted on the left or right hand side.

special application
There has been a rapid and steady growth in the use of long fibre reinforced plastics in recent years. This has been achieved due to their potential of combining high performance design and styling flexibility. Typical automotive applications are dashboard carriers, technical front-ends, seat shells, bumper carrier, battery trays, and spare wheel dwells. Due to the geometry of the fibres, length can range up to 25mm or more. Therefore it is very easy to “bridge” inside the WSB hopper and across the slide gate. It is very important that the slide gate used in the fibre hopper be a 3” x 6” and that the finger guard is removed.
We are also starting to create small videos on some regularly asked questions. For example, see our colour change and clean out video in the link below.

Linemaster Extrusion Control do you know?
special application
Window Profile Extrusion
Technical Bulletin
A Maguire LineMaster installation was made at a UK window frame producer on a 500 kg/h Krauss Maffei Profile line, which incorporates 2 extrusion heads and downstream inline gasket extrusion. The material blends are prepared centrally based on a mix of PVC powder, Impact Modifier, UV stabiliser, Master batch and processing aid. The blend of powders is then conveyed via a central material handling system to a holding hopper located above a starve feeder which sits on the throat of the twin screw extruder. In this application the product being produced was a 2 strand “back and front” window profile incorporating inline gasket extrusion. The front and back strand are mirror images of each other and technically should be equal in weight and dimension.

Follow mode – The POT card, when in Manual, will act as a pass through by connecting the reference voltage (0-10vdc) from the primary device such as a PLC touch screen to the extruder speed drive, so start up procedure stays exactly the same for the operator. When in Lock, LineMaster takes over the speed control.

Accuracy overview Following the recent installation of LineMaster on an optical cable sheathing line – operational data has been collected to access the effectiveness of the LineMaster system and the results have been plotted to show precisely the comparisons between line speeds, RPM and product dimensions. The large increases and decrease of the line speed (blue) can be seen as the cable drums are exchanged when they get full, the most important fact is that the grams/metre and cable diameter (brown and red) are maintained within the +/ – 0.2mm customer tolerance even during these large changes. This is due to TRIM mode tracking the capstan line speed using a 0-10v feedback signal and adjusting the extruder RPM (green) to maintain target grams/metre set by the operator.

Automatic Specific Gravity calculation
LineMaster performance on an optical cable sheathing line
When producing multi-layer blown films it is important to know the Specific Gravity (SG) of the blended materials to ensure the correct layer ratios and overall Micron gauge. Normally this calculation could be done manually, and then entered into the G2 Yield control screen. However – by entering each materials SG into the material data base, when a recipe is then created it will automatically calculate the blended SG when uploaded to the blender and LIW controller removing the risk of any human error and reducing scrap.

Gravimetric Feeders Moulding Focus
Technical Bulletin
When the MGF is used for injection moulding applications, the accuracy of the dispense is maintained by the software constantly monitoring the screw back time signal and then making adjustments to the stepper motor speed to maintain the dispense target. Variations in screw back time will always happen either due to the operator making fine adjustments to the shot weight, or as the processing parameters change naturally due to temperatures, pressures and material densities.
Contents Gravimetric Blending
The screw back time monitoring is completely automatic, the operator only has to set the Shot Weight and LDR (Let Down Ratio) percentage.

AGL-ST and custom options
02
Option 1
Option 2
Firstly the Maguire AGL-ST is a simple venturi loading system for “beside the machine” material storage such as a plastic wheeled bin. The air supply to the venturi is controlled with a 24vdc solenoid and by the fill levels set inside the MGF controller. The material is blown up the hose from the probe and into the MGF through a lightweight flexible hose to minimise effects to the load cell readings. The is a quick disconnect for easy removal of the hopper for cleaning.
Use the same 24vdc signal but this time to control a valve supplied by others. In this way, central system loaders can be used mounted above the MGF hopper and the material falls by gravity. The important note is that the no direct connections are made to the MGF hopper, otherwise the load cells cannot measure the weight of the material in the hopper. In the picture, the hose is connected to a lid which is not physically touching the MGF hopper.

Slide Out Vacuum Chamber
Technical Bulletin
Both the VBD1000 and VBD150 now have load cells fitted as standard to the vacuum and retention hoppers. This removes the need for level sensors and gives far greater control. Material consumption and throughputs can be calculated and displayed.
As many of you may have seen, our model shown during the K Show did not feature the slide out vacuum tank. This is now in production and all VBD models will have the new feature. This has many advantages, the main one being the ease of clean out for the operator. The operator removes the fastening clip and slides the chamber straight out, allowing them to clean the inside of the chamber, it then slides back to it’s original position and the clip is fastened in a quick and easy process.

VBD stock plans
VBD test data
We plan for the latest VBD-150's to be ready to ship by March. All outstanding orders shall be fulfilled and stock will be taken. MPI also have VBD 1000's ready to shipped by March.
Initial material trials with the VBD-150 have proven to be very successful. Testing is on-going and more results will be published in future bulletins. The PC trial will be run again with a reduced vacuum time (typically 15 minutes) due to the very good first batch result of 0.0085%. This will have the effect of increasing the throughput to 60Kg/h and reduce the kW/ Kg value to below 0.070.
All models shipped will be the latest design

MLS upgrade to Flexbus
There is an option built into the flexbus software to alternately operate two line cleaning valves. This was done for common material lines, “reverse line cleaning” is possible to clear any material that has overshot the “Y” branch to the machine loader, therefore maintaining a clear pipe line.
We are offering an option for the FlexBus control on the MLS pump platform which is part number OPL-FBTSC2. This is available when ordered as an option with the MLS system. As an optional retro-fit control it would be part number FB-MLS2 which also includes the pump control board.

Sweepers do you know?
Product Feature
Flake / poor flowing materials
Technical Bulletin
We are frequently asked if the sweeper can convey regrind, flake or poor flowing materials. We have many applications where the sweeper is not conveying standard granules.
The Sweeper is designed to “Sweep” only when material is being conveyed by the loading system it is connect to. It achieves this by using a sensitive vacuum switch which detects when the material loader is running due to the pressure drop in the material pipeline of the Sweeper.

G2 Latest Software
Case study Recently, our Greek distributor, MP Extruders, have worked on a project involving the use of G2 to control a line fitted with an LIW and WSB. They also installed G2 onto a windows tablet. Here is a small case study on the project:
Gravimetric Blending
“MP Extruders stands out both in Greek and international markets for the manufacturing of Blown Film extrusion lines, but also for providing integrated plastic production solutions based on technology. One of the latest solutions was the installation of Maguire’s LIW, WSB and G2 software over a WI-FI network, including the use of a Windows tablet as a terminal to control the line. Using a wireless rooter to connect WSB and LIW controllers I achieved a very reliable communication of all components throughout XC-3 mode on our Extrusion line. The response of the system at recipe downloading and processing data, are excellent and reliable. Using the system over WiFi, we avoid electrical noise from Ethernet cables. In addition you have installation freedom of your common or industrial PC or in this case a windows 8 tablet. The RD department of MP Extruders constantly explores and applies solutions for Maguire’s products for maximum efficiency and reliability on blown film applications.”

OPC driver – kepware Several of our OEM's and end users communicate to the blenders using the OPC (Open Platform Communication) Kepware U-Con Server and Maguire profile. This will work for either serial or Ethernet topologies. Generally this has been used with SCADA systems such as WonderWare or Siemens HMI front ends. More information regarding the Kepware OPC driver can be found here:Click Here
Dimitris Kotsopoulos Mechanical Engineer Owner of M.P. Extruders
Sweepers G2 Software
OPC was designed to provide a common bridge for Windows based software applications and process control hardware. Standards define consistent methods of accessing field data from plant floor devices. This method remains the same regardless of the type and source of data. An OPC Server for one hardware device provides the same methods for an OPC Client to access its data as any and every other OPC Server for that same and any other hardware device.

It is now possible to make a totally Ethernet based G2 network when using WSB 12-12 (Blue display), LIW or Touch Screen controllers which have Ethernet ports as standard. When doing so, the new G2-SK-E should be used, this plugs into a USB port on the G2 Server PC and does not require a separate power supply. If there is an older blender in the system which is still using the 6811 (Red display) controller, then a G2-ES-12 adaptor should be used to convert the serial output to Ethernet.
