Metering and mixing systems by KPD are capable of processing multi-component media such as epoxy resins, polyurethanes and silicones. Depending on the intended application or the requirements, they may be equipped with either piston or gear pump technology. For this purpose, there are different basic configurations available which feature a modular design and may therefore be configured specifically to your demands.

kpd quality standards guarantee highest precision and repeatability - even in fully automated production processes. Metering and Mixing technology by KPD is used in various industries such as the aerospace, electronic, wind turbine, and household appliance industry, to name but a few.

Standard Features

• Metering Pumps: Electric inverter driven gear pumps
• “Metered” or “Operator Controlled” shot size selection
• Service indicator LED
• Controls:
  • Integrated PLC control with HMI touchscreen and variable ratio adjustment
  • Adjustable flow rate
  • Anti-gel automatic purge timer
  • Either foot pedal, hand held trigger or remote start options available
  • Recipe Function" to allow up to 50 pre-set shot sizes, flow rates, and ratios on LiquidFlow 30M

  • Resin dispensing

    A resin dispensing system is a technical installation to process casting resin for the purpose of filling, sealing, covering or soaking technical parts, especially in the field of electricity and electronics like transformers, LCDs and other devices of various size.

    Due to progressing miniaturization and introduction of electronics into new areas, quality requirements for the parts are rising, and thus the quality of dispensing must be increased as well. To obtain the required quality, on one hand, the resin system has to be developed and optimized accordingly. On the other hand, the resin dispensing system has to work more and more precisely to obtain best dispensing. Because of continuously increasing cost pressure, casting devices must be capable of increased quality, while also becoming faster and more reliable.

    Requirements for good dispensing[edit]

    First of all, by dispensing, electrical and electronic parts have to be insulated reliably and penetration of moisture has to be excluded totally. Very often heat has to be conducted out from the part properly, an attribute that can be improved by the choice of an appropriate resin e.g. epoxy, polyurethane or silicone.

    Process steps in a dispensing system[edit]

    

    Schematic illustration of a resin casting system

    In a dispensing system the following processes have to be performed:

  • Conditioning of the resin mix
  • Material transportation
  • Metering
  • Mixing
  • Casting

  • A good resin dispensing system provides high quality casting of the same high standard even during long series in mass production.

    Conditioning[edit]

    Several properties of the resin mix, with or without filler material, one component or two components (resin + hardener), are crucial for the quality of the product:

  • Even distribution of the fillers (no settling)
  • Elimination of air and moisture
  • Constant, often elevated temperature to maintain low viscosity

  • Even distribution of the fillers without setting is maintained by ongoing stirring.

    Air and moisture are eliminated by evacuating the material tanks.

    Elevated temperature is reached and maintained by thoroughly controlled heating of the tanks, the material feeding lines, the pumps and metering heads. In filled, complex resin mixes conditioning is especially crucial for the quality of the product.

Options

• Digitally controlled heating to reservoirs, pumps and hoses
• Electric agitation to material reservoirs
• Electronic low-level sensing to material reservoirs with visual and audible alarms
• Stainless steel wetted parts to protect against corrosion
• Hardened parts to protect against abrasion
• Ultra-high precision gear metering pumps for low viscosity or small shot applications
• Nitrogen purge facility to material reservoirs
• Vacuum degassing to material reservoirs
• Bulk feed transfer pump/accumulator facility directly from suppliers containers
• Air nucleation system for foam applications
• Rotary/Static disposable mixing option (electrically driven)
• Automatic material recirculation system to help keep fillers in suspension
• "Recipe Function" to allow up to 50 pre-set shot sizes, flow rates, and ratios on LiquidFlow 30A
