     MULTI MELTERS with interchangeable pots
                     Return to Links Menu

    wenesco multi melter

    Wenesco's MU series Multi-Melters can be used to melt separate batches of product using a main melter with interchangeable pots.  The main melter nests the pot just over a convection heater, which is controlled with a remote digital thermostat. The pot and contents are easily removed from the main melter.   

    Our Multi Melters include two stainless steel pots with handles.
     

    Wenesco's 10-gallon Multi-Melter is combined with a winch to lower a stirrer into the melted compound. The Multi-Melter features quick interchangeable liners, which contain different compounds.

    Temperature is controlled with an accurate digital thermostat. The stirrer speed is managed with a variable frequency drive. The thermocouple, measuring the melt temperature, is also raised and lowered into the melted compound.

                    MODEL INJ102A-120V                                       MODEL INJ102B-240V

    Self-contained Injectors are designed to dispense controlled quantities of hot liquids such as wax, plastisol, and other compounds from any melter equipped with a heated drain. All plumbing is stainless steel.

    The heart of our injector is a positive displacement pump, which dispenses an exact amount of material in a range of 0 to 4 gallons (15 liters) per minute. Flow is controlled with a variable frequency drive. Other pumps are available up to 24 GPM

    The entire system is contained in an insulated heated chamber which is controlled with an accurate, adjustable, digital thermostat. The temperature range of the system is adjustable from 70F to 450FActual temperature and set point is displayed in Centigrade and Fahrenheit.

    An optional heated hose, as shown, will also be controlled with a built in digital thermostat.

    As an option, an electronic timer may be wired into the system to accurately control the dispensing cycle.

     

    Heated Hoses, ready for connection to the injector, feature a stainless steel braid wrapped around a Teflon core. Stainless swivel fittings permit fast connect-disconnect from the system.

    Heated hoses are available in many sizes; ask Wenesco for quote.

     

     Model DIS 10308 Thermal Micro-dispenser

    Wenesco model DIS10308 consists of a small melter with an electric valve, for accurate dispensing measured drops (62u.L) of a wax-like compound.  

    Temperature of the compound is controlled in a range of 70 to 300F with a digital thermostat. Flow is measured using an accurate electronic timer which actuates the valve. (.01 sec increments)    

    The timer is started with a footswitch, and an interchangeable nozzle is provided to direct the flow into the mold.  

    All wetted parts and the main housing are made from 304 stainless steel. A mounting bracket is located on the back of the housing. 

    Overall size: (housing) 6in dia, X 8in high.
    Tank liner: (crucible) 3in dia X 4in high (12 oz)

    Processing Guidelines & Information

    HOT MELT PLASTISOLS

    When properly compounded, Hot Melt Vinyl Plastisols have sufficient heat stability and flow characteristics to enable the processor to pour or inject the molten compound into a cold or room temperature mold.

    At the typical processing temperatures of 330F (166C) to 360F (182C), these compounds exhibit low enough viscosity to allow the plastisol to flow at those elevated temperatures.

    When cool, the hot melt plastisol is transformed into a soft rubbery substance.

    Vinyl is an excellent thermal insulator. Therefore, it is necessary to continually agitate the compound in the heated vessel. Slow positive agitation, which wipes the surface vessel, will help prevent localized degradation.

    It is necessary to keep heat distribution even and below 400F (204C).

    The plastisol, as supplied, is a low viscosity liquid. Conversion is accomplished by heating the compound until the polyvinyl chloride resin is solvated by the liquid plasticizers, then further heated to a high enough temperature for proper flow and fusion.

    Minimum temperature for fusion is about 330F (166C). Minimum temperatures for molten flow depend upon the compound, its hardness, and the process technique, but could vary from 330F (166C) upward.

    Compounds of any color, Including clear, can be utilized. Hardness ranging from 8 Shore A (fish lures) to 30 Shore A (casting molds) can be utilized.

    The plasticizers in vinyl are also plasticizers for other plastics and many materials used in paints and lacquers. Prolonged contact, with the vinyl part, can result in plasticizer migration.

    PLASTISOL PROCESSING

    Melter temperatures should be set to at least 400 F (204 C). Some users
    prefer temperature settings as high as 450F (232C), but care must be
    exercised as temperatures are increased above 400F (204C).

    Uniform heating and reasonably accurate temperature control is important.

    A setting of 400F (204C) is used to bring the hot melt to 360F (182C) before pouring.

    As the hot melt warms in the vessel, it will begin to phase from a liquid to a solid at around 250F.  At this point, it can be visually described as a lump surrounded by liquid. It will remain solid until the temperature reaches approximately 330F (166C) This is normal.

    After the plastisol reaches the approximate 330F (166C) temperature, the solid material will begin to phase back into a liquid state.

    The hot melt should be stirred during the heating process to assure more uniform heating of the mass. Additionally, the stirring of the mass will help break up the solid phase quicker.

    Excessive heat will cause degradation which is evidenced by discoloration, Continued overheating may liberate hydrogen chloride, a corrosive, noxious gas.

    OTHER APPLICATIONS

    Wenesco stainless Melters are suitable for processing paraffin, animal fats, hydrogenated oils, or any situation where solids and liquids are combined and blended at room temperature, with heat subsequently applied to melt the solids.

    Our melters are frequently used for heating and dispensing glue, adhesives, pitch, and tar, Vessels constructed from carbon steel, while cost effective, are porous, and therefore reactive. As a result, with applications where contamination may be an issue, heated stainless steel processing tanks are recommended.

    Other applications include waxes for textiles, leather, packagting, metal molding, casting and cosmetics.

    Machineable waxes, pharmaceutical waxes and automotive waxes are also successfully processed.
