|
 |
 |
|
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 450F. Actual 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) Power: 120V, 100W |

Stirrers are available with
your choice of conventional
propellers or “side wiping” propellers
that clean the melter's wall
during the heat cycle.. The entire stirrer is easily removed from
the melter for cleaning or service. Stirrers for larger melters and
higher torque are quoted to requirements. Variable speed
control is available for most stirrers. |

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 330°F (166°C)
to 360°F (182°C), 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
400°F (204°C).
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 330°F (166°C).
Minimum temperatures for molten flow depend upon the
compound, its hardness, and the process technique, but
could vary from 330°F (166°C) 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 450°F (232°C),
but care must be
exercised as temperatures are increased above 400°F
(204°C).
Uniform heating and reasonably accurate temperature
control is important.
A setting of 400°F (204°C) is used to bring the hot melt
to 360°F (182°C) before pouring.
As the hot melt warms in the vessel, it will begin to
phase from a liquid to a solid at around 250°F. At
this point, it can be visually described as a lump
surrounded by liquid. It will remain solid until the
temperature reaches approximately 330°F (166°C) This is
normal.
After the plastisol reaches the approximate 330°F
(166°C) 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. |
