Hot Sprue Bushings
Diversity
Depending on the application, a suitable bushing can be selected from one of the following D-M-E Hot Sprue Bushings :
Straight Shot
Gate Mate
High performance Nozzles
Thermag
Featuring an unrestricted
straight melt channel made of
wear resistant, hardened
steel, the Straight Shot is
often used for commodity
materials. The Pico and the
Extended Pico Straight Shot
are provided with a high
performance cast-in heater
and are used successfully
with engineering materials
requiring a tight temperature
control, like PC, POM, PA,
PETP, etc.
Gating is of the sprue type.
The vast Gate Mate family
features a melt channel with
high heat conductivity,
allowing larger shots with
minimal gate vestige due to its
point gate tip. A wide variety
of melt channels and tips is
available in various
geometries. The tips are
made from either nickel plated
beryllium copper or a unique
high wear resistant material
combining extreme hardness
with high thermal conductivity.
Gate configurations other than
the point tip are also available,
e.g. the thru hole tip which
eliminates potential flow lines.
The CIA High Performance
Nozzles with cast-in heaters,
developed exclusively for
D-M-E , can be used for all
applications, especially
engineering grade resins with
a high degree of crystalinity.
In combination with a band
heater they are also suitable
for direct part gating in single
cavity molds. The High
Performance Nozzles are
delivered with a seal ring. The
radius has to be made by the
customer.
The Thermag is an all steel
bushing designed for direct
part gating, especially
qualified for bulk materials,
like PP, PS, PE.
Multiple gate nozzles
Autonozzles
Osco® single valve gate nozzles
Micro single bushings
The Multiple gate nozzle is suitable
for multiple gating of small parts in
multiple cavity molds or larger parts
in single cavity molds. Providing up
to 6 points of sprueless injection,
located on a small circle, this self
contained round manifold with HotOne type probe gating offers
optimum gate cosmetics. Two gate
configurations: point gate and thru
hole whereas the point gate type is
also available in a wear resistant
version for abrasive materials.
Each gate is fed through a micro
Hot-One nozzle with its unique
thermal heat. To obtain a better
insulation titanium support and
spacer rings are used.
For direct gating of large and/
or deep plastic parts. Any
length available between 200
and 800 mm. Two standard
tips are available: point gate
and thru hole type. Suitable
for all unfilled plastic
materials. Maximum shot
capacity 10.000 cm3/sec
(depending on material, part
geometry and flow condition).
D-M-E Osco's single valve gate
nozzles, full body type and
bodyless type, are designed to
provide more flexibility and better
results in any molding application.
With an externally mounted
cylinder it is the most trouble free
and easy to install system
available. The single valve gate
offers a unique external pin
adjustment to simplify machining
and mold assembly requirements.
Also a replaceable pin seal
eliminates leaks and the original
pin guide eliminates gate wear.
The system's shaft-driven 1:1 ratio
provides longer components life
and safer operation
D-M-E's Micro single bushing
provides a solution for direct gating
where space is limited. Near the
gate, if fits in a boring of 17 mm
diameter only. It features an
excellent melt temperature control
with two independent zones
possible. The design of the cast-in
heater at the gate end is unique,
reduces heat losses tremendously
and guarantees temperature
uniformity. Two gates are possible:
point gate and thru hole type. The
point gate is supplied in a standard
and a wear resistant version. Most
kind of engineering plastics have
been successfully injected with the
D-M-E Micro single bushing.

to eliminate conventional cold sprues
to improve part quality
to reduce cycle time
to reduce shear, stress
and pressure loss
to improve performance
to increase productivity
to save energy
for large shots
for difficult materials
for materials savings
for shot capacities up to 1000 gr.
for a low cost per gate
for a uniform temperature profile
Benefits
Cast-in heaters for
the ultimate heat profile
The Straight Shot was designed to remove the
superfluous direct gate on single moldings.
The melt is guided through a straight central
channel and without deflection directly to the
cavity.
The entire heater of the Pico and Extended Pico
Straight Shot is encapsulated in copper and is
covered with a stainless steel sheath for insulation
and protection. Copper is used to give a better
heat transfer.
The channel is made of hardened steel and is
wear resistant. An optimal heat separation is
provided by the minimum contact surface between
the bushing and the mold.
Distributed wattage allows heat to be precisely
placed for even temperature control. The heater
casing gives exact heat and provides the ultimate
heat profile.
The internally grounded thermocouple location was
chosen for optimum heat monitoring and control.
Heaters with integrated thermocouple guarantee a
uniform temperature along the flow channel. Thus
a thermal overstressing of the plastics melt is
impossible.
Thermocouple
Further advantages of the Straight Shots are the
small dimensions, easy modification of the gate
opening and a variety of four types: Standard,
Mini, Pico, and Extended Pico Straight Shot.
The Standard and Mini types use optimized square
coil heaters, the Pico and Extended Pico Straight
Shot are provided with a copper cast-in heater.

Length to cut off
The D-M-E Straight Shot is designed for direct part
gating or feeding runner profiles. It is supplied with a 1.5
mm gate opening.
In case the gate opening is insufficient, the diameter can
be enlarged. Thereby the front side of the bushing is
reduced, fig. 1, detail X. Body and sprue bushing should
be reduced by the same length.
The cost per gate is at its lowest because some gate
vestige is admitted and also a circular mark is accepted.
The Straight Shot can be exchanged for already installed,
conventional sprue bushings on almost any injection
mold.
Changing color is no problem.

Benefits
Special uses
The Gate Mate incorporates a high thermal conductivity
central melt channel in a steel housing or body.
The melt channel is made of nickel-plated copperberyllium for general use, or of conductive high wear
resistant material for plastics with abrasive fillers. The
melt channels or tips can be replaced and one steel body
can accept various tip styles. This design allows
considerable flexibility. Many different tip and body
combinations are available.
With its full length beryllium copper tip, the Gate Mate
has been extensively used on most materials except
glass filled resins. The insulated tip can be positioned
into the gate with a minimal mark on the molding.
If the injected plastic is particularly prone to weld lines,
then the usual point gate tip can be replaced by the thruhole tip. Glass filled or other abrasive materials can be
handled by the hard wear resistant tip with its exceptional
combination of hardness and thermal conductivity.
The fitting surfaces of the bushing in the mold represent
an optimal trade-off between mechanical strength and
heat losses. Due to the particular shape of the head,
heat losses are limited. From near the gate to well inside
the body, an insulating layer of plastic material
guarantees a uniform temperature up to the gate.
Independent thermocouples are strategically located and
easy to replace.
D-M-E ’s new cast-in heaters can also be fitted on the
Gate Mate. Combined with the hard wear tip, the Gate
Mate family represents a big step ahead in technology.
They are easily installed in new and existing molds.

Mini Gate Mates - GMB
Mini Gate Mates
How to order
The Mini Gate-Mates are ideal for cast cycling single
cavity molds. The compact design permits shorter overall
stack-up of the "A" side mold plates. The Mini Gate
Mates are provided with either a square coil heater or a
cast-in heater. Thermocouple position provides better
heater control and the overall body design improves
thermal insulation.
Types
To order a complete Mini Gate Mate, select the required
body and heater type which results in finding the correct
reference number.
Remarks
Tip is made of copper-berylium and is not recommended for
abrasive materials. For applications involving highly
abrasive engineering grade resins, contact D-M-E.

Benefits
Special uses
The Thermag, a full steel single bushing, was primarily
designed for single cavity molds with direct part gating of
commodity plastics. Its sharp hardened torpedo tip
leaves on the plastic part only a minimal gate vestige,
about one-third in height of the gate diameter. Beside
the excellent cosmetic appearance of the gating, the
Thermag is also very compact with its maximum outside
diameter of 35 mm (band heater excluded).
The Thermag uses a probe cartridge heater similar to
that used in the D-M-E Cool-One System. This well
proven concept found its way back to single bushings.
Hardened body and torpedo give a long endurance life
also for abrasive materials.
Particularly suited for bulk plastics, reinforced or not.
The closed chamber option is recommended when a
witness ring on the plastic part is acceptable. The open
chamber avoids the witness ring and is recommended for
optimum gate cosmetics. Also applicable on ribs, bosses
and curved faces.
The Thermag is made of hardened wear resistant steel.
Its unique torpedo is specially designed for a smooth
molten plastic flow.
Two heating zones:
One cartridge heater in torpedo and one heater band for
the distributor cap for perfect heating and control.

Other benefits are a perfect balancing of the flows,
associated with a simplified mold design and
construction.
The various MGS combinations with different nozzle
lengths offer full design flexibility.

BHF
L
It is possible to select a nozzle with 2, 3, 4 or 6 gates on
a pitch circle of 38 or 60 mm diameter, and different
probe lengths.
Each gate is fed through a Micro nozzle with thermocouple, which results in a perfect thermal regulation of
each gate. Therefore the system features a uniform heat
distribution and temperature profile throughout.
To obtain a better insulation, titanium distance rings are
used.

Special uses
Although designed for multiple gating of small parts in
single cavity molds, the multiple gate nozzle is also
highly recommended for multiple point injection in one
large cavity where balancing of the melt flow is a
problem.
Positive results with difficult applications like thin-walled
(0.6 mm) glass filled PPS and glass filled PBT parts have
been obtained.

for easy maintenance.
Flexibility
D-M-E has developed the so-called "Autonozzle" for
single applications with Hot Sprue Bushings to produce
very large parts, especially for the automotive industry.
The nozzle consists of a body and standard interchangeable tips, of which the geometry has been computer
determined.
The Autonozzle is heated by several band heaters,
which can be relocated depending on the length of the
nozzle and the plastic material to be used.
Field-tests have proven the implementation of the
Autonozzle very successful. The ratio between price and
performance is also favorable.
For applications with abrasive materials, nozzle and tip
can be protected with a special coating.

Special uses
How it works
With its wide range of gate diameters, the Osco® Single
Valve Gate Nozzle is suited for medium size to very
large molded parts, in most plastic materials, unfilled or
filled. The large melt channel allows the use of shearsensitive resins. The two powerful band heaters provide
the possibility of a 2-zone accurate temperature control,
necessary for materials with a sharp melting point. With
the choice of a full body or bodyless tip the heat transfer
at the gate can be adjusted for both amorphous or
crystalline materials.
The linear actuation of the cylinder is directly transferred
to the valve pin thru a drive shaft, which opens and
closes the valve pin as the cylinder is energized in one
direction or the other. The motion of the valve pin is
accomplished without using any kind of lever arm, which
would greatly multiply the force of the cylinder, causing
premature failure of the components. Since the system
uses a 1 to 1 ratio the force to which the valve pin is
activated is always safe and known.
Adusting the valve pin:
The externally mounted cylinder is piloted axially with
the drive shaft, and the mounting hole is slotted allowing
the cylinder to be rotated in either direction. While
maintaining the cylinder energized and locked in the
closed position the valve pin can then be easily adjusted
by loosening the mounting screw and rotating the
cylinder one way or the other. This unique feature totally
eliminates the need for delicate machining and
positioning of the components as required with other
systems. The cylinder is supplied with a dial showing the
position of the valve pin allowing you to see where the
valve pin is and how fast the valve pin is opening and
closing.

Micro Single Bushings - MPP/MDO
●
1)

T°
The advantage of this Micro system lies in the application of
the new D-M-E designed and patented heater element
generation. These heating elements have a special multilayer design which results in 60% less heat losses to the
mold. This allows for a lesser wall thickness for the same
heat power as e.g. in conventional cast-in heating elements.
Due to a superior far more homogenous temperature
control, reacting promptly on temperature deviations in the
bushing, this system is also most suitable for use on difficult
raw materials.
Special uses
The superiority of this new heating system has been largely
demonstrated and proven to the users by extensive
successful applications of engineering materials such as:
Delrin, Trogamid, PC, Ryton R4, Desmopan, etc. ....

The Micro Single Bushings are especially designed for
extreme conditions. Both bushing and heater are designed
for very limited space. A comprehensive range of different
bushings with point gate tips, respectively thru hole tips, as
well as different steel qualities provide the user a full
spectrum of design capabilities. A new single bushing with
supporting head and exchangeable tip was designed for the
direct part gating in narrow access cavities.

The figures 1), 2) and 3) explain the differences with conventional cast-in heater elements and illustrate typical conduction
heat losses between inner (T1) and outer (T2) surface of an
heater sheath. These losses influence the cooling requirements in the mold, and the energy supply, required for a
constant temperature in the melt.
The cast-in heater element 1) against the double layer type 2)
shows a double heat loss. Compared to the D-M-E heater
elements of the newest generation, of a multi-layer type, there
is a factor 5 of difference.
The combination with the correct body material 3) ensures the
fastest control and lowest overshoots, because the major part
of the energy supply will be directed towards the heating of
the melt.
This means that to maintain a temperature of 250°C at
bushing tip, only ca. 270° C are required at the external
surface of the bushing, compared to 290° C or even 350° C
when using conventional heater elements. Due to the
consequently lower energy consumption of the heating
system a definitely higher life expectancy of the heating
elements can be expected. This is an advantage that should
not be underestimated either.
The termal insulated heater

The key to succes in heating runnerless systems for extreme
specifications.
The cast-in Micro system heater elements are, due to their
multi-layer construction today's most performant system for
heating nozzles on the market.

Process Data Sheet
These maximum melt discharge flow values apply to the D-M-E
bushings only and were obtained by using mathematical models
and through experience. Three representative unfilled resins were
considered, and it was assumed that the molded part was not a
limiting factor by its geometry or e.g. wall thickness. The constraints limiting the flow through the bushing and the gate were the
commonly accepted peak values for the shear rate and stress, the
melt temperature and its increase by friction, and/or the total
pressure drop. The actual results obtainable with the D-M-E Hot
Sprue bushings depend on a large variety of factors on which
D-M-E has no control like type of plastic materials, fillers, mold
design, injection machine, molding parameters etc...
Therefore, D-M-E is giving this information only as general
guidelines and no warranties are expressed or implied. In case of
doubt, D-M-E will be pleased to give any advice and assistance.

Regarding the shot weight
These maximum shot weights per probe or nozzle are
given as an indication only, assuming normal injection
times, favorable molding shapes and wall thicknesses.
These maxima may be lower for instance in case of
fast cycling molds, for thin walled products, or even
higher in cases where long fill times are admissible.
