DESIGN GUIDELINES FOR ALTERING ER-SERIES

STRAIGHT - SHOT HOT SPRUE BUSHINGS

(Long and Short Styles).

The D-M-E Standard ER-Series Straight shot (Long Style) is available

in seven standard shoulder lengths with either a 1/2 or 3/4 spherical

radius and 120 or 240 volt heater.The ER-series straight shot (long

Style) can be retrofitted to suit the particular molding application.

NOTE; The 5 heater lead is standard. A 90 heater lead is available

on special request.

The D-M-E Standard ER-Series Straight Shot (Short Style) is

intended to suit the requirements of smaller injection molding

machines such as Arburg, Boy and Jaco. It is supplied with a 7/8

"A" dimension can be altered to suit the particular molding application.

NOTE: The 5 heater lead is standard. A 90 heater lead is available

on special request.

D-M-E Standard ER-Series Straight-Shot Hot Sprue Bushings

(Long and Short Styles) like the Standard E-series, are supplied with

a 0.25 extra stock allowance on the front face to permit machining of

runner profiles or part contours into that face.

These bushings feature a "reverse taper" design that originates from

under heat source, providing easier start-ups when molding nylon or

polyester. . . even during an interrupted molding cycle.

The ER-Series design can also be used when a reverse taper will

benefit a particular application. These bushings are supplied with a

0.12 diameter oriface and a 0.50 long reverse taper. The orifice

may be enlarged and the taper increase to suit.

For MINIMUM projection on runner/part, machine the runner profile

or part contour 0.25 deep into the bushing face at the centerline

of the oriface (see figures 1 and 2).

When gating into a flat surface, remove the 0.25 extra stock

allowance on the bushing face(See Figure 3). However, do not weaken

the bushing face by exceeding the 0.25 dimension.The "A" dimension

can be altered by removing stock from the front face of the 2.00 diameter

bushing shoulder.

NOTE: The 45 heater lead is standard.A 90 heater lead is available on special

IMPORTANT;

To prevent "pushback" of the hot sprue bushing due to injection pressure-and

assure a positive tapered seal with the stripper plate bushing-SECURE the

hot sprue bushing to the A-Clamping plate. A dowel or flat key installed under

the locating ring (shown) or clamping-type locating ring may be used.

The D-M-E Standard TR-Series Straight-Shot Hot Sprue bushings, like the Standard

T-Series, improves the performance of three-plate runner molds by minimizing the

length of protrusion an the runner system. This bushing features a "reverse taper"

design that originates from under the heat source, providing easier start-ups when

molding nylon or polyester . . . even during an interrupted molding cycle.

The TR-series design can also be used when a reverse taper will benefit a particular

application. The bushing is supplied with a 0.12 diameter orifice and a 0.25 long

reverse taper. The orifice may be enlarged and the taper increased to suit.

The bushing available with either 1/2" or 3/4" spherical radius, 120-volt or 240-volt

heater and a 7/8" or 1 3/8" long stripper-plate bushing to suit the application.

WARNING

DANGER

Failure to comply can result in serious injury or death:

STORED ENERGY AND HIGH TEMPERATURE HAZARDS

This product maintains molten plastic at high pressure. Use caution when

operating and servicing the system.

Physical contact with molten plastic may result in severe burns. Proper

protective equipment, including eye protection, must be worn. This product

has heated surfaces. Use caution when operating and servicing the system

to avoid severe burns. Proper protective equipment should be worn.

IMPORTANT SAFETY INFORMATION

A hot-runner system includes electrical elements and may contain molten

plastic at elevated temperature and pressure. To avoid injury, exercise

caution by reading these instructions before servicing or operating the

system.

These instructions must be passed on to the end user where they should

be read before using this product. Failure to do so can result in serious

injury or death.

Failure to comply will result in serious injury or death:

ELECTRICAL HAZARDS

Improper voltages or grounding can result in electrical shock. Use only

with proper voltage and a proper earth ground.

To avoid electrical shock, do not operate product when wet.

Do not operate this equipment with covers or panels removed.

To avoid electrical shock, turn off main power disconnect and lockout /

tag out before servicing this device. Do not connect temperature sensors to

electrical power. It will damage the product and it can cause fire, severe

injuries or even death.

If green ground wire present wire must be connected to the ground.

Do not rebend rigid leads. Rebending leads might result in damage to circuit.

Product might absorb moisture when cool. Use low Voltage or power to drive

out residual moisture before applying full power. Failure to do so may cause

damage to this product.

INSTALLATION DATA

ER AND TR-SERIES

Straight-Shot

HOT SPRUE BUSHINGS

SHADED AREAS DIMENSIONED WITH "X" MAY BE REDUCED IN DIAMETER

AS SHOWN TO PROVIDE ADDITIONAL RELIEF.

Excessive contact between the 1" and 2" outside diameters of the Straight-Shot and matching1" and 2"

bores in the mold base may result in a heat loss, causing repeated bushing freeze off. If freeze off due

to heat loss should occur, the Straight-Shot Hot Sprue Bushings may be relieved as shown.

Minimize the amount of O.D.bushing contact to the mold, leaving sufficient contact on the 1" and 2"

diameters to assure flash-free molding and proper support. This will help insulate and keep the heat

in the bushing.

PLEASE READ CAREFULLY BEFORE INSTALLATION
