General Arrangement (cont.)

8. Table Lever. When pulled towards you

the

table will rise

to

the

upper limit. A

further

application

of

pressure will lock the table in this po

si

tion. During forming

the

table complete

with

mould

is

lifted intothe

hot

plastic and locked in place

to

ensure a good vacuum seal. At

the

end

of

the

cycle

the

table

is

returned

to

the

lower

po

sition by pushing

the

handle

back

and away.

NOTE

: A mechanical interlock designed

to

prevent a mould being raised

into

the heating elements stops

the

table being raised unless

the

heater box

is

fully

back

.

9. Control Panel.

13. Heater Standby Level (Power

Saving

Feature). The 300XQ

is

supplied wi

th

fast acting heating element

s.

This means

that

when

the

heater

is

not

actually heating plastic

the

power

can

be turned down.

As

the

heater

is

moved

from

the

rear position

the

elements begin

to

heatup

to

the

set powerlevel.

For this feature

to

work effectively

the

power level

at

rest

or

standby must be s

et

to

approx.

30

%.

Fo

r

continuous usage

the

standby level may be set lower.

Fo

r infrequent us

age

it

may be required

for

the standby

level

to

be set higher. For non-

time

critical

uses

the standby level can be set

at

about

10

%.

Although the

plastic may take a

few

extra seconds

to

heat,

the

overall powersaving will be substantial

Safety Notice:

It

is advisable

to

monitor

the

heatingstage

by

makingfrequent observations.

Neverleave

the

machine unattended when actively heatingplastic.

14

. Heater Zone Controls. The 300XQ heater

is

divided

into

4 zones

as

shown by the diagram (12) on

the

control panel.

This

is

to

allow

the

user maximum flexibili

ty

especially when producing mouldings from difficult

moulds or difficult plastics.

It

is

usual

to

turn the centre zone 1 down slightly becau

se

it

gains extra heat from

the other zones surrounding it.

The

back

zone

3 also tends

to

stay

hotter

than

the

front

zone 4 because

the

rear

of

the

machine

is

heated by the heater when

it

is

not

heating plastic. A

key

feature

of

quart.z heating

is

Page

9

the

response time

for

changing

to

different power levels. The zone controllers are highly accurate

and

keep

the

element power level within

1%

of

the

requested setting. Beginners

to

vacuum forming will quickly become

accustomed

to

setting

the

zone controls

for

best results.

15. Digital

Timer

. When producing a quantity

of

mouldings using

the

same mould and plastic

the

heating

time

will

be

nearly constant

for

each one.

In

this

case

the

timer

can

be used. Record

the

heating

time

for

the first

moulding then set

the

timer

(in seconds) using the

UP/

DOWN

buttons

the

buttons. When

the

heater

is

pulled

forward

the

timer

counts down from

the

set

time

and sounds a buzzer when zero

is

reached. The heater

is

then pushed back. The set

time

is

stored until

it

is

altered.

If

you don't want

to

use

the timer, set

the

time

to

zero.

The

timer

has

built in safety features.

If

the

heater

is

forward

for

more than 2 minutes

after

the

timer

has

completed the set

time

the

heater will switch

to

the

standby setti

ng.

If

the

heater

is

not

returned

to

the

standby position aftera

further

2 minutes then the heater will

turn

off

all power

to

the

heating elements.

16. Vacuum Gauge. This

is

situated on

the

top

RHS

of

the

front

panel and gives indication

of

the

vacuum level

achieved at

the

table mould area during moulding.

It

is

usual

to

expect approx

22

"

Hg

I -750mbar

of

vacuum.

If

such

levels are

not

achieved check your mould I table configuration & clamp I plastic

seal

ing.

Reducing Windows

Reducing windows allow

the

use

of

smaller sheet material

for

smaller mouldings. Reducing windows allow

for

better

sheet utilisation.

To

fit

the

reducing

window

.

1. Lift

the

clamp frame.

2.

Place

the lowerreducing window plate on

to

the top

frame aperture

so

that

the corner locating

screws are aligned.

3.

Place

the

top

reducing window plate on the underside

of

the clamp frame. There are folded sections

on

the

front

and rear. The rear edge

has

the larger return and wraps completely around

the

clamp

frame bar. The

front

fold

is

smaller and returns against the

front

clamp frame

ba

r.

The fixing bolt

is

fitted

F.A.Q.

How

long

does

It

take

to

heatthe

plastic

sheet?

This depends on which material and thickness

is

specified.

How

do

I

know

when

the

plastic

is

ready

to

form?

Generally speaking

it

is

necessary

with

any new material

to

establish

the

correct heating cycle. Plastic

is

ready

to

form

when

it

becomes soft and pliable especially nearer

to

the

clamping frame. This

is

known

as

glass

transition temperature (Tg). Once you have established

the

time

you

can

set

the

heater

timer

for

accurate and repeated heating cycles

Why

is

the

plastic

webbing

on

the

mould?

Material

is

too

hot

.

Insufficientvacuum.

Excess

of

material.

Use

reducing windows.

Poor mould design.

Why

can't

I

achieve

good

definition

on

the

finished

part?

Material

too

cold

Mould

too

cold.

Insufficientvacuum.

Insufficientvacuum holes in

the

mould

Why

Is

the

plastic

thinning

over

the

mould

when

formed?

Sheet cooled whilstforming.

Mould design

with

insufficient

draft

angles.

Too

thin

plastic gauge.

Pre-stretch required.

Plug assist required.

Why

does

the

plastic

bubble

and

pit

when

heated?

Material

is

Hygroscopic which needs

to

be pre-dried prior

to

forming.

Overheating.

Mould

or

plastic sheet

too

dusty

Why

does

the

plastic

stick

to the

mould

when

Itry

to

release?

Mould

not

fixed on baseboard.

Mould

not

fixed

to

table.

Insufficient

draft

.

Mould undercuts.

Poor mould quality.
