To
Process Acrylic Products |
 |
 |
| |
| Some
points might to be noticed
during processing, acrylic
products. |
| |
| 1. |
CUTTING
: |
|
Acrylic
products could be
cut easily on saw
sable by tungsten
saw blade. However,
beamare that in the
process of cutting
heal would be generated
by friction which
could result cutting
surface becoming inferiority.
Below list is showing
some status should
be noticed during
the process. |
|
|
 |
|
 |
 |
| |
 |
 |
| REMARK
:
|
Above
information is only
for reference, doer
should apply various
machine characteristic
to find out better
effect |
|
|
|
| |
|
| |
| 2. |
To
form by heating : |
|
| A. |
Acrylic
tube & rod can be softened
after heating and easily
to bend or form to different
shape. |
| B. |
Apply
hot wind blowing type oven
equipped with thermometer
controller to heat products.
|
| C. |
Before laying products on
the plate to heat in the
oven, one piece of cotton
cloth should be used to
cover the place or use silicon
sheet as plate.
This will avoid the surface
of acrylic productsto be
damaged or scraped. |
| D. |
Do not crowd or pile up
acrylic tubes or rods together
to avoid products could
be adhered during heating. |
| E. |
To
have good result fcr processing,
the temperature of healing
should be kept around from
130°-150°C. |
| F. |
Once
acrylic product is exposed
in humid areatoo long lime
and need for re-heating.
Temperature for re-healing
should be from 80°-90°C
and last for 2- 3 hours.
Without re-heating to get
rid of humidity, your products
will generate bubbles. |
| G. |
Product
after healing will result
some shrinkage. We control
our product wilhin 3% shrinkage.
Therefore, before heating
you must arrange some extra
length. |
| H. |
Wood,
aluminum, brass and silicon
can be used to make mould
for forming product shape,
However, surface of mould
must be polished smoothly
to avoid acrylic product
scraping. |
|
|
|
|
| |
|
|
 |
| 3. |
Surface
polishing : |
|
| A. |
Extruded
acrylic product
itself is bright,
no polishing
is required. |
| B. |
Cutting
face of acrylic
product can
be polished
by wheeled-cloth. |
| C. |
To flame the
cutting face
also will result
shining surface.
|
|
|
| |
| 4. |
Adhesion
: |
|
| A. |
Surface
for adhesion
must be cleaned
before adhering. |
| B. |
Use
(CHCl 3) as
bonding agent
or instant adhesive
agent or suggestion
from bonding
agent factory, |
|
|
| |
| 5. |
Drilling
: |
|
| A. |
| Selection
of drill |
|
| Point
angle
|
60°
- 90°
are suitable, |
| Lip
relief
angle |
12°
-15°
|
| Helix
angle |
10°
- 20° |
|
| B. |
Drilling
speed:
The speed to
drill 10Ø
diameter rod
is 800 rpm.
Smaller drill
can drill faster.
Otherwise the
speed has to
slow down. |
| C. |
Attention points
:
| 1. |
Friction
would
generate
heat in
the process
of drilling
and causes
drilling
hole undesirable,
in this
case use
low dissolve
soap water
as drilling
agent
or high
pressure
cold air
to decrease
the friction
heat. |
| 2. |
Drilling
bits must
be expelled,
otherwise
bits would
affect
the surface
of drilled
product.
|
| 3. |
Hole
should
be drilled
grandually
and many
times.
Avoid
to drill
only one
time to
get through
to the
bottem. |
| 4. |
Drill
must be
inspected
to make
sure it
is sharp
before
using.
Make sure
point
angle,
lip angle
as well
as helix
angle
are at
proper
positiun.. |
|
| D. |
To drill a good
hole besides
paying attention
to the above
few points,
driller could
always make
proper adjustment.
So drilling
is no more a
difficult task. |
