What is the main reason for using a range of wet and dry paper?
To gradually smooth and polish the surface
To color the plastic
To heat the plastic
To make the process longer
What is the purpose of using a metal rule in the process?
To remove marks from filing
To heat the plastic
To color the plastic
To apply wax
What is the correct way to use the wax polishing wheel?
Apply wax to the cloth wheel and polish from the centre towards the corners
Apply wax directly to the plastic
Use the wheel without wax
Polish only the corners
Why is it important to use safety equipment like gloves, apron, and goggles?
To protect yourself from potential hazards during the polishing process
To make the process faster
To make the tools last longer
To color the plastic
What should you be careful not to do when polishing plastic edges?
Snag the cloth on the corners
Apply too much wax
Use a blowtorch on acrylic
Wear protective gloves
How often should you re-apply wax to the wheel to avoid excessive friction?
Every 30 seconds or so
Every 5 minutes
Once at the beginning
Only when the wheel stops
What should you use to remove any remaining wax after polishing?
Polishing mop
Sandpaper
Blowtorch
Water
What finish can you achieve by flame polishing plastic edges?
Really clear glass-like finish
Matte finish
Rough finish
Colored finish
What protective equipment should you wear when flame polishing?
Gloves, apron, and face shield
Safety goggles only
Lab coat and mask
Ear plugs and boots
Which material can only be finished with flame polishing?
Acrylic
High impact polystyrene
Polycarbonate
PVC
What is the main benefit of flame polishing plastic edges?
Quick and simple process with a great finish
Makes the plastic stronger
Reduces the weight of the plastic
Changes the color of the plastic
What is the purpose of using a polishing mop at the end of the process?
To remove any remaining wax
To heat the plastic
To cut the plastic
To color the plastic
What is a key safety step before starting flame polishing?
Put on hot work protective gloves, apron, and a face shield
Turn off all lights
Remove all wax from the area
Use only cold water
Why is it important to avoid snagging the cloth on the corners?
It could damage the cloth or the plastic
It will make the plastic too shiny
It will cause the wax to burn

Which process gives a glass-like finish to plastic edges?
Flame polishing
Sanding
Painting
Drilling

The plastic is changing color
The wheel is spinning too fast
The wax is bubbling
Which material is more likely to melt during polishing due to a lower softening point?
High impact polystyrene
Acrylic
Polycarbonate
Glass
What could happen if you use flame polishing on high impact polystyrene?
It may melt due to its lower softening point
It will become stronger
It will turn blue
It will become transparent
What is the main focus when polishing plastic edges?
Achieving a clear, glass-like finish
Making the plastic heavier
