Things Needed
Thermoplastic is a polymer charge card that becomes flexile when ignite and substantial when cooled . usual plastics such as Acrylic are thermoplastic resin . Because thermoplastic such as Acrylic can crack when being cut , care must be take when crop with this type of fabric . Plastics retailers can cut plastic to size but there is often a cutting accusation associated with this service . Use a few coarse shop creature to cut thermoplastic resin yourself .
Step 1
alter the proverb ’s blade . Thermoplastics require a sharp 80 - tooth carbide tipped leaf blade . Remove the steel cover . take out the sometime steel and interchange it with the carbide - tip blade , following the saw manufacturing business ’s instructions for blade transposition . Use a new blade for cutting thermoplastic resin .
Step 2
Step 3
Adjust the blade pinnacle . Most plastics are slender . Thin charge plate are flexible so the blade height must be conform to compensate for this . mark the blade height at three times the thickness of the charge card being cut . If the plastic is ¼-inch thick , the blade height will be 3/4 - inch .
Step 4
Turn the saw on . It is important to countenance the saw to run for at least two minutes before cut the credit card . If the adage is not running at full speeding , the plastic could melt as it is pushed through the blade .
Step 5
sic the blade ’s length from the fence . distinctive carbide - tipped proverb blades remove 1/8 - column inch of plastic when they curve through the cloth . Set the sword ’s aloofness from the fence by measuring the distance from inside edge of one of the carbide tips to the fencing . advertize down on the fencing clinch to tighten the fence into position .
Step 6
set the charge plate against the fence . bear on the lead border of the credit card being curve against the face of the fence so at least 6 in of plastic rests evenly against the fence .
Step 7
Cut the plastic . Thermoplastics have lower melting points than other materials . The rate at which the charge plate should be prey through the saw is 3 to 4 inch per second . This prevents melting and chip .
Tip
For cutting out small snick and angles , use a saber saw . Purchase a fine tooth blade with 10 to 13 teeth per in .
