📚 Revision Notes
Working with Plastics
Definitions
- Plastics: Materials made by humans using long molecule chains. They can be moulded when soft and become hard or flexible after.
infoNote
Note: Plastics are versatile due to their ability to be moulded and set in various forms.
Fundamental Techniques for Working with Plastics
- Cutting:
- Use saws like tenon or hack; make sure to hold the plastic firmly.
- Keep the saw level to avoid shaking and breakage.
- Use rotary cutters or scoring tools for exact cuts.
- Make edges smooth with sandpaper to avoid injury.
infoNote
Note: Ensuring a stable and smooth cut is essential for safety and result quality.
- Shaping:
- Use heat guns to bend the plastic.
- Apply heat slowly to prevent cracking.
chatImportant
Important: Avoid overheating plastics to prevent cracks and ensure shape integrity.
- Assembly:
- Use glue that works with plastics.
- Clean surfaces well before sticking them together.
Health and Safety Practices
- Major Practices:
- Wear gloves and safety glasses.
- Use masks to avoid breathing in dust.
- Tie hair back and secure loose clothes.
- Keep the area clean to avoid falling.
- Common Hazards:
- Watch out for sharp edges and fumes.
- Be careful with tools to avoid cuts.
chatImportant
