Thermoplastic powder is placed in the hopper. 2. The heaters doften the plastic which is forced through the die by the archimedean screw. 3. the plastic is cooled as it exits the die. 4. the product is cut to the required length. (9) 4. Tough, flexible, good solvent resistance, good elasticity (6) 5. Ability to withstand impact without fracturing. (9) 7. Hard, brittle, conducts electricity (5) 10. The ductility of a material is a measure of the amount by which it can be drawn out in tension before it fractures, drawn into wire. (9) Down 2. Hardness is the ability to withstand wear, scratching or abrasion. (8) 3. The elasticity of a material is a measure of its ability to withstand elastic deformation. (10) 6. Extremely hard, brittle, tough (8) 8. Tough, flexible, good impact strength, good insulator, low softening temperature, good mouldability (3) 9. the component is heated to above the softening point of the polymer, which is in the form of a fine powder, then dipped into the polymer. The polymer adheres to the heated metal which begins to cool and so the polyer solidifes into a protective layer (7, 7)
