Circle the appropriate answer, “T” for true or "F" for false 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Thermosets are materials utilized to cast usable parts in conjunction with RTV molding If material is in a liquid state, the process is called "Casting”. When using a barrier coat, it should be applied prior to casting. Shore "A" is used to measure the hardness of Plastic. All silicone is mixed at a ratio of 100 to 10. Gas cans are typically manufactured using polystyrene materials. Sulfur based clays are prone to inhibition. Blow molding is a process for forming solid industrial parts. Demold time is when a thermoset material can be removed from the mold. The mixing ratio for two part resins are typically by weight. Forming utilizes a shaping device with pressure to cause material to take on new shape and size. Tin Cure silicone is sensitive to inhibition. Plastic that is extruded from height between to mold halves and has air blown into it is the process of “injection molding”. Shore "D" is used to measure the hardness of Rubber. Thermoforming is a relatively new process and never utilizes automation in the process. Elastomers can be melted or dissolved. Viscosity indicates how well a material flows. HIPS is another name for high density polyethylene. Tin Cured Silicone's curing time can be accelerated by heat. Thermosets cure time can range from a few minutes to several hours. 12. 13. 14. 15. 16. 17. 18. 19. 20.
