  1. P13651: Final Design

  2. Contents • Revised Design • Subsystem design • Power requirements • BOM/Budget

  3. Hold Wax: Hopper • Designed to hold an entire bag of wax flakes • Reduces operator work during operation • Hopper held within base with springs to reduce affects of vibrations from vibrator For drawings see attached

  4. Transport Wax: Chute • Goal: Transport 2 gallons of wax at a time into the tank • Wax flow controlled by a door operator by a linear actuator • Ideal chute angle to transport wax flakes: 45° • Vibrator is attached to the backside of chute to improve transfer Super-Quiet Low-Impact Electric Vibrator Nonadjustable Force, 115 VAC, 1.4 Amps, 25 lbs Force http://www.mcmaster.com/#catalog/119/517/=lsgnla

  5. Melt Wax: Melting Tank • Goal: Melt 2 gallon batch of wax within 10 minutes • Aluminum tank structure • heaters around exterior wall of tank is sole provider of heat to melt the wax • Aluminum shaft and 2 stirrers induce flow and increase melt rate • Insulation surrounding tank prevent heat loss to surroundings

  6. Heat Requirements • Melted varying quantities of three sample wax in a home wax melting unit • Determined melter efficiency by comparing results from testing to known material, paraffin • Used data to determine amount of energy required to achieve customer requirement of 50 lb/hour

  7. Sample Calculations

  8. System Heaters • System will require 4 heaters to provide enough energy and cover the tank • Heaters will come up to 2.25in down from the top of the tank • Heat density of 100W/in2 Watlow Band/Barrel Heaters http:/www.watlow.com/downloads/en/catalogs/band-barrel.pdf/

  9. Melted Wax Transport • Goal: Achieve 50 lb/hour flowrate • Flow rate out of tank controlled by a door operated by a linear actuator • Outlet through current baseplate into reservoir

  10. BOM: Metal

  11. BOM: Electrical

  12. BOM: Auxilliary

  13. Manufacturing Costs

  14. Budget Breakdown
