Molding presentation

  1. 1. MOLDING MOLDING PROJECTS ENGINEERING Developed by: Helton Luciano Fogaça Weiss Leonardo Semkiw Jr.
  2. 2. Engineering Projects Flowchart Making of the Foundry Project Making of Tooling (pattern + core box) Pattern Storage General Activities - ACVO´s; - Follow-up of Experiments; - Dimensional Evaluation; - FMEA´s; - Development of new Technology. . - Receiving Tooling; - CDM; -Storage; - Sub-contracted pattern shop; ; - Follow-up of Production. - Riser Calculation; - -Gates Calculation; Stock Allowance and Contraction Calculation; -Core Room Projects; -Solidification Simulation.
  3. 3. People in Charge of Engineering Projects Units <ul><li>Felipe Pacheco and John Schultz – </li></ul><ul><li>Under Order Unit and Special Alloys Units </li></ul><ul><li>Fábio Mulhmann – Repetitive Unit </li></ul>
  4. 4. Capacities <ul><li>Elaboration of foundry tooling design for common and special alloys in small,medium and large-scale parts; </li></ul><ul><li>Follow-up of making of tooling; </li></ul><ul><li>Receiving and storing of tooling; </li></ul><ul><li>Maintenace of patterns in use; </li></ul><ul><li>Check list and liberation of tooling for production. </li></ul>
  5. 5. Tools Used <ul><li>Software for designing 2D e 3D; </li></ul>
  6. 6. Solidification simulator software, Solidcast; Tools Used
  7. 7. Molding Flowchart <ul><li>Identifications; </li></ul><ul><li>Element Setting </li></ul><ul><li>. Funnel </li></ul><ul><li>. Gates </li></ul><ul><li>. Sleeves </li></ul><ul><li>. Molds </li></ul>- Filling; - Hardening; - Controls. - Mold ejection; - Painting; - Drying; - Core Setting. Pattern Preparation Extraction/ Preparation Closing/ Clamping Cooling Shakeout Pouring -Core Manufacture -Preparation / Painting Mold Manufacturing
  8. 8. Pattern Preparation In this stage the pattern undergoes a check list to be liberated and receives all the identification the part will contain. Pattern: Upper Half Pattern: Upper Half (Prepared)
  9. 9. Pattern Preparation Pattern: Lower Half Core with structural reinforcement
  10. 10. Molding The elements of the foundry design are put in place: gates, funnel, molds, feeders; The box is filled with a mixture of sand and resin. Filling / Compacting Facing with Cromite Sand
  11. 11. Stripping <ul><li>After the resins are hardened, the extraction of the pattern takes place,leaving the mold ready. </li></ul>Pattern with own frame: Flaskless Mold Pattern plated: Box
  12. 12. Finishing <ul><li>Take away sharp edges; </li></ul><ul><li>Drill the mold ; </li></ul><ul><li>In some cases nylon slugs are used. </li></ul>Drilling Nylon Slugs
  13. 13. Painting <ul><li>Spraying </li></ul><ul><li>Brushing </li></ul><ul><li>Washing </li></ul><ul><li>Immersion </li></ul>
  14. 14. Clamping/Core Setting After drying the paint, the cores are placed;
  15. 15. Taporil Setting and/or Glue <ul><li>The molds are cleaned with compressed air; </li></ul><ul><li>Glue and/or Taporil is placed in order to seal the mold; </li></ul>
  16. 16. Closing Box Closing Flaskless Mold Closing
  17. 17. Clamping After closing the molds are clamped to resist the pressure of leaking . Clamp Clamp and Weight Screw Clamps
  18. 18. PIT
  19. 19. Demolding <ul><ul><li>After pouring and cooling, the part is removed from the mold and the sand goes on for reclamation or is discarded; </li></ul></ul><ul><ul><li>The part makes its way to the Heat Treatment sector. </li></ul></ul>Cold Shakeout
  20. 20. Red-hot Shakeout Demolding
  21. 21. <ul><ul><ul><li>This is an important sector where the cores are made, prepared and painted; </li></ul></ul></ul><ul><ul><ul><li>The cores are also made from a mixture of sand and resin and this gives the form to the part’s cavaties, however complex they might be. </li></ul></ul></ul>Core Room
