1. MOLDING MOLDING PROJECTS ENGINEERING Developed by: Helton Luciano Fogaça Weiss Leonardo Semkiw Jr.

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.

6. Solidification simulator software, Solidcast; Tools Used

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. Pattern Preparation Pattern: Lower Half Core with structural reinforcement

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

14. Clamping/Core Setting After drying the paint, the cores are placed;

16. Closing Box Closing Flaskless Mold Closing

17. Clamping After closing the molds are clamped to resist the pressure of leaking . Clamp Clamp and Weight Screw Clamps
