1. Mold Texturizing By: Josh Gropp, Garrett Miller, Andrew Schenck

2. Outline Purpose and Background Advantages and Disadvantages Basic Operation and Process Design Requirements Examples Conclusion

3. Purpose and Background Why use it? Allows part to have natural feel and appearance Leather grain Intricate designs Logo’s Hide surface imperfections Weld lines

4. Purpose and Background What is it used on? Can be used with virtually all ferrous and non- ferrous metals Must be free from inclusions/impurities Must have same properties throughout Should be treated before texturizing

5. Purpose and Background Uses in different industries Grips Texturing

6. Advantages/Disadvantages Advantages Removes necessity for secondary operations Gives parts unique feel/look Increase surface grip Lowers production costs

7. Advantages/Disadvantages Disadvantages Must have hard mold surface (higher cost) Doesn’t work well with reinforced materials Mold surface must be machined/cleaned if EDM is used If done incorrectly parts will not eject or will deform during ejection

8. Basic Operation/Process If texturizing is desired it should be designed into molding process Should be planned for in advance Things like ejectors, draft angles must be accounted for

9. Process Steps Graphic Arts Pattern Master Pattern Transfer Final Masking Vapor Honing

10. Process Steps Printing Etching Mold Repair Mechanical Engraving

11. Design Requirements Draft 1 ½ degrees for each.001 inch Shrinkage of material also determines angle Undercuts Should be considered when designing texture

12. Design Requirements Ribs Hard to texture, so needs to be considered in the design stage Tool surface

13. Examples Check Parts Circling the Room Various Shapes

14. Pricing Based on Complexity of: Mold Surface Texture Material of Mold Time

15. Conclusion Purpose Advantages/Disadvantages Process Design Requirements Cost Things to Remember
