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

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

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

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

Purpose and Background Uses in different industries Grips Texturing

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

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

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

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

Process Steps Printing Etching Mold Repair Mechanical Engraving

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

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

Examples Check Parts Circling the Room Various Shapes
