1. EVA Magician for Injection Molding of EVA Shoe Soles

2. EVA Magician Introduction EVA Magician is a powerful customized system specially for EVA injection mold. It automatically calculates the ratios based on the thickness of each section, scales and smoothes 3D models.

3. EVA Magician Product Features Quickly scales original models Based on material characteristics, fits scaled curves using scaling ratios Has various cross-section cutting and calculating methods suitable for material and model characteristics Provides editing functions able to meet design requirement

4. EVA Magician Traditional Procedure Disadvantages: Time-consuming Complex Complicated revisions required Inter-departmental communication needed which may be difficult Standard 2D engineering drawing Measure product Correct Check result Incorrect Revise Standard 3D CAD model Calculate expansion ratio Redraw scaled 2D engineering drawing Create scaled 3D CAD model

5. EVA Magician Innovative Procedure Advantages: Complete procedure, combines automatic ratio calculation and fixing shapes to accomplish scaling requirements Scaling finished within one day Special editing functions simplifies revisions Standard 2D engineering drawing Standard 3D CAD model Check result Correct Measure product Incorrect Revise EVA Magician

6. Efficiency Shortens the time in scaling 1 WEEK1 DAY Simplify the scaling procedures Complete in EVA Magician Easy editing process Specialized editing function for scaling model

7. EVA Magician Quickly Scaling Original 3D CAD model Scaled 3D CAD model Scaled cross- sections automatically generated. Scaling ratios for cross-sections automatically calculated based on material characteristics.

8. EVA Magician Functions Table of scaling ratios management for various EVA materials Quick scaling of 3D models Quick scaling of 2D drawings Editing Functions

9. EVA Magician Ratio Table Management Manages ratio tables for various EVA materials Scaling ratios can be revised

10. EVA Magician Scaling Ratio Calculation Automatically calculates scaling ratio and fits scaled curves Reduces calculation errors done manually

11. EVA Magician Quick Scaling 3D Model 3 Simple steps required for scaling 3D models: - - Sections Setup -- Thickness Calculation -- Scaling

12. EVA Magician Cross-sections: Automatic Two ways of automatically creating cross-sections Start from the center Start from the heel

13. EVA Magician Cross-sections: Manual Set up cross-sections manually-- location,add, delete. No limit to the number of cross-sections ADD Delete

14. EVA Magician Thickness Calculation Horizontal or vertical calculation methods Cross-sections automatically smoothed while proceed scaling

15. EVA Magician Cross-section Scaling Various methods for cutting cross-sections -- Select appropriate sectioning mode -- Improve scaling precision Two sections One section Thickness of 2 sections Average thickness of 2 section Four sections

16. EVA Magician 3D Surface (IGES) Scaling Before Scaling After Scaling

17. EVA Magician 3D Mesh Model(STL) Scaling Before Grading After Grading

18. EVA Magician Scaling 2D Drawing 2D drawing matches result of 3D scaling 2D drawing updated after 3D scaled model is edited

19. EVA Magician Cross-section Editing Basic editing functions Maintain shapes Adjust for concavities Editing Strengthen Adjust cross-section sizes Length revision 3D mould retrieving

20. EVA Magician Maintain Shapes For expansion at local areas, set local scaling ratios. Fix and keep thickness locally Fix and keep height locally Blue ： Original cross-section Pink ： Scaled cross-section Red ： After adjustment

21. EVA Magician Concavity Compensation Blue ： Original cross-section Pink ： Scaled cross-section Red ： After adjustment Set angle and distance to adjust for concavities and to compensate for expansion.

22. EVA Magician Editing Strengthen Angle of the sidewall can be adjusted -- Avoid the sidewall bending toward to inward or outward after scaling Blue ： Original cross-section Pink ： Scaled cross-section Red ： After adjustment

23. EVA Magician Size Adjustments Adjust sizes of major cross-sections, such as Top gauge Width of sole Height at waist etc. Blue ： Original cross-section Pink ： Scaled cross-section Red ： After adjustment

24. EVA Magician Length Revision (I) Set the scaling ratio for an area to revise length

25. EVA Magician Length Revision (II) Directly revise Y value of cross-section Length adjust on a scaled model By moving the y value of a cross- section on the scaled model to get a requested length of a model

26. EVA Magician 3D Model Retrieving From scaled model to retrieve the original model with the same scaling ratio Shortens revision time Original 1 ： 1 ModelRecalculate 1 ： 1 Model
