7. CW Thomas What is Thermoforming? Thermoforming is a broad based term that means to Stretch a Flat sheet of Plastic using Heat, vacuum and air pressure into a 3 dimensional Shape using a mold. It can basically be divided into 3 categories: Vacuum Forming, Pressure Forming and Twin Sheet. 7

9. Tooling – The Heart of your Part Of the many things required for a successful Thermoformed Part perhaps the most important is the Design of the Tooling. Properly design molds and trim fixtures made from the correct choice of materials will transfer into consistent quality finished part for the life of your program. 9

11. Thermoforming vs. Injection Molding Both processes are viable to manufacture 3D polymer parts. How do we help the customer decide which process is best for their next project? 11

12. Process Overview 12 ThermoformingInjection Molding Tooling A single sided 3D form is created out of aluminum A double-sided 3D mold is created out of steel, aluminum or a beryllium-copper alloy Materials Flat sheets of thermoplastic, available in a variety of materials, finishes, colors, and thickness Thermoplastic pellets, available in a wide variety of materials and colors Production A flat sheet of plastic is heated then molded to the tool’s shape using either suction from a vacuum, or both suction and pressure The plastic pellets are heated to a liquid state and then injected into the mold Finishing The final pieces are trimmed robotically, then can be used uncoated, painted or have specialty coatings The final pieces are removed from the mold, then often need to be painted and be silk- screened or have specialty coatings

13. Other Considerations ThermoformingInjection Molding Tooling Costs $$$$$$$ Per-Piece Production Costs $$$$ 13 Creating a single sided thermoforming tool is much cheaper than creating a double sided mold to be used in injection molding. However, the cost of each individual part is generally cheaper with injection molding.

16. Other Considerations ThermoformingInjection Molding How does it look unpainted?ExcellentHighly Variable Does it allow variable thickness within a single part? LimitedYes How large a part can it reasonably produce?5’ x 9’4’ x 4’ (on standard equipment) 16

17. Guidelines to choose the appropriate process Thermoforming 1. Part Size Creating large parts up to 5’ x 9’, and consolidation multiple parts into a single large part 2. Run Size Creating small to medium (100 – 3,000) runs of parts 3. Aesthetics Aesthetically pleasing unpainted part Injection Molding 1. Part Size Creating small parts with minimal consolidation 2. Run Size Creating large runs (3,000+) of small to medium- sized parts 3. Variation Creating parts with variable thickness in a single part 17

18. CW Thomas Process & Capabilities Pressure Forming Pressure forming provides parts that are visually identical to injection molded parts at a fraction of the tooling cost. Vacuum Forming Vacuum forming produces a one-sided part whereby the sheet color and texture provide finished part aesthetics. Large Part Vacuum Forming Reduce the number of overall components by combining multiple parts within a 5’ x 9’ sheet size.
