Prototyping When time to market is critical, customers contact Lupton Associates. Depending on the process selected, one part or several thousand can be produced prior to the release of production capital. Whether the purpose is to verify the design or to provide pre-production quantities, we can select the appropriate process and materials to get you to market as quickly as possible. Processes utilized include: Stereolithography, RPM, LOM Cast Urethanes Plaster Mold Castings Graphite Casting (aluminum or zinc) Air Set Sand Castings (aluminum or zinc) Metal fabrication Metal stamping Thermoforming and Vacuum Forming Injection Molding Reaction Injection Molding Thixomolding CNC Machining and Turning Plastic Fabrication Extrusions (polymeric and aluminum) PC Board and Box Build assembly request a quote Copyright © 2018 Lupton Associates

Thermoforming Thermoforming or Vacuum Forming, uses an extruded sheet of thermoplastic. The sheets are individually heated to make them malleable. They are then drawn over a mold half to replicate the surface of the mold. Unlike injection molded parts, thermoformed components have molded in details on only one side of the component. Bosses and ribs are typically added as a part of a secondary bonding operation. A vacuum is used to pull the sheet tightly into the contours of the surface and evacuate any trapped air. This allows for details to be captured on the part that will closely replicate that of injection molding. Once the molding cycle is complete, air is blown across the surface of the part to cool it until it has hardened sufficiently to be handled. Typical applications for Thermoforming are enclosures, bezels, returnable packaging, seating, control panels and exterior parts for tractors and other lower volume vehicles. Thermoforming characteristics include: Ability to produce a part which is medium to large in size A high level of complexity on one side of the molding Tooling cost is much lower in comparison to Injection Molding Quantity is relatively low < 10,000 download our design guide Copyright © 2018 Lupton Associates
