CADMOULD SANDWICH is an additional module that allows the simulation of the sandwich injection molding process.

Typical users are injection moulders, tool makers and designers who deal with the manufacturing of sandwich injection moulding parts or sandwich injection molds.
 
This method injects two liquid components into the same cavity in one shot. For this two screws or Einspritzagregate are needed. Injection of the meltsinto the cavity is performed either via one single nozzle or by multiple nozzles at different positions.
 
The minimum requirement for the application of Cadmould Sandwich is Cadmould 3D-F Fill, Pack, FE, and Pre & Post.
FEATURES

• Simulation of the filling and packing phase in sandwich parts
• Calculating in midplane model
• Results (among others): Filling pattern of the individual components, pressure distribution, temperature, flow rates and clamping force
• Wall thickness distribution of individual components
• Determining whether a melt breakthrough of the second component through the first occurs
• Injection profile for both components including simultaneous injection phase
• Simulation of side cavity processpossible
• Internal, user-extensible material database for thermoplastics based on the CAMPUS®-Standard
• Presentation of animated results
• Fast and accurate calculation with temperature and compressible material models
• Very easy to use (Microsoft® Windows® interface)
• Expandable to other Cadmould 3D-F modules

 
ADVANTAGES

• Cost savings by feasibility analysis and reduction of mold modification loops
• Determination of the reasons for unintended melt breakthroughs
• Determination of the reasons why certain areas are not filled with the second component
• Design of process parameters
• Easy presentation of the complex physical behaviour of the two components for internal discussions and professional customer presentations
