1, get together cyanogen ester foaming plastics or polystyrene foamed plastic the nc machining out a Lord of the model type, type surface size 10-15 mm to enlarge the machining allowance as a model. Will model the manual work with paste resin mixed evenly, the shop is stuck in trans, thickness in 20-30 mm is advisable.
2, put the glass fiber cloth with resin (M/Y956) invasion, the shop is stuck on the back pressure really model paste 2-3 layer: will be prepared skeleton fixed in the back of the glass cloth, solder place with epoxy mastic fixation; The requirements of framework: it should meet model in processing, when using the strength, stiffness and size stability; The specific structure of the model to determine the size and shape, generally includes the underside structure (including benchmark) + support structure + type surface structure. (note: skeleton to do annealing processing)
3, room temperature immobilized 24 hours after, get rid of the foam plastic, and then the numerical control processing; Because the paste is mixed by manual model, after processing type surface will inevitably appear pinhole or sand holes, need repairing adhesive sealing to fill sanding processing.
