Nylon vacuum casting

Nylon vacuum casting is a modification of the standard vacuum casting for manufacturing molded parts by the casting of PA 6 in molds made from silicone. The silicone molds are produced in the same way as in the vacuum technology in polyurethane. 

Film preparation All filtered, doped polyaniline salt and blend solutions were solution cast onto a Teflon coated glass substrate. They were covered with a glass dish to allow for slow evaporation (over a period of 24 hours) of the solvent at room temperature. HFIP, with a boiling point of 60 "C, allows gentle stripping at room temperature. All films were peeled off the Teflon tape substrate and (Med in a dynamic vacuum oven at 75 C for approximately 24 hours. From fluorine elemental analysis, percent residual HFIP solvent in films was less than 0.5% (wt/wt). This casting process from HFIP produced robust, free standing and solvent f e polyaniline / nylon blend films. 

Two-component (nylon) polyamide 6 nylon materials are processed in a nylon module and poured into the silicone mold under vacuum. After curing, an accurate impression of the prototype model is developed. Molded parts with undercuts can easily be produced using this method. The casting process is completed after about 2 minutes demolding can be done after about 6 minutes. With this process, molded parts of high quality can be obtained in the shortest time possible and at low cost.
