Blow Molding

Details

Dalian hollow molding using polymer delayed relaxation time of high elastic deformation temperature dependence, in the vicinity of the above the polymer glass transition temperature TF, the polymer semi-finished products (tubes, hollow profile, etc.) rapid deformation, and then to keep the deformation, in a relatively short period of time is cooled to below the glass transition temperature and the crystallization temperature, deformation of forming frozen down, this is hollow molding of viscoelastic theory. Drawing blowing hollow plastic moulding machine to the pursuit of the goal is to improve the forming speed and its key technology: optimization of heating system in order to reduce the heating time; to improve the transmission speed of operation of the preform; increase preform fast and stable positioning performance; shorten the mold opening and closing and blow molding pressing head lifting time; increase the number of cavity molding.
