Sliding friction of thermoplastic slip in the casting process

Use of ultrasound in order to intensify molding of high-temperature thermocouple sheaths

“…the height of the cold zone). Thereby the possibility is opened up of a marked (by a factor of 2 -3) increase in the maximum permissible casting rate, that is specific factor of the production process [3].…”

“…Considering the pressure loss, connected with viscous flow of unsolidified slip, that is insignificant compared with forces required for overcoming friction in the cold zone [3], the condition of equilibrium forces with movement of solid slip in the cold zone of the die, i.e. when pressure in the slip equals the sliding friction force of solid slip over the walls of the die, may be expressed by an approximation equation 3…”
