Abstract: Provided is a method for manufacturing a protection board. A reinforcement fabric including multiple reinforcement fibers is provided, each reinforcement fiber containing multiple adjacent filaments, each filament being composed of a core and a shell formed around the core, and a melting temperature of the shell is lower than a melting temperature of the core, the shell of each filament attached to the shell of the adjacent filament. The impact strength of the shell is higher than the impact strength of the core. The reinforcement fabric can be manufactured into a protection board with good impact resistance simply through heating and molding. Therefore, the reinforcement fabric has the advantage of both manufacturing a protection board with good impact resistance and reducing its process complexity and cost.

Abstract: A system and method for forming plastic sheet into a three-dimensional shape. The plastic sheet may include one or more sheet-mounted components, such as electronics, that must be shielded from excessive heat, pressure, and/or crushing when the formation of the sheet occurs. A recess will be formed to protect against directly contacting sheet-mounted component. The recess may be aligned along the heating plate and/or the form core and/or along a protective blanket which may be set over (and under) sheet prior to heating/forming. The sheet is registered (with or without a blanket) onto a base plate, and preferably over a form core. The sheet is then raised to contact with a heating plate, and then placed downward over the (optionally heated) form core. Recess(es) align in locations corresponding to mounted component to protect same.

Abstract: A rubber distributor for injection molds wherein the distributor comprises two or more modular units, sleeves each interchangeably insertable in a modular unit, one or more injectors to feed melted rubber to the distributor and one or more discharge nozzles to discharge the melted rubber from the distributor towards an external mold. Each sleeve has a through hole extending along the longitudinal axis of the same sleeve. Sleeves have a groove extending over respective side surfaces. Groove and the inner surface of the respective housing in the modular unit define a coil that can be supplied with a thermoregulating fluid whenever the sleeve is inserted into a modular unit. The modular units can be constrained to one another to define one or more channels for distribution of melted rubber that extend from an injector to one or more discharge nozzles, depending on a desired path. Modularity of the units allows the distributor to have ducts for distribution of melted rubber of a desired geometry.

Abstract: An injection molding heat removal sensing and control system and method are provided for determining and controlling a heat transfer rate for a mold in a molding machine. The system includes an inflow temperature sensor for sensing an inflow temperature for coolant provided to the mold, an outflow temperature sensor for sensing an outflow temperature for coolant exiting the mold, and a flow rate sensor for sensing a flow rate for coolant through the mold. The electronic processor is also configured to calculate a heat transfer rate for the mold from the inflow temperature, the outflow temperature, the flow rate for the coolant, and the calculated mass and the temperature of the molten plastic. The processor determines a time lag between when heat enters the mold and when heat is removed by the coolant and pre-emptively adjusts coolant flow rate to provide uniform heat transfer throughout a molding cycle. The heat transfer rate and total energy removed can be determined and provided on the display.

Abstract: When an injection molding machine performs molding, the mold clamping force on the mold is adjusted on the basis of a mold displacement of the mold or the injection peak pressure and injection foremost position so that the molding is performed without causing flash and by an appropriate mold clamping force with which energy can be reduced. The amount of mold displacement and also the injection peak pressure and the injection foremost position are monitored during automatic operation. If there occurs no mold displacement change exceeding a threshold or if there occurs no injection peak pressure anomaly or injection foremost position anomaly exceeding thresholds, the automatic operation is continued. If the mold displacement change occurs or if the injection peak pressure anomaly and the injection foremost position anomaly occur, the operation of the injection molding machine is stopped.
