摘要： A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

Gx . . . Gn), wherein one or more recommendations for preferred intervention ranges or manipulated variables for adapting adjustment parameters of the injection-molding machine are associated with ranges (Q Gn) for the values of the quotient Q, e) determining in which of the ranges (Q Gn) the value of the quotient Q lies, and f) outputting the preferred intervention ranges and/or manipulated variables for adapting the machine parameters of the injection-molding machine which are associated with the determined range.

摘要： A monolithic injection molded plastic part including an interior core, a surface formed as a monolithic structure with the interior core, and a distribution of hollow cells formed within the interior core during an injection molding process from a blowing agent and methods for making the same are provided. Such methods include preparing a mixture of unmelted plastic resin, filler agent, and blowing agent, melting the mixture into a viscous combination using a standard injection molding machine, injecting a set amount of the viscous combination into a hollow cavity of an injection mold secured within the standard injection molding machine, and holding the set amount of the viscous combination in the hollow cavity at a low pressure for a hold time until the viscous combination sets into a monolithic structure at least partially filling the hollow cavity and the blowing agent forms a distribution of hollow cells throughout the monolithic structure.

摘要： Provided is an injection molding method in which a constricting section is provided at a boundary between a first stage and a second stage of a screw. When a mixture of a molten resin and reinforcing fibers passes through the constricting section, compression force higher than compression force on an upstream side of the constricting section is applied to the mixture. A supply section on a downstream side of the constricting section has a shaft diameter smaller than an outer diameter of the constricting section. Therefore, the vicinity of the supply section becomes a reduced-pressure region with respect to the mixture having passed through the constricting section, and the mixture is accordingly expanded. As a result, spring-back occurs on the reinforcing fibers and a Barus effect occurs on the molten resin, thereby making it possible to produce a state that is advantageous to open the fiber bundle.

摘要： In an injection molding method of fiber reinforced resin of the present invention, a resin accumulation region is provided closer to a downstream side than an injection completion position inside a heating cylinder, an injection pressure is given to molten resin that occupies the resin accumulation region in an injection process of a preceding cycle, and a shear force is given to the molten resin that occupies the resin accumulation region in a plasticizing process of a subsequent cycle. An inside of massive reinforcing fibers F is impregnated with the molten resin by giving a high injection pressure to the molten resin that occupies the resin accumulation region. Next, dispersion of the reinforcing fibers is promoted by giving a shear force in the plasticizing process of the subsequent cycle.

摘要： In an injection molding method, using a heating cylinder having on the front end thereof a discharge nozzle, a single axis screw is rotatable inside the heating cylinder, a fiber-supplying device fills reinforcing fiber into the heating cylinder, and injection molding is performed while supplying the reinforcing fiber and the resin starting material separately and supplying the reinforcing fiber on the front side of the resin starting material. The method includes a plasticization process for obtaining a specified amount of a kneaded product by retracting the screw while rotating in the normal direction to melt the resin starting material and knead reinforcing fiber into the melted resin starting material, and an injection process for discharging the kneaded product from the discharge nozzle by advancing the screw. Reinforcing fiber is supplied into the heating cylinder in the injection process.

摘要： When the screw moves forward, resin backflow occurs. The backflow acts on the screw, applying torque to the screw. During forward movement of the screw, screw torque is produced as shown in FIG. 3A if the check ring is not worn, or as shown in FIG. 3B if the check ring is worn, because wear increases the backflow and delays the closure of the check ring. The magnitude of the peak screw torque and the associated time and screw position vary depending on the presence or absence of wear, so wear of the check ring is estimated from variations in these physical quantities. The state of wear of the check ring, screw head, check seat, and other parts inside the barrel can be estimated.
摘要翻译：当螺丝向前移动时，会发生树脂回流。回转作用在螺钉上，向螺钉施加扭矩。在螺杆的向前运动期间，产生如图5所示的螺杆扭矩。如图3A所示，如果止回环未磨损，或者如图3所示。 3B，如果检查环磨损，因为磨损会增加回流并延迟止回环的关闭。峰值螺杆扭矩的大小以及相关的时间和螺钉位置根据磨损的存在或不存在而变化，因此根据这些物理量的变化估计检查环的磨损。检查环，螺丝头，检查座和桶内其他部位的磨损状态可以估计。
