The present invention discloses an injection molding control method. The injection molding control method comprises the following steps: establishing a work command according to a plurality of production process parameters; receiving a position information directly from an injection molding machine; and controlling a servo pump to drive the injection molding machine according to the position information and the work command.

An injection assembly, for pressure die casting systems, has an injection cylinder adapted to inject liquid metal into a casting cavity; the injection cylinder is actuated by a hydraulic flow of an oil-pressure controlled circuit; the oil-pressure controlled circuit includes a hydraulic cushion which blocks and releases the flow of the hydraulic fluid in the injection cylinder and provides a counter-pressure of preset value to control the injection speeds and to prevent cavitation in the injection cylinder.

A remote controller can be provided on any apparatus that employs feedback control from a native controller to add functionality to the apparatus where the native controller is not capable of providing such functionality independently.

An apparatus for injecting a molten plastic material into a mold is described. The apparatus includes a heated manifold (manifold) with channels to distribute molten material inside it, and a heated injector, to inject molten material to the mold cavity, equipped with a translatable shutter to regulate the flow of the injected molten material.

An actuator is attached to the manifold to receive molten material from it to send to the injector and move the shutter. The actuator includes a piston connected to the plug, and a first conduit to bring a pressurized fluid from the outside to the piston. A plate includes a second internal conduit to bring pressurized fluid to the injector, where a gap separates the plate and the actuator.

A connecting member is mounted to cross the gap and carry pressurized fluid from the plate to the actuator.

An arrangement with a first clamping unit including a first fixed platen and a first movable platen movable relative thereto, a first clamping force mechanism to apply a clamping force to the first movable platen, and a control or regulating unit for controlling or regulating the first clamping force mechanism. Arranged next to and/or above the first clamping unit is a second clamping unit including a second fixed platen or the first fixed platen and a second movable platen movable relative thereto and which are suitable for carrying at least one mold, and a second clamping force mechanism to apply a clamping force to the second movable platen. The control or regulating unit can actuate the first clamping force mechanism and the second clamping force mechanism to apply a clamping force synchronously when all platens present jointly carry a mold.
