With respect to a controller of an injection molding machine, the injection molding machine includes an injection member provided inside a cylinder to heat a molding material and an injection drive source to fill the molding material into a mold device by moving the injection member forward. The controller includes a limiting part that limits a movement of the injection member forward in a pressure-holding process of controlling an injection drive source so that an actual value of a filling pressure acting on the molding material from the injection member becomes a set value, and a determining part that determines an appropriateness of a setting to be used by the limiting part based on information of a sensor provided in the mold device.

A technique for providing assistance in setting the time to increase the clamping force is provided. A control device of an injection molding machine includes a clamping control part and a monitoring part. The clamping control part is configured to change, in a filling step of filling the inside of a mold device with a molding material during clamping, a set value of clamping force from a first set value to a second set value that is larger than the first set value, at a predetermined pressurizing timing in the middle of the filling step. The monitoring part is configured to monitor changes in the actual value of the clamping force due to changes in the set value of the clamping force.

A method for producing multilayer objects from a polymer melt, especially in an injection mold, especially preforms having a barrier layer, wherein a viscosity, especially a shear speed, of the melt is determined. The viscosity, especially the shear speed, of at least one layer is determined in the injection mold and optionally monitored and/or regulated.

A vehicular camera module includes a circuit element and a lens mounting element disposed at the circuit element and optically aligned with an imager of the circuit element. An inner lower pressure polymer molding is formed at least partially over and around the circuit element and the lens mounting element so that the inner molding and the lens mounting element substantially encase the circuit element. A connector element is disposed at an aperture of the inner molding so as to be in electrical contact with the electrical connecting elements of the circuit element. An outer higher pressure injection molded shell is molded over and around the inner molding and part of the lens mounting element so as to encase the inner molding. The outer shell includes a connector portion that generally surrounds the connector element, with the connector element being accessible at the connector portion of the outer shell.

A method and device for injection moulding micro-components, including an injection moulding machine having a mould carrier, which supports a removable mould in which at least one mould cavity is provided; and a counter mould, which is arranged so as to be closed against the mould in such a way as to apply a centering force as well as moulding pressure to the mould when the counter mould is closed against the mould.

A specific mold status Ac is caused in advance in which the interval of an inner portion Xi in the parting plane direction of a parting gap C between a fixed mold 2c and a movable mold 2m during the injection filling is larger than the interval of an outer edge portion Xo and the interval of the outer edge portion Xo is equal to or lower than a predetermined size Ls including 0. A molding injection pressure Pi is set as an injection pressure at which a non-defective product can be molded and a molding mold clamping force Pc is set as a mold clamping force by which a non-defective product can be molded. During the production, a mold 2 is clamped by a molding mold clamping force Pc and the clamped mold 2 is filled with the injected resin R by a molding injection pressure Pi. After a predetermined cooling time Tc has passed, a molded piece G is removed.

Systems and methods for controlling the closing speed of valve gated nozzles are disclosed. In one embodiment, a hot runner have a valve gated nozzle including a valve stem movable between an open position and a closed position is provided. The valve stem is moved at a first speed for a first portion of valve stem closure and a second speed for a second end portion of the valve stem closure.
