Abstract: A molding cycle stopping method includes: in a case of stopping an operation of a molding cycle in an injection device including a heating cylinder and a screw provided in the heating cylinder, performing a temperature lowering process including lowering a temperature of the heating cylinder from a molding cycle execution temperature to a standby temperature; and performing a continuous purge process including repeatedly purging a resin until a predetermined termination condition is satisfied.

Abstract: An injection molding machine includes a control device configured to output at least one set of operator support information. The operator support information includes a set of support target setting data and control target predicted amount of power. The support target setting data includes at least one piece of setting data configuring a molding condition. The control target predicted amount of power is a predicted amount of power consumption of a control target controlled in association with the support target setting data with respect to a change in the support target setting data.

Abstract: A heating cylinder heater includes a plurality of infrared heaters disposed around a heating cylinder in a non-contact manner with respect to the heating cylinder, a heat insulating material provided outside the infrared heaters, and a cover configured to cover the heat insulating material. The cover has two or more opening portions, and a part or all of the two or more opening portions are each provided with an opening-closing device that is configured to open and close the corresponding opening portion.
