摘要： An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; a pressure sensor that is provided in the clamp, wherein the pressure sensor measures contact pressure that acts between the moving plate or the fixed plate and the clamp; and a controller for performing a measure to prevent detachment of the moving plate or the fixed plate based on the contact pressure.

摘要： An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; and a controller that controls separation force that acts on the moving plate or the fixed plate such that the separation force is less than the attractive force.

摘要： A performance in a technique using a heater for manufacturing a resin molding product is further improved. A method of manufacturing a resin molding product includes: a step of placing a first portion configuring a resin molding product, in a first mold; a step of placing a second portion configuring a resin molding product, in a second mold; a step of inserting a heater between the first mold and the second mold; a step of partially heating the first portion and the second portion by the heater; a step of evacuating the heater; a step of welding the first portion and the second portion; and a step of extracting the resin molding product including the first portion and the second portion.
