Due to the high weight, when it comes to transport and mount, threads are attached on an injection mold in which ring bolts are screwed.
Using the ring bolts, the mold can be easily hung into the indoor crane and mounted on the machine. The threads of the bolts are always designed according to the weight of the mold. Ideally, the location of the ring bolt is at the mold’s center of gravity, that it does not tilt during transportation and installation.
