When evaluating a bolted joint for over-processing, list all of the steps used to The adjustment allows the clamping bolt to be located as close as possible to the mold because that, too, aids in creating maximum clamping pressure on the mold itself. A maximum value allows the mold maker to leave corners sharp as machined with less than a 0. Clamp force is required in order to keep the injection mold closed during the high-pressure injection molding process, which is the primary purpose of the clamp unit. So, a specific machine having a rating of 200 tons is capable of producing a maximum clamping force equivalent to a total of 200 tons. The bolts should be tightened using a torque wrench, with 5/8" bolts requiring approximately 150 ft. A surface finish on both the block and head that falls within the recommended range should provide good cold sealing and long term durability (assuming everything is assembled correctly and the head bolts are torqued in the proper sequence and to the specified torque). I found by myself, just squeezing my brain, some philosophical answers to these questions, but of course I can't technically verify them, so any correction will be very welcome.

MOULD THEORY INDO-ZIMBABWE TRAINING PROGRAMME 2 INTRODUCTION TO PLASTIC MATERIALS Plastics is a unique class of materials, came into existence by the virtue of their superior properties and cost performance balance over to conventional materials like wood, ceramics and metals. A small clamping force may produce defects such as flashes and poor geometrical accuracy, whereas a large force could result in insufficient air venting during mold filling/packing, leading to the generation of short shot. The injection machine is constructed of a mold clamping device that opens and closes the mold tool, and Introducing DME XPress™ Mold Base. The two subsequent injection molding processes are carried out according to the principle of the swivel-platen technique simultaneously in two opposite parts of the same mold. Mold fastenings loosen from many causes: clamping force causes mold compression, the impact and bursting pressures caused by rapid filling of the mold, tensile stresses as the mold is pulled open—all these forces are augmented by inertia and acceleration during fast cycle operation.
