The base plate on which the hot chamber is housed and the die plate are both made of a weak steel (C40), which is not ideal for containing the stresses exerted during the injection phase. <\/p>\n\n<p class=\"wp-block-paragraph\">In our opinion, there is a fundamental problem with this system, which is over a meter long. During the injection phase, the chamber flexes (lung) because the barrels between the base plate and the die plate are not fixed to both plates but only to the back plate. It is not a rigid structure; it deforms, misaligning the nozzles and causing leaks.<\/p>\n\n<p class=\"wp-block-paragraph\">The presence of laminations and thicknesses to compensate for deformations does not solve the problem, but rather worsens it because when the system flexes, the forces exerted instead of being distributed are concentrated in the nozzles that have in fact cracked.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Our proposal:<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\"><strong>New material:<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Nozzle bodies, nozzle resistors, nozzle thermocouples, chamber resistors, chamber thermocouples, inlet sealing ring, electrical cable, sheaths, electrical connectors<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Modifications and workmanship:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Removal of broken screws and plugs from the chamber and provision of screws with stops to keep the resistors in place<\/li>\n\n\n\n<li>Grinding the chamber to restore contact surfaces<\/li>\n\n\n\n<li>Grind the barrels and arrange threads on both sides so that they can be screwed to both plates<\/li>\n\n\n\n<li>Replace existing screws with enlarged screws and class 12.9<\/li>\n\n\n\n<li>Lardoni grinding to compensate for hot chamber grinding<\/li>\n\n\n\n<li>Modify the die plate to provide threaded holes to screw the barrels<\/li>\n\n\n\n<li>Laser welding and machining cracked nozzle seats in the die plate<\/li>\n\n\n\n<li>Processing of the base plate and insertion of interchangeable hardened steel pads to be inserted under the barrels to correct the deformation of the plate and restore the original dimensions<\/li>\n\n\n\n<li>Replacement of nozzle centering inserts in the matrix<\/li>\n\n\n\n<li>Final assembly with closure control<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Observations:<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">This project has allowed a mold of over 20 years to resume production efficiently with a low investment and quick times.
