The determination of the main parameters of the plastic extruded mold is still in the experimental stage, so the test mode is an important tool for the inspection of the mould.
Successful extrusion moulds must be able to produce products that meet the requirements.
To meet the material characteristics of the products and ensure the strength of the products;The mould should be able to be installed on the equipment and work at a given speed, so as to obtain reasonable control of molding process conditions and adapt to the technical specifications of the extruder.However, the extrusion moulds are generally not ideal when they are first tested.The test model will reflect various defects, which can be summarized as the following four aspects:
(1) the extrusion molding mould caused by material properties is not adaptable;
(2) unreasonable technical specifications of extruders and auxiliaries;
(3) the molding process conditions cannot meet the requirements;
(4) extrusion mold design or manufacturing problems.
