<p>Detailed specifications of high-quality injection molding machine</p><p><br></p><p> In order to let everyone know the high-quality<a href="https://www.hisson.com/product" rel="noopener noreferrer" target="_blank"><strong> injection molding machine</strong></a> more effectively, we collected detailed explanations of various specifications of some high-quality injection molding machines.</p><p><br></p><p>1. The injection weight is an important parameter of a high-quality injection molding machine. It is a commonly used parameter for selecting an injection molding machine, expressed in grams and ounces. Although this parameter is simple and clear, it is easy to be misunderstood.</p><p><br></p><p>2. Determine the injection volume. For example, if the injection product is PS material, the injection volume is WPS=(1.3～1.1)*(product weight + total gate system weight).</p><p><br></p><p>3. The relationship between injection weight and volume. The injection weight is not the specific gravity of the injection volume multiplied by the PS. You must know that the injection weight is measured, and the injection volume is theoretical.</p><p><br></p><p>4. To purchase a high-quality injection molding machine with sufficient injection weight, you should not choose an injection molding machine whose injection weight is exactly equal to the weight of the plastic part plus the weight of the runner plastic.</p><p><br></p><p>5. An injection molding machine with a high injection weight cannot be used to avoid errors when the injection molding machine injects small products.</p><p><br></p><p>6. The clamping force of a high-quality injection molding machine is an important parameter in the market, which is the clamping force of the injection molding machine to the mold during processing.</p><p><br></p><p>7. Screw diameter On the injection device, many manufacturers provide a variety of screw diameter models.</p><p><br></p><p>8. The aspect ratio is the ratio of the length of the screw to the length of the screw diameter.</p><p><br></p><p>The semi-automatic operation of the high-quality injection molding machine is by opening the safety door, closing the stroke switch, and sending a signal to start the semi-automatic action of the machine, and then closing the<a href="https://www.hisson.com/pet-preform-mold" rel="noopener noreferrer" target="_blank"><strong> injection mold</strong></a>. After encountering the SQ4 stroke switch, the mold closing ends and the injection starts at the same time. The injection time relay starts timing and the injection time When the time is up, the pre-molding starts, and when it touches the limit switch that has finished pre-molding, it starts to prevent flow. When it touches the anti-flow limit switch, the cooling time relay starts timing. After the time is up, the mold opens, and then the mold opens. After the mold opening terminates the stroke switch, perform the ejection action. After the ejection termination stroke switch is touched, the ejection action is performed. After the ejection termination stroke is encountered, the safety door is waited to open, so that the work is repeated.</p><p><br></p><p>It can be seen from the above that if the manual operation is normal, the general high-quality injection molding machine is mostly caused by the trip switch and time relay not sending a signal. According to which stage of the semi-automatic action fails in the mechanical cycle, compare the electrical appliances and hydraulic schematic diagrams to find out the corresponding control components, and check to solve them.</p>
