The products produced by injection molding machines include flying edge, burn and burn
As for what you are talking about, guess you've just learned how to adjust the machine. These problems can only be produced in the new test die, and the mold will be carbonized because of the foreign matter in the cavity...... There is a problem in communication, to rest.
Hello, my friend! These three problems are unlikely to appear on the same product. Because you ask the question is more general, have to obscure answer, for reference only. 1, flying edge: with higher sol temperature, low mold pressure, the mold itself is related to the problem. 2, burns and burns are generally caused by poor exhaust problems, you can adjust the injection speed, adjust the clamping force, improve the exhaust situation to solve. May ask again. Please make the question more specific and easy to answer. For reference only.
2, manual operation, parameter correctionThe locking mold (confirm pressure rise), ejection seat.In the manual injection screw until completely stopped, and pay attention to the stop position.The screw feed back.The mold molding removed after cooling.The 1 ~ 4 repeat steps, the final stop in 10%~20% screw diameter screw position, and no molding short shot, flash and whitening, or cracking phenomenon.
Injection molding machine debugging process is generally divided into three steps:1 、 before setting the parameters, confirm and prepare the parametersTo confirm the material drying, mold temperature and temperature of the heating cylinder is correctly set and achieve processing state.Check the die opening and closing and push out the movement and distance setting.The injection pressure (P1) set at the maximum value of 60%.Keep the pressure (PH) set at the maximum value of 30%.The injection speed (V1) set at the maximum value of 40%.No screw speed (VS) is set at about 60RPM.Back pressure (PB), set at about 10kg/cm2.Very loose denunciation set in 3mm.Only the pressure switch in position setting screw diameter 30%. For example, the screw of phi 100mm is set 30mm.We will travel slightly shorter than the calculated value measurement set.His total injection time is short, the cooling time is slightly longer set.
