INTRUSION IN INJECTION MOLDING


Intrusion


 If the intrusion time is set greater than zero, then the screw will be rotated during this time immediately prior to injection. Material will thus be introduced into the mould.  
 
Both pressure and screw rotation speed can be set separately. 


Cold Slug Removal

 If it is necessary to remove the cold slug from the nozzle before injection, the appropriate selection can be made from the program options together with a time when the slug is to be removed by injection.  


Both injection pressure and speed can be set separately.  
 
This operation occurs before injection unit moves forward.

TROUBLESHOOTING FLASH IN INJECTION MOLDING MACHINE

FLASH IN INJECTION MOLDING PRODUCT Flash is Nothing but just an extra material over the molded product , Flash causes loss of material at the time of molding and sometimes it also destroys the surface beauty of the product . MAJOR CAUSES OF FLASH 1. Material Too Hot at the time of injection and in the mold. 2. Injection pressure is too high. 3. Excessive Feeding of the material in the mold. 4. Improper or Uneven feeding of the material. 5. Poor parting line or the mating surfaces of the mold. 6. Mold deficiency means problem in the mold manufacturing. 7. Injection Pressure is higher than Clamping pressure. 8. Erratic or uneven or improper cycle time. TROUBLE SHOOTING THE FLASH TEMPERATURE :   Check the cylinder temperature that means check the temperature of your barrel make it low if it is higher. Reduce the temperature  of the nozzle that is an important aspect. Reduce the mold temperature if it is higher. MOLDING SETTINGS : Increase the clamping force to make proper cl...

COMPLETE PROCESS PAGE OF INJECTION MOLDING MACHINE -1

Image
This page comprises of the most important process parameter. Cycle time Set  The set cycle time acts as a monitoring time for the completion of cycle. If, due to some reason, the cycle fails to complete within the set time, the machine will signal an alarm.  Actual: The time taken by the machine to complete one cycle. The set cycle time should be higher than the actual cycle time.          Cycle time - last shot                     #   The time taken by the machine to complete the previous shot. Useful for checking the effect of a change in the process parameter.         Blocking time                 #  Blocking time starts after the set cycle time expires. At the end of blocking time the machine goes into shut-off mode as per the switch off matrix setting.         Pa...

TROUBLESHOOTING WELD LINES / FLOW MARKS IN INJECTION MOLDING

 WELD LINES AND FLOW MARKS MAJOR CAUSES FOR THE DEFECT : Molten plastic material is too cold in the mold after injection. when there is an excessive mold lubricant in the mold. Mold is too cold . Injection speed is slow. Low injection pressure. Volatile gas are been trapped in the mold. Air unable to escape from the mold as fast as it should.           TROUBLE SHOOTING : Increase injection pressure. Increase injection speed. Increase plasticizing capacity of machine if possible. TEMPERATURE : Increase Barrel / Cylinder temperature. Increase Nozzle temperature. Increase Mold Temperature. Make proper/even/balanced cooling system for the mold. MOLD : Add proper vent on the mold. Increase the runner system in the feed channel. Increase the gate system. Increase the opening of sprue. Make necessary adjustment for the mold adjustment. Thick the particular area where the welded part is too thin. Filling rate of the material in the mold should be equal. Incre...
