Mould accessories are very important for the use of injection syringe moulds, so we need to regularly inspect the mould accessories during use, which not only helps the use of moulds greatly, but also can pick the service life of jnjection syringe mould accessories.The following are related mould accessories Overhaul skills.


First, cross-check the resistance of the heater. You should have measured the resistance value of the heater when you first started using it, and the end of the year is when it is measured again and compared. If the resistance value has a fluctuation of ±10%, it should consider replacing the heater to ensure that it will not fail at a critical moment in the production process. If the initial resistance value has never been measured, measure it once and use the obtained value as reference data when checking the heater in the future.


Second, check whether there are signs of wear between the guide post and the guide sleeve. Look for signs of scratches or abrasions. This type of injection syringe mould fitting wear is caused by a lack of lubrication. If the marks are just emerging, you can also extend the life of the guide post and guide bush by adding lubricant. If the wear is severe, it should be replaced with new parts. Otherwise, the cavity and core parts may not fit well, resulting in parts with different thicknesses.


Again, remember to remind the operator not to "clean up" the hot tip at the gate. If the operator happens to see a small piece of stainless steel at the nozzle of the mould fitting, it may be a point nozzle assembly. "Cleaning up" this seemingly obstructive thing often destroys the hot mouth. In order not to damage the hot mouth, please confirm the type of mouth of the hot runner system before taking action, and ensure that all operators are well-trained to recognize the different types of mouths they are in contact with.
