Kunshan Xuanrun Precision Machinery Co., Ltd. specializes in the production and sales of mold accessories. Regular maintenance of mold accessories plays a crucial role in the service life of molds. The annual maintenance program required for each injection molding position depends on different mold cycle times. What are the best ways to repair mold parts? Here are some experiences and methods of Kunshan Xuanrun Precision Machinery for repairing mold parts:
1、 Check for any warning signs of rust or moisture at the air vents. If you find rust or moisture near the hot runner exhaust hole, it means internal condensation or the possibility of water pipe rupture. Moisture can cause a fatal short circuit to the heater. If the machine does not run continuously throughout the year and needs to be shut down at night or on weekends, then the probability of this condensation phenomenon occurring is
2、 Check for signs of wear on the guide post and guide sleeve. Search for any scratches or abrasions, as the wear of these mold components is caused by a lack of lubrication. If the traces are just beginning to appear, you can also extend their lifespan by adding lubricant to the guide post and guide sleeve. If the wear is already severe, then it is time to replace the parts with new ones. Otherwise, the cavity and core parts may not fit well, resulting in uneven thickness of the component cavity wall.
3、 Attach a prominent sign to remind the operator not to "clean" the hot nozzle at the gate. If the operator happens to see a small piece of stainless steel at the nozzle of the mold accessory, it may be a point nozzle component. Cleaning up this seemingly obstructive thing often ruins the hot mouth. To avoid damaging the hot nozzle, please confirm the nozzle type of the hot runner system before taking action and ensure that all operators are well-trained and able to identify the different types of nozzles they come into contact with.
4、 Sliding buckle. For machines that run continuously throughout the year, this task should be performed once a week. And the end of the year is a great time to perform a routine lubrication and maintenance on these parts.
5、 It is recommended to clean the top pin thoroughly with mold cleaner every 6-12 months. After cleaning, apply a layer of lubricant on the top pin to prevent scratches or breakage.
The above points are the experience summarized by Kunshan Xuanrun Precision Machinery Company through practice. We hope that in the future, mold parts maintenance can be helpful to everyone.
