You should have already accurately measured its resistance when using an electric heater in the plastic mold factory at the beginning, and at the end of the year, you should accurately measure it again and compare it. If the resistance value fluctuates by ±10%, it is time to consider replacing the electric heater to ensure that it is not prone to common failures at critical junctures in the process. If no plexiglass product has ever accurately measured the initial resistance value, then make an accurate measurement now, and use the personally obtained standard value as the reference data information when checking the electric heater in the future.

5. Check whether there are signs of damage between the positioning pin and the guide bush. Find out if there are scratches or scratches on furniture hardware accessories, such mold accessories are damaged due to lack of moisturization. If the impression is only just appearing, then you want to be able to add lubricating fluid to the given dowels and guide posts to increase their life. If the damage is serious, it should be replaced with new parts.
