Why is my injection molding machine leaking water?

Defective Valves or Pumps: Leaking valves or pumps within the injection molding machine can lead to material leakage or water leaks. Solution: Regularly inspect valves and pumps for signs of wear or damage. Implement prompt repairs or replacements to prevent further leakage issues.

What causes injection mold cooling water leakage?

Injection mold cooling water leakage is often occurring for many reasons, mainly in the following areas. 1. the most occurring at the joints of the cooling water pipes of the mold, if the leakage is found, the sealing tape should be wrapped around the threads of the pipe joints and then tightened. 2.

What should I do if my water valve leaks?

Be sure to blow out thoroughly all external water-fitting counter-bores and other cracks, slots, and holes where water can lie and leak out. Usually you can now reopen the water valves and watch for the leak or drip to reappear.

Why do molders have water leaks?

In the molding business, water leaks come with the territory, but they cost molders thousands of dollars in labor hours and lost product. Most root causes of leaks are simply oversights, failure to exercise caution during mold assembly and installation, and a lack of proper final check procedures.

Why do tooling & O-rings leak?

Tooling and o-rings often leak only when under clamp or injection pressure, conditions that cannot be replicated on the bench. Other times, set-up technicians will notice water dripping from the bottom of a mold and pull it without first determining which half, quadrant, or general area the leak is coming from.

How to fix a leaking cooling water pipe?

For the cooling water pipe buried in the mold, the mold should be decomposed to remove the rust. After inspection and repair should be carried out a leak test, using the hand pump to fill the water hole, keep 5min under 2MPa pressure, and judge whether the water hole is leaking by observing whether the water pressure is reduced.
