The first Solution to Solve Mold Cracking, Erosion
Grind the mold area and create a new sprue well by enlarging the old one- This practice is only a temporary cure yielding mixed results. Though the mold is repaired, […]
What are Water Cooling Concerns?
All water-cooling systems require proper maintenance to ensure the passages do not become clogged with scale from minerals in the water. To combat this issue, […]
Spray or Vaporization Cooling of Permanent Molds
Spray or Vaporization Cooling of Permanent Molds-In this cooling system design,vertical passages in the mold are sprayed with water from nozzles located in the top manifold. […]
The cooling technique in permanent molds
The cooling technique also presents problems during the drilling of the passages.This method allows drilled cooling passages to be placed precisely in the mold; […]
What are Air-Cooled Permanent Molds?
Air-cooling represents one of the simplest methods of permanent mold cooling. However, this method has limited cooling capabilities because the heat transfer from the mold to the air often isn’t fast enough for the production levels required by most foundries. […]
What are Water-Cooled Permanent Molds?
A variety of different designs for water-cooled permanent molds exist each with its own advantages and disadvantages. […]
Cooling water conditions for selected cooling circuits

Flow Rates for controling mold cooling
With the preceding basics in mind, let’s look at some cooling conditions in actual molding situations and some data taken from lab experiments. […]
Temperature Control in mold cooling
In some cases you may want slower flow, and special systems are available for these situations. […]
what is Turbulent flow in mold cooling?
Let’s start with some engineering basics. Most of you have heard something about turbulent flow and that it is good for cooling. […]
