1. Used for maintaining the mold temperature and a faster molding cycle.
2. Basic guideline:

• h>2d(Min. 0.75”);
• W>7/16”
• P=3d~5d(35~60mm);
• the Min. distance between e.j. pins and waterlines :1/4”;
• Check for leaks with a pressure of 60 PSI;
• Try to minimize the length of one cycle.

3. Baffles

4. the blocking of W/L

4.1 Brass pressur plug(from DME or HASCO).

4.2 pressure fit by brass

4.3 pipe thread

5. O-ring. Attempt to minimize the use of Oring in the mold design.

5.1 the preferred supplier: Parker and Hasco

5.2 O-ring used for the rotation and axial movement

6. the pipe plug data.
