29.  The biggest advantage of a Hot Runner Mold is waste free (no runner).

Bonus 3   In addition to identifying the storage locations, the mold identification must be attached on the shelf.  The following information is useful for the assignment of the molds:   List 2 of the 6 listed

4.   List 3 different examples of items we use every day that made out of plastics.

9.  During the mold design, that is the stage when you decide gate type and location, also a Mold FLow Simulation would give an idea to fill of the part (good starting point).

27.  Three plate molds have advantages in that molded parts and sprue spiders are ejected from two different openning areas of the mold (no trimming gates is nescessary).

49.  Molds should be stored wet and not protected against fire.

23.  Parts with internal undercuts are fundamentally harder to demold.

47.  In  Chapter 9, only a few simple steps are needed daily to ensure the long term production safety of the molds or dies.

46.  In Chapter 9, regular care (PM) of molds pays off in the long run.

Given the general triangle, which is not drawn to scale, and  a=10, b=5 and c=6{“version”:”1.1″,”math”:”a=10, b=5 and c=6″} Find the exact measure of angle A.  If A is a special angle, give me the angle in degrees.  Otherwise, leave it in terms of an inverse trigonometric function.
