Abstract The working conditions of the plastic mold are complex. They touch directly with the plastic, withstand the pressure, temperature, friction and corrosion and so on. The main failure modes of the plastic mold surface wear, deformatio...

Abstract： An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same in a refrigerator as in...

Air conditioning controls the temperature, moisture, cleanliness, and movement of indoor air. It cools the air when the weather is hot. It warms the air when the weather is cold. Comfort depends partly on humidity, and air conditioning remov...

The purpose of this book is to introduce the reader to some topics relevant to the modeling of the injection molding process. Injection molding processing links to various scientific and engineering disciplines such as rheology, mechanical...

The rapid heating cycle has the advantage of improving product quality in injection molding. In this study, steam heating was combined with cool water on the same mold design to achieve dynamic mold surface temperature to establish control....

10.1 Introduction Heating is the first word in the acronym HVAC. It is the most impor-tant part because without heating mankind would have difficulty in surviving. Proper design of the heating system is even more critical than that of vent...

Abstract Fiber-reinforced polymer (FRP) tendons and reinforcing bars (rebars) have been developed for use with concrete. FRP products are non-corrosive and lightweight when compared to traditional steel members. The current test program invo...
