In injection-molding and extrusion processes, water or air cooling is used to regulate
the temperature of the molding process and remove excess heat cause by shear. A simple, closed-loop temperature control system typically involves the input of heat, a sensor and a controller.
Submerged combustion is a method of direct-contact heating that has been practiced in a range of industries for several decades. This article explains the basic concepts of submerged combustion. It can be applied to process heating of industrial aqueous solutions and slurries as well as to the evaporation of solutions for the purposes of concentration or volume reduction.
Smart temperature management and control are important in applications ranging from hot runner injection molding in the plastics industry to form, fill and seal systems for packaging, to rubber molding and to food production.
An infrared premelter emits a flash of heat (infrared energy) to the top of food products to gently fuse ingredients together. This process reduces product waste during packaging and distribution processes. It also enhances product appearance and presentation.
Researchers at Stanford and IBM Research developed chemical approaches that could efficiently generate biodegradable plastics suited for manufacturing products, including forks, medical devices and fabrics.
