At the Technological Institute of Los Mochis, there is currently no furnace for heat treatments, so students of the careers of Industrial Engineering, Electromechanical Engineering and Mechatronics Engineering do not have the necessary tools to carry out practices in the subjects of Engineering of Materials and Manufacturing Processes, which is of utmost importance for them to understand some of their properties. The knowledge and mastery of heat treatment processes in Engineering careers is fundamental, because it is precisely at this stage of the academic process that the set of heating and cooling operations are known, under controlled conditions of temperature, dwell time, speed, pressure of metals or alloys in solid state.........

Keywords: Temperature control, heat transfer, heat exchanger, didactic oven.

Background:Plastic materials, currently there are many types of plastics that have been researched and applied in the details and components of machines and equipment from households to companies and factories such as computers, washing machines, cars, air conditioners, etc. The problem for designers and manufacturers of plastic parts that make up machines is to choose the right plastic material for each detail with specific uses in each type of machine or equipment. Designers and manufacturers can rely on the experience passed down from previous experts or from analysis and selection on theoretical documents. So this article provides some information and theoretical data as the basis for choosing the right material for plastic parts......
