Plastic grow kit design project

Abstract

Objective: The development of a product aimed at the recreation sector such as toys for children can represent many obstacles due to the public to which it is addressed and the problems that come to reflect with the efficiency of the plastic material and how that can affect the product itself. Method: Our starting point in this project was to make research about products that were already made, we had to became familiar with the materials commonly used for the invention of toys, know its properties until we find the ideal material for our product which in the end it turned out to be the HDPE of SABIC. Then based of previous knowledge we wrote the functional analysis of the product to characterize the functions offered by our product to satisfy the needs of our users. Next, we capture the ideas in a pulse sketch to be able to later make an electronic sketch with the help of a SolidWorks to make the idea tangible and do the necessary changes to the problems that progressively presented themselves to us. In fact, the invention of the toy evolved as we went along, this was precisely the strongest barrier of the whole assignment. Furthermore, we decide based on our judgment and research that the best method to make our culture kit was through injection, because it benefits us in the aspects of time and cost of the process. Consequently, we had the task of carrying out mechanical resistance tests in the Mold Flow software to ensure that our design was practical. Contribution: Finally, we had to obtain the approximate cost of machinery in the production invested on our piece, which gave us a cost of about 4.938 €. And that helped us to obtain countable results from simulations, such as the cycle time.
