MATERIALS & TECHNOLOGIES

1. OBTAINING THE DIFFERENT TYPES OF MATERIALS

   • CARBOARD
     • Paperboard is usually made from pulp, which is obtained by processing wood chips or recycled paper. The pulp is transformed into sheets that are dried and cut to size to determine the measurements for sale or use in our different activities.
   • WOOD
     • Wood comes from trees and because there is such a variety of trees there are more types of wood and of different colors and shapes, wood is used to make constructions and to make paper.
   • PLASTIC
     • Plastic is used for different containers or things to use and to create instruments such as plates, cutlery, glasses, etc.
   • ALUMINIUM
     • Aluminum is obtained from bauxite ore by a process called smelting, which involves heating the ore with a reducing agent to extract the metal.

2. HANDLING OF MATERIALS

   • CUTTING
     • SAW CUTTING:
       • It is used to cut materials such as wood and metal. It can be done with manual or mechanical saws
     • PLASMA CUTTING
       • It is used to cut electrically conductive materials. A plasma jet is directed at the material and is used to cut the material with precision
     • LASER CUTTING
       • It is used to cut materials such as acrylic, plastic, and metal. A laser beam is directed at the material and is used to cut the material with precision.
     • WATER CUTTING
       • Used to cut materials such as glass, stone and metal. A strong jet of water is directed towards the material and is used to cut it with precision and agility.
     • GUILLOTINE CUTTING
       • Used to cut materials such as paper and cardboard. The material is placed in a guillotine which has a sharp blade that goes down and cuts the material.
   • WELDING
     • SOLDERING
       • consists of heating a metal (solder) to a temperature such that it flows and adheres to the components to be joined.
     • MIG / TIG / STICK WELDING /FLUX CORED
       • Uses an electrode or wire which is melted and joined to the base metal (parts to be welded).
     • is a technique for joining two materials into one, usually by melting a material with heat to act as a glue.
   • MOLDING
     • The material model is used to create shapes or pieces of different materials, if they are hard materials, they are melted, put into the mold to get a specific desired shape or piece, there are several types of molds with different shapes.
     • MELTING
     • BLOW MOLDING
     • EXTRUSION
   • ASSEMBLY
     • Material assembly is the process of joining two or more materials to create a finished product. This process can involve different methods depending on the materials being used and the application of the final product
       • METHODS
         • MECHANICAL FASTENING
         • ADHESIVE BONDING
         • WELDING
         • SEWING
         • INTERLOCKING

3. MANUFACTURING THE PROTOTYPE

   • ADDITIVE MANUFACTURING
     • Known as 3D Printing, is a process of building a three-dimensional object by adding layers of material on top of each other.
   • SUBSTRACTIVE MANUFACTURING
     • Laser cutting and CNC milling is a process of cutting, drilling or carving material from a larger block to create the desired shape.
   • MOLD MANUFACTURING
     • Process of creating a mold that can be used to make multiple identical parts. This method is commonly used for creating parts with complex shapes or designs, such as plastic parts for injection molding.
