También aprenderá a pintar, lijar y

enmascarillar para aplicar

acabados superficiales al PET.

Objetivos

ThermoformingIs a process where a plastic sheet

(thermoplastic material) is heated to a high-enough temperature that it can be stretched into or onto a mold and cooled to a finished shape.

The thermoforming machine uses a vacuum to suck up the air and attract the plastic to the mold and get its form.

Termoformado

Consiste en calentar una lámina de un termoplástico el cual, al momento de presionarlo contra una pieza rígida (molde) y aplicando una succión (vacío) adquirirá la forma de dicha pieza.

Project 1: Mold design and blister pack

Los blisters is a pre-formed plastic packaging used for several goods as foods, pharmaceutical, cables, etc.

Proyecto 1: diseño de moldes y blister

Los blisters son envases de plástico transparente fabricados por termoformado que se adaptan al producto y lo protegen.

Basic process: model > packaging

Packaging

POP

Appearance models

Products: Lamp

The teacher will assign a product to each student, who is going to design it’s packaging:

• Plastic protection (PET)• Basic marketing: logo and mark use• Graphic design

Nota: the packaging must be as real as possible, with all the characteristics needed to understand it.

Requirements

Se le asignará un producto a cada alumno y deberá diseñar el empaque del mismo que constará de:

• Protección plástica (PET)• Aplicación y uso de marca• Diseño gráfico

Nota: debe ser lo más realista posible, con las características del tipo de blister que proponen.

Requerimientos

Moldes•Cuidar que la pieza del molde sea rígida

•Materiales: volumen en batería, madera, mdf, yeso, o un material resistente al calor y a la presión.

Molds•The mold must be made with rigid and solid

materials

•You can use: wood, bateria, mdf, plaster cast, must resist high temperatures (heat).

Molds•Keep rounded corners, all the walls must have a certain angle to remove from its mold (no 90°, no L).

•You need a base for the mold, and it needs little holes to let the machine suck up the air.

Moldes•Redondear las esquinas,

evitar planos a 90° para evitar que se formen pestañas, deformaciones o rechupes.

•Si se usa una base, hacer pequeños agujeros a la misma para que por ahí succione el aire.
