Prototypes I2o Parcial: Thermoforming: blister
design and appearance model with pet
February 14th, 2014
Understand and learn about PET and thermoforming properties.
Understand how to make and prepare molds for the thermoforming machine.
Learn how to use and what we can do with the thermoforming machine
Learn how to get different kind of
finish for the PET:
how to cut it, paint it, etc.
Objectives
El alumno aprenderá algunas propiedades del PET, ha hacer volúmenes para obtener moldes, así como el uso y aplicaciones de la máquina termoformadora.
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.

Cut and sand the edge to make it straight
Mask the places you don’t want it to be painted
Mask
Paint
You can use masking tape, paper, plastic bags, etc.
Paint it with aerosol
