What is a vacuum mold?
A vacuum mold is a shape that is placed in a vacuum molding machine to produce the finished piece. A hot plastic sheet is lowered onto the mold, and then air is vacuumed out from underneath. This pulls the soft plastic sheet down over the mold, and the plastic takes the shape of that mold. Cold air is blown over the setup for a short time, and the molded plastic sheet, with its molded shape formed in it, is lifted off the mold and sent on for further work.
What is polymer extrusion?
Polymer extrusion is a manufacturing process that involves forcing molten polymer material through a die to create a continuous profile or shape. The process begins with raw polymer pellets being melted and then pushed through a screw or ram system before being forced through a shaped orifice to form the desired shape. The extruded polymer material then undergoes cooling and sizing processes before being cut or wound into the final product.
Who made plastic bags?
The first man-made plastic was created by Alexander Parkes who publicly demonstrated it at the 1862 Great International Exhibition in London. The material called Parkesine was an organic material derived from cellulose that once heated could be molded, and retained its shape when cooled
How is chocolate shaped?
Most chocolate shapes are molded. The warm, melted chocolate is poured into molds or casts in a particular shape or design. When the chocolate cools and firms up, it will come out shpaed like the mold it was in.
What are the similarities between thermo plastic and thermosetting plastic?
There are a few differences between the two. Thermoplastics usually contain additives to change the properties of the material such as polypropylene. Thermosets usually contain catalysts that change the state of the material at the molecular level. The main difference between thermoplastics and thermosets is that: -Thermoplastics can be re-melted and recycled fairly easily -Thermosets typically are cured and molded into shape and are not recycled as easily
What is the playstation portable outer shell made out of and how is it made?
It is made out of plastic and is injection moulded, ie, a metal mould is made with an empty space in the shape of the PSP's outer plates, then melted plastic is injected into that gap so it can set in the shape of the plates.
How can metal shape or molded?
Using heat or pressure.

How do you make tiles from plastic?
One way to make tiles from plastic is to melt plastic in the oven in the shape of a tile. Plastic pony beads are an excellent source for plastic that can be melted into different shapes. In a square metal pan, arrange the beads with the hole facing up in a single layer. Nonstick pans work best. Bake at 350 degrees until the beads are fully melted. Let cool and remove from pan.
Is the heat treatment of polymers possible?
Yes but it has very different effects than heat treating a metal.When plastics are molded a certain amount of what is called molded in stress is applied when the part is cooled. The amount of molded in stress depends on the shape of the part cooling time etc. To reduce molded in stress generally you would increase the mold temperature and increase cooling time. However that gives us longer cycle times which costs money. With that said...Heat treating plastics will help get rid of molded in stresses however will normally cause part warppage. On the other hand when done at lower temperatures heat treating a plastic for a short period of time prepares a plastic surface to be painted.Heat treating a plastic for painting changes the surface energy of the material making it easier to apply the paint and produces a better adhesion.
What is a line bender?
a heat strip heats up and u place the plastic on the strip and you leave it until its melted or softened and you form it into a shape you want then you cool it or let it cool on ots own
