In summary, if you are using thin plastic like 1/16" thick, just use a pair of scissors. If the plastic is a little thicker, then you will need to use a scribe tool and break over a sharp straight-edge table. If the plastic is thicker than 1/4", then you will need to pay a specialist to cut the pieces for you.

Need a custom switching system for a model

Let's say you were building a small toy that such as a remote control car. I need parts cut from plastic. Is there a kit to do this at home or would I need to go to a specialist?

How thick is the plastic?

If thin like 1/16", just use scissors. If a little thicker like 1/4", use a scribe tool like you can get at Tap Plastic, and break over a sharp straight-edge table.

Thicker than that -- I usually pay Tap Plastic to cut those pieces for me.

Most hobbiest do this with a cutting edge attached to a soldering iron. Rough cuts can be done with a Dremel. I've been known to use a straight pin held in pliers and held over the gas flame from my stove.

Industrial applications use a bit more complex version of what Danger mentioned. They use a wire that has a current running through it to heat it. It acts like a coping saw. Cuts like buttah.

The other options are to try casting,
thermoforming, or fiberglass modeling, or stamping
some of the parts.

If you can cast them from liquid rubber/plastic, just make
a mold from clay or such and pour away then trim when
cured.

If you thermoform, just make a mold out of something like
clay, plaster, sand & glue, or whatever, take the
appropriate semi-thin sheet of thermoformable plastic,
drape it over the mold, heat gently (e.g. hair dryer,
heat gun, or very carefully controlled time in the oven on
low heat), and apply gentle pressure to form the pliable
soft warm/hot plastic over the shape you're trying to
mold it to fit. Cool and trim.

Fiberglass modeling is like paper mache, just get your
resin and some small pieces of matrix (fiber glass cloth,
cheese cloth, gauze, newspaper, whatever is appropriate),
dip/paint them with a thin coat of the resin, let dry.

Stamping, just like using cookie cutters to make
shaped cookies. Make the outline of a stamp shaped
like the part you want in something like sharp sheet
metal from a tin can, or carve the outline with a dremel
tool, sharpen the edges, and press it hard against a
relatively soft / thin plastic sheet to make as many
copies of that cutout shape as you need. Works well
with stuff like soft vinyl, thin HDPE (plastic milk jug), styrofoam, rubber, teflon, etc.

Some kinds of plastic like delrin, teflon, HDPE,
paraffin wax, etc. you can just directly carve and file
and cut with tools like x-acto knife, dremel / rotary tool,
files, etc.

Nice post, Xez. :cool:
 

What is a switching system?

A switching system is a device or set of devices that allows for the connection or routing of electrical signals between different sources and destinations. It can be used in various applications such as telecommunications, power systems, and computer networks.

Why do I need a unique switching system?

A unique switching system may be necessary if you have specific requirements that cannot be met by off-the-shelf solutions. This could include the need for specialized features, compatibility with existing equipment, or the need for a customized solution to fit your unique needs.

What are the benefits of a unique switching system?

A unique switching system can provide a more efficient and effective solution for your specific needs. It can also offer greater control and flexibility in managing your system, as well as potentially reducing costs in the long run.

How do I choose the right unique switching system?

Choosing the right unique switching system will depend on your specific requirements and the capabilities of the different options available. It is important to carefully evaluate your needs and compare the features and specifications of various systems to determine which one will best meet your needs.

What factors should I consider when designing a unique switching system?

When designing a unique switching system, you should consider factors such as the number and type of inputs and outputs, the required speed and capacity, compatibility with existing equipment, and the level of control and programmability needed. It is also important to consider the potential for future expansion or upgrades.
