Do-It-Yourself: Plastic Molding

Setting up my own system?

First you have to put together your mold. There are several ways this can be achieved. Many people use RTV in either poly or silicon based units to create their two part molds, by making a negative of the part you are going to copy. Take for instance the question in my comments: broken lawn darts. This casting set should likely be in three pieces to allow for easy separation of each Fletch vane. I would use the best of the darts. Oil them with WD-40 or other slippery substance that silicone would not stick to. Next smear a very liberal amount of RTV on six small pieces of quarter inch paneling board. Make sure there will not be any bubbles.

Then carefully place each wet silicone piece onto the fletch vanes, making sure that all areas of the lawn dart are covered. It would be good to mark the individual pieces now with a marker. Wait a day or so for the RTV to cure. Using a utility knife, carefully separate the individual pieces. Hindsight in my own mistakes says to make sure you have also bonded the six pieces into three with a bracing piece. This can be siliconed in place as well, but make sure that your vanes are spaced evenly. Doing this properly will help in making sure your parts align properly for the next steps.

Once you have removed the original lawn dart from the mold, use your knife to open three small weep holes on the fletching edge of each vane. Next clamp your mold pieces together in the proper order. Then using a liquified plastic solution, usually created by dissolving the proper plastic into a solution of plastic weld glue. For the thin vanes of the fletching, particulate powder can be used, but being consistent in the fletching will be next to impossible. The ideal scenario would be to use the injection method after softening the injected plastic.

With this said, metal tipped lawn darts have been banned from use in the US and Canada because of injury and death. Parts can be imported, but kits and complete units are impounded by customs. This is not something to make to sell. However, this product is like the proper handling of a handgun. Education is essential for proper use. Use common sense. Anyone participating in a lawn dart game must understand that in 1988 the Trade Commission banned them after three deaths and a seven year old boy in Indiana suffered irreparable brain damage due to the metal tipped lawn darts.

Other Ideas

You could also use a ceramic or metal form to pour your liquid or powdered plastic into then heat or let set. Now let me be clear I’m not only saying a form made from metal or ceramic. I’m saying that the form could be made of anything as long as it with stood the heat of the molding process. Scrap wood can easily be shaped by standard wood working tools and made into the negative of your part. Of course, RTV Silicone mentioned above is a decently cheap method if you do not mind the smell.

For one piece molds, there are any number of ways to vacu-form your molds, using old vacuum cleaners and ovens to soften the plastic you will use for your mold. This might be handy for making a repair piece for an old doll or action figure. It is a method used often times by the plastic modelling community for numerous parts.

The four basic types of molding (particulate, pour, vacuu-forming and injection) could be used for a long time for manufacturing.

But are you going to mass produce your project? Are you going to need a quick setting system for a more rapid production?

Injection molding alone is used for many different industries. In essence, Injection Molding is using a machine to squeeze the hot or chemically melted plastic into the mold. Injection molding mated to the particulate molding process, can speed your production considerably, as well as, as mentioned before, quite possibly making a stronger product. Keeping your equipment clean helps keep the fumes at bay as well. Stray plastic material can out gas for a long time after it has melted, and every time it is heated releases even more fumes.

I had thought that by this time I would have figured out a better system but arc heating and torch/flame heating are out of the question because of keeping the fumes to a minimum. So for now I use an array of several old soldering irons that are placed strategically around the mold to help in the even heating. However, that is a very inefficient system so I have been working on a new one that uses a small chamber and direct blown heat from that chamber.

Plastics Designed And Engineered For Use In Medical Equipment

Where would the world be without plastics. The high molecular density and malleable material has so many applications that it would be impossible to imagine the world without them. Touching our everyday life from food and beverage packaging, packaging in general including disposable bags to panels in our motor cars and quite a few parts of spacecraft are molded and then machined from plastics.

There are a myriad different grades of polymer that make up the plastics we use today, from poly carbonates and High density polyethylene (HDPE) to Polyethylene

Terephthalate (PET) and poly propylenes and so on. Each of which have distinct properties and when a product is being designed the type and grade will be selected for the most desirable of qualities.

A medical device engineer will know all of this because in the medical field plastics have thousands of uses. From simple vacuum sealed bags for sterile gloves, dressings and instruments and syringes, to the material used in contact lenses, to the use of fiber optic cables and probes to prostheses. And these are just some applications, obviously the control panels and housing of most medical machines are made in part, if not completely, with plastic of some type or another.

In the design , production and application of plastics for medical applications there are few to rival this medical device design company . Medical device in San Diego compete is a very specific market, they are aware of the regulations imposed by the FDA and the fact that is they make errors and sterile equipment gets contaminated or the contact lenses either break down or change shape the consequences could be dire.

Eric R Larson is a world renowned plastics engineers and helps medical device design companies converting concepts into realities by series of interventions and specific tasks undertaken to determine the best plastic for this application considering all factors , strengths and tolerances required. Then determining the method to be used. (Pressure Molding, Blow molding, extrusion and so on) and then will assist with the design of the tooling for the machinery required to manufacture and produce the item concerned, whether it is to be a huge production run or just a few limited items.

On the Plasticsguy Blog is a series of simple and straightforward articles written by Eric R Larson which discusses in fairly non technical language the properties of a huge range of the plastics in current uses and in use in the medical industry.

For example the section on Polycarbonate is sub headed “the king of all things clear” and continues with” Polycarbonate is an amorphous thermoplastic with a fantastic balance of properties. It is stiff, strong, has good ductility and exceptional impact resistance” and discusses its use in such things as the canopies of fighter jets.

The blog is a work in progress there is a lot of detail already there demonstrating his in depth knowledge and expertise.

Thus all medical device companies in San Diego are encouraged to visit his blog and read his discussions on the various types of plastics and the applications they can be used for.

World’s first 3D printer in space will launch this month

The first 3D printer ever to fly in space will blast off this month, and NASA has high hopes for the innovative device’s test runs on the International Space Station.

The 3D printer, which is scheduled to launch toward the orbiting lab Sept. 19 aboard SpaceX’s unmanned Dragon cargo capsule, could help lay the foundation for broader in-space manufacturing capabilities, NASA officials said. The end result could be far less reliance on resupply from Earth, leading to cheaper and more efficient missions to faraway destinations such as Mars.

“The on-demand capability can revolutionize the constrained supply chain model we are limited to today and will be critical for exploration missions,” Niki Werkheiser, manager of NASA’s “3-D Printing in Zero-G” project at Marshall Space Flight Center in Huntsville, Alabama, said in a statement. [3D Printing in Space (Photo Gallery)]

3D Printing in Zero-G is a collaboration between NASA and California-based startup Made in Space, which built the machine that’s heading to the space station this month. The microwave-size 3D printer was cleared for flight in April after an extensive series of tests at Marshall.

3D printers build objects layer by layer out of metal, plastic, composites and other materials, using a technique called extrusion additive manufacturing. NASA hopes Made in Space’s device works normally aboard the station, thus demonstrating that 3D printers can produce high-quality parts in space as well as on Earth.

If that turns out to be the case, replacing a broken part or tool aboard the orbiting lab could be a matter of simply pushing a button.

“I remember when the tip broke off a tool during a mission,” said NASA astronaut T.J. Creamer, who lived aboard the space station from December 2009 to June 2010. “I had to wait for the next shuttle to come up to bring me a new one. Now, rather than wait for a resupply ship to bring me a new tool, in the future, I could just print it.”

It will likely take the 3D printer from 15 minutes to an hour to print something aboard the space station, depending on the size and complexity of the object, researchers said. Blueprints for desired parts can be loaded onto the machine before launch or beamed up from the ground.

“This means that we could go from having a part designed on the ground to printed in orbit within an hour or two from start to finish,” Werkheiser said.

While the space station is the proving ground for this test, NASA officials see great potential for 3D printing beyond low-Earth orbit. For example, deep-space missions could benefit greatly from the technology, because it would be tough to ferry a spare part to a vessel already on its way to an asteroid or Mars.

“NASA is great at planning for component failures and contingencies. However, there’s always the potential for unknown scenarios that you couldn’t possibly think of ahead of time,” said Ken Cooper, principal investigator at Marshall for 3D printing. “That’s where a 3D printer in space can pay off. While the first experiment is designed to test the 3D printing process in microgravity, it is the first step in sustaining longer missions beyond low-Earth orbit.”
