Hello i want to make something from plastic, I will need something like a form for it, got a suggestion on how to make it and from what to make it? the dimensions of the thing will be like 20cm x 10cm x 3 cm it will actually be a blade for my floor ball stick. i will also need plastic for it so suggest me where to buy and which or which one could i re-use something like the plastic bottles. gt;D thanks in advance
formed plastic is made from high heat and high pressure...the plastic is usually melted in a controlled way so it does not burn. Industry starts with uniform pellets which are then melted into a very thick medium. HIgh pressure air is usually used and is also warmed too to add to the molding effect. Molds are made out of Aluminum or steel alloys. They usually make a mold from solid aluminum, precisely grinding out the image into the aluminum, then one or more blow holes are added in both halves of the mold. THe mold is made into 2 pieces, halves, which will come apart easily too. THe temperatures that they deal with are between 500 and 1000 Fahrenheit, depending on the type of plastic....greater than that would cause burning. So if you have 5000 to 50000 laying around to invest into a blow molding machine then youcan do this. BUT...I would strongly suggest you forget about plastic and go with Fiberglas instead. Any marine or autobody shop or auto supply will have the materials. You'll also need an Organic filter mask, very good safety glasses, and thick plastic gloves or neoprene gloves. Make your mold out of wood and if for fiberglas then make the wood mold so that the fiberglas liquid does not escape., then pour the fiberglas mixture OR spread bondo over the wood around the mold. use the fiberglas strengthening tape or lath to reinforce the fiberglas or bondo. Then after 24 hours...remove the mold and carefully sand around it to smooth out the edges. Fiberglas or Bondo is much easier than plastic.
