When it comes to plastic prototype development or plastic product manufacturing, it is useful to understand which material to use. Typically, there are two types of plastic materials: thermoplastic and thermosetting resin.

Thermoplastic materials are those that can be melted and cured (hardening the polymer material) again and again. There is, of course, a limit to the number of times such melting and curing process can be repeated, depending on the type of thermoplastic material. The point, however, is that such thermoplastic materials can be melted a number of times without degrading the material.

Thermosetting materials, on the other hand, are those that can be melted and shaped only once. After a thermosetting material is cured, trying to melt it again would cause the material to burn, rather than melt. Think of a 2-part epoxy to understand a thermosetting material. Before mixing with the hardener, the epoxy resin is in the liquid state. Once the resin is mixed and dried, it is not possible to heat and melt it again.

When it comes to plastic injection molding, it is easy to misjudge the importance of thermoplastic and thermosetting materials. By the way, both thermoplastic and thermosetting materials can be injection molded. The major difference, when using a thermoplastic or thermosetting material, applies after the injection molding cycle when the molded plastic solidifies. During the molding process, plastic is heated and injected into a metal mold. To get to the cavity of the metal mold, however, the molten plastic first needs to pass through an array of entry points and tunnels known as sprues, runners, and gates. The plastic cools within the mold cavity as well as inside the channels that lead to the mold cavity. The plastic that solidifies inside the channels is not the component or part of the final product. It is just a waste.

Now, what happens to the “waste” during plastic injection molding?

Thermoplastic Materials

If a thermoplastic material were used for injection molding, the waste could be recycled and used again. The solid plastic left within the sprues, runners and gates can be combined with the raw material that goes into the injection molding machine. The same thing can happen with the material from rejected plastic parts. All the waste plastic can be collected and recycled back to the onset of the process. This all sums up into higher efficiency, and eventually means, lower costs of the final product and better margin for the producer.

Thermosetting Materials

If a thermosetting material were used for injection molding, the solid plastic from the sprues, runners, and gates is simply a waste, which has no practical use whatsoever. This means that the cost of the final product will be more.

To conclude, thermoplastic materials offer some major benefits to plastic product manufacturers, consumers, and even the society, as such materials are recyclable. Indeed, when it comes to plastic prototype development or plastic product manufacturing, the manufacturer should choose and use thermoplastic materials.
