If you’re looking to become a plastic molder, the two main things you should consider are your plastic injection molds and the materials you’ll use to create parts. Before setting out to have your mold designed and made by Quality Mold Shop, you should consider the purpose of the part you plan to create.
Different plastics have different properties, making some more suitable for certain jobs than others. If you take a look around you, noticing different things made from plastic, you’ll notice how similar plastics are always used to make similar products.
Your laptop case, for instance, will always be made from a hard plastic rather than a soft one. If you examine the properties of the plastic used to make laptop cases, you’ll notice that the plastic doesn’t really give way or bend easily. It’s hard, yet it’s durable enough to not break or crack easily if it gets a light knock. The lid on your lunch box, on the other hand, isn’t hard like that. It’s a soft plastic that easily bends and gives way. This can help it to stretch a little over the lunch box container, creating a stronger seal.
