Injection molding is used to make the vast majority of plastic products seen on the market today. Traditional CNC machined metal molds have very high prices and long lead times for low-volume production, despite being a perfect process for large-scale production needs.
3D printed injection molds are a time and cost-effective alternative for low-volume production. They are also less expensive than CNC machining. This article will guide you through the whole process of DIY injection molding and give you all of the tools and tips you will need to learn how to mold plastics at home.
Injection molding is basically a manufacturing method that involves injecting molten material into a mold. Injection molding plastics at home can be carried out using various materials. They include metals, glassware, elastomers, confections, and, most typically, thermoplastic and thermosetting polymers. The part’s material is first supplied into a heated barrel, mixed, and then injected into a mold cavity. That is where it cools and hardens according to the cavity’s configuration.
Molds are usually manufactured by an injection mold-maker from metal, usually steel or aluminum, and precision-machined. That is done so as to form the features of the required part after a product is conceived. The process is usually done by an industrial designer or an engineer in a company that provides a plastic injection molding service. Injection molding is a popular method used for producing a wide range of parts, from minor components to whole bodies.
We all agree that carrying out the injection molding process is not cheap. That is still the case in plastic injection molding at home. You will need a number of tools and materials to get started. It takes a good amount of cash to set up a system for DIY injection molding. On the other hand, getting the correct equipment and going through the whole learning process of how to use it will cost you both money and time.
Individuals still go for the DIY injection molding process because the prices involved are still less than the cost of a single metal mold. The time and money saved after you’re up and running will readily compensate for the initial effort.
Always make sure you compare the injection molder to your production needs before making any purchase. Industrial techniques will still be required for significant parts. This DIY injection molding process works best for creating small parts in limited quantities. Let us look at the items needed before you get started.
The specific strategy to DIY injection molding will differ depending on the intended design and volume but the following pointers can help you improve your chances of success.
