The Best Injection Molding Machines for Do it Yourselfers and Desktop Users from Sandra Brown's blog

At least a portion of any product available on the market today is comprised of items created through injection molding; it is one of the most efficient manufacturing methods available because of its ability to mass-produce plastic objects at a low cost. Products made through injection molding can be found everywhere, from bottle caps to plastic smartphone housings.

Factors to consider
Cost: injection molding machines can be quite expensive, but the availability of DIY options has made them more affordable for hobbyists in recent years. The cost of the machines we've included ranges from $200 to $5,500, depending on their features.
The ease with which it can be used:injection molding is by its very nature straightforward:In a microwave, heat the plastic and spray it into the mold. The machines should be just as simple to operate as they are to operate.
Heat range: The temperature range of an injection molder determines the types of plastic that can be used in the machine. All of the machines on this list will operate at a maximum temperature of at least 400 degrees Fahrenheit (205 degrees Celsius), making them suitable for processing materials such as PE, PP, PS, acetal, acrylic, EVA, TPE, PLA, and ABS. Other plastics can only be processed in machines that operate at higher temperatures.

Buster Beagle 3D is a computer-generated character.
If you're looking for a well-documented and reliable option, the Buster Beagle 3D build was inspired by the LNS 150A and the Galomb B100, both of which we'll cover later in this list, and is a good choice. The Buster Beagle 3D injection molder is a completely DIY solution that is built around a drill press frame and utilizes common off-the-shelf components to deliver a durable {anchor} experience to the user.

In terms of instructions, BeagleBone3D has uploaded a comprehensive video tutorial that goes over the design as well as helpful hints on how to construct this machine. Safety considerations and modifications are also covered in the tutorial, and a number of videos on topics such as mold creation and plastic recycling can be found on the YouTube channel. There is also a Facebook group for anyone who is interested in building this machine and would like to share their progress or ask questions about it.

Precious Plastic is a non-profit organization dedicated to the reduction of plastic waste. Their {anchor} machine has an impressive capacity, with a shot size of 146 grams of polypropylene and a very large shot size. This press has a shot size that is nine times larger than the other machines on this list, allowing it to produce much larger items such as phone cases and plant pots. Four independent heaters are used to maintain a stable temperature throughout the entire heating chamber, which is necessary for such a large shot volume.

Galomb B-100 is a bomber with a 100-pound payload.
In addition to several pre-made molds, Galomb's website offers a variety of resources for those interested in doing their own {anchor} projects.
