Action Steps
The best contacts and resources to help you get it done

Find the right size wax injector for your needs

While you want to have enough wax prepared to produce a good amount of product, having a large amount of excess will only waste money. The wax in your wax injection molding machine should be replaced every two to three months. So, you should try to estimate your wax usage and buy an accordingly sized injector. If your injector does not come with an air compressor (and most don't), you will need to purchase that as well.

I recommend: Lacy West Supplies offers wax injection molding machines in a variety of sizes and voltages. Rosenthal offers both standard and digital injection molding machines in several capacities and voltages.

Purchase the correct type of injection molded wax for your product

Injection molding wax comes in many varieties and colors. Though the colors do not affect the finish product, many users prefer the darker colors for more intricate designs to aid inspections by making the details and any imperfections more noticeable. They also have differing characteristics, resulting in molds that are more flexible, durable or with higher or lower opacity.

I recommend: The Freeman Manufacturing & Supply Company provides a wide variety of injection mold waxes in flake form. KerrLab also provides a number of mold waxes, including one type that results in a durable mold that can withstand carving.

Find a wax injection molding distributor that offers a variety of accessories

The injecting machine and plastic injection wax are top priority tools in wax injection molding, however, they are useless without other molding accessories, such as mold frames, plates and thermometers.

I recommend: The Contenti Company offers several dial thermometers for use in injection molding. Though most injector machines come with internal thermometers, these only measure the temperature of the machine and not necessarily the wax. A separate thermometer will ensure your wax is truly at the optimum temperatures. FDJ On Time provides a wide variety injection molding accessories such as mold frames, plates, mold holders and clamps.
