Feeders are auxiliary equipment used for in-line additive dosing and are often used with an injection molder or extruder. There are two main types of feeders: gravimetric and volumetric. The choice between a gravimetric feeder and a volumetric feeder is a critical decision that profoundly influences the outcome of the plastic manufacturing process. Both play indispensable roles, yet they differ significantly in their operational principles and applications.

Single-Cavity vs. Multi-Cavity Injection Molding: Which Is Right for Your Application?
Injection molding revolutionized the plastic manufacturing industry by enabling companies to produce identical parts in medium and high volumes quickly, efficiently, and cost-effectively. It’s for this reason that manufacturers often prefer to follow the injection molding process over using CNC machining, die casting, and urethane casting methods.
What Is Profile Extrusion, and How Is It Different from Other Extrusion Methods?
Plastic is a popular raw material in a variety of manufacturing industries because it is cheap and versatile. Many of the products we enjoy today, such as PVC pipes, drinking straws, and window trimmings, wouldn’t be possible without the plastic profile extrusion process. What is profile extrusion?

How a Gravimetric Blender Works
When you need high-precision dosing for extrusion and plastic injection molding, you will want to install a gravimetric blender onto the line. This piece of equipment can decrease blending variability from overdosing colorants and additives by allowing plastics processors to measure materials accurately. Let’s examine how gravimetric blenders provide blend accuracy even when there are bulk density variations among materials.
The Importance of Gravimetric Blender Maintenance
The main draw of using a gravimetric blender in your production process revolves around how accurate measurements it produces with each use. You can save a lot of time and money, thanks in large part to this accuracy. Gravimetric blenders are complex and intricate machines with many different components working together to ensure it works correctly. These machines run for hours on end and often find themselves integral parts of the production process. For each blender to do its job well and perform a perfect blending of materials each time, you want to have an established maintenance routine in place. Regular maintenance will help keep your gravimetric blenders working as intended.
