A hopper loader, often referred to as a material loader or auto loader, is a device used in industrial settings, particularly in plastic processing and molding industries. 

Its primary function is to automatically load plastic resin，such as ABS, POM,PC,PBT.PP,PV  or other materials into processing machines like injection molding machines or extruders.

Greatly improved work efficiency in plastic industrial

The hopper loader operates by creating a vacuum or using compressed air to convey raw materials from a storage container (such as a material bin or drum) to the processing 

equipment's hopper. 

This process ensures a consistent supply of materials, facilitating continuous production without the need for manual intervention to refill the machines.

Hopper loaders come in various sizes and configurations to accommodate different production needs.
