With a lower suction design, it has a cyclone baffle and separate dust bucket under the filter, which can effectively reduce the load of the filter;
Separate dust bucket for easy dust removal;
With the electrical control function of the two-ingredient proportional valve, it can be directly equipped with a two-ingredient proportional valve;
The hopper loaders above 5HP are equipped with a vacuum breaking valve, which can effectively increase the suction capacity;
The main machine is equipped with fault and motor overload indicator lights, which can give an alarm quickly;
The central operation panel can be used to centrally set the suction parameters of each station;
The main machine is equipped with a suction overtime and fan overload alarm device.

Vacuum Loader for Injection Molding
1. What is a vacuum loading machine?
A vacuum loading machine is an automatic material conveying device that uses negative pressure to transport plastic pellets, granules and powders from storage containers to processing equipment.
2. How to Select a Vacuum Loader?
| Production Requirement | Recommended Solution |
| Single machine | Single vacuum loader |
| Multiple machines | Central conveying system |
| High output extrusion | High capacity vacuum loader |
| Powder conveying | Powder vacuum receiver |
3. What materials can a vacuum loader handle?
It can convey: Plastic pellets, Resin materials, Granules, Powder materials
4. What is the difference between a vacuum loader and a central conveying system?
A vacuum loader is usually used for single machine feeding, while a central conveying system integrates multiple machines and material sources.
5. How do I choose the right vacuum loader model?
Selection depends on: conveying distance, material type, required output, hopper capacity.
6. Can vacuum loaders be used for injection molding machines?
Yes. Vacuum loaders are widely used for automatic resin feeding in injection molding production.
