Hopper Loader and Feeder

Hopper Loaders

Function

Automatically convey plastic pellets, granules, or powders from storage containers or silos to processing machines (e.g., extruders, blow molders).

Features

Vacuum-Powered Operation: Utilizes negative pressure to suction materials without dust leakage.

Adjustable Loading Speed: Customizable feed rates (10–1,000 kg/h) to match production demands.

Integrated Filters: Self-cleaning mesh filters prevent blockages and maintain airflow efficiency.

Material Compatibility: Works with virgin resins, recycled plastics, and hygroscopic materials (e.g., nylon, PET).

Screw Feeders

Function: Precisely meter and deliver materials using a rotating helical screw, ideal for controlled dosing or blending applications.

Features:

Variable Speed Control: Adjust screw rotation speed for accurate material flow (0.1–500 kg/h).

Modular Screw Designs: Stainless steel or abrasion-resistant screws tailored for powders, flakes, or fragile pellets.

Closed-Loop Systems: Minimize exposure to moisture and contaminants during transfer

Parameter

Application

Blow Molding:
Hopper loaders ensure uninterrupted PET or HDPE pellet delivery to blow molding machines, preventing production stoppages.

Plastic Extrusion:

Sheet/Film Extrusion: Maintains consistent material flow for PP, PVC, or ABS sheets, reducing thickness variations.

Pipe & Profile Extrusion: Hopper loaders supply high-volume resins (e.g., UPVC) to extruders, while screw feeders blend stabilizers or pigments.

Injection Molding

Automated loading of engineering plastics (e.g., PC, POM) into injection units, optimizing cycle times.

Recycled Material Processing

Contamination Control: Filters in hopper loaders separate debris from recycled flakes, ensuring clean material input.
