SDF-500 Manual Powder Filling Machine

Product Name: Manual Powder Filling Machine Model: SDF-500 Category: Powder Filling Machine / Auger Dosing Filler Supplier: Wenzhou T&D Packing Machinery Factory

The SDF-500 is a compact small powder filling machine built on stepper-motor control technology, electronic weighing technology, and microcomputer control. It delivers a filling range of 5 g to 5000 g (screw replacement required across the range) at a speed of about 20 fills per minute with accuracy within 1%. The operator manually presents bags, cans, or bottles while the machine automatically doses and corrects errors, and it can be matched with a spiral feeder for automatic feed control. It handles powders, superfine powders, and small granules — such as milk powder, seasonings, flour, white sugar, solid beverages, washing powder, and feed additives. One-year warranty with lifetime maintenance service.

1. Product Overview

1.1 Product Category

The SDF-500 is a small manual powder filling machine with auger (spiral) dosing, electronic weighing, and microcomputer control, designed for quantitative dosing and filling of free-flowing and non-free-flowing dry powders and small granules at small scale. The operator manually presents the container; the machine automatically measures and fills.

1.2 Application Scenarios

Typical materials and industries:

Food: milk powder, compound seasoning, natural seasoning, white sugar, flour, solid beverage powder, monosodium glutamate (MSG)
Daily chemical: washing powder, detergent powder
Agriculture & pharmaceutical: pesticides, veterinary medicine, feed, enzyme preparations, additives
Container types: bags, cans, bottles, and other rigid or flexible containers

1.3 Core Functions

Automatic quantitative dosing and automatic filling
Automatic error tracking and correction (compensates for material density and hopper level changes via photoelectric switch control)
Automatic counting and parameter memory
Automatic material cleaning function
Spiral (auger) feeding control with photoelectric sensor measurement
Keyboard-adjustable target weight, continuously adjustable across the range by changing blanking screws of different specifications
Manual container handling (operator presents bag, can, or bottle)
Optional spiral feeder for automatic feed control

2. Core Advantages

Integrated control platform — combines stepper motor control technology, electronic weighing technology, and microcomputer control in a single packaging unit.
High accuracy with self-correction — errors caused by changes in material proportion and material level are automatically tracked and corrected, keeping filling accuracy within 1%.
Wide, adjustable filling range — 5 g to 5000 g on one machine; weight is set from the keyboard and adjusted continuously, with screw swaps covering different specifications.
Compact and lightweight — a small-footprint machine (120 × 120 × 100 cm packaging) that fits small workshops and startup production lines.
Simple manual operation, easy sealing — the operator only presents the bag; the filling mouth stays clean, making bags easy to seal.
Scalable feeding — can be matched with a spiral feeder for automatic material feed control.
Low entry cost with full support — one-year warranty, lifetime maintenance, EXW Wenzhou delivery.

4. Sales Suggestions & FAQ

4.1 Sales Suggestions

Target buyers: startups and small workshops, sample/lab filling lines, seasoning and milk powder repackers, and small-scale pesticide/veterinary medicine/feed additive packers who need low-cost quantitative powder packing into bags, cans, or bottles.
Positioning pitch: the entry point of the powder filling range — a compact, affordable auger filler with weighing-grade 1% accuracy; emphasize small footprint, simple manual container handling, and the 7-day lead time.
Upsell opportunities: spiral (auger) feeder for automatic feed control; different blanking screw specifications for the customer's full weight range; trade-up path to the semi-automatic PDF-500 or the fully automatic ADF-500 as the customer's volume grows.
Compliance talking point: CE certification available — share the CE certificate with EU-bound customers.
After-sales commitment to highlight: one-year warranty with free maintenance or replacement (customer covers freight from China), lifetime maintenance beyond warranty.

4.2 FAQ

Q1: What materials can the SDF-500 fill? It is suitable for powders, superfine powders, and small granules such as compound seasoning, natural seasoning, salt, MSG, milk powder, solid beverage powder, white sugar, flour, washing powder, pesticides, veterinary medicine, feed, enzyme preparations, and additives.

Q2: What containers can it fill into? Bags, cans, bottles, and other containers for powder packing.

Q3: How is the filling weight adjusted? The target weight is set from the keyboard and is continuously adjustable. To cover the full 5 g – 5000 g range, the blanking screw is replaced with a different specification.

Q4: How accurate is the machine? Filling accuracy is within 1%, and errors caused by material proportion or material level changes are automatically tracked and corrected.

Q5: How fast is it? The filling speed is about 20 times per minute, depending on the material and target weight.

Q6: What does manual operation involve? The operator manually presents the bag, can, or bottle under the filling head; the machine automatically doses, weighs, and corrects errors. The filling mouth stays clean, so bags are easy to seal.

Q7: Can the machine feed material automatically? Yes — it can be matched with a spiral feeder for automatic material feed control.

Q8: What are the warranty and after-sales terms? One-year warranty. Under warranty, damage from normal use as described in the manual is repaired or replaced free of charge (customer pays freight from China; engineer travel, if required, is paid by the customer). Beyond the warranty period, lifetime maintenance service is provided.

6. Workflow

Material feeding — powder is fed to the hopper (manually, or automatically via the optional spiral feeder with photoelectric level control).
Dosing setup — the operator sets the target weight on the keyboard; the microcomputer control system drives the stepper motor and auger (blanking screw).
Container presentation — the operator manually places the bag, can, or bottle under the filling head.
Auger filling & weighing — spiral feeding control with photoelectric sensor measurement dispenses the set quantity; electronic weighing technology verifies each fill, and errors caused by material proportion or material level changes are automatically tracked and corrected.
Counting & memory — the system counts filled units and memorizes parameters for repeat runs; the cleaning function clears residual material.
Sealing — the clean filling mouth makes the bag easy to seal; the operator moves to the next container.
