Net Weight Fillers

Net Weight Filling Equipment

Net weight filling equipment is the only filling method that actually weighs product prior to dispensing into the packaging container. Net weight fillers can be utilized for a wide array of purposes including counting, filling a wide array of regular and irregular sized products, and for dry or slightly moist products. Net weight filling systems can also be set up in several formats for very gentle handling of product with the use of mulitiple vibratory feed trays also known as cascading feeders (very popular for chips and other delicate and hard to feed products).  Examples of net weight filling applications include:
Dry Products Counting Applications
Heavy Powders Rice Beans Nuts Cereals Granulated Products Candy Hardware Parts Plastic Parts Tablet Counting Capsule Counting Candies

All of these net weight fillers can be used semi-automatically, or integrated into automatic lines or baggers. These systems are pre-programed to be used either way. All of the systems are graduated to 1 gram readout.  the controller featrues a self calibration mode, and easy to use learning mode that automatically optimizes all settings.  Store up to 99 products into memory for easy recall. Four models to choose from.

S-4 Weigh Filler Packaging Machine

The S-4 Net weight filler is a very affordable machine built right here in the USA starting at only $6,150 for a complete net weight filler including powder coated stand, 250 cu.in. weigh bucket, 3.5 cu.ft. supply hopper, and small discharge funnel. (Filling spouts, if required, are $150 each.  Options are available for larger sizes, including flap closure for fine regulation of the dribble feed. Larger capacities and other options are available at slightly higher cost.

  • Controller range up to 10lbs.

  • Supply Hopper cup, 3.5 cu.ft.

  • Powder-coated chassis. Stainless steel optional

  • All product surfaces stainless steel

  • Automatic tare adjustment

  • Self-adjusting bulk & dribble speed control

  • 600-800 fills/hour

The Model S-4 net weight filler shares many of the same basic characteristics of the S-5. By using a weigh hopper that drops the entire weighment at once and an electro magnetic vibrator, the S-4 can be up to twice as fast as the S-5, and have greater accuracy at higher speeds and lower net weights.

Example: To run a relatively free-flowing product into a 1 lb. package, the product is loaded into the hopper, and the total weight is set at 1 lb. After starting the first fill cycle with the foot pedal, the controller will automatically switch into “learn mode” for the first cycle. During this time the controller tests the flow characteristics of the product and decides the best speeds and duration for bulk and dribble. The controller will automatically change the vibratory feed from bulk to dribble and stop the scale at 1 lb. The bag is removed and sealed. Each successive container is now filled by placing it under the funnel and depressing the foot pedal.

S-5 Bulk Net Weight Filler for Bags and Boxes up to 75 pounds

The S-5 Bulk Weight filler works a little differently than the other net weight fillers on this page.  It is designed for filling boxes or bags up to 75 pounds and starts each fill cycle by taring out the box before starting product feed.  In this case the box sits on top of the scale where the box is acting as the weigh bucket directly.

  • Bulk filling for weights of up to 75lbs.

  • Self-adjusting controller

  • Reads out to  .01 lbs.

  • Controller range up to 75lbs., 3.5cu.ft. hopper

  • All product surfaces Stainless Steel

  • Footprint 4.6 sq.ft., 67″ high

  • 120V 60Hz (wall outlet); 240V 50Hz option

  • Handles any dry bulk material from powders to large parts

  • Used with any bag or rigid container

  • Automatic tare adjustment

  • Self-adjusting bulk & dribble speed control

  • 300-400 fills/hour

The very accurate and easy to operate Model S-5 semi-automatic scale has automatic tare, automatic feed and speed controls for both bulk and dribble feed rates, and automatic set points. The product flow from the hopper to the feed pan can also be controlled by an adjustable slide gate.

Example: To run a relatively free-flowing product into a 10 lb. package, the product is loaded into the hopper, and the target weight is set at 10 lb. The package is placed on top of the scale, and the table is adjusted (up/down) so that the funnel is inside the bag in order to keep the bag “standing” when empty. After starting the first fill cycle with the foot pedal, the controller will automatically switch into “learn mode” for the first cycle. During this time the controller tests the flow characteristics of the product and decides the best speeds and duration for bulk and dribble. The controller will automatically change the vibratory feed from bulk to dribble and stop the scale at 10 lb. The bag is removed and sealed. Each successive container is now filled by placing it under the funnel and depressing the foot pedal.

All product contact surfaces are stainless steel and easily disassembled: two screw knobs hold the funnel, two screw knobs hold the vibratory feed, four nuts hold the hopper. If needed, the scale and control panel can be removed from the table, and the table can be removed from the frame.

S-6 Cascading Style Net Weight Filler

The S-6 net weight filler is a great machine for applications that require more accuracy for weighing or counting. The second pan is normally set up to a faster speed than the first so that a thinner layer (or more spacing on parts) is achieved which allows the dribble feed to be more accurate.  Adding a dribble feed gate to the system can create even more accuracy when needed. This system is also ideal for hard to feed products like chips.

  • Cascading feed pans

  • Self-adjusting controller

  • Reads out to 1 gram or .001 lbs.

  • Controller range up to 10 lbs.

  • Supply hopper 3.5 cu.ft.

  • All product surfaces Stainless Steel

  • Powder-coated chassis. Stainless steel optional

  • Footprint 7.5 sq.ft., 74.5″ high

  • 120V, 60Hz (wall outlet), 240V, 50Hz option

  • Handles any dry bulk material from powders to large parts

  • Compatible with all bags, rigid containers, and bagging machines

  • Automatic tare adjustment

  • Self-adjusting bulk & dribble speed control

  • 600-800 fills/hour

The model S-6 cascading weigh filler is designed to fill harder to run products such as crackers, chips and other non-free-flowing products. A very accurate and easy to use control system monitors the product depth in the lower pan allowing for consistent filling. The S-6 utilizes many of the same systems found on our S-4, including the Logical Controller II, for reliable, hassle free operation.

S-7 Two Head Net Weight Filling System

The two head S-7 weigh filler can be used in three separate modes: Simultaneous Mode where both scales fill and dump at the same time to double weighing speeds; Individual Mode where the scales operate independently and alternate dumps for another way to double up speeds, great for automation to 25 fills per minute; or Mix Mode (requires divided hopper option) where two different products with different, or the same, weights can dump together to mix the components into a common package.

  • Two lanes for twice the speed
  • Self-adjusting controller
  • Reads out to 1 gram or .001 lbs.
  • Controller range up to 10 lbs.
  • 5.1 cu.ft. supply hopper
  • All product surfaces Stainless Steel
  • Footprint 7.5 sq.ft., 68″ high
  • 120V 60Hz (wall outlet); 240V 50Hz option
  • Handles any dry bulk material from powders to large parts
  • Compatible with all bags, rigid containers, and bagging machines
  • Automatic tare adjustment
  • Self-adjusting bulk & dribble speed control
  • 600-1200 fills/hour

The model S-7 two lane net weight filler shares many of the same basic characteristics of the S-4. A very accurate and easy to use controller allows for three different modes of operation. In simultaneous dump the machine fills both weigh hoppers at the same time, allowing for twice as much product flow as our S-4. In individual dump the machine dumps whichever weigh hopper is at weight. This gives twice the speed of our S-4 weigh-fill machine. Finally the model S-7 net weight filler can mix products. The controller can be set to weigh two completely different products at different weights to easily mix products into a container.
