Most processors either bought pre-colored and specially formulated resins for each product they produced, or they measured out color concentrate and additives using a scoop and a scale. Drum tumblers were often used to tumble-mix the additive blend with virgin and regrind materials once it was manually created. Inaccuracies and inefficiencies were significant, but there was no alternative.<\/p><p>For simple mixing of regrind back into virgin material, processors attached proportioning valves to vacuum loaders and receivers to layer materials during loading in very rough proportions. As the industry grew and volumes increased, processors demanded equipment that would blend and mix ingredients in larger quantities with much greater accuracy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-952e660 elementor-widget elementor-widget-heading\" data-id=\"952e660\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The Volumetric Era<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9eac0ce elementor-widget elementor-widget-text-editor\" data-id=\"9eac0ce\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img decoding=\"async\" class=\" wp-image-4845 alignleft\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/generic-volumetric-blender-auger-feeder-1.png\" alt=\"\" width=\"252\" height=\"232\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/generic-volumetric-blender-auger-feeder-1.png 336w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/generic-volumetric-blender-auger-feeder-1-300x277.png 300w\" sizes=\"(max-width: 252px) 100vw, 252px\" \/>This need resulted in the development of the volumetric blender. In this device, materials were dispensed from their respective bins based on time, presuming a certain consistent flow rate for each ingredient. Screw augers ran beneath each material bin to move materials into a mixing chamber where all ingredients were combined. The augers were either different diameters, ran at different speeds, or ran for different durations to achieve the approximate desired proportional mix.<\/p><p>The most common customer complaint was inaccuracy of the blend, largely because of the inaccuracy of the main material quantities and the natural &#8220;pulsing&#8221; action of the augers. Metering accuracy was dependent upon the position of each auger when metering started and stopped, and undesirable vibration common with injection molding exaggerated the errors. Accurate and regular calibration of metering devices was required, but the calibration of volumetric devices is cumbersome, time-consuming, and fraught with the risk of human error.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-101b5b0 elementor-widget elementor-widget-heading\" data-id=\"101b5b0\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The Gravimetric Revolution<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-811dbc9 elementor-widget elementor-widget-text-editor\" data-id=\"811dbc9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4826 alignright\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-wsb-100.png\" alt=\"\" width=\"252\" height=\"232\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-wsb-100.png 336w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-wsb-100-300x277.png 300w\" sizes=\"(max-width: 252px) 100vw, 252px\" \/>In the higher material consumption world of continuous extrusion, solutions to these issues emerged with &#8220;loss-in-weight&#8221; gravimetric systems. In their original forms, these systems included supply bins for each material ingredient that were suspended on load cells so their weight could be individually monitored as they metered out each ingredient. These systems were complex and costly, but they were typical for extrusion lines capable of running high volumes for long, uninterrupted periods.<\/p><p>Meanwhile, alternate methods utilizing a &#8220;gain-in-weight&#8221; principle into a single hopper on load cells were being developed along with blender controls that could monitor load cell status yet remain unaffected by typical vibrations. The result was a range of simplified, cost-effective, easily cleaned, and rugged gravimetric blenders suitable for injection molding and virtually any process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-687e13a elementor-widget elementor-widget-heading\" data-id=\"687e13a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The Breakthrough That Changed Everything\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-94a9093 elementor-widget elementor-widget-text-editor\" data-id=\"94a9093\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5038 size-medium alignleft\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/02\/vertical-valves-241x300.png\" alt=\"\" width=\"241\" height=\"300\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/02\/vertical-valves-241x300.png 241w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/02\/vertical-valves.png 433w\" sizes=\"(max-width: 241px) 100vw, 241px\" \/>In the late 1980s, the plastics industry experienced a fundamental shift in blending technology. Processors didn&#8217;t need simpler volumetric feeders\u2014they needed affordable gravimetric precision.<\/p><p>At the time, gravimetric systems existed but were prohibitively expensive, complex machines typically 6 by 6 feet and 8 feet high, with four hoppers and elaborate auger systems feeding a central chamber. Each ingredient required its own set of load cells, making these systems practical only for the highest-volume continuous extrusion operations. Injection molders, who faced constant vibration and needed frequent material changes, had no access to this level of precision.<\/p><p>The solution came through a revolutionary approach: gain-in-weight batch blending using a single set of load cells on a common weigh chamber. Instead of complex calibration procedures, the system weighed each ingredient as it was dispensed\u2014making it self-correcting. Instead of being sensitive to vibration, sophisticated control algorithms filtered out interference while maintaining accuracy. The result was a compact, affordable, machine-mountable system that continuously self-corrects to deliver \u00b10.1% accuracy over multiple batches without calibration.<\/p><p>This breakthrough made gravimetric precision accessible to processors of all sizes. Today, these compact systems represent the industry standard for accurate, reliable blending across injection molding, extrusion, and blow molding operations worldwide.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-831cb34 elementor-widget elementor-widget-heading\" data-id=\"831cb34\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The Impact<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ea030ee elementor-widget elementor-widget-text-editor\" data-id=\"ea030ee\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4828 alignright\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-machine-mount-300x280.png\" alt=\"\" width=\"325\" height=\"303\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-machine-mount-300x280.png 300w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/novatec-maguire-weigh-scale-blender-machine-mount.png 515w\" sizes=\"(max-width: 325px) 100vw, 325px\" \/>The affordability and ease of use of this new &#8220;weigh scale&#8221; blender caused gravimetric blending to expand rapidly.

Like any recipe, the correct ingredients must be measured carefully and mixed properly. If they&#8217;re not, the end result won&#8217;t be what&#8217;s expected\u2026even if you process it exactly right.<\/p><p>Here are the most common issues that frequently stem directly from improper blending techniques.<\/p><ul><li><strong>Substandard Product Quality<\/strong><br \/>Uncontrolled use of regrind in the process is often traced to product performance failures. Regrind, if used at a higher level than prescribed by the material or product engineer, can result in premature product breakage and other performance issues. <br \/>Often, product testing creates a spike\u2026tested products are returned to the granulator at one time and inadvertently end up overloading the regrind content of the product. The controlled introduction of regrind into the process cannot be left to chance or the inaccuracies of sub-standard mixing devices like proportioning valves or volumetric dosing devices. Critical quality products require critical blending equipment.<\/li><li><strong>Inconsistent Color<\/strong><br \/>Lack of color concentrate or poor mixing are typical culprits when colors are not consistent in plastic products. Inaccurate blending practices are usually to blame when colorant is not sufficiently introduced or blended. Many processors compensate for this possibility by &#8220;overdosing&#8221; color into the mix to ensure it&#8217;s amply distributed during processing. But that leads to runaway colorant costs. The best solution is to use automated equipment that meters colorant by weight and provides ample mixing prior to processing. These devices are designed to halt production if proper coloring is not possible due to a blockage or lack of material, and typically save thousands of dollars over time in colorant costs.<\/li><li><strong>Runaway Additive Costs<\/strong><br \/>Color concentrate and other additives, especially if custom compounded, can represent a significant expense if their use is not highly controlled. It&#8217;s common practice to &#8220;overdose&#8221; to assure an adequate color or property when lower-tech methods are used to introduce additives to the process. Overdosing is a very expensive waste of money and lacks the cost control essential to cost-effective molding or extruding. The use of an automated blender that meters precious additives consistently and then checks and corrects each batch by weight is key to keeping costs under control.<\/li><li><strong>Excessive Labor Costs<\/strong><br \/>Incorrect production of parts not only creates waste from rejected parts, but also the labor to deal with them. In addition, sub-standard mixing and blending equipment that requires frequent calibration and checking to assure consistent operation consumes too many labor hours while also introducing the element of human error. Consistency and lack of human interaction are best achieved by automated blending equipment that does not require calibration by using weight readings for every dosing.<\/li><li><strong>Material Inventory Nightmares<\/strong><br \/>Processors who purchase pre-compounded materials for every color and formulation they run face enormous inventory challenges. Each unique compound must be stored, tracked, and managed. If specifications change or a product is discontinued, you&#8217;re left with unusable material. This ties up cash flow and warehouse space while increasing the risk of using the wrong material in production.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7a87680 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"7a87680\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-61e0417 elementor-widget elementor-widget-heading\" data-id=\"61e0417\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">\nYour Blending Options: From Worst to Best\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-281c23f elementor-widget elementor-widget-image\" data-id=\"281c23f\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"803\" height=\"494\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/plastics-blending-progression-scoop-to-gravimetric.png\" class=\"attachment-large size-large wp-image-4855\" alt=\"\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/plastics-blending-progression-scoop-to-gravimetric.png 803w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/plastics-blending-progression-scoop-to-gravimetric-300x185.png 300w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/plastics-blending-progression-scoop-to-gravimetric-768x472.png 768w\" sizes=\"(max-width: 803px) 100vw, 803px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ea68db9 elementor-widget elementor-widget-text-editor\" data-id=\"ea68db9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Every processor has a choice in how to feed material to their process.

This is fundamentally different from continuous &#8220;loss-in-weight&#8221; systems that require a separate set of load cells for each ingredient bin.<\/p><p>As each material is metered and deposited into the weighing chamber, its specific weight gain is sensed and calculated as part of the desired blend. Any inaccuracy is noted and the control modifies metering accordingly on the next metering cycle. Several metering cycles are typically included in each batch of blended material, so as time goes on, the blender actually becomes more accurate and self-corrects continuously throughout its operation. This continuous self-correction typically achieves specification within approximately ten batches as the system adjusts for material variations.<\/p><p>The materials are then discharged from the weigh bin into a mixing chamber, which is integrated into the system. There, the blend is homogenized continuously until use or to a specification set by the processor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f4c3113 elementor-widget elementor-widget-heading\" data-id=\"f4c3113\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Metering Devices for Different Materials<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dff1793 elementor-widget elementor-widget-text-editor\" data-id=\"dff1793\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The batch blender provides a metering method for all materials in the blend, but unlike continuous blenders, the batch system uses metering devices better suited to the nature and volume of each ingredient.

In today&#8217;s competitive world, simply hoping that humans always follow procedures is not good enough. The use of true gravimetric equipment that will not only flawlessly perform highly accurate blending functions day in and day out, but also keep track of all material consumption is, in itself, payback for the expenditure. Since every material\u2014virgin, regrind, additives\u2014is actually weighed as part of the gravimetric blending process, reports may be readily summoned that accurately track consumption and can even alert you to re-order points for your supplies.

Controlling the level of regrind in a critical component can affect not only color matching but also the strength or weakness of a part. The common mistake of overdosing color additive to assure adequate color matching not only creates unnecessary expense but can also affect the properties of the product. Wire manufacturers must be concerned about &#8220;sparking out&#8221; of their wire products from excess colorant. Many processors realize that excess color can change the magnetic or electrical properties of their products. The ability to show customers reports on actual material versus additive content by weight in every product is very compelling.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c8492a0 elementor-widget elementor-widget-heading\" data-id=\"c8492a0\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Staying Flexible for Varying Feedstock Supplies<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-17fa906 elementor-widget elementor-widget-text-editor\" data-id=\"17fa906\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4881 alignleft\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/material-consumption-tracking-and-documentation-icon.png\" alt=\"\" width=\"268\" height=\"247\" srcset=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/material-consumption-tracking-and-documentation-icon.png 336w, https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/01\/material-consumption-tracking-and-documentation-icon-300x277.png 300w\" sizes=\"(max-width: 268px) 100vw, 268px\" \/>In the still very new reclaim product marketplace, a consistent supply of feedstock cannot be assured and processors must be ready to make rapid formulaic changes to accommodate what is available or no longer available. Varying supplies of wood flour, regrind, flake, and other recycled content are often seized upon to be included in products that boast recycle content. Processors need equipment that can be quickly re-aligned for a changing feedstock supply. Gravimetric blenders are typically huge problem solvers for this class of processor with their ability to not only permit simple entry of new recipes but also retain past recipes that can be called upon to be run again.

equipment isn&#8217;t just about buying machinery\u2026it&#8217;s about taking control of one of your largest operating expenses while simultaneously improving product quality and operational efficiency.<\/p><p>If you&#8217;re still using manual methods, proportioning valves, or volumetric systems, you&#8217;re leaving money on the table with every production run. The question isn&#8217;t whether precision blending will pay for itself, but how quickly.<\/p><p>We talk to processors like you every single day about specific blending challenges\u2026whether it&#8217;s getting regrind consumption under control, eliminating color streaking, or just figuring out why additive costs keep climbing. Every operation is different, and we&#8217;d love to understand yours.<\/p><p>Give us a holler or reach out on the form below to start a conversation about your blending needs. Whether you&#8217;re running a single machine or a multi-line facility, processing commodity resins or specialty compounds, we&#8217;ll help you figure out the right solution for your operation.<\/p><p>No sales pitch. No pressure.
