If the throughput is wrong, the price is wrong \u2014 and the error is usually discovered after the order is placed.<\/p>\n<p>The arithmetic is not difficult. It is four relationships that most people in the industry know vaguely and few apply precisely:<\/p>\n<p><strong>Output = specific output \u00d7 screw speed.<\/strong> Specific output is kilograms per hour per rpm, and it depends on screw diameter, channel depth and the resin.<\/p>\n<p><strong>Line speed = output \u00f7 (cross-section \u00d7 density).<\/strong> This is what connects the extruder to the haul-off.<\/p>\n<p><strong>Draw-down = die opening \u00f7 finished dimension.<\/strong> This sets the relationship between the die and the product.<\/p>\n<p><strong>Yield = good product \u00f7 total output.<\/strong> Start-up, off-spec and trim all come out of the same barrel.<\/p>\n<div class=\"callout\">\n<p><strong>The number most often overestimated:<\/strong> specific output.

The PVC column is lower because the compound is more viscous and must run cooler, not because the screw is different.<\/p>\n<p>The relationship with screw speed is not perfectly linear. As speed rises, pressure flow back over the flights increases, and at very high speed the output curve flattens. Most screws are rated for a maximum speed that keeps them in the linear region, typically 60\u2013120 rpm for a 60 mm screw.<\/p>\n<h2 id=\"output\">Output and the die<\/h2>\n<p>The die affects output through its resistance. A restrictive die raises head pressure, which increases backflow, which reduces net output.

Below that, the extruder is oversized and running slowly, which causes long residence time and degradation. Above it, there is no headroom for a formulation change or a screen pack loading up.<\/p>\n<h2 id=\"linespeed\">From output to line speed<\/h2>\n<p>This is where the arithmetic becomes concrete.

A profile needs roughly 3\u20136 m of cooling per metre per minute of line speed, depending on wall thickness. At 6 m\/min that is 18\u201336 m of tank \u2014 which is why profile lines are long and why line speed is often limited by cooling rather than by the extruder.<\/p>\n<h2 id=\"drawdown\">Draw-down and the numbers it changes<\/h2>\n<p>Draw-down ratio is the die opening divided by the finished dimension. It affects output indirectly: a high draw-down lets a smaller die produce a bigger product, but it also thins the wall, which changes the mass per metre.<\/p>\n<table>\n<thead>\n<tr>\n<th>Product<\/th>\n<th>Typical draw-down<\/th>\n<th>Consequence<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Pipe<\/td>\n<td>1.0 \u2013 1.2<\/td>\n<td>Almost none; die sets the size<\/td>\n<\/tr>\n<tr>\n<td>Profiel<\/td>\n<td>1.05 \u2013 1.3<\/td>\n<td>Moderate; die slightly oversize<\/td>\n<\/tr>\n<tr>\n<td>Sheet<\/td>\n<td>1.0 \u2013 1.05<\/td>\n<td>Minimal; roll stack sets thickness<\/td>\n<\/tr>\n<tr>\n<td>Tube (thin wall)<\/td>\n<td>2.0 \u2013 5.0<\/td>\n<td>High; die gap much larger than wall<\/td>\n<\/tr>\n<tr>\n<td>Film (blown)<\/td>\n<td>20 \u2013 60<\/td>\n<td>Very high; orientation is the point<\/td>\n<\/tr>\n<tr>\n<td>Monofilament<\/td>\n<td>5 \u2013 15<\/td>\n<td>High; orientation for strength<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"tablecap\">Table 4 \u2014 Typical draw-down ratios. High draw-down amplifies any die error, which is why thin-wall tube needs a better die than pipe.<\/p>\n<p>Draw-down also affects the effective output per unit of product length. If you double the draw-down, the wall halves, the mass per metre halves, and the line speed doubles for the same output. That is the mechanism behind high-speed thin-wall tube lines.<\/p>\n<h2 id=\"yield\">Yield: the number that decides profitability<\/h2>\n<p>Output is what comes out of the die. Yield is what gets sold. The gap between them is start-up scrap, dimensional reject, surface reject and trim.<\/p>\n<table>\n<thead>\n<tr>\n<th>Loss category<\/th>\n<th>Typical range<\/th>\n<th>Where it comes from<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Start-up<\/td>\n<td>0.5 \u2013 3%<\/td>\n<td>Until dimensions and surface stabilise<\/td>\n<\/tr>\n<tr>\n<td>Dimensional reject<\/td>\n<td>1 \u2013 5%<\/td>\n<td>Drift, die wear, calibration problems<\/td>\n<\/tr>\n<tr>\n<td>Surface reject<\/td>\n<td>0.5 \u2013 3%<\/td>\n<td>Die lines, gels, marks<\/td>\n<\/tr>\n<tr>\n<td>Trim and cut waste<\/td>\n<td>1 \u2013 8%<\/td>\n<td>Edge trim on sheet, cut length allowance<\/td>\n<\/tr>\n<tr>\n<td>Changeover<\/td>\n<td>0.5 \u2013 2%<\/td>\n<td>Purge and re-stabilisation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"tablecap\">Table 5 \u2014 Where output is lost before it becomes saleable product.

The two numbers people most often get wrong are specific output (using a sales figure) and yield (forgetting it entirely).<\/p>\n<p>If the cooling tank on this line is only 20 m, the line cannot run at 6.55 m\/min \u2014 it is limited to about 4 m\/min, which means 80 kg\/h, which means the machine rate per kilogram rises by 65%. That is why cooling length is a commercial constraint and not just an engineering detail.<\/p>\n<div class=\"faq\">\n<h3>How do I calculate extrusion output?<\/h3>\n<p>Output = specific output \u00d7 screw speed. Specific output (kg\/h per rpm) comes from the screw geometry and the resin \u2014 roughly 3\u20134 kg\/h\/rpm for a 60 mm screw in PE, 2\u20132.8 in rigid PVC. For a first estimate, use the manufacturer's figure and reduce it 20\u201330% for the actual material.<\/p>\n<h3>Why is my line not reaching the rated output?<\/h3>\n<p>Usually one of three things: the die is more restrictive than the rating assumed, the cooling section is too short to run at that speed, or the material is more viscous than the one the rating was based on. Check head pressure first \u2014 if it is near the machine limit, the die is the constraint.<\/p>\n<h3>How do I convert output to line speed?<\/h3>\n<p>Divide output by mass per metre, then by 60 to get m\/min. Mass per metre is cross-section area times density. A 40 \u00d7 6 mm PVC profile at 1,400 kg\/m\u00b3 is 0.336 kg\/m, so 120 kg\/h gives 5.95 m\/min.<\/p>\n<h3>What is a normal yield for extrusion?<\/h3>\n<p>88\u201395% for a well-run profile line. Sheet lines are lower because of edge trim, sometimes 85\u201390%. Anything below 85% is worth investigating \u2014 the loss is usually in dimensional drift rather than in visible defects.<\/p>\n<h3>Does screw speed affect product quality?<\/h3>\n<p>Yes. Higher speed means higher shear, higher melt temperature and shorter residence time. Some resins benefit (better mixing), others degrade. Most screws are designed to run at 60\u201380% of maximum for the best balance of output and melt quality.<\/p>\n<h3>Why does draw-down matter for costing?<\/h3>\n<p>Because it changes mass per metre. Higher draw-down means a thinner wall, which means less material per metre, which means higher line speed for the same output. It also amplifies die errors, so there is a quality cost alongside the throughput gain.<\/p>\n<h3>How long does the cooling tank need to be?<\/h3>\n<p>Roughly 3\u20136 m of tank per m\/min of line speed, depending on wall thickness and resin. Thicker walls need the upper end. If the tank is too short, line speed is limited by cooling and the extruder runs below its capacity.<\/p>\n<h3>Should I size the extruder for the die or the die for the extruder?<\/h3>\n<p>Size the extruder so the die consumes 60\u201380% of its pressure capability at the design output. An oversized extruder running slowly gives long residence time and degradation; an undersized one cannot reach the output and runs at its pressure limit.<\/p>\n<\/div>\n<div class=\"cta\">\n<p class=\"cta-h\">Need a throughput or cost estimate for a profile?<\/p>\n<p>Send us the drawing, the resin and the annual volume. We will come back with the screw size, the line speed, the cooling length required and a price per kilogram at your yield.<\/p>\n<p><a class=\"btn\" href=\"https:\/\/uplastech.com\/nl\/oplossingen-voor-kunststofextrusie\/\">Talk to an extrusion engineer<\/a>\n<\/div>\n<div class=\"rel\">\n<h4>Continue reading<\/h4>\n<ul>\n<li><a href=\"https:\/\/uplastech.com\/nl\/extruder-screw-design\/\">Extruder Screw Design: Zones, Compression Ratio and Wear<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/nl\/melt-pump-screen-changer-pressure-stability\/\">Melt Pump and Screen Changer: Why Pressure Stability Beats Temperature<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/nl\/extrusion-tooling-cost\/\">Extrusion Tooling Cost: What a Profile Die Really Costs<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/nl\/plastic-sheet-extrusion-roll-stack\/\">Plastic Sheet Extrusion: Roll Stack and Thickness Control<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/nl\/plastic-pipe-extrusion-guide\/\">Plastic Pipe Extrusion: Materials, Standards and Sourcing<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The arithmetic every quotation depends on: specific output, drag flow, puller speed and the take-up ratio that decides whether you hit dimension at the quoted rate.<\/p>","protected":false},"author":1,"featured_media":7673,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"Extrusion Output Calculation: Throughput, Screw Speed and Li","_seopress_titles_desc":"The arithmetic every quotation depends on: specific output, drag flow, puller speed and the take-up ratio that decides whether you hit dimension at the quo","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"17","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"extrusion output calculation","footnotes":""},"categories":[17],"tags":[],"class_list":["post-7680","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-plastic-extrusion-process"],"meta_box":{"post-to-quiz_to":[]},"_links":{"self":[{"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/posts\/7680","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/comments?post=7680"}],"version-history":[{"count":0,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/posts\/7680\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/media\/7673"}],"wp:attachment":[{"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/media?parent=7680"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/categories?post=7680"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/uplastech.com\/nl\/wp-json\/wp\/v2\/tags?post=7680"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
