By synchronizing bundle sizing and material consumption with a PLC\u2011controlled buffer conveyor, they cut shift waste by 40%, eliminated manual rework, and consistently delivered 8 tons per 12\u2011hour shift with half the operator attention.<\/strong> This case study demonstrates how a modest investment in coordination logic can solve throughput bottlenecks without buying faster machines.<\/p>\n<h2>\ud83d\udee0\ufe0f Client Background<\/h2>\n<iframe width=\"100%\" height=\"420\" src=\"https:\/\/www.youtube.com\/embed\/c-qsBbNIucQ?rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<p><strong>Alfania Company produces custom aluminum sections for construction and automotive markets. Operating two 12\u2011hour shifts, they cast billets, extrude profiles (cross\u2011sections from 20\u00d720 mm to 120\u00d7120 mm), and deliver surface\u2011protected bundles nationwide.<\/strong> Their packaging line used two independent machines \u2013 a tape applicator for surface protection and a stretch wrapper for bundling \u2013 but the machines were never designed to work together. Each shift packed 8 tons of aluminum, consuming <strong>3.5 rolls of PE stretch film per ton<\/strong> (each roll 4.3 kg, 200 m) and <strong>18 rolls of surface protection tape per ton<\/strong> (each roll 250 m). That translates to 5,600 m of film and 36,000 m of tape per shift \u2013 yet the real bottleneck was not individual machine speed, but the lack of coordination between them.<\/p>\n<h2>\ud83c\udfd7\ufe0f Challenge<\/h2>\n<p><strong>The core problem was a cycle\u2011time mismatch: the tape applicator could tape 300 profiles per ton in bursts, but the wrapping machine required a steady, pre\u2011taped input, causing 2 hours of manual bundle relocation and wrapper restarts every shift.<\/strong> The tape applicator ran at about 12 m\/min tape feed, while the stretch wrapper unwound film at roughly 8 m\/min. During the first half of the shift, the taper produced bundles faster than the wrapper could consume them, piling up inventory. Later, the taper would fall behind, starving the wrapper. Operators spent 2 hours per shift manually moving bundles and restarting the wrapper \u2013 direct labor cost of $120\/shift (based on an average operator wage rate). Additionally, common profile shapes (L, T, U) required different tape tension and film overlap settings, which neither machine could adjust automatically. Alfania\u2019s target was 8 tons per 12\u2011hour shift, but actual output averaged only 6.2 tons due to these coordination losses.<\/p>\n<p><em>Note: All numerical values in this case study are based on Alfania\u2019s specific operation and are provided for illustrative purposes. Actual results may vary. Machine speeds and material consumption are approximate and should be verified with your equipment supplier.<\/em><\/p>\n<h2>\ud83d\udcc8 Solution Design<\/h2>\n<p><strong>The solution was a coordinated bundle\u2011sizing logic that made the tape applicator and stretch wrapper share the same pace, using a buffer conveyor and a common PLC controller to enforce a six\u2011minute beat cycle.<\/strong> The recommended configuration:<\/p>\n<ul>\n<li>\n<p><strong>Tape applicator<\/strong> \u2013 an automatic profile\u2011taping machine (model from <a href=\"https:\/\/www.fhopepack.com\/Aluminum\/Automatic-profile-tapping-machine.html\">Fhope<\/a>, approximate specifications) that adjusts tape length per profile cross\u2011section. For an average of 300 profiles per ton, each profile requires about 15 m of tape (calculated from 18 rolls \u00d7 250 m \u00f7 300 profiles). The machine must hold a buffer of 50 profiles (~1\/6 ton) to absorb speed variation.<\/p>\n<\/li>\n<li>\n<p><strong>Stretch wrapper<\/strong> \u2013 a sub\u2011bundle wrapping machine (model from <a href=\"https:\/\/www.fhopepack.com\/Aluminum\/sub-bundle-wrapping.html\">Fhope<\/a>) that uses PE stretch film (3.5 rolls\/ton) with an overlap ratio of approximately 50% to ensure full surface coverage at a line speed of 8 m\/min.<\/p>\n<\/li>\n<li>\n<p><strong>Coordination rule<\/strong>: Both machines cycle on a six\u2011minute beat. The taper produces one bundle (\u2248 50 profiles, about 167 kg) in 3 minutes; the wrapper consumes it in 3 minutes, with a two\u2011bundle buffer between them. This eliminates starvation and overflow.<\/p>\n<\/li>\n<\/ul>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Tape Applicator<\/th>\n<th>Stretch Wrapper<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Throughput<\/td>\n<td>300 profiles\/ton (18 rolls tape)<\/td>\n<td>3.5 rolls film\/ton (700 m)<\/td>\n<\/tr>\n<tr>\n<td>Line speed<\/td>\n<td>12 m\/min (tape feed)<\/td>\n<td>8 m\/min (film unwinding)<\/td>\n<\/tr>\n<tr>\n<td>Bundle size<\/td>\n<td>L \u00d7 W \u00d7 H per your profile dimensions<\/td>\n<td>Same bundle dimensions<\/td>\n<\/tr>\n<tr>\n<td>Material<\/td>\n<td>Surface protection tape, 250 m\/roll<\/td>\n<td>PE stretch film, 200 m\/roll<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Glossary of technical terms:<\/em><\/p>\n<ul>\n<li>\n<p><strong>Pre\u2011stretch ratio<\/strong>: Amount the film is stretched before wrapping (e.g., 250% means 1 m of film covers 2.5 m of surface).

Alfania\u2019s profile file had sections from 20\u00d720 mm to 120\u00d7120 mm (typical for aluminum extrusions). Ensure the machine can handle your range; ask for a sample test.<\/p>\n<\/li>\n<li>\n<p>[ ] <strong>Material specifications<\/strong>: State packing material type (PE stretch film, paper, composite). For stretch film, specify pre\u2011stretch ratio (200\u2013300% typical) and overlap ratio (40\u201370%). For tape, specify roll width and core ID.<\/p>\n<\/li>\n<li>\n<p>[ ] <strong>Cycle time match<\/strong>: Calculate tape applicator speed (m\/min) vs. wrapper speed (m\/min). Use the 6\u2011minute beat rule as a starting point, but verify with actual profile geometry.<\/p>\n<\/li>\n<li>\n<p>[ ] <strong>Buffer capacity<\/strong>: Request a minimum 5\u2011bundle buffer (\u2248 250 kg for standard aluminum) between machines to absorb minor variations. Alfania\u2019s 2\u2011bundle buffer worked for them; your mileage may vary.<\/p>\n<\/li>\n<li>\n<p>[ ] <strong>PLC compatibility<\/strong>: Ask for open protocol (Modbus, Ethernet\/IP) to integrate with existing plant systems. Do not accept vendor\u2011locked control unless you have no alternatives.<\/p>\n<\/li>\n<\/ul>\n<blockquote>\n<p>\ud83d\udee1\ufe0f <strong>Compliance Note<\/strong>: This equipment is designed to meet ISO and CE requirements. Verify with the manufacturer.<\/p>\n<\/blockquote>\n<h2>\ud83d\udcc8 FAQ<\/h2>\n<p><strong>Q: Why did Alfania choose a coordinated system instead of two independent machines?<\/strong><br \/>\nA: Independent machines would have required extra operator headcount (one per machine) and still suffered from batch queuing. Coordination via PLC cut labor by 50% and eliminated the 2\u2011hour shift waste. The investment ($48,000 approximate) was justified by labor savings alone in under a year.<\/p>\n<p><strong>Q: What if my profile shapes are more complex than Alfania\u2019s (e.g., hollow sections, irregular contours)?<\/strong><br \/>\nA: Tape applicators use contact rollers that follow any external shape up to 200 mm diameter. For hollow sections, verify that the tape tension is low enough to avoid collapse (ask supplier for max tension in N). Wrapping machines handle irregular profiles by adjusting overlap ratio \u2013 typical range 40\u201370%. Request a sample test with your actual profile.<\/p>\n<p><strong>Q: Is it always better to use PE stretch film for aluminum protection?<\/strong><br \/>\nA: PE film is cost\u2011effective at approximately $2.40\/kg but may leave sticky residue on anodized surfaces. For sensitive finishes, use paper\u2011based wrapping (e.g., kraft paper + VCI). Alfania used film because their customers remove wrap immediately. Verify with your quality team \u2013 film savings may not be worth the risk of adhesive transfer.<\/p>\n<hr \/>\n<p><strong>Disclaimer:<\/strong> All numerical values in this case study (material consumption, costs, savings, payback periods, scratch reduction) are based on Alfania Company\u2019s specific operation as provided in the original context.
