A casting is different:<\/p>\n<ul>\n<li><strong>Irregular shape.<\/strong> Ports and flanges stick out, so the casting rests on a few high points instead of a face.<\/li>\n<li><strong>Offset centre of gravity.<\/strong> Wall thickness varies, so the mass is rarely in the middle of the outline.<\/li>\n<li><strong>Faces to protect.<\/strong> Machined flanges and sealing faces must not carry load or be scratched.<\/li>\n<\/ul>\n<p>The fixture turns an awkward shape into a stable one: defined support points on rough cast surfaces, machined faces kept free, and the part held in a known position relative to the pivot. That is why the cradle carries a contoured bolster, not a flat plate.<\/p>\n<h2 id=\"cog\">Centre of gravity during a 90\u00b0 turn<\/h2>\n<p>On an L-frame upender the load first rests on the base platen. As the frame turns, the weight moves progressively onto the back platen; halfway through the turn both platens share it.<\/p>\n<p>Two rules follow:<\/p>\n<ol>\n<li><strong>Keep the centre of gravity inside the support area at every angle.<\/strong> If it passes outside the contact points, the casting tips within the fixture instead of turning with it.<\/li>\n<li><strong>Keep the centre of gravity close to the pivot.<\/strong> The drive must resist the load moment, which equals load weight \u00d7 horizontal distance from the pivot to the centre of gravity. A fixture that sets the casting deeper into the cradle reduces that distance and smooths the turn.<\/li>\n<\/ol>\n<p>We take the casting drawing, find the centre of gravity, and check its path through the full 90\u00b0 before we fix the fixture geometry.<\/p>\n<h2 id=\"frame-sizing\">Sizing the frame: load class and turning time<\/h2>\n<p>Our standard 90\u00b0 mould upender range gives a starting point.

This equipment class uses about 15 L of hydraulic oil, manual plus remote control, and 220 V \/ 380 V supply options [manufacturer rating]; the family spans 5\u201340 t plus 180\u00b0 systems.<\/p>\n<p>Table size and machine size are designed per load, so the fixture and the platens are drawn around your part, not chosen from a catalogue.<\/p>\n<h2 id=\"fixture-design\">How we design the fixture<\/h2>\n<p>For a casting fixture we work from four inputs:<\/p>\n<ul>\n<li><strong>Casting drawing with weight and centre of gravity<\/strong>, or a 3D model we can weigh in CAD.<\/li>\n<li><strong>Support faces<\/strong>: rough cast surfaces the fixture may touch, and faces it must not touch.<\/li>\n<li><strong>Orientation before and after the turn<\/strong>: how the casting arrives and how it must be presented for machining, assembly or inspection.<\/li>\n<li><strong>Part family<\/strong>: if several castings share one upender, we design a base fixture with exchangeable inserts.<\/li>\n<\/ul>\n<p>The finished fixture is welded steel, painted, and fitted to the cradle. Where a part family has several sizes we check every size against the centre-of-gravity rule, not just the heaviest.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a casting upender<\/h2>\n<ul>\n<li>Heaviest casting and its centre of gravity, with the drawing or model.<\/li>\n<li>Largest outline: length, width and height in the starting position.<\/li>\n<li>Faces that may carry load and faces that must stay free.<\/li>\n<li>Turning angle needed: 90\u00b0 or 180\u00b0 (for a full turnover see our <a href=\"https:\/\/www.fhopepack.com\/videos\/rotatable-180-degree-automatic-multipurpose-tilter\/\">180\u00b0 load inverter<\/a>).<\/li>\n<li>How the casting is loaded and unloaded: crane, forklift or a <a href=\"https:\/\/www.fhopepack.com\/videos\/trolley-car-for-steel-coil-with-track\/\">rail transfer cart<\/a>.<\/li>\n<li>Cycles per shift, which sets the drive duty and turning time.<\/li>\n<li>Floor space, foundation and supply voltage at the installation point.<\/li>\n<\/ul>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the emergency-stop arrangement.<\/p>\n<p>The turning zone is the hazard. Nobody stands inside the sweep of the cradle while it moves, and loading or unloading happens only with the cradle at rest in its end position.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why does the fixture matter more for castings than for moulds?\nA: A casting has an irregular shape and an offset centre of gravity. The fixture gives it defined support points and keeps the centre of gravity inside the support area through the full 90\u00b0.<\/p>\n<p>Q: How long does a 90\u00b0 turn take?\nA: Our standard 90\u00b0 frames list 60\u201390 s for the 10 t frame and 70\u201390 s for the 20 t and 30 t frames.<\/p>\n<p>Q: Our casting weighs 15 t. Which frame do we need?\nA: It depends on size and centre of gravity, not weight alone. We would size yours from the drawing and may build it on a heavier frame if the part is bulky.<\/p>\n<p>Q: How does the load move across the platens during the turn?\nA: The casting starts fully on the base platen. As the cradle turns 90\u00b0, the load shifts progressively to the back platen; halfway through, both platens share it.<\/p>\n<p>Q: Do we need a 90\u00b0 or a 180\u00b0 upender?\nA: 90\u00b0 stands a part up or lays it down. 180\u00b0 turns it over to reach the underside \u2014 for that, our range includes a C-type 180\u00b0 sheet upender rated 15 t [manufacturer rating].<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We size a casting upender in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with the casting drawing, weight, centre of gravity and the turning angle you need, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, including the frame, the drive and a fixture concept drawn around your casting.<\/li>\n<li><strong>Book a site survey<\/strong> so we confirm the loading method, the floor and the space for the cradle sweep.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/mold-tipper-and-upender\/\">Industrial Mold Tipper and Upender: Heavy Mold Handling<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/die-mould-upender-and-tilter\/\">Die Mould Upender and Tilter<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/the-roi-of-safety-why-90-degree-mold-upenders-are-replacing-overhead-cranes-in-industrial-toolrooms\/\">The ROI of Safety: 90-Degree Mold Upenders Instead of Crane Flipping<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/mold-upender\/\">Mold upender<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Comparable machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=UxuF7bEsI2I\">the video on YouTube<\/a><\/li>\n<li>Frame range, loading, power, turning time, machine weight: <a href=\"https:\/\/www.fhopepack.com\/mold-upender\/\">Mold upender<\/a><\/li>\n<li>Hydraulic oil, control and power options: <a href=\"https:\/\/www.fhopepack.com\/mold-upender\/90-Degree-Mold-Upender-5T.html\">90 Degree Mold Upender 5T<\/a><\/li>\n<li>180\u00b0 sheet inversion comparison: <a href=\"https:\/\/www.fhopepack.com\/Mechanical\/steel-sheet-upender.html\">Steel sheet upender<\/a><\/li>\n<li>Machine Safety Design Standards: ISO 12100:2010; <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<li>Proposal timing: approved house CTA (proposal within 48 hours)<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary An L-frame upender with a shaped fixture turns heavy cast housings from flat to upright.
