2026<\/p>\n\n    <p class=\"sa-lede\">Cast and extruded acrylic are both PMMA. They are not the same sheet. Cast is the usual choice for a polished edge, a solvent joint, and a face the customer looks at. Extruded is the usual cost choice for a thin back, a divider, or a part whose edge will not be polished. The nickname \u201cacrylic\u201d does not say which one you will get.<\/p>\n\n    <aside class=\"sa-takeaway\" aria-label=\"Key takeaways\">\n      <h2>Key takeaways<\/h2>\n      <ul>\n        <li>Specify cast or extruded. \u201cClear acrylic\u201d is not a route.<\/li>\n        <li>Cast is the safer default for visible polished panels and for solvent-bonded cases.<\/li>\n        <li>Extruded is reasonable for thin, non-show parts when edge polish is not the product.<\/li>\n        <li>Cast often varies more in thickness. Extruded is often more consistent. Exact tolerances belong to the standard and the mill, not to a blog number.<\/li>\n        <li>A cheaper quote that switched route is a different part.<\/li>\n        <li>Outdoor life and yellowing are grade questions on top of the route, not a property of the word \u201ccast.\u201d<\/li>\n      <\/ul>\n    <\/aside>\n\n    <nav class=\"sa-toc\" aria-label=\"On this page\">\n      <h2>On this page<\/h2>\n      <ol>\n        <li><a href=\"#answer\">The short answer<\/a><\/li>\n        <li><a href=\"#how\">How the two sheets are made<\/a><\/li>\n        <li><a href=\"#compare\">What changes for the buyer<\/a><\/li>\n        <li><a href=\"#choose\">Which route for which part<\/a><\/li>\n        <li><a href=\"#tolerance\">Thickness, without a fake number<\/a><\/li>\n        <li><a href=\"#specify\">What to write on the RFQ<\/a><\/li>\n        <li><a href=\"#faq\">FAQ<\/a><\/li>\n        <li><a href=\"#sources\">Sources<\/a><\/li>\n      <\/ol>\n    <\/nav>\n\n    <h2 id=\"answer\">The short answer<\/h2>\n\n    <div class=\"sa-def\">\n      <p><strong>Decision rule.<\/strong> If the edge faces the customer, or the joint is solvent-bonded and meant to disappear, start with cell-cast acrylic. If the part is thin, hidden, or a cost panel whose edge can stay frosted, extruded acrylic is often enough. On a box, the two routes can sit in the same product \u2014 cast on the show faces, extruded on a hidden back \u2014 if you say so.<\/p>\n    <\/div>\n\n    <h2 id=\"how\">How the two sheets are made<\/h2>\n\n    <p><strong>Cell-cast acrylic<\/strong> is poured as monomer between plates and cured. That is the sheet ISO 7823-1 covers. Display shops use it because it machines, polishes, and solvent-bonds in a predictable way. It is the usual sheet above the thin gauges, and the usual sheet when the edge is part of the look.<\/p>\n\n    <p><strong>Extruded acrylic<\/strong> is melted and pushed through a die. That is the sheet ISO 7823-2 covers. It is generally the lower-cost route and often the more consistent thickness. Laser-cut edges are typically frosted and need a separate polish if they face the customer. Heat bending and solvent joints are more sensitive than on cast.<\/p>\n\n    <p>Both are PMMA. A trade name \u2014 Plexiglass, Perspex, Lucite \u2014 does not tell you which process made the sheet in your quote.<\/p>\n\n    <h2 id=\"compare\">What changes for the buyer<\/h2>\n\n    <p>Directional. Grade and mill move the details. This is not a datasheet.<\/p>\n\n    <div class=\"sa-table-wrap\">\n      <table>\n        <caption>Cast vs extruded \u2014 what a display buyer feels<\/caption>\n        <thead>\n          <tr>\n            <th scope=\"col\"><\/th>\n            <th scope=\"col\">Cell-cast<\/th>\n            <th scope=\"col\">Extruded<\/th>\n          <\/tr>\n        <\/thead>\n        <tbody>\n          <tr>\n            <th scope=\"row\">Usual role<\/th>\n            <td>Show face, polished edge, bonded case<\/td>\n            <td>Back, divider, thin non-show panel<\/td>\n          <\/tr>\n          <tr>\n            <th scope=\"row\">Edge after laser or saw<\/th>\n            <td>Polishes cleanly; the usual cube edge<\/td>\n            <td>Often frosted; polish is extra and less even<\/td>\n          <\/tr>\n          <tr>\n            <th scope=\"row\">Solvent joint<\/th>\n            <td>The normal clear joint on a display box<\/td>\n            <td>Possible, more sensitive; not the default for a disappearing joint<\/td>\n          <\/tr>\n          <tr>\n            <th scope=\"row\">Thickness<\/th>\n            <td>Often wider variation across a sheet<\/td>\n            <td>Often tighter; helpful for slots and fits<\/td>\n          <\/tr>\n          <tr>\n            <th scope=\"row\">Heat bend<\/th>\n            <td>Works; practice differs from extruded<\/td>\n            <td>Common for simple bends; can whiten or bubble if the heat is wrong<\/td>\n          <\/tr>\n          <tr>\n            <th scope=\"row\">Relative sheet cost<\/th>\n            <td>Higher<\/td>\n            <td>Lower<\/td>\n          <\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n    <p>Do not copy a \u201c30 percent cheaper\u201d or a yellowing-year claim from a brochure into a specification. Cost depends on thickness, mill, and the stations after the sheet.

Say extruded so the quote is not priced as cast.<\/p>\n      <\/div>\n      <div class=\"sa-card\">\n        <h3>Slotted assembly<\/h3>\n        <p>Extruded\u2019s more consistent thickness can help the fit. If a slotted edge is also a camera edge, you are back to cast plus a polish.<\/p>\n      <\/div>\n      <div class=\"sa-card\">\n        <h3>Thick optical block or plinth<\/h3>\n        <p>Cast. Extruded sheet is not the usual route once the part is thick and the edge is finished.<\/p>\n      <\/div>\n    <\/div>\n\n    <p>Those constructions, in acrylic, are the usual retail set: <a href=\"https:\/\/www.sanait.com\/custom-acrylic-boxes\/\">boxes<\/a>, <a href=\"https:\/\/www.sanait.com\/custom-acrylic-trays\/\">trays<\/a>, and <a href=\"https:\/\/www.sanait.com\/\">display stands<\/a>.<\/p>\n\n    <h2 id=\"tolerance\">Thickness, without a fake number<\/h2>\n\n    <p>Cast sheet is cured between plates. Thickness can vary more across a sheet than extruded sheet of the same nominal gauge. Extruded sheet is generally more uniform, which is why it is preferred for press fits and interlocking slots.<\/p>\n\n    <p>The allowed variation is in ISO 7823-1 for cast and ISO 7823-2 for extruded, and then in the mill\u2019s own tolerance for that grade. Quote the standard or the mill sheet. Do not invent a plus-or-minus percent on a buying guide and treat it as universal.<\/p>\n\n    <p>Design joints with a fit allowance either way. A nominal 5 mm wall is a name. The mating part has to survive the real sheet.<\/p>\n\n    <h2 id=\"specify\">What to write on the RFQ<\/h2>\n\n    <ol>\n      <li>PMMA, then cast or extruded \u2014 per member if they differ.<\/li>\n      <li>Which edges are polished, and to what level.<\/li>\n      <li>Which joints are solvent-bonded.<\/li>\n      <li>Nominal thickness, and whether a fit depends on it.<\/li>\n      <li>Whether a named mill grade is required, or any cell-cast \/ any extruded is acceptable.<\/li>\n    <\/ol>\n\n    <p>A quote that does not state the route is not comparable to one that does. Ask before you award on price.<\/p>\n\n    <p>Sanait fabricates acrylic displays and will read a brief as needing a stated route. How a brief is taken is on the <a href=\"https:\/\/www.sanait.com\/faq\/\">FAQ<\/a>. Scope is on the <a href=\"https:\/\/www.sanait.com\/about-us\/\">about page<\/a>.<\/p>\n\n    <h2 id=\"faq\">FAQ<\/h2>\n\n    <div class=\"sa-faq\">\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">Is cast acrylic better than extruded?<\/h3>\n        <p class=\"sa-faq-a\">Better for a polished edge and a clear solvent joint. Not automatically better for a thin hidden panel, where extruded is often the correct and cheaper sheet.<\/p>\n      <\/div>\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">Can I solvent-bond extruded acrylic?<\/h3>\n        <p class=\"sa-faq-a\">Yes, with more care, and the joint is less forgiving than cast-to-cast. For a disappearing joint on a show box, specify cast.<\/p>\n      <\/div>\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">Why is cast more expensive?<\/h3>\n        <p class=\"sa-faq-a\">The sheet itself usually costs more, and the parts that need cast usually also need polish and joints. You are often paying for the route and the stations, not for a brand word.<\/p>\n      <\/div>\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">Does cast yellow less?<\/h3>\n        <p class=\"sa-faq-a\">Route is not a weathering guarantee. Grade and exposure decide. Ask for the grade if the face sits in a window. Do not treat \u201ccast\u201d as a UV specification.<\/p>\n      <\/div>\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">Can one box use both?<\/h3>\n        <p class=\"sa-faq-a\">Yes, if you assign them: cast on show faces and joints, extruded on a hidden back or divider. Write it. A silent mix is how two \u201cacrylic boxes\u201d become different products.<\/p>\n      <\/div>\n      <div class=\"sa-faq-item\">\n        <h3 class=\"sa-faq-q\">What if the quote only says acrylic?<\/h3>\n        <p class=\"sa-faq-a\">Ask cast or extruded before you compare price. The missing word is the specification.<\/p>\n      <\/div>\n    <\/div>\n\n    <div class=\"sa-author\" id=\"author\">\n      <h2>About the author<\/h2>\n      <p class=\"sa-author-name\">David Deng<\/p>\n      <p class=\"sa-author-role\">R&#038;D manager at Sanait. 10+ years in acrylic fabrication; 2,000+ custom acrylic projects shipped across 20+ countries.<\/p>\n      <p>Sanait Co., Ltd. builds custom acrylic displays, boxes, and trays in Dongguan.
