Best Graduated Mixing Cups for Epoxy Resin and Casting
Anyone who has poured a river table or cast a batch of coasters knows the truth about two-part resin: the mix is where projects are won or lost. The right epoxy resin mixing cups make that step repeatable instead of nerve-wracking. When your cup has clear, accurate volume graduations printed right on the wall, you stop guessing and start measuring. That is the difference between a glass-clear cure and a sticky, frustrating do-over.
At GL Enterprises, we have been injection molding graduated cups in Ogden, Utah since 1976. Our Quick Mix cups were built for precise two-part mixing, and while a lot of shops know them from the paint world, the resin and casting crowd has discovered the same thing: a well-marked cup takes the anxiety out of the ratio.
Why Accurate Graduations Matter for Resin
Most casting and coating epoxies are mixed by volume or by weight in a fixed ratio, commonly 1:1 or 2:1. If your measurement is off, the chemistry is off, and no amount of stirring fixes it. Under-measure the hardener and you get a soft, tacky surface that never fully sets. Over-measure it and you can get excess heat, bubbles, or a brittle finish.
Clear, printed graduations let you line up resin and hardener to the exact marks you need, every single time. Because the markings are pad-printed onto the cup wall, they stay put and stay legible even when the outside gets messy. You read the fill line at eye level, confirm your ratio, and pour with confidence. For a process where a few percent of error shows up as a flaw in the final piece, that reliability is worth a lot.
Matching Cup Sizes to Your Project
One of the most practical decisions is simply picking the right size cup for the job. Too big and small batches are hard to read accurately down at the bottom. Too small and you are mixing multiple rounds when you did not need to.
For small casts, tumblers, jewelry, and touch-up work, our 8oz and 16oz Quick Mix cups hit the sweet spot. They give you fine, readable graduations at the volumes those projects actually use, so a two-ounce pour is just as precise as a two-cup pour. As your work scales up, our 32oz and 40oz cups handle coasters, trays, and mid-size coatings, while the 80oz and 174oz cups are there for deep pours, tabletops, and production runs. Keeping a few sizes on the shelf means you always reach for a cup that fits the batch.
Disposable Convenience Without the Compromise
Cured epoxy does not clean out of a cup easily, and most resin workers do not want to try. The appeal of a rigid, disposable mixing cup is that you mix, pour, and set it aside. Leftover resin cures in the cup, and many crafters simply peel or pop it out later.
Our cups are durable polypropylene-style mixing cups, so they hold their shape while you stir vigorously and stay rigid when you pour, with no flimsy walls collapsing mid-pour. They are affordable enough to use once and reach for the next, which is exactly why buying them by the case makes sense for anyone mixing regularly. You get clean, consistent results without babysitting your glassware.
Made in the USA, Built to a Standard
Every Quick Mix cup is made in-house at our Utah facility, from injection molding to pad printing to packaging. That means we control the quality of the graduations you are trusting your ratio to. As a family-owned American manufacturer coming up on five decades, we would rather earn repeat customers with cups that measure true than cut corners you would notice later.
Whether you are a weekend caster or a professional fabricator running batches all week, the goal is the same: mix it right the first time.
