Agenda:  Why are you considering automation? What problems are you trying to solve? How and why automation can help Crunch the numbers and determine the ROI

We can’t get enough of the Zoku Classic Pop Molds. After trying 20 different popsicle molds of every shape, size, and material, this one stood out as our clear winner with a perfect score. Across the categories of design, ease of use, performance, and ease of cleaning, this mold was our favorite by far. It’s cute, durable, and highly user-friendly for the whole family.

The Zoku Classic Pop Molds are meant to be used time and time again for mess-free desserts. The vibrant green plastic mold is sturdy enough to keep it from tipping or slipping in your freezer and pouring any popsicle-ready base couldn’t be easier. We loved the reusable sticks and the fact that it comes with a fitted cover. Even better, it’s made up of individual molds in a holder, so removing only a single popsicle is a breeze. The sticks are drip-catchers, too, so they catch stray drops of melted ice pop to help keep hands, clothes, or floors free of melted-sicle. During testing, we also appreciated the fill line that told us when to stop pouring so as to not over-fill.

It’s no surprise that this mold is an excellent example of the benefits of stainless steel kitchen tools. For instance, it won’t retain the flavor of the last popsicles you made. It’s easy to clean, and unmolding the popsicles doesn’t require much more than running the container under warm water. While the popsicle rack requires dedicated freezer space, this mold was one of the more compact models we tried. Investing in this mold is the perfect option if you live in a warm climate and are a year-round popsicle consumer or simply a popsicle fan.

Once you've decided on the best popsicle mold (for humans!) from our comprehensive list of tested favorites above, we suggest you add Cooper's Pupsicles to your cart to treat your furry friends, too.

The team tested the material’s luminescent efficiency to be 15.1%, ten times higher than existing degradable luminescent polymers. The polymer can be degraded at the end of life under mild acidic conditions or heat treatment of around 410°F. The resulting monomers could be isolated and polymerized for reuse.

We tested a number of other popsicle molds that didn’t quite meet our standards, including more models from Tovolo, Zoko, Manba, and more. With some models, we struggled to release the popsicles from the mold, even when using the tricks up our sleeves. With others, we experienced some spillage, felt the construction wasn't quality or was too flimsy, were too much of a pain to fill, or were simply unsatisfied with the end result.

The best material for popsicle molds depends on your preferences. For a flexible, dishwasher-safe, and reusable option, silicone is a popular pick. On the other hand, plastic is a lightweight alternative that is often less expensive and just as easy to use. Stainless steel, though more expensive, is durable, easy to clean, and won't impart any weird flavors or smells.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

Regardless of the shapes, getting the pops out of the mold is as simple as twisting and gently pulling. The silicone material is flexible for easy release. Attractively designed, it comes in several colors and shapes and is dishwasher-safe. The mold also fits into a freezer nicely without taking up too much room.

Unfortunately, unmolding a single pop without unmolding the whole tray is impossible, so plan on serving these to a crowd when ready to enjoy. Despite the malleability of the silicone mold, the tray is small enough to be sturdy. Between that and how short the sticks are, this mold should have no problem squeezing in between that bottle of vodka and wintertime rations you’re storing in your freezer.

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

Researchers incorporated a ter-butyl ester into thermally activated delayed flourescence (TADF) polymers. This creates a functional group that enables subsequent thermal or acid depolymerization.

“Design is still compatible with processability and, in the end, you have to use this in real applications,” says Yuepeng Zhang, a materials scientist at Argonne and publication co-author. The researchers predict this new polymer can be applied to existing technologies, such as displays and medical imaging, and enable new applications.

Generally, hand-washing popsicle molds makes them last longer. Some molds come with cleaning brushes, making it easier to get in the nooks and crannies when cleaning up. For most, a little soap and hot water are all it takes.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Tovolo Classic Pop Molds ($14 at Amazon)These are designed for mess-free eating with an effective drip catcher. The molds click into the base so popsicles can be unmolded individually. However, these are so kid-friendly that they aren’t comfortable for adult hands to hold.

The design and sturdiness of each mold were essential factors, as one wrong move with a flimsy popsicle mold might mean sticky fruit juice all over your counter or, worse, inside your freezer and its ice trays. We also considered if the molds were a convenience in the kitchen, as freezer space is a precious resource. Did the molds take up too much space? Were they stackable? Can individual popsicles be detached, or must the whole mold be unmolded?

When testing, the resulting popsicles were solid and had great shape. No wider than eight inches, the mold didn’t take up too much space in our freezers, and they were sturdy enough to be worry-free when it came to spilling. We also liked how this set comes with a funnel, which makes pouring quick and mess-free. It’s a high return on investment for popsicle lovers everywhere.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Most popsicles require nothing more than a bit of patience. The simplest way to remove a popsicle from its mold is to leave it at room temperature for 1–2 minutes. For particularly stubborn pops, running the mold under lukewarm water does the trick. It’s also important to note that the unmolding process is usually easier when a mold is made of a more malleable material, like silicone.

You need to pay attention to the inherent characteristics of biopolymers PHA/PLA materials when setting process parameters to realize better and more consistent outcomes.

If you have room in your freezer, a sturdy tray is a great option, as it minimizes the chance of spills, leakage, and uneven freezing. Not everyone has this kind of space. Compact or flatter molds, like those for mini popsicles, are often made of flexible silicone and are made to sit on freezer shelves or in a freezer’s door compartment.

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

Most popsicle molds, like sphere ice molds, for example, come in a variety of materials. These include plastic, silicone, or stainless steel. Plastic and silicone are typically easier to unmold than stainless steel, but both can retain the flavor of previously made popsicles. This isn’t something to worry about every time you think about putting ice pops in the freezer, but if using permeating flavors like alcohol, spice, or intense herbs, it’s something to consider. While stainless steel is highly durable, unmolding popsicles is sometimes a more prolonged process (like running the molds under water). They can also be bulkier and a pricier investment.
