Frequently Asked Questions

Are your hard coolers built to handle rough outdoor conditions?webadmin2025-07-07T05:02:54+00:00

Are your hard coolers built to handle rough outdoor conditions?

Absolutely—these hard coolers are built to laugh off rough outdoor conditions. The outer shell’s UV-resistant, so baking in direct sun won’t make it fade or crack, even after years. They’re tough enough to take drops, drags over rocks, or gear stacked on top without denting or warping. Extreme heat? Freezing cold? No problem—they hold their shape and performance.

And here’s a detail that matters for backcountry trips: The thick walls and heavy-duty latches aren’t just for durability—they stand up to curious wildlife too. Whether it’s a curious bear checking things out or other critters, the solid build and tight-sealing design mean they won’t easily pop open.

We’ve spent years refining these coolers, even crafting them to meet the same tough standards as the industry’s top brands. So whether you’re camping deep in the woods, boating through choppy waters, or tailgating in the mud, they’ll keep up. No shortcuts—just the kind of ruggedness that’s made to outlast the adventure.

Do your hard coolers have features to make them easier to carry?webadmin2025-07-07T05:00:30+00:00

Do your hard coolers have features to make them easier to carry?

Absolutely. We design with portability in mind, and it depends on the size: Smaller coolers (20–35 quart) have sturdy side handles for easy lifting. Medium to large ones (45+ quart) often come with heavy-duty rope handles or padded grips, and many 70+ quart models add wheels—perfect for rolling over sand, dirt, or pavement without straining. Some even have a telescoping handle to pull them smoothly. No matter the size, we make sure they’re easy to move, even when full.

Can I use dry ice in your hard coolers?webadmin2025-07-07T04:57:56+00:00

Can I use dry ice in your hard coolers?

Yes! Our hard coolers are dry ice compatible (but not soft coolers). Here’s how:

Use 1–2 lbs of dry ice per 24 hours.
Place it on top of regular ice or wrap it in newspaper to prevent direct contact with food.
Leave the drain plug slightly open to release pressure.

Note: Dry ice can keep items frozen for 1–2 days longer than regular ice .

How long is the sample lead time?webadmin2025-06-30T04:34:30+00:00

How long is the sample lead time?

The lead time for samples can vary depending on your specific project. Here’s a general idea:

Standard parts or existing molds:
If your part matches something we already produce, samples usually take about 3 to 7 days, depending on stock and shipping times.
Custom molded or machined parts:
For new designs that require custom molds or mechanical processing, it usually takes 2 to 5 weeks to produce samples. This period includes the time for mold fabrication, preparatory work, and making minor adjustments according to your requirements.
3D-printed prototypes:
If you need to obtain the prototype product quickly, we also offer 3D printing services in metal or plastic materials. These samples can usually be completed within 3 to 5 days, depending on factors such as size, material, and surface treatment requirements.
Special finishes or testing:
Surface treatments like anodizing, black oxidize, painting, etc.(click here to see our options), or specific functional tests might add a bit more time.

Once we know your part details, we’ll confirm the timeline and keep you posted throughout the process. Feel free to share your drawings or ideas so we can give you a more precise estimate!

Can I get samples for testing?webadmin2025-06-30T04:35:35+00:00

Can I get samples for testing?

Yes, absolutely. At KingStar, we understand how important it is to check the quality and fit of your parts before moving into mass production.

In most cases, we can provide samples in small quantities — usually between 1 and 10 pieces (for 3D printing, CNC machining), or 10 to 100 pieces (for injection molding) depending on your part’s size, complexity, and production method.

We offer several options for making samples:

3D Printing (Metal or Plastic): Great for fast prototypes or design validation, usually ready in just a few days. We usually provide 1-3 pcs as samples.
Trial Runs from Injection Molding: For plastic parts requiring high accuracy or specific materials, we can run small batches (usually 10-100 pcs) using soft or production tooling.
CNC Machining: Ideal for metal or plastic parts needing precise tolerances or certain material properties before committing to tooling. For machining, we usually provide 1-5 pcs as samples.

However, this is not fixed. If you need more samples than we usually provide, we are open to negotiate, and if your project requires special finishes, surface treatments, or functional testing, we’re happy to include those in the sampling process as well.

Let us know your part details, and we’ll advise the best way to produce your samples quickly and cost-effectively.

Can hard coolers be used for both hot and cold storage?webadmin2025-07-07T03:24:56+00:00

Can hard coolers be used for both hot and cold storage?

Yep, our hard coolers are total multitaskers—they’re built to handle both hot and cold storage like a pro.

For cold stuff? They’re absolute champs. Thanks to that high-density, closed-cell polyurethane (PU) foam insulation we use—plus the tight silicone gasket sealing the lid—they lock in cold to keep ice frozen for 3 to 8 days under regular outdoor use. Whether you’re packing cold drinks for a weeklong camping trip, fresh produce for a picnic, or frozen snacks for a tailgate, the rigid shell adds extra protection against outside heat, so your stuff stays frosty far longer than flimsy coolers.

And when it comes to hot storage? They step up just as well. That same insulation doesn’t just trap cold—it locks in heat, too. The sturdy build (no flimsy walls here) and tight seal keep hot drinks like coffee or tea warm (over 140°F/60°C) for 48+ hours, and hot foods like soup or chili heated safely (above 165°F/74°C) for 24+ hours. Perfect for early morning hikes, all-day work sites, or camping meals where you want something warm hours later.

Cheap hard coolers might fizzle out on one or the other, but ours? They’re engineered to excel at both. Need a cooler that keeps things icy and toasty, no matter the adventure? That’s what we build ’em for. Reach out if you want to find the right one for your needs.

How long can a hard cooler keep items cold?webadmin2025-07-07T03:30:38+00:00

How long can a hard cooler keep items cold?

How long a hard cooler keeps items cold boils down to one big thing: quality.

Cheap, low-quality hard coolers? They’re usually made with thin, flimsy foam insulation and loose lids that let cold seep out fast. Even in mild conditions, they might keep things cool for 12 hours at most—if you’re lucky. Leave them in direct sun or open the lid a few times? That cold could fizzle out in half that time.

Our high-quality hard coolers? It’s a whole different story. We build them with thick, high-density polyurethane foam insulation and tight-sealing silicone gaskets that lock cold in and block heat out. That means they’ll keep items cold for 3 to 8 days—but exactly how long depends on how you use them and the environment. Hot, sunny days or frequent lid openings will shorten it; keeping the cooler in shade and limiting how often you open it? It’ll stretch that cold retention even longer.

Want to squeeze every last hour of cold out of your cooler? Our guide, How to Pack a Cooler for Maximum Ice Retention, breaks down pro tips for packing—like layering ice, pre-chilling the cooler, and organizing items to minimize heat loss. It’s a game-changer for getting the most out of your cooler, no matter the adventure.

At the end of the day, it’s simple: cut corners on quality, and you’re stuck with a cooler that quits after 12 hours. Invest in a well-built one? You’ll keep things icy for days. That’s the difference we build into every cooler we make.

Is it easy to clean the coolers?webadmin2025-07-07T04:36:06+00:00

Is it easy to clean the coolers?

Yes, cleaning hard coolers is generally straightforward, thanks to their durable construction and smooth interior surfaces. Here’s why they’re easy to maintain:

• Smooth, Non-Porous Surfaces:
Hard coolers, especially high-quality models, typically feature smooth, non-porous interiors that make it easy to wipe off dirt, food residue, or spilled liquids. This prevents bacteria and mold from accumulating, which is crucial for hygienic storage.

• Drainage Plug for Easy Water Removal:
Most hard coolers come equipped with a drainage plug at the bottom, allowing you to easily empty out any melted ice or excess water without tipping the cooler over. This feature helps in the cleaning process and prevents water from stagnating inside.

• Removable Trays or Baskets:
Some models have removable trays or baskets that can be cleaned separately, which makes it easier to keep the inside of the cooler free from debris and odors. These removable parts can be wiped or washed, ensuring your cooler remains clean and functional.

• Simple Cleaning Solutions:
To clean your cooler, you typically need mild soap and warm water. For tough stains or odors, a mixture of baking soda and water can be used to scrub the interior. If the cooler has an odor, a simple solution is to leave it open in a well-ventilated area after cleaning.

• Regular Rinsing and Maintenance:
With regular rinsing and the occasional deeper cleaning, hard coolers can remain in excellent condition for years. Some users may choose to use specialized cooler cleaning products, but basic cleaning tools and products work just fine.

If you need specific steps or instructions, we have a post that specifically explains how to clean your cooler. You can refer to it.

What is the advantage of a cooler box?webadmin2025-04-07T05:49:56+00:00

What is the advantage of a cooler box?

A cooler box—especially a high-quality hard cooler—offers a wide range of benefits for both recreational and professional use. Whether you’re camping, fishing, tailgating, or transporting temperature-sensitive goods, here are the main advantages:

• Superior Temperature Retention:
Hard cooler boxes are built with thick insulated walls, often filled with high-density polyurethane (PU) foam. This insulation traps cold air inside and blocks external heat, keeping ice solid and contents cold for days—even in extreme temperatures.

• Durability and Impact Resistance:
Unlike soft coolers, hard-sided cooler boxes are made from rugged materials like rotomolded polyethylene, which resists cracking, denting, and UV damage. This makes them ideal for tough environments like camping trips, fishing boats, or construction sites.

• Versatile Storage Options:
Cooler boxes can store not only beverages and food but also fish, bait, medical supplies, or any other temperature-sensitive items. Some models even offer dry storage compartments, cutting boards, cup holders, and built-in bottle openers for added convenience.

• Can Keep Items Hot or Cold:
Thanks to their excellent insulation, cooler boxes can maintain both hot and cold temperatures. This means you can use the same cooler to keep soup or cooked meals warm for hours, depending on your needs.

• Portable and Easy to Clean:
Despite their solid construction, most hard coolers come with carry handles, wheels, or tie-down slots for easy transportation. Their smooth inner surfaces also make them easy to rinse out and sanitize after use.

• Waterproof and Leak-Resistant:
A well-sealed hard cooler prevents leaks and keeps water out, making it a reliable dry storage container in wet or unpredictable environments. Many models include a drainage plug for easy water removal without tipping the cooler over.

• Long-Term Value:
With proper care, a quality cooler box can last for many years. It’s a smart investment for anyone who regularly needs reliable thermal performance and durability in demanding settings.

Whether you’re spending a day at the beach or transporting food to remote job sites, a hard cooler box offers unbeatable functionality, protection, and performance.

Are the materials used in hard coolers food-safe and BPA-free?webadmin2025-07-07T04:47:22+00:00

Are the materials used in hard coolers food-safe and BPA-free?

Absolutely. All materials in our hard coolers—from the outer shell to the inner liner—are food-safe and 100% BPA-free. We use food-grade plastics and certified insulation that meet global safety standards, so you can store drinks, snacks, or meals without worrying about harmful chemicals leaching in. Your food stays safe, and you stay confident.

What sizes do your hard coolers come in, and how do I choose the right capacity for my needs?webadmin2025-07-07T04:55:29+00:00

What sizes do your hard coolers come in, and how do I choose the right capacity for my needs?

Our hard coolers come in a bunch of sizes to fit different needs—from small enough for a solo trip to big enough for a whole group. Here’s the gist:

Common sizes (and when to use ’em)

20–35 Quart: Good for 1–3 people on day trips. Toss in drinks, snacks, and a little ice, and you’re set for a picnic or short hike.
45–60 Quart: Perfect for families (3–5 people) or weekend getaways. Holds enough food, drinks, and ice for 2–3 days of camping or a beach trip.
70–100 Quart: Great for longer trips (3+ days) or bigger groups (6+ people). Think multi-day camping, fishing, or group outings where you need supplies for days.
100+ Quart: Heavy-duty—for big gatherings, commercial use, or expeditions. Holds tons of food/ice for 5+ days.

How to pick?

Just think about your group size and trip length. 1–3 people out for a day? 20–35 quart works. 3–5 people camping over the weekend? 45–60 quart is better.

Need exact measurements? Specifics like height, width, and capacity details are on each product page—check the specs tab, it’s all there.

And if you need a custom size? We can do that too. Just hit up our sales team(sales@kingstarmold.com) and let ’em know what you’re after.

Easy enough, right? Let us know if you want help narrowing it down!

How Does a Hard Cooler Work?webadmin2025-07-07T04:44:53+00:00

How Does a Hard Cooler Work?

A hard cooler works by creating a super-insulated, tightly sealed space that slows down how heat moves in and out. That’s why it keeps stuff cold for so long—even when it’s hot outside. Let’s break down how it all comes together:

First off, the walls are key. The shell (usually tough plastic) isn’t just for looks—inside, there’s thick insulation. Top-quality coolers use dense polyurethane foam here, which is way better at blocking heat than the thin, cheap foam in basic models. Rotomolded coolers are extra good because their walls are seamless and packed with this thick foam, so outside heat has a hard time sneaking in.

Then there’s the lid seal. A good hard cooler has a rubber gasket (like the kind in your fridge) around the lid. When you shut it, that gasket squishes tight, making an airtight seal. No warm air gets in, no cold air escapes—that’s a big part of why the cold stays trapped.

The latches matter too. They’re not just to keep the lid closed—they press that gasket even tighter. Whether it’s a T-latch or a cam latch, the idea is to lock in that seal, so heat can’t wiggle through gaps.

Here’s the thing: A cooler doesn’t make cold—it holds onto it. You start with ice or ice packs, and the cooler preserves that cold. Block ice works better than cubes, by the way—less surface area means it melts slower, so it keeps things cold longer.

The materials help too. The outer shell is made of stuff that doesn’t let heat pass through easily, and the inside is usually smooth and light-colored, which reflects heat instead of soaking it up. Together with the insulation, that keeps the whole thing resistant to warmth.

Most have a drain plug at the bottom, too. When ice melts, you can drain the water without opening the lid (which lets heat in). Less water means less heat transfer, so the remaining ice lasts longer.

There are extra little features that help, too: Rubber feet lift the cooler off hot ground (like pavement or sand), so it doesn’t soak up heat from below. UV-resistant shells keep the outside from absorbing sunlight (which would warm things up). Even the lid has insulation—since heat rises, that extra layer stops warmth from seeping in through the top.

Curious about how similar containers (like cooler boxes or ice chests) work? We break it down in more detail in our post: How Does a Cooler Box / Ice Chest Work?

Bottom line: A hard cooler is basically a cold-trapping box. It uses thick insulation, tight seals, and smart materials to hold onto the cold you start with. The better those parts work, the longer your ice stays solid—and your drinks stay cold. That’s the difference a well-made cooler makes.
