Why KingStar Became Professional Cooler Box Manufacturer?

Diverse Hard Cooler Solutions

Half a century of industry experience has enabled us to polish a full range of hard and cold boxes, from small portable models to commercial high-capacity models: the mini model is suitable for single day hiking, and the ultra large capacity model can support multi day scenarios such as music festivals and fishing boat supplies. Each model focuses on long-lasting cold locking (48-200+hours, depending on the usage scenario) and full environmental durability, and uses food grade materials throughout the entire process, ensuring safety without compromise.

Custom OEM & ODM Services

Our team of 16 designers and 20 engineers produces an average of 200+original designs per year (most of which have been patented). Do you want an exclusive texture? Brand customized lock buckle? Even insulation layers that are suitable for specific climates? We will first provide 2D/3D samples for your confirmation, and then use NDA to secure confidentiality – your creativity belongs only to you.

Scenario Based Functional Innovation

We have added a “practical buff” to the cold box: some models have built-in partition compartments (which can hold both cold drinks and fresh food at the same time), outdoor models are equipped with leak proof drainage valves and portable handles/shoulder straps, and commercial models have reserved printing areas and stacked card slots (convenient for storage and display) – making the cold box more suitable for specific usage pain points beyond “basic refrigeration”.

Rigorous Quality Assurance

60+quality inspectors do not conduct “paper inspections” – instead, they test the cold box through real-life scenarios: a 3-foot drop test, 72 hours of ultraviolet exposure, internal inspection of cold locking ability, and dual verification by a third-party laboratory. If it does not meet Igloo level standards, it will never leave the factory.

Professional Support Team

Our sales team is not only “responsive”, but also knows how to “pave the way ahead”: 7-day sample production? Cross border logistics quotation? Temporary adjustment of design details? Responding within 24 hours is the foundation, and we will proactively remind you of potential risks (such as material delivery dates) to help you firmly grasp the project pace.

One Stop Manufacturing Service

KingStar offers one-stop manufacturing services from creativity to finished products: from concept refinement and CAD model implementation in the design and engineering stages, to multi technology prototype sampling and functional testing in the prototype verification stage, to injection molding/CNC and other production processes adapted to high and low order volumes in the mass production stage, and finally delivering finished products that can be directly put on shelves through assembly, labeling, packaging and other links – the entire process is controlled by a professional team to ensure quality and confidentiality, allowing your creativity to be efficiently transformed into high-quality products.

Features of Our Ice Coolers

Long-lasting Antibacterial Material

The inner layer of the box is made of antibacterial modified materials and has passed food grade antibacterial certification – it can inhibit the growth of common bacterial groups. Even when storing fresh, fruit, and ready to eat food, it can reduce the risk of odor and spoilage, especially suitable for food storage and transportation scenarios in catering and fishing industries.

Dual Effect Temperature Control

By using high-density PU insulation layer and sealed temperature locking structure, not only can the ice cubes last for 3-8 days (suitable for outdoor refrigeration), but they can also maintain a long-term temperature lock for 3-8 days – storing ice drinks in summer and hot food in winter (such as hot soup for outdoor camping or hot lunch at construction sites). One cold box can meet the needs of both directions.

Wide Capacity Options (5L–80L or Customed)

We offer a 5L mini version (suitable for single person hiking), an 80L large capacity version (able to hold 20 servings of ingredients), and non-standard capacity customization – such as a 12L separate cold box for catering brands and a 60L compartment version for fisheries, to match the scene as needed.

Effortless Design

Equipped with anti slip handles on the sides and a foldable telescopic handle on the top, even when filled with ice drinks and ingredients, it can disperse weight with one or both hands; Some large-sized models also add bottom rollers, making outdoor towing and warehouse handling more effortless.

Practical Detail Design

There are hanging buckle holes on the side of the box, which can be mounted on tents to save space; The drainage valve adopts a leak proof thread design, which avoids spillage and makes cleaning more convenient; The inner side of the box is equipped with a mesh bag compartment, which is convenient for storing small items such as bottle openers and wet wipes, making access more efficient.

Hard Cooler Upgrade Solution

Igloo of Equivalent Quality

Referring to Igloo’s strict product standards, we carefully select food grade LLDPE material to create the box, which is impact resistant, UV resistant, and suitable for complex outdoor environments; Equipped with a high-density food grade insulation layer, the ice retention time is comparable to the classic Igloo model. From personal portable to commercial high-capacity models, all products in the series have undergone multidimensional verification such as high and low temperature testing and drop testing to ensure durability and safety.

Flexible Customized Service

Relying on a core team of 16 designers and 20 engineers, we provide comprehensive customization services covering appearance, color matching, brand identity, and functional upgrades, supporting Flexible MOQ (Minimum Order Quantity). Whether it’s the optimization and improvement of popular Igloo replicas or the exclusive development of original designs, with an annual output of over 200 patented designs, we can quickly respond to personalized brand needs and sign confidentiality agreements throughout the entire process to ensure creative security.

Full Link Service Support

We provide one-stop services including quotation, sampling, order tracking, logistics coordination, and after-sales support. Our sales team responds quickly 24 hours a day, and over 60 quality inspectors control the entire process of quality. In response to the brand’s overseas demand, we can assist in completing certification procedures that meet the requirements of the European and American markets, while providing customized packaging solutions to make the entire process of cooperation from product to landing worry free and efficient.

How to Choose the Best Hard Cooler For You?

Igloo hard cooler

Before buying a hard cooler, be sure to think carefully about how and where you plan to use it. Whether it’s backyard barbecue, weekend fishing, or a few days of camping adventure, choosing the right model and features will keep you comfortable to use.
The following points are key considerations when selecting high-performance cooler boxes:

  1. Core Temperature Control Capability
    Prioritize the material and thickness of the insulation layer, and choose high-density PU foam insulation layer (thickness ≥ 3cm is preferred), combined with a sealed lock design, which can effectively reduce cold and heat exchange. At the same time, pay attention to the official labeling of the cooling/heating duration. For outdoor camping, choose the model with cooling for 3-7 days, and for short picnics, choose 1-3 days.
  2. Material and Durability
    The preferred material for the outer shell of the box is food grade LLDPE, which is impact resistant, UV resistant, and not easily cracked, making it suitable for complex outdoor environments; Avoid selecting recycled materials as they are prone to aging and deformation. In addition, it can be checked whether the product has been certified through actual testing such as dropping, exposure to sunlight, etc., to ensure durability.
  3. Matching Capacity and Portability
    Choosing the capacity of a hard cooler based on the number of people and the scene won’t be wrong: for single person hiking, the 5-20L mini model is just right and doesn’t take up space in a backpack; For family camping with 3-5 people, a size of 30-80L is the most suitable, as it can hold ingredients, cold drinks, and fruits; If it’s for team activities or commercial use, you can choose high-capacity models with 100L or more.

4. Practicality of Detail Design
Pay close attention to whether the drainage valve is designed with leak proof threads to prevent spillage during drainage; Is there a storage mesh bag on the box cover for easy storage of small items; Is there a buckle hole on the side that can be mounted on the tent or rear of the car to save space. In addition, models with partitioned compartments are more suitable for storing different ingredients simultaneously.

5. Additional Features and Compliance
If used for food storage and transportation, priority should be given to models that have passed FDA food contact certification; Outdoor high-frequency use can pay attention to the design of antibacterial inner tanks to reduce the growth of odors. If there is a need to go abroad, it is necessary to confirm whether the product meets the CE, ROHS and other certification standards of the target market.

6. Brand and After-sales Support
When choosing a brand, you need to look at the after-sales service. Priority should be given to those with a clear warranty period, such as 1-5 years, for better protection in case of future problems. In addition, you can also take a closer look at everyone’s real usage feedback, focusing on whether the insulation effect will deteriorate after prolonged use and whether the parts are easily damaged.

FAQs question mark

Frequently Asked Questions

What is the Price of Igloo Hard Sided Coolers Compared to Competitors?2026-01-05T08:58:35+00:00

Igloo is a cost-effective option, much cheaper than high-end brands such as Yeti and RTIC. For example, a 50 quart Igloo costs around 7-20 dollars, while a high-end model of the same size costs over 70 dollars. Igloo is sufficient for picnics and trunk gatherings, and it also saves money.

Can You Label Igloo Ice Chests With Your Own Brand Logo or Customize a Style?2026-01-05T08:58:13+00:00

You can OEM (print your own logo on regular models) or customize in small quantities (such as changing colors and sizes), but you need to meet the minimum order quantity – usually 500 or more. You also need to coordinate with Igloo’s design team to see if they can do it.

Igloo Ice Boxes are Cheaper Than Others, Is It Due to Poor Materials?2026-01-05T08:57:36+00:00

Not really. Igloo is an old brand. It is made of food grade plastic shell and thick foam insulation layer. The basic quality is enough.
Cheaper is because of the high efficiency of the production process, not cutting corners on core materials, and there is no problem with daily use.

Does the Color of the Cooler Box Affect the Insulation Effect?2026-01-05T08:57:07+00:00

Yes. Dark colors such as black and dark blue are prone to absorbing solar heat, and when used in high sunlight, the ice retention time will be slightly shorter than light colors such as white and light gray.
If you often expose yourself to the sun outdoors, choosing a light colored one can better protect the ice.

What is Pre Cooling? Can Ice Really Melt Slowly?2026-01-05T08:56:36+00:00

Pre cooling refers to freezing an empty refrigerator with ice cubes/packs for 1-2 hours before loading. Definitely useful! The temperature of the cooler box itself is the same as room temperature. Pre cooling can first lower the temperature inside the box, and the ice cubes do not need to exert extra effort to cool the box. The ice retention time can be extended by several hours.

How Much Ice Should Be Placed in the Igloo Hard Cooler?2026-01-05T08:56:07+00:00

According to capacity, approximately 2 pounds of ice per quart (about 1 liter) of space, or ice and contents in a 2:1 volume. For example, a 50 quart box can hold 100 pounds of ice paired with 50 quarts of items, with empty spaces filled with ice.

The Ice Retention Time of the Igloo Hard Sided Cooler is Not as Long as Before, What Should I Do?2026-01-05T08:55:36+00:00

Try these tricks:
1. Pre cool: Before loading, put ice cubes/ice packs in an empty container and freeze for 1-2 hours to lower the temperature inside the container.
2. Add more ice: Try to let the ice occupy 2/3 of the space and leave fewer gaps (as larger gaps make it easier for warm air to enter).
3. Open the lid less: Open and close things quickly, don’t keep them open all the time.
4. Check for damage: Check for cracks in the box body and loose sealing strips – if there are any problems, repair/replace them.

What Should I Do If My Igloo Cooler Box is Broken?2026-01-05T08:55:09+00:00

Let’s first check if it’s within the warranty period (Igloo hard sided coolers usually have limited warranty):
-If under warranty, prepare purchase receipts (receipts, order records), contact Igloo customer service to submit a warranty claim, and follow their instructions to send it back for repair/replacement.
-If the warranty is expired, small cracks can be repaired with food grade cooler box tape; If it cracks severely or the insulation layer is damaged, replacing it with a new one would be more practical.

Can Igloo Hard coolers Withstand Outdoor Construction by Residents?2026-01-05T08:54:05+00:00

Yes, they can. Its shell is made of impact resistant plastic, which can withstand outdoor bumps, wind and sun exposure without any problems. The insulation layer can also stabilize the temperature in warm environments.
Of course, don’t intentionally create it (such as dragging over sharp stones), but ordinary camping and beach play scenes are completely manageable.

Is the Igloo Hard Cooler Waterproof/Sealed?2026-01-05T08:53:52+00:00

Igloo hard coolers are not completely sealed or waterproof – this is specifically designed. If it is made fully sealed, the temperature difference between the inside and outside of the box will create pressure, and after a period of time, the box lid will hardly open.

However, it is splash proof: daily ice cubes, beverages, and food will not leak, but they cannot be used for floating, nor should they be completely immersed in water – do not use them as floats, and do not completely submerge them.

What is your payment term?2025-06-30T03:26:23+00:00

We offer flexible payment terms and several secure methods for your convenience.

Payment Methods:

  • Wire Transfer (T/T)

  • PayPal

  • Western Union

Payment Terms:

  • Mold payment: 50% deposit upfront, 40% upon T1 sample approval, and the remaining 10% after final approval.

  • Product payment: 30% deposit upfront, with the remaining 70% due before product shipment.

If you have specific payment requirements other than those mentioned above, feel free to contact and discuss them with us (via our email: sales@kingstarmold.com, or sending a quote by filling out the table on this contact page). We’re always open to finding a solution that works for both sides.

How long is the sample lead time?2025-06-30T04:34:30+00:00

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?2025-06-30T04:35:35+00:00

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.
