Custom Roto Molding
At Hive Plastics, custom roto molding is at the core of how we help businesses bring durable, large-scale plastic products to life. With advanced equipment and a skilled team, we specialize in creating seamless, high-performance components built to meet exact specifications without compromising on quality.
From concept to completion, our process is designed for flexibility, strength, and long-term reliability. Whether you need a 3000 gallon tank or another large rotational molding solution, we deliver products that perform in demanding environments while maintaining consistent quality across every production run.
Large Rotational Molding Capabilities
Hive Plastics is equipped to handle large rotational molding projects that many manufacturers cannot support. Our process allows us to produce oversized, hollow plastic products without compromising structural integrity or uniform wall thickness. This makes roto molding ideal for applications that require durability, impact resistance, and weatherability.
Because rotational molding does not rely on high-pressure injection, it enables the creation of complex shapes with consistent material distribution. This results in stronger corners, reduced stress points, and longer product lifespans. For businesses that need reliable, large-capacity plastic solutions, our capabilities ensure both scale and precision.

Custom Product Possibilities
The high-temperature and low-pressure plastic forming process of rotational molding can create a variety of products. Creating a seamless product is easy when you work with Hive Plastics. Our custom molds and engineering options allow us to create all types of products, from smaller parts to large-scale projects. Many industries trust our rotational molding processes to create storage options, trash cans, outdoor products, and more.
Tanks
Storage tanks can help protect a precious resource from contamination or evaporation. Our crafted water tanks can be utilized for industrial or residential uses, such as separating fresh water and wastewater. We have molds that can create smaller water storage options or larger containers of up to 500 gallons. Hive Plastics creates molds that will continue to be supportive and durable through years of use.
Bulk Containers
One of the biggest benefits of working with a rotational molding company is that you avoid weak points because the product is crafted as one large piece, instead of installing sides and closures separately. Bulk containers can be utilized for many different tasks in your business, allowing your team to have a better workflow. Hive Plastics creates bulk containers that can contain large quantities of material, tools, or inventory.
Pallets
Rotational molded pallets can be used for awkward and heavy loads, even in the harshest environments. Plastic pallets can work better in outdoor environments or harsh industries where wood pallets may not hold up. These molded pallets can help support transfer loads and are reusable for many deliveries or projects. Our team can help you craft pallets that will either be handled by forklifts or material handling machines, so your product works for you.
Trash Cans
We partner with businesses as a custom contract manufacturer to engineer high-endurance waste management solutions from the ground up. Our advanced rotational molding process forms each container as a single, seamless piece with uniform wall thickness. This completely eliminates the structural seams and weak points inherent to traditional injection-molded retail trash cans. Our custom molding capabilities ensure your product delivers unmatched impact resistance and long-term industrial value.
Laundry Carts
Industrial laundry carts can help with more than just linens; in fact, the thorough design of rotational molding carts can help you transfer soiled linens, clothing, or damaged materials that need to be cleaned. Crafted in one piece, laundry carts from our team at Hive Plastics will make your daily laundering much easier and smoother. Depending on your industry, we offer varying sizes of carts that will fit nicely in your space or handle the number of lines you handle on a daily basis.
Outdoor Product Manufacturer
Enjoying time outdoors is often more enjoyable when you have durable products. Outdoor tables, recreational toys, or coolers can be crafted by our team to help serve your gatherings or outdoor hobbies. Our products are crafted to withstand sun exposure, dirt and debris, and excess moisture.
Other Custom Products
If your business needs a part or product that our company doesn’t offer, we can help you craft something unique. Hive Plastics can create new molds for your industry that will create a part without weak points. Customize your product to beat your competitors, provide better longevity for those who use your product, or build a product that may become more useful for more than just your business.
