Custom Molding: The Water Box

The Water Box™ is intended for direct watering from an available water source such as a dugout, slough, slow moving creek, etc. during the winter months. The Water Box™ is inserted through the ice surface of a desired water source, froze in and then self-utilized by livestock for 24-hour accessible drinking water.  Livestock access the water source by lifting the nose flipper located on The Water Box™ lid then place their heads into the watering receptacle to drink.

Emax Plastics is the Exclusive Manufacturer of The Water Box

What is Rotational Molding?

Rotational molding, also known as rotomolding, is a plastic forming process that is used to create hollow plastic products with a variety of shapes and sizes. This manufacturing process involves several key steps and offers numerous advantages, which have contributed to its popularity over the years.

Rotational Molding Process

1. Loading the Mold: The first step involves prepping the mold and adding pulverized polyethylene (we purchase Linear Low Density Polyethene in powdered form, but we pulverize and granulate our recycled products) and load it into a mold. The mold is then sealed to prevent any powder from escaping.


2. Heating and Rotating the Mold: The mold is heated by green natural gas while being rotated on two or more axes. The heat causes the polyethylene to adhere to the mold walls. The rotation at different speeds ensures that the polymer spreads evenly throughout the mold, resulting in a seamless, strong polished finish.


3. Cooling the Mold: After the heating process, the mold is cooled using fans until it can be safely handled. During cooling, the newly formed plastic part will shrink, making it easier to remove from the mold.


4. Mold Removal: A mold release agent (MRA) is often used to aid in the removal of the mold from the new product.


5. Finishing: Additional finishing processes include detailing and clean up, to enhance the product’s accuracy, consistency, and appearance.


6. Warehousing and Drop Shipping: Manufacturers like Emax Plastics may offer warehousing and drop shipping services for the products, allowing for efficient storage and distribution.

Advantages of Rotational Molding

1. Durability: Rotomolded plastic products are highly durable, impact resistant, seamless and can withstand a wide range of environmental conditions. They are UV enhanced, making them more durable than most other materials and are resistant to corrosion, rust or deterioration.


2. Cost-Effective: Rotomolded products are lightweight, which reduces shipping costs. Additionally, the manufacturing process itself is relatively cost-effective, especially for larger and bulkier items. Our Navigational Buoys are designed specifically without weights or cement, making their handling, shipping and storage costs even more cost effective than our competitors.


3. Design Flexibility: Rotomolding allows for design flexibility, including specifying wall thickness. It also enables the inclusion of molded logos, eliminating the need for product stickers that may peel over time.


4. Long and Short Productions: Rotomolding is suitable for long and short production runs (20-15,000 pieces).


5. Low Tooling Costs: Compared to some other plastic manufacturing processes, rotomolding typically has lower tooling costs, as it doesn’t require complex molds or extensive machining.


6. Environmentally Friendly: Rotomolding produces minimal waste, and any excess material can be recycled, making it an environmentally friendly plastic manufacturing method.
