Useful Plastic Products You Can Manufacture Using Rotomolding Technology

by Olufisayo

Are you into plastic product manufacturing and planning to diversify your offering? You need to adopt the rotomolding technology for you to produce products of different sizes, shapes, and designs. The process has many benefits like quality surface finish, customization, and cost-saving.

What Exactly is Rotomolding?

In rotomolding, also called rotocasting and rotational molding, a rotating mold allows you to produce thermoplastics into useful products. The pattern is usually made of cast aluminum and sheet steel.

During the process, an operator fills the mold with the plastic raw material, which is usually in powdered form. As the mold is heated and rotated, the plastic powder softens and takes the shape of the pattern. After forming, the mold is cooled to allow the product to solidify. The product is then separated from the mold through the demolding process.

What Are the Plastic Materials Used in Rotocasting?

There are several types of plastic you can use in rotational molding. However, the majority of producers favor polyethylene (PE). PE is a grade of polyolefin that can be quickly grounded into powder form at room temperature.

The other plastic materials commonly used in rotomolding are polypropylene, polycarbonate, polyvinyl chloride, and nylon.

What Plastic Products Can You Produce by Rotational Molding?

Due to its versatility, the products you can manufacture through rotomolding are limitless. Designers can explore many concepts and techniques in the design process due to the technology’s customizable nature. Here are some of the plastic products you can create:

  • Storage tanks – Through rotocasting, you can produce storage equipment with a capacity of up to 50,000 liters. You can use the products to store liquids like chemicals, sewage, fuel, and water. Among the plastic tanks are septic tanks, water treatment tanks, and fuel tanks.
  • Children’s products – You can manufacture quality children’s products like toys, plastic balls, and playground equipment.
  • Outdoor accessories – Rotational molding is ideal in producing outdoor furniture, rain barrels, planter boxes, and other outdoor essentials.
  • Containers – Among the products you can produce are combo bins, refrigerated boxes, shipping containers, bulk plastic containers, as well as drums and barrels.
  • Industrial products – You can manufacture plastic products for industrial purposes through rotocasting. Products from rotomolding are very durable. They can withstand the harsh environment in the industrial sector. Some of the industrial products include blower housing, water filtration systems, and recycling units.
  • Medical products – Safety is essential in the medical field. Among the durable plastic products for the sector are facial oxygen masks, paramedic cases, stretchers, and casing for medical samples and specimens.
  • Marine equipment – Plastic products are ideal for the marine industry due to their durability, non-corrosive features, and lightweight. Among the rotomolding products for the sector are buoys, dock floats, recreational watercraft, and pool liners.
  • Transportation industry products – There are numerous plastic products needed for the transportation sector. Through rotocasting, you can manufacture things like tractor dashboards, vehicle instrument panels, diesel fuel tanks, and ducting.
  • Material-handling – Some of the material-handling products include pallets, cooler boxes, crates, utility carts, shipping containers, and packaging supplies.

As a plastic manufacturer, you need to diversify your product offerings to cover more markets and industries. The adoption of rotomolding technology into your operation can open doors for potential expansions. These opportunities will significantly improve your bottom line.
