Customers love rotomoulding for the high-quality products and low cost of tooling. Rotomolded plastic components have high tensile and uniform wall thickness. They also feature a single-piece design.

The capabilities of products are virtually limitless in the industry. Rotomolding is a rising trend in manufacturing. It allows products that are less durable to be converted into rotomolded products. Rotomolding has many advantages due to the process and the properties of the materials. You can convert rotomolding products to pallets, agricultural tanks, or drainage piping.

Rotationally molded plastics are thermoplastics that are made using or rotomolding. Thermoplastic material is a plastic material that will shrink when it is heated and then cooled again. The rotomolding process requires only a high-heat revolving mold. Its single-piece construction makes rotationally molded plastics hollow and has high tensile strengths and uniform wall thickness.

Rotomolding has become a popular choice in road construction and agriculture, plumbing, and sporting goods.

Materials Used For

Many different plastics can be rotationally molded. For example, you can mold polyethylene (PE), high-density, cross-linked, polyethylene (HDPE), linear-low-density, and polyvinylchloride plastics (PVC). Polyethylene, a lightweight plastic, has a low modulus.

Polyethylene (PE), also known as polythene, is the most commonly used of all plastics. Although it’s not very strong, it has excellent impact resistance, rigidity, and toughness. It is also ductile. The most common products made from rotationally molded polyethylene include bottles, pipes, bins, and other containers.

  • Cross-Linked Polyethylene: Cross-linked Polyethylene has excellent impact strength, environmental stress cracking resistance, and abrasion resistance. This type of PE can also be used for products that will be subject to shallow temperatures.
  • HDPE High-Density Polyethylene:  It promises to be resistant to cold temperatures. In addition, the high-flow molding and high molecular weight thermoplastics offer products with interior gloss.
  • LDPE: The advantages of rotationally molded linear, low-density, polyethylene parts include superior fit and finishing, as well as high impact and tensile strength. The benefits of rotationally molded linear low-density plastic ethylene parts include superior fit, finish, and high tensile or insulation strengths.
  • Polyvinylchloride: Or vinyl, commonly known as PVC or vinyl, has outstanding chemical resistance, high transparency, and long-term stability. It also offers good excellent flow characteristics, stable electrical properties, and superior weatherability. In addition, it can be either flexible or rigid.

Process

  • 1. The first step in making rotationally molded plastics is to make a mold from metal. After the material has been loaded into it, spindles (arms) support it. This is called the charging stage.
  • 2. The molds are loaded and transported to a heat chamber. The molds will be heated and rotated along with the horizontal and vertical spindles until they melt. This low-pressure method allows the molten material to be coated evenly on the walls of the mold cavity.
  • 3. The cooling stage is the third phase in roto-molding. Here, water and air cool the mold and dry it for about 20 minutes.

R&R Technologies LLC considers several requirements when designing a rotated molded plastic component. Specifications include product size, requested product color, product form, product shape, and standard conditions. Based on these specifications, they will determine details such as the material type (including various plastic resins or additives), rotomolded style, and process type.

We can design a custom mold to make custom rotomolded components and make allowances for custom texture and finish as well as color or labeling. Labeling can be done with logos, graphics, or other imprints.

Products: The Advantages

Rotomolding offers many benefits. Rotomolding can be done without stress and produces parts that will last longer than other forms of plastic. Most commonly, rotomolding uses polyethylene. Polyethylene has a long life span, is waterproof against the elements, and is one of the most durable materials available.

Rotomolded plastics are also easily customizable to meet FDA standards. For example, it’s easy to design a mold that forms a label, logo, or graphic into a Rotomolded Plastic product. In addition, rotomolded pieces are lightweight and can be customized in color, texture, finish, and density.

Rotomolded parts of polyethylene are typically lighter than many other materials. Rotomolding products can be used outdoors in the sunlight provided that they are made with the appropriate materials. It’s is why playground equipment is often made from rotomolding.

Polyethylene can also be exposed without deterioration to different caustic chemicals, and it’s why many chemical tanks have been rotomolded. Many stainless-steel tanks are fitted with a PE liner which can be rotomolded inside. FDA regulations for manufacturing can be met through the rotomolding process using specific grades of certified prima virgin materials. Rotomolded products are standard in the food sector due to their variety.

The industry has almost unlimited capacity for rotomolded products. Rotomolding is a rising trend in manufacturing. It allows products that are less durable to be converted into rotomolded products. Rotomolding has many advantages due to the process and the properties of the materials. You can convert rotomolding products to pallets, agricultural tanks, or drainage piping.
