Rotational Molding Delivered on Time!
Servicing Industrial, Automotive and Commercial Markets
R&R Technologies LLC is a nationwide plastic rotational molding provider and is ISO 9001:2000 registered and a member of Association of Rotational Molders International. We are located at 7560 East County Line Road, Edinburgh, IN 46124, Ph: (812) 526-2655
Our clients have come to rely on our custom rotational molding services. In comparison to other plastic and polymer molding methods, rotational molding is extremely cost effective. The rotational molds are less expensive than either injection or blow molds and they can be easily altered. The rotational process itself is ideally suited for low volume plastics that typically involve annual volumes of 10,000 parts or less.
Rotational Molding Gives Strength and Long Lasting Stability
The plastic rotational molding process can produce hollow uniformed parts that are remarkably strong. During roto mold manufacturing, resin flows to the outer edges and corners of the rotational mold creating a finished part with
added strength and stability.
An example of this would be material handling products like recyclable containers and reusable packaging (pallets, ISO containers, JIT material delivery systems). This manufacturing technique can also provide long term cost solutions for many different products and markets that most people are unaware of. For more information and ideas, call 812-526-2655 and will be glad to answer any questions you may have!
Rotational Molding Provides the Option of Specialized Foam Filling
Another benefit we can provide is the ability of having a part foam filled with rigid polyurethane foam for added insulation and for more stability. Most coolers will use the space between the double wall area for the insertion of insulation and we have the capabilities to add that.
Also at R & R Technologies we offer a specialized technique
that can take PVC components and have them foam filled with soft polyurethane foam. These components are typically used in industrial equipment for seats, armrests, seat backs and leg bumpers. The great benefit of roto-molded vinyl components is that they usually last the life span of the equipment that they are mounted to. Please contact us for more details!

The designing of a quality mold is the first step in creating a functional, quality part. Our engineering department is able to work with many different kinds of electronic drawings like Auto Cad 2000 and Solid Works. In addition to our design assistance, RRT also can oversee tooling procurement of molds made from cast aluminum, sheet metal, machined and plate aluminum, and electro-formed nickel. If your product has a special requirement, such as needing a method of securing the part to another, or to have inlet/outlet hoses attached, we can design the correct size of metal or plastic inserts, brass or spin weld, for the part. During the production process our Quality Control department is actively involved, making sure the product you envisioned is the one you will get. There are many standards and tolerances that have to be met during the rotational process and that is why our Quality Lab measures the parts constantly to ensure they meet the specified requirements. RRT can also measure parts for temperature extremes, and for water pressure requirements. We are ISO9001-2000 registered, which ensures you that quality systems are in place and will be followed. Contact us today if you have any questions about your product design! Call 812-526-2655 The first step in manufacturing an affordable and lightweight plastic (polyethylene) item is to make a mold. This is normally done using the help of a computer software program capable of making 3 dimensional pictures. The mold is frequently made of aluminum material on the basis that the lightweight material is less demanding than other metals. Rotational molding was invented around the 1940s, but it was not broadly utilized until the advancement of better innovations that made the process quicker. Also, it helped when new plastic products and new polymer resins entered the market place and were appropriate for plastic molding. This plastic technique of production offers many advantages over other molding methods which have higher production costs and a less environmentally-friendly molding processes. Next, the techs get to work tooling the mold from the design plans, and once that is completed, it is given to a plastic maker where the rotational molding is started. The plastic maker then measures out the polymer resin ( a granular powder) and inserts it into the mold. The mold is fitted into an oven that is warmed to a suitable temperature and starts making pivotal turns, scattering the grains of polymer uniformly over the internal surface of the mold. As the aluminum rapidly heats-up, the pitch melts and keeps on coating the inside of the mold. The time the mold spends heating and spinning is vital to the quality of the item. In the past it was dependent upon the rotational mold maker to judge when a mold was ready to be removed from the oven. Nowadays, sensitive instruments measure the air temperature in the mold, which enhances the ability for better quality control. Also fans are regularly used to help the mold to cool properly. The cooling of the light weight aluminum makes the actual part pull away from the inside of the mold. This permits simple extraction of even the largest items, like water storage tanks. The part is then inspected carefully by the plastic maker and when it meets all specifications, it is shipped to the client. The rotational molding procedure is rather simple: Rotational molding is a special plastic molding process utilized primarily to produce smooth, stress-free, hollow one-piece products. Also known as rotomolding, it’s a high temperature, reduced pressure production approach that integrates heat and also bi-axial turning. Common ones used in rotational molding are: When it involves moulding or molding, there is very little distinction in the significance, apart from the spelling. Moulding is the “Old Globe” variation of the punctuation and also molding locates itself special to usage in the USA amongst plastic molders, woodworkers and also carpentry companies. The tools and equipment for the rotational process are available at affordable prices since the molds do not have to be able to survive under high-pressure which saves manufacturing costs! Also, when compared to other types of molding processes, rotational molding can be effortlessly designed and built. It increases the ability to run manufacturing at even more affordable prices. Rotational molding also allows parts to be created flexibly with steel inserts, with curves, detail company logos, and flanges. This process of rotational molding gives the capability of creating some very unique components, all at the same time. The process is also exceptionally versatile. You can change the colors of the part very easily by the addition of dyes and pigments to plastic resins anytime before they are fed into the mold. You can even add various other ingredients, like ultraviolet illumination preventions which can support the uniformity of the color in sunlight. The roto molding process can make a part with measurable wall density because all the plastic is pressed by the exact same centrifugal-forces so that the item will be evenly molded. Also this molding method can additionally develop a part with a tension free surface. It has no thin areas which could cause bursting or breaking during use.For more information on all the rotational molding services we provide, please call: 813-225-2655 and ask for Dave Hemmerling or contact us at https://www.rrtech.com/contact-us/ Our office hours are from 8:00 am to 5:00 pm, Monday through Friday.

Brad S. | Senior Buyer
“R&R has done an amazing job with my product. Before I had discovered them I was using another rotational molder that was unreliable and communicated poorly. Not only did R&R accept my product with open arms they took charge of transferring my tool, performed modifications to improve the functionality of my product, and met every deadline. Without any hesitation, I would highly recommend R&R, they have exceeded my expectations on every level and have set the bar high for customer service in the manufacturing industry.”
