Midwest Rotational Molding
R&R Technologies LLC | Rotational Molding Service Provider
R&R Technologies LLC is a United States plastic rotational molding service provider and member of the Association of Rotational Molders International. We lie at 7560 East County Line Road, Edinburgh, IN 46124, Ph: (812) 526-2655
Rotational molding is exceptionally cost-reliable compared to other plastic and polymer molding approaches. In addition, the rotational molds are less expensive than either injection or blow molds, and they can be easily altered.
Rotational Molding Produces Strength and Long Lasting Stability
The plastic rotational molding procedure can produce hollow uniformed parts that are remarkably strong. Throughout roto mold manufacturing, the resin flows to the rotational mold's outer edges and corners, creating a completed part with rotomolded tanks that included strength and stability.
An example would be material handling items like recyclable containers and recyclable product packaging (pallets, ISO containers, JIT material delivery systems). This production strategy can also provide long-term expense solutions for various products and markets that most people are uninformed of. To find out more and ideas, call 812-526-2655, and we will be glad to address the questions you need to be answered!
Rotational Molding Has the Option of Specialized Foam Filling
Another advantage we can supply is having a part foam filled with rigid polyurethane foam for included insulation and more stability. Many coolers will use the area in between the double wall area for the insertion of insulation, and we can add that.
At R & R Technologies, we specialize in form-filled rotational molding that can take PVC parts and foam fill them with soft polyurethane foam. These components are usually utilized in commercial seats, armrests, seatbacks, and leg bumpers.
Quality Service Means Satisfied Customers
" R&R Technologies has been our rotational molding supplier for several years and consistently supplies parts that fulfill our requirements, and parts get delivered on time. If it is new items or taking on the extra volume of existing items, R&R reacts in a fast way and meets our requirements."
Brad S.|Senior Buyer
" R&R has done a remarkable job with my product. Before I had discovered them, I was utilizing another rotational molder that was unreliable and interacted inadequately. Not just did R&R accept my product with open arms, they took charge of moving my tool, performed modifications to improve the performance of my item, and satisfied every due date. With no hesitation, I would extremely advise R&R; they have far exceeded my requirements on every part and have set the bar high for customer service in the production market."

If You Have a Drawing, an Idea, or a Current Part
R&R Technologies LLC, we can assist make your completed plastic part from start to finish. Our engineering staff has years of experience in rotational molding strategies and design.
Creating a quality mold is the first step in producing a practical, quality part. Next, our engineering department can work with electronic illustrations like Auto Cad 2000 and Solid Works.
In addition to our design assistance, RRT can provide tooling for the molds for your product has a unique requirement, such as needing a technique of connecting the part to another or to have inlet/outlet hoses attached. In addition, we can create the proper metal or plastic inserts, brass or spin weld, for the part.
Our Quality Control department is actively involved throughout the production process, making sure the product you pictured is the one you will get. Numerous standards and tolerances have to be fulfilled throughout the rotational procedure. Our Quality Lab measures the parts constantly to ensure they meet the specified requirements. RRT can likewise measure parts for temperature extremes and water pressure requirements.
Advantages of Rotational Molding
- Parts initially assembled from several pieces can be molded as one piece.
- Companies can produce routine, stress-free wall surface thickness and strong corners outdoors.
- Engineers can pick the best plastics and additives needed, making the elements climate-resistant and flame retardant.
- Plastic designers have the alternative of adding inserts, handles, threads, and ultra-fine surface area details.
- Huge or small parts can be produced.
- Also, since there is no inner core, simple changes can be added to pre-existing molds making the procedure extra affordable
- Plastic arts are formed with heat and rotation, unlike the injection molding procedure, which needs high pressure.
- Material and manufacturing costs are lower since lighter materials can replace heavier and more costly products.
- Companies can get their plastic product rapidly from prototyping and into the marketplace faster.
The Rotational Molding Process
The first step in making an economical and lightweight plastic (polyethylene) item is to make a mold. This is generally done utilizing a computer software application that is efficient in making three-dimensional photos. The mold is frequently made from aluminum material because the lightweight product is less demanding than other metals. Rotational molding was created around the 1940s, but it was not broadly used until the improvement of better innovations that made the procedure quicker. Also, it helped when new plastic items and new polymer resins went into the marketplace location and were appropriate for plastic molding. This plastic production technique provides numerous benefits over other molding approaches, with more significant production expenses and less environmentally-friendly molding procedures.
Next, the techs get to work tooling the mold from the design plans, and when that is finished, it is provided to a plastic maker where the rotational molding is begun. The plastic maker then rations the polymer resin (a granular powder) and inserts it into the mold. The mold is suited to an oven that is warmed to an ideal temperature and starts making critical turns, spreading the grains of polymer evenly over the internal surface of the mold. As the aluminum rapidly heats up, the pitch melts and continues coating the within the mold. The time the mold spends heating and spinning is essential to the quality of the product. In the past, it depended on the rotational mold maker to judge when a mold was ready to be eliminated from the oven.
Nowadays, delicate instruments measure the air temperature level in the mold, which improves the ability for better quality control. The cooling of the lightweight aluminum makes the actual part pull away from the inside of the mold.
