RRM History

Rochester Rotational Molding was established in 1988 by four individuals, two of whom are currently owners and operators of the company. RRM began much of its custom molding through the IBC market. With the IBC products being 75% of the business in the early 1990's, there was a need to begin exploring other markets. One market that RRM entered was the plastic fencing market which they later withdrew from their product line.

The addition of a mold-making shop continued to increase their ability to become a full service molder. This opened the door to an increase in serviceability due to RRM's ability to take an idea from design to a finished product. Over time the ability to adapt to change and become a more market diversified molder has helped the company continue to grow and accommodate additional business as desired.

During the early 1990's the addition of a Clamshell machine continued to increase the output of production that could be achieved. As time passed, the need to develop a proprietary line of products became apparent. Currently RRM has developed a proprietary product line, and is continuing to grow as a custom molder. A large-scale shuttle machine (2 shuttles) and an FSP machine are the current machines of production. The facility accommodating 15,000 square feet on 15 acres leaves plenty of room for future growth. The development of the RRM barrier and racing product lines and the continual striving to become a full service molder leaves open the possibility for further expansion into other regions of the country.

1) How does rotational molding work?

Simply stated, rotational molding is a process by which plastic products are manufactured for a variety of applications. The process itself is a molding cycle that goes through four different phases. The first phase is referred to as the charging phase, during this phase a material or resin is charged into the mold and the mold is sealed for phase two. During the second phase, the mold is heated to a desired temperature while rotating on two specific axes. The third phase consists of a cooling stage where the mold begins to cool and the plastic begins to solidify and maintain the shape of the mold. Once the plastic resin has cooled long enough to hold its own shape, we enter into the final phase. During this final phase the mold will be reopened and the part will be de-molded producing a solid plastic product.

2) How does rotational molding compare in price to other forms of molding technologies?

Rotational molding is very competitive when it comes to cost analysis of the different molding technologies. As a comparison, the price of the tooling for rotational molding is very inexpensive compared to some other molding technologies. The prices of individual parts are very comparable to most molding procedures. However, the ability to produce large parts or hollow parts is relatively inexpensive compared to the same products in other molding technologies.

3) What is a typical cycle time for a rotational molded product?

Cycle time is a major topic in the rotational molding industry. The time of one cycle usually spans between relatively short runs of 15 minutes to a long run time of 1 hour and 30 minutes. The thickness of the product and the machine capabilities often have a major impact on the cycle time. Additional features such as cooling fans and curtains reduce the cycle time as well as advancements in machinery and equipment. Currently there is research being done to better understand and reduce cycle time in rotational molding.

4) Do you have the ability to mold all sizes and shapes of products?

RRM has the ability to mold almost any size and shape of product. With over 25 years of experience in the fabricating industry, we have found many ways to build and design molds that accommodate almost any size or shape. Our ability to mold these many sizes and shapes has been greatly enhanced by our superior mold making ability coupled with our desire and energy to "find a way". During our 23 years of experience in rotational molding we have proven that we can produce parts in many sizes and shapes.

5) What makes your safety barriers superior to others on the market?

Once again RRM prides itself on developing products that are of high quality and different in innovative content and design. The RRM barrier will not bulge or distort when filled with water ballast or sand. We also will not jeopardize our quality just to sell our barrier. During the design of our barrier we take into account that cosmetics are also a key selling point in our desired markets. We believe that we have a product that is more cosmetically pleasing than our competitors. Our product has also been designed to a higher standard of strength and integrity which we feel makes for a superior product for the end user.

6) Does your company produce tooling (molds) for custom products?

Yes, we have over 25 years of mold making and fabricating experience in the rotational molding industry. Our customer specified molds have come in a variety of sizes and shapes ranging from one gallon square boxes to 1300 gallon tanks. We have fabricated molds that are very simple and have also built molds that are very complex and intricate. The more challenging the idea the more we pride ourselves on solutions. We help to make sure the customer is getting the mold that they desire, and that meets their specifications.

7) What makes your company different from others in the rotational molding industry? 

We believe the difference RRM has from other molders in the industry is our ability to maintain the utmost integrity when working on a project for others and finding innovative content and design for our proprietary products. We know that establishing, maintaining, and building relationships in the rotational molding industry is key to being successful. Working with suppliers to maintain open communication lines has helped us to grow in the industry. Our 23 years of experience and relationship building has continued to pay off over time and work to our advantage as well as to our customer's advantage. We offer a customer oriented, face-to-face, down to earth environment where our customers feel that they aren't bogged down in the corporate structure of some of the larger manufacturers. We offer a "one stop shop" for your rotational molding needs.

8) How much water do you put in the barriers?

Most of our barriers now have fill lines. RRM recommends only filling the barriers to the
the fill line – over filling can cause bulging.
10x96x10 – Fill line is 17 gallons of water – total weight including barrier 165 lbs
24x96x16 – 7” above parting line is 50 gallons of water – total weight including barrier 467 lbs
Stackable – Fill Line is 50 gallons of water – total weight including barrier 487 lbs
Wedge – Fill Line is 70 gallons of water – total weight including barrier 653 lbs
32x72x18 – 15” above parting line is 70 gallon of water – total weight including barrier 653 lbs
42x72x24 – Fill Line is 100 gallon of water – total weight is 834 lbs + weight of barrier
42x96x24 – 13” above parting line is 130 gal. of water – total weight is 1084 lbs + weight of barrier
31x120x24 – Filling ½ full is 80 gallons of water – total weight is 667 lbs + weight of barrier
48” Cont Barrier – Fill Line is 75 gallons of water – total weight including barrier 745 lbs

9) How do you keep the barriers from freezing in the winter?

Our suggestion is using Calcium Chloride. You use 4-6 oz of Calcium Chloride per gallon 
depending on the temps outside.

10) How many barriers fit on a standard 53’ truckload?

10x96 – 432 barriers – these are always skidded – 36 barriers per skid
24x96 – 208 barriers – these are loaded loose
32x72 – 174 barriers – these are loaded loose
42x72 – 96 barriers – these are loaded loose
42x96 – 75 barriers – these are loaded loose
31x120 – 75 barriers – these are loaded loose
29” Cont Barrier – 150 barriers (approx.) – these are loaded loose
48” Cont Barrier – 78 barriers (approx.) – these are loaded loose

11) Do your barriers accept fencing?

Yes, we have a couple of barricades that accept fencing. Our 32x72 & 42x72 barriers are the
only 2 barriers we carry that do accept fencing.

12) Do any of your barriers meet TL1, TL2 or TL3?

Our 42x72x24 100# barrier has been tested and approved by the US Dept of Transportation
as a Test Level 2 Longitudinal Channelizing Device – AASHTO Manual for Assessing Safety
Hardware Test Level 2. It was stated to be acceptable as a TL2 water filled channelizer. We
do have a letter with all the testing results, if any further questions need answered regarding 
the testing.
