CUSTOM ROTATIONAL MOLDING SERVICE
Rotomolding, what is it?
Rotational molding is a process for making hollow plastic parts. A measured amount of powdered plastic is placed inside a mold. The mold is closed and goes into an oven. The mold is rotated such that the powder contacts all the interior surfaces. Heat melts the powder into a layer that covers the inside of the mold. The mold is removed from the oven, cooled and opened. The molded part is then removed.
What kind of parts and products are made by rotomolding?
Typical products include containers as well as material handling, industrial and recreational equipment. The process produces a seamless hollow piece. Small parts can weigh less than a pound. Larger parts weigh up to several hundred pounds. The wall thickness can be controlled. Many types of plastics can be rotomolded, most often polyethylene, in a wide range of colors.
How are the molds made?
Fabricated molds are made from metal sheets and shapes, usually steel or aluminum. The metal is cut, bent, fitted and welded. Casting aluminum from a wood pattern can make molds with more complex curves and shapes. CNC milling yields a precise and detailed mold. Sometimes the best solution is to combine more than one of these methods.
How are the molds designed?
The customer can provide the finished design or work with our design team to create a solution. We can work from your sketches and specifications. We use Solidworks 3D modeling software to illustrate and rework the design to your satisfaction.
Does Dixie Poly Drum Make molds?
Yes, we make fabricated molds. We commission the making of cast or milled molds through specialty tooling shops. We also run molds the customer had made elsewhere.
What features can be added after the molding process?
Secondary operations include routing, drilling and cutting. Hardware like valves, brackets, hinges and wheels are added.
How well does the product last?
Linear polyethylene is the material we use the most. It has excellent strength, durability and toughness. All of our materials include UV inhibitors making them suitable for extended outdoor use. Our hardware and fittings have a proven record of excellent service.
How much does it cost?
Fabricated molds cost as little as $1500 and up. Cast or milled molds are several thousand dollars and up. The customer usually pays the mold cost up front and retains ownership of the mold. The cost of molding individual parts depends on size, complexity and the number ordered. Molding a twenty pound part would typically range from $35 to $70. an eighty-pound part might range from $150 to $300.
How do I get a quote?
Provide us with your requirements and we can give you a preliminary estimate. When the design is finalized, we will provide a quote for the mold. We will also provide a per piece quote based on the number you expect to order. There is no charge for us to provide a quote. If there is a fee for our design work we will let you know first, before any charges are incurred.
