rotomoulding-Lewisport-Rotational molding pertains to a plastic manufacturing technique that creates hollow stress-free product lines. The function uses high temperatures and bi axial rotation to come up with seamless, one piece items that have a variety of shapes, colors and sizes. This method is also referred to as roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The attribute that makes this unique from other plastic manufacturing procedures because no pressure is involved. It also has few rivals when it comes down to the creation of large hollow items which are long lasting and inexpensive.There is a wide variety of items that are created by this process including large size water tanks, automobile products, sophisticated designed medical items, recreation equipment, toys, canoes, industrialized equipment among many others.This is because of the versatility in terms of style and shapes that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Lewisport KY 42351, it is a cheaper way of making plastics. This is because apart from the fact that no pressure is required, the cost of mold preparation is low.
  • A wide array of design options.
    There is no limit to the kind of design one may want to create. The rotomoulding process therefore allows for the manufacturing of products that have complex shapes for different purposes.
  • Size.
    The process provides room for the manufacturing of products of any size, large or small. As mentioned earlier, it has few competitors when it comes to the making of large tanks at low costs.
  • Low risk.
    Due to the low costs of creating a mould, the process allows for test runs before one can decide whether to do mass production. It therefore minimizes the risk of losing a lot of investment.
  • Durable products.
    The process allows for even coating of the mould with the heated polymer, giving the product a wall with uniform thickness. It also gives the option of double coating for increased durability. Sometimes metal inserts are placed inside the mould to further strengthen the product.
  • Environmentally friendly.
    There is no waste that could have a negative impact on the environment because the products that cannot be used are reground and reused as polymer.

Examples of Products Made by Rotational Molding

Plastic Molding-Lewisport-Rotocasting is a very versatile process, making it possible to create a variety of products for different industries.

  • Agricultural industry– From cattle feeders, water troughs, spray tanks etc.
  • Automotive industry– Filler tubes, dash boards, arm rests, sun visors, air conditioner duct work etc.
  • Furniture– We have plastic cabinets, chairs and tables made from this form of moulding.

There are numerous Kentucky plastic products also that have been made for the marine industry, lighting, waste storage and transportation, kayaks etc.

Few Disadvantages – There are nominal disadvantages that have been associated with rotocasting. For instance:

  • – The process is relatively slow when compared to injection moulding.
  • – There is a limitation when it comes to the type of raw material you can use. Only poly based and nylon polymers can be used.
  • – The process comes with an increased cost because the polymer has to be ground to powder form before use.
    These limitations are often overlooked considering that the process is still relatively cheap and offers more in terms of variety when it comes to the finished range of products.

Remember – There are new developments and discoveries that are being made as the world of plastic manufacturing in Lewisport Kentucky continuously. For instance, tests are being done to see whether there are other materials that can be used for this process. But so far, rotomoulding offers a good option for the production of a wide range of inexpensive plastic products.

The Rotomoulding Process in Detail

This moulding technique has been used since ancient times for creatingvseverl products. Egyptians as an example, employed rotomoulding methods in the producing of ceramics. The Swiss were also utilizing this rotation style to generate hollow chocolate eggs. Some plastic products in the USA were made using this approach some time between 1940 and 1950. Since it was thought of to be a rather slow-moving process, the approach has however taken long to catch on

1. Mould readying.
A fixed measure of polymer in particle form is packed into a hollow mould. The mould is usually made of cast aluminium or sheet steel component. The coloration preferred for the end item is pre compounded into the polymer. The most typically used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this type of plastic engineering.

Preheating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then sealed and placed within the oven.

2. The heating and fusion step.
Once placed into the oven, the mold is turned on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The turning is done gradually, about 20 revolutions per sixty seconds. The main thing that is important at this moment is the amount of time the mould will spend within the oven. If it overstays, the component will lose stability and strength, generating a faulty product. If it is removed from the oven too early, the polymer will not have flowed properly, which generates bubbles in the finished product.

3. Mould cooling.
When the component has sufficiently spent the correct amount of time in the oven, it is then extracted for cooling. This can be done by air or water, or sometimes a mixture of both which generates a cool mist. When the product cools, it reduces a little for ease of extraction from the mold. This is an additional procedure that depends upon a lot on the ideal timing, since rapid cooling reduces the material too rapidly, causing warping of the product.

4. The un-loading or de-molding step.
As soon as the product within te mould has cooled effectively, the person managing the operation can then remove the completed item from the mould. The procedure is repeated from the start, supplying a series of similar products.
