rotomolding-Kissimmee-Rotational molding refers to a plastic manufacturing technique that creates hollow stress-free product lines. The method uses high temperatures and bi axial rotation to follow up with seamless, one piece items that have many different forms, sizes and colors. This procedure is also called rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing processes in that no pressure is involved. It also has few rivals when it comes down to the creation of large size hollow products which are long lasting and inexpensive.There is a wide variety of items that are created by this process including big water tanks, automobile products, complex molded medical items, leisure equipment, toys, canoes, commercial equipment among many others.This is due to the versatility in regards to design and forms that the process develops

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Kissimmee FL 34741, 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 roto-molding 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

Custom Molding-Kissimmee-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 Florida 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 Kissimmee Florida 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 Roto-Molding Method Components

This moulding process has been used since earlier times for creatingvseverl items. Egyptians for instance, worked with rotational molding procedures in the manufacturing of ceramics. The Swiss were also using this rotation design to generate hollow chocolate eggs. Some plastic product lines in the USA were developed using this approach some time between 1940 and 1950. The process has however taken very long to take affect because it was looked at to be a very slow-moving process

1. Mould preparation.
A fixed volume of polymer in powder form is packed into a hollow mould. The mold is usually comprised of cast aluminium or sheet steel substance. The colour desired for the finished goods is pre compounded into the polymer. The most often used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this style of plastic engineering.

Preheating of the oven starts, 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 locked and installed inside the oven.

2. The heat and fusion step.
Once inside the oven, the mould is rotated on two axis so the powdered polymer melts from the heat and coats the inside if the mold. The turning is done slowly and gradually, about 20 rotations per min. Something that is critical at this moment is the period of time the mould will spend within the oven. If it stays to long, the product will lose value and durability, generating a faulty item. If it is taken out from the oven too early, the polymer will not have melted properly, which creates bubbles in the completed product.

3. Mould cooling.
When the component has sufficiently spent the correct amount of time in the oven, it is then taken out for cooling. This may be done by air or water, or sometimes a mixture of both which a cool mist. When the product cools, it shrinks slightly for ease of removal from the mold. This is another step that depends a lot on the right timing, since rapid cooling reduces the material too quickly, causing warping of the product.

4. The removing or de-moulding step.
As soon as the component within te mold has cooled properly, the molder handling the process can then remove the completed product from the mold. The process is repeated from the start, supplying a number of identical product lines.
