rotomoulding-Lizella-Rotational molding pertains to a plastic production solution that makes hollow stress-free items. The process uses high temperatures and bi axial rotation to follow up with seamless, one piece products that have many different forms, colors and sizes. This method is also called rotomoulding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The attribute that makes this unique from other plastic manufacturing processes because no pressure is involved. It also has few contenders when it comes to the creation of large hollow items which are long-lasting and inexpensive.There is a wide range of product lines that are produced by this process including large size water tanks, automobile products, sophisticated shaped medical items, recreation equipment, toys, kayaks, industrialized equipment among many others.This is because of the flexibility in regards to design and forms that the process makes

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Lizella GA 31052, 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 rotomolding 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-Lizella-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 Georgia 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 Lizella Georgia 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 Process Components

This molding technique has been used since early times for creatingvseverl items. Egyptians as an example, utilized rotomoulding methods in the making of ceramics. The Swiss were also making use of this rotation format to generate hollow chocolate eggs. Some plastic items in the USA were made using this procedure some time between 1940 and 1950. The procedure has however taken very long to catch on because it was thought of as being a moderately slow process

1. Mould fitting.
A predetermined quantity of polymer in powder form is filled into a hollow mould. The mold is usually composeded of cast aluminium or sheet steel component. The color preferred for the finished item is pre compounded into the polymer. The most generally used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this format of plastic production.

Pre-heating of the oven follows, and it may be done by either conduction, convection or sometimes radiation. It is warmed to temperatures between 500-700F. The mold with the powdered polymer is then secured and positioned into the oven.

2. The heat and fusion procedure.
Once placed into the oven, the mould is turned on two axis so the powdered polymer melts from the heat and layers the inside if the mould. The spinning is done gradually, about 20 revolutions per min. Something that is essential at this point is the period of time the mould will spend inside the oven. If it overstays, the component will lose value and durability, generating a faulty product. If it is taken out from the oven too early, the polymer will not have flowed correctly, which develops bubbles in the finished product.

3. Mold cooling down.
When the product has sufficiently spent the right 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 shrinks a little 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 rapidly, causing bending of the product.

4. The offloading or de-molding step.
Once the product within te mold has cooled correctly, the molder handling the procedure can then remove the completed product from the mould. The procedure is repeated from the beginning, providing a number of exact product lines.
