rotomolding-Lithia Springs-Rotational moulding pertains to a plastic manufacturing practice that generates hollow stress-free products. The procedure depends on high temperatures and bi axial rotation to come up with seamless, one piece items that have several forms, sizes and colors. This method is also known as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The component that makes this different from other plastic manufacturing techniques in that no pressure is involved. It also has few rivals when it involves the manufacture of sizable hollow products which are long-lasting and inexpensive.There is a variety of product lines that are generated by this process including big water tanks, automobile items, sophisticated shaped medical items, leisure equipment, toys, canoes, industrialized equipment among many others.This is due to the flexibility in regards to style and forms that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Lithia Springs GA 30122, 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

Custom Molding-Lithia Springs-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 Lithia Springs 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 in Detail

This moulding system has been used since earlier times for creatingvseverl items. Egyptians as an example, utilized rotocasting procedures in the manufacturing of ceramics. The Swiss were also making use of this rotation type to generate hollow chocolate eggs. Some plastic items in the USA were created utilizing this method some time between 1940 and 1950. Since it was regarded to be a somewhat slow technique, the technique has however taken long to catch on

1. Mould prep work.
A predetermined quantity of polymer in particle form is loaded into a hollow mold. The mould is usually made from cast aluminium or sheet steel material. The colour wanted for the end product is pre compounded into the polymer. The most commonly used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this format of plastic assembly.

Preheating of the oven follows, and it may 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 positioned into the oven.

2. The heating and fusion process.
Once within the oven, the mold is revolved on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The rotation is done slowly, about 20 rotations per min. Something that is critical at this point is the amount of time the mold will spend inside the oven. If it stays to long, the product will lose value and strength, generating a weak product. If it is taken out from the oven prematurely, the polymer will not have liquefied properly, which develops bubbles in the finalized product line.

3. Mould cooling down.
When the product has completely spent the correct amount of time in the oven, it is then taken out for cooling. This can be done by air or water, or sometimes a mixture of both which a cool mist. When the product cools, it shrinks a little for ease of removal from the mould. This is one more step that relies a lot on the correct timing, since quick cooling reduces the material too quick, causing bending of the material.

4. The offloading or de-moulding phase.
Once the product within te mould has cooled effectively, the molder handling the process can then remove the completed product from the mould. The procedure is repeated from the beginning, giving a series of similar product lines.
