rotocasting-Bainbridge-Rotational moulding refers to a plastic production method 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 different forms, colors and sizes. This technique is also called rotomoulding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl types.

The benefit that makes this different from other plastic manufacturing processes because no pressure is required. It also has few competitors when it comes to the production of large hollow items which are resilient and inexpensive.There is a wide variety of items that are produced by this process including large size water tanks, automobile materials, intricate designed medical products, recreation equipment, toys, canoes, commercial equipment among many others.This is because of the versatility in regards to type 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 Bainbridge GA 31717, 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 Manufacturing-Bainbridge-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 Bainbridge 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 Rotomolding Method in Detail

This moulding system has been used since ancient times for creatingvseverl products. Egyptians for example, employed rotomoulding methods in the of ceramics. The Swiss were also working with this rotation design to make hollow chocolate eggs. Some plastic product lines in the USA were created using this technique some time between 1940 and 1950. The technique has however taken long to catch on because it was considered to be a somewhat slow-moving process

1. Mold readying.
A fixed amount of polymer in powder form is filled into a hollow mold. The mould is usually composeded of cast aluminium or sheet steel substance. The color desired for the final goods 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 type of plastic engineering.

Pre-heating of the oven starts, and it can be done by either conduction, convection or sometimes radiation. It is heated to temperatures between 500-700F. The mould with the powdered polymer is then locked and put into the oven.

2. The heat and fusion step.
Once inside the oven, the mould is rotated on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mould. The rotation is done gradually, about 20 revolutions per minute. One thing that is essential at this moment is the period of time the mould will spend within the oven. If it overstays, the material will lose stability and strength, generating a weak product. If it is removed from the oven too early, the polymer will not have flowed properly, which develops bubbles in the completed item.

3. Mold cooling.
When the product has sufficiently spent the right 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 somewhat for ease of extraction from the mould. This is one more measure that depends upon a lot on the correct timing, since rapid cooling decreases the material too fast, causing bending of the product.

4. The discharging or de-moulding phase.
When the product within te mould has cooled properly, the person taking care of the procedure can then extract the finished item from the mould. The technique is repeated from the start, making a series of exact products.
