rotocasting-Round o-Rotational molding pertains to a plastic manufacturing procedure that produces hollow stress-free product lines. The process relies on high temperatures and bi axial rotation to follow up with seamless, one piece products that have different shapes, sizes and colors. This method is also referred to as roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl types.

The component that makes this different from other plastic manufacturing procedures that no pressure is required. It also has few competitors when it pertains to the production of large size hollow items which are resilient and inexpensive.There is a wide range of products that are generated by this process including big water tanks, automobile items, sophisticated designed medical products, leisure equipment, toys, canoes, commercial equipment among many others.This is due to the versatility in regards to style and shapes that the process develops

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Round o SC 29474, 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 Products-Round o-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 South Carolina 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 Round o South Carolina 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 procedure has been used since early times for creatingvseverl items. Egyptians for example, used roto-molding systems in the making of ceramics. The Swiss were also using this rotation format to make hollow chocolate eggs. Some plastic product lines in the USA were developed using this approach some time between 1940 and 1950. The procedure has however taken long to catch on because it was looked at as being a relatively slow-moving process

1. Mould preparation.
A fixed quantity of polymer in particle form is loaded into a hollow mould. The mould is usually constructed from cast aluminium or sheet steel material. The colour desired for the final 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 assembly.

Preheating of the oven starts, and it can 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 sealed and installed inside the oven.

2. The heating up and fusion procedure.
Once within the oven, the mold is turned on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The rotation is done gradually, about 20 revolutions per sixty seconds. One thing that is vital at this point is the period of time the mould will spend inside the oven. If it stays to long, the product will lose value and durability, making a poor product. If it is extracted from the oven too early, the polymer will not have melted correctly, which creates bubbles in the finished product line.

3. Mould cooling down.
When the material has completely 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 creates a cool mist. When the product cools, it shrinks somewhat for ease of removal from the mould. This is yet another procedure that depends a lot on the correct timing, since quick cooling decreases the material too quick, causing bending of the item.

4. The removing or de-moulding phase.
Once the material inside te mold has cooled effectively, the person handling the procedure can then take out the finalized item from the mould. The process is repeated from the start, supplying a series of similar product lines.
