rotocasting-Fountain Inn-Rotational molding pertains to a plastic production practice that produces hollow stress-free product lines. The method utilizes high temperatures and bi axial rotation to follow up with seamless, one piece items that have various shapes, colors and sizes. This procedure is also called rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The feature that makes this unique from other plastic manufacturing processes in that no pressure is required. It also has few competitors when it comes to the manufacture of sizable hollow items which are durable and inexpensive.There is a variety of product lines that are developed by this process including large size water tanks, automobile materials, intricate molded medical items, recreation equipment, toys, canoes, industrialized equipment among many others.This is due to the versatility in terms of 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 Fountain Inn SC 29644, 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 Molded-Fountain Inn-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 Fountain Inn 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 Rotomoulding Method Components

This molding system has been used since ancient times for creatingvseverl products. Egyptians as an example, employed rotomoulding systems in the creating of ceramics. The Swiss were also using this rotation design to create hollow chocolate eggs. Some plastic items in the USA were created utilizing this procedure some time between 1940 and 1950. Given that it was considered to be a somewhat slow system, the approach has however taken long to become popular

1. Mould preparation.
A fixed amount of polymer in powder form is packed into a hollow mold. The mold is usually crafted from cast aluminium or sheet steel component. The coloring preferred for the end product 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 design of plastic manufacturing.

Preheating of the oven follows, 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 within the oven.

2. The heating and fusion step.
Once inside the oven, the mould is revolved on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mold. The spinning is done slowly, about 20 rotations per min. The main thing that is crucial at this moment is the amount of time the mould will spend within the oven. If it overstays, the material will lose value and durability, making a poor item. If it is removed from the oven prematurely, the polymer will not have flowed properly, which produces bubbles in the finished product line.

3. Mold cooling down.
When the component has completely spent the right 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 a little for ease of removal from the mould. This is another measure that relies a lot on the right timing, since rapid cooling reduces the material too rapidly, causing bending of the product.

4. The discharging or de-molding step.
As soon as the component within te mould has cooled correctly, the molder managing the procedure can then remove the finished item from the mould. The function is repeated from the beginning, making a series of identical items.
