rotomolding-Choctaw-Rotational moulding pertains to a plastic manufacturing method that creates hollow stress-free product lines. The method utilizes high temperatures and bi axial rotation to come up with seamless, one piece products that have many different forms, colors and sizes. This procedure is also called rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl types.

The function that makes this different from other plastic manufacturing processes because no pressure is called for. It also has few competitors when it involves the creation of large size hollow products which are long-lasting and inexpensive.There is a wide range of items that are generated by this process including large size water tanks, automobile materials, sophisticated molded medical products, recreation equipment, toys, kayaks, commercial equipment among many others.This is because of the flexibility in regards to type 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 Choctaw OK 73020, 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-Choctaw-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 Oklahoma 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 Choctaw Oklahoma 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 moulding system has been used since early times for creatingvseverl products. Egyptians for instance, used rotomoulding techniques in the making of ceramics. The Swiss were also working with this rotation style to make hollow chocolate eggs. Some plastic products in the USA were manufactured utilizing this method some time between 1940 and 1950. Given that it was thought of to be a rather slow-moving procedure, the method has however taken long to catch on

1. Mould preparation.
A predetermined measure of polymer in powder form is loaded into a hollow mold. The mould is usually built from cast aluminium or sheet steel component. The color tone needed 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 type of plastic production.

Pre-heating of the oven starts, 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 within the oven.

2. The heating and fusion procedure.
Once within the oven, the mold is rotated on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The rotation is done gradually, about 20 revolutions per minute. The main thing that is essential at this point is the amount of time the mold will spend inside the oven. If it stays to long, the material will lose value and strength, creating a faulty item. If it is taken out from the oven prematurely, the polymer will not have melted properly, which generates bubbles in the completed item.

3. Mold cooling down.
When the component has completely spent the right amount of time in the oven, it is then removed for cooling. This can be done by air or water, or sometimes a mixture of both which creates a cool mist. When the material cools, it reduces somewhat for ease of removal from the mould. This is an additional step that relies a lot on the right timing, since rapid cooling decreases the material too rapidly, causing warping of the material.

4. The discharging or de-molding phase.
As soon as the material inside te mould has cooled effectively, the molder handling the operation can then remove the finalized product from the mould. The function is repeated from the beginning, supplying a number of similar products.
