rotocasting-Wayne-Rotational molding pertains to a plastic manufacturing method that produces hollow stress-free product lines. The process relies upon high temperatures and bi axial rotation to come up with seamless, one piece items that have varying forms, colors and sizes. This method is also called rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The component that makes this unique from other plastic manufacturing techniques because no pressure is needed. It also has few contenders when it involves the manufacture of large size hollow items which are resilient and inexpensive.There is a wide range of products that are created by this process including large size water tanks, automobile items, complex molded medical products, leisure equipment, toys, canoes, industrial equipment among many others.This is due to the versatility in regards to design 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 Wayne OK 73095, 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 rotational 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

Plastic Products-Wayne-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 Wayne 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 Rotomolding Procedure in Detail

This molding system has been used since earlier times for creatingvseverl product lines. Egyptians for instance, utilized roto-molding solutions in the creating of ceramics. The Swiss were also making use of this rotation design to make hollow chocolate eggs. Some plastic items in the USA were developed using this procedure some time between 1940 and 1950. Because it was considered to be a somewhat slow system, the technique has however taken long to become popular

1. Mould prep work.
A fixed quantity of polymer in particle form is packed into a hollow mould. The mold is usually crafted from cast aluminium or sheet steel substance. The coloring intended for the final 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 style of plastic engineering.

Pre-heating of the oven follows, 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 secured and installed inside the oven.

2. The heat and fusion phase.
Once placed into the oven, the mould is rotated on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The spinning is done gradually, about 20 revolutions per minute. One thing that is critical at this moment is the period of time the mould will spend within the oven. If it overstays, the product will lose stability and strength, producing a faulty product. If it is extracted from the oven prematurely, the polymer will not have liquefied properly, which develops bubbles in the completed product line.

3. Mould cooling down.
When the component has completely spent the enough 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 reduces a little for ease of extraction from the mold. This is another step that depends upon a lot on the right timing, since rapid cooling reduces the material too quickly, causing warping of the item.

4. The unloading or de-moulding phase.
When the product inside te mold has cooled successfully, the person handling the operation can then extract the finalized item from the mold. The function is repeated from the beginning, giving a series of similar products.
