rotomolding-West Point-Rotational moulding refers to a plastic production practice that produces hollow stress-free products. The procedure uses high temperatures and bi axial rotation to follow up with seamless, one piece items that have varying designs, colors and sizes. This method is also known as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl styles.

The function that makes this different from other plastic manufacturing procedures because no pressure is involved. It also has few competitors when it comes to the creation of sizable hollow products which are resilient and inexpensive.There is a wide variety of products that are created by this process including large size water tanks, automobile materials, sophisticated designed medical items, leisure equipment, toys, canoes, industrial equipment among many others.This is due to the versatility 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 West Point VA 23181, 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 rotocasting 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-West Point-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 Virginia 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 West Point Virginia 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 Components

This moulding process has been used since early times for creatingvseverl products. Egyptians for example, used rotocasting systems in the producing of ceramics. The Swiss were also using this rotation style to generate hollow chocolate eggs. Some plastic product lines in the USA were made utilizing this approach some time between 1940 and 1950. The system has however taken long to take affect because it was thought of to be a relatively slow process

1. Mould fitting.
A predetermined amount of polymer in powder form is loaded into a hollow mold. The mould is usually composeded of cast aluminium or sheet steel component. The coloring needed for the end 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 type of plastic manufacturing.

Pre-heating of the oven follows, and it may be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mold with the powdered polymer is then secured and installed within the oven.

2. The heating and fusion step.
Once placed into the oven, the mold is revolved on two axis so the powdered polymer melts from the heat and coats the inside if the mould. The rotation is done slowly and gradually, about 20 revolutions per min. The main thing that is vital at this moment is the amount of time the mold will spend within the oven. If it overstays, the product will lose value and strength, creating a weak item. If it is removed from the oven too early, the polymer will not have melted properly, which generates bubbles in the finished product.

3. Mould cooling down.
When the component has sufficiently spent the correct 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 material cools, it reduces somewhat for ease of extraction from the mold. This is another step that depends a lot on the correct timing, since rapid cooling reduces the material too rapidly, causing warping of the product.

4. The un-loading or de-moulding step.
When the product within te mold has cooled adequately, the molder handling the operation can then take out the completed item from the mold. The procedure is repeated from the beginning, supplying a series of identical products.
