rotomoulding-Katonah-Rotational moulding refers to a plastic production solution that generates hollow stress-free products. The function depends on high temperatures and bi axial rotation to follow up with seamless, one piece products that have various shapes, colors and sizes. This method is also known as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The attribute that makes this different from other plastic manufacturing procedures because no pressure is required. It also has few contenders when it comes down to the creation of large hollow items which are resilient and inexpensive.There is a variety of products that are created by this process including large size water tanks, automobile items, complex molded medical items, leisure equipment, toys, kayaks, industrial equipment among many others.This is due to the flexibility in regards to design and forms that the process produces

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Katonah NY 10536, 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-Katonah-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 New York 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 Katonah New York 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 Method Components

This moulding method has been used since earlier times for creatingvseverl products. Egyptians for example, worked with rotocasting methods in the producing of ceramics. The Swiss were also utilizing this rotation type to make hollow chocolate eggs. Some plastic product lines in the USA were developed utilizing this technique some time between 1940 and 1950. The technique has however taken very long to take affect because it was considered as being a pretty slow process

1. Mould prep work.
A predetermined amount of polymer in grain form is packed into a hollow mould. The mold is usually made from cast aluminium or sheet steel component. The coloring chosen for the final product is pre compounded into the polymer. The most commonly used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this format of plastic manufacturing.

Pre-heating 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 mold with the powdered polymer is then secured and installed within the oven.

2. The heating and fusion process.
Once within the oven, the mould is revolved on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The spinning is done slowly and gradually, about 20 revolutions per min. Something that is crucial at this moment is the period of time the mold will spend inside the oven. If it stays to long, the product will lose stability and durability, producing a weak item. If it is taken out from the oven prematurely, the polymer will not have melted properly, which creates bubbles in the finished product line.

3. Mold 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 material cools, it reduces somewhat for ease of removal from the mold. This is an additional measure that depends upon a lot on the correct timing, since quick cooling reduces the material too fast, causing warping of the material.

4. The un-loading or de-molding step.
As soon as the product within te mould has cooled successfully, the molder handling the procedure can then extract the finished item from the mold. The technique is repeated from the start, supplying a series of identical items.
