rotomolding-Inez-Rotational moulding pertains to a plastic manufacturing practice that produces hollow stress-free product lines. The technique relies on high temperatures and bi axial rotation to come up with seamless, one piece items that have a wide range of forms, colors and sizes. This method is also referred to as roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The function that makes this different from other plastic manufacturing procedures that no pressure is called for. It also has few rivals when it comes to the manufacture of large size hollow items which are durable and inexpensive.There is a variety of products that are created by this process including big water tanks, automobile items, complex designed medical products, recreation equipment, toys, kayaks, commercial equipment among many others.This is because of the flexibility in terms of 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 Inez KY 41224, 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-Inez-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 Kentucky 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 Inez Kentucky 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 moulding process has been used since ancient times for creatingvseverl items. Egyptians for instance, worked with rotocasting systems in the making of ceramics. The Swiss were also making use of this rotation style to make hollow chocolate eggs. Some plastic items in the USA were developed using this technique some time between 1940 and 1950. The technique has however taken long to catch on because it was thought of to be a pretty slow process

1. Mould prep work.
A fixed amount of polymer in grain form is packed into a hollow mold. The mould is usually built from cast aluminium or sheet steel material. The colour needed for the final 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 format of plastic production.

Preheating of the oven starts, 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 secured and positioned within the oven.

2. The heat and fusion procedure.
Once placed into the oven, the mold is rotated on two axis so the powdered polymer melts from the heat and overlays the inside if the mould. The turning is done slowly and gradually, about 20 revolutions per sixty seconds. One thing that is important at this moment is the amount of time the mold will spend within the oven. If it stays to long, the product will lose value and strength, creating a faulty item. If it is removed from the oven too early, the polymer will not have melted correctly, which develops bubbles in the finalized item.

3. Mold cooling down.
When the component has completely spent the enough of time in the oven, it is then removed for cooling. This may be done by air or water, or sometimes a mixture of both which generates a cool mist. When the product cools, it shrinks somewhat for ease of removal from the mold. This is another procedure that relies a lot on the right timing, since rapid cooling decreases the material too rapidly, causing warping of the material.

4. The un-loading or de-moulding step.
Once the component inside te mold has cooled properly, the molder managing the process can then remove the finished item from the mould. The procedure is repeated from the start, supplying a series of similar product lines.
