rotomoulding-Altus-Rotational molding pertains to a plastic manufacturing method that makes hollow stress-free items. The technique uses high temperatures and bi axial rotation to follow up with seamless, one piece items that have a wide range of forms, sizes and colors. This procedure is also referred to as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing processes in that no pressure is involved. It also has few competitors when it involves the manufacture of large hollow items which are long lasting and inexpensive.There is a variety of items that are developed by this process including large water tanks, automobile items, sophisticated shaped medical items, leisure equipment, toys, kayaks, commercial equipment among many others.This is due to the flexibility in terms of type and shapes that the process makes

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Altus OK 73521, 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 rotomoulding 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 Manufacturing-Altus-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 Altus 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 Procedure Components

This moulding process has been used since ancient times for creatingvseverl items. Egyptians for example, used rotocasting techniques in the creating of ceramics. The Swiss were also employing this rotation design to create hollow chocolate eggs. Some plastic products in the USA were manufactured using this approach some time between 1940 and 1950. The procedure has however taken long to take affect because it was thought of to be a relatively slow process

1. Mould preparation.
A fixed measure of polymer in grain form is loaded into a hollow mold. The mould is usually comprised of cast aluminium or sheet steel material. The color tone needed 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 format of plastic production.

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 mould with the powdered polymer is then sealed and inserted inside the oven.

2. The heating and fusion procedure.
Once within the oven, the mould is rotated on two axis so the powdered polymer liquefies from the heat and layers the inside if the mould. The rotation is done slowly and gradually, about 20 revolutions per sixty seconds. One thing that is vital at this moment is the period of time the mold will spend within the oven. If it overstays, the component will lose stability and durability, producing a faulty product. If it is taken out from the oven prematurely, the polymer will not have melted correctly, which generates bubbles in the finalized item.

3. Mold cooling down.
When the material 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 creates a cool mist. When the component cools, it reduces somewhat for ease of extraction from the mould. This is another procedure that depends a lot on the correct timing, since quick cooling decreases the material too quickly, causing bending of the material.

4. The un-loading or de-moulding phase.
When the component inside te mold has cooled properly, the person managing the procedure can then remove the finalized item from the mold. The process is repeated from the start, providing a series of exact product lines.
