rotational molding-Lamont-Rotational moulding refers to a plastic manufacturing solution that generates hollow stress-free product lines. The function relies upon high temperatures and bi axial rotation to come up with seamless, one piece items that have several designs, colors and sizes. This technique is also referred to as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl styles.

The component that makes this unique from other plastic manufacturing methods in that no pressure is involved. It also has few contenders when it comes to the production of sizable hollow products which are long-lasting and inexpensive.There is a wide variety of product lines that are generated by this process including big water tanks, automobile products, sophisticated designed medical products, leisure equipment, toys, kayaks, industrialized equipment among many others.This is due to the flexibility in regards to style and shapes that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Lamont OK 74643, 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 Molding-Lamont-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 Lamont 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 Method in Detail

This molding technique has been used since ancient times for creatingvseverl product lines. Egyptians as an example, utilized rotocasting techniques in the creating of ceramics. The Swiss were also working with this rotation design to make hollow chocolate eggs. Some plastic items in the USA were made using this approach some time between 1940 and 1950. The system has however taken long to catch on because it was thought of as being a relatively slow-moving process

1. Mould preparation.
A predetermined volume of polymer in particle form is filled into a hollow mould. The mold is usually composeded of cast aluminium or sheet steel substance. The color needed for the end product 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 design of plastic manufacturing.

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

2. The heat and fusion step.
Once inside the oven, the mold is rotated on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The rotation is done gradually, about 20 revolutions per sixty seconds. The main thing that is important at this point is the amount of time the mold will spend inside the oven. If it stays to long, the material will lose stability and strength, making a weak item. If it is removed from the oven too early, the polymer will not have flowed properly, which develops bubbles in the finished product.

3. Mold cooling down.
When the product has sufficiently spent the right amount of time in the oven, it is then extracted 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 an additional step that depends upon a lot on the correct timing, since quick cooling decreases the material too quickly, causing warping of the item.

4. The un-loading or de-molding step.
Once the material inside te mold has cooled effectively, the person handling the procedure can then remove the finalized product from the mould. The function is repeated from the start, giving a series of identical products.
