rotomolding-Dixon-Rotational molding pertains to a plastic production procedure that produces hollow stress-free items. The method relies on high temperatures and bi axial rotation to follow up with seamless, one piece products that have several shapes, colors and sizes. This technique is also known as roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl styles.

The function that makes this unique from other plastic manufacturing methods in that no pressure is required. It also has few contenders when it comes to the creation of sizable hollow products which are durable and inexpensive.There is a wide variety of products that are created by this process including large size water tanks, automobile products, complex shaped medical items, recreation equipment, toys, canoes, industrial equipment among many others.This is due to the versatility in regards to style and forms that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Dixon IL 61021, 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-Dixon-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 Illinois 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 Dixon Illinois 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 Process Components

This moulding system has been used since earlier times for creatingvseverl items. Egyptians for instance, utilized rotational molding systems in the creating of ceramics. The Swiss were also making use of this rotation method to make hollow chocolate eggs. Some plastic products in the USA were developed using this method some time between 1940 and 1950. The system has however taken long to take affect because it was thought of as being a rather slow-moving process

1. Mold prep work.
A fixed measure of polymer in particle form is packed into a hollow mould. The mould is usually comprised of cast aluminium or sheet steel substance. The coloration chosen for the finished 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 type of plastic manufacturing.

Pre-heating of the oven starts, and it can be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then sealed and installed inside the oven.

2. The heat and fusion process.
Once inside the oven, the mould is revolved on two axis so the powdered polymer melts from the heat and overlays the inside if the mould. The turning is done gradually, about 20 revolutions per sixty seconds. One thing that is critical at this moment is the amount of time the mold will spend within the oven. If it overstays, the component will lose value and strength, making a poor product. If it is taken out from the oven prematurely, the polymer will not have flowed correctly, which creates bubbles in the finalized product line.

3. Mold cooling.
When the material has sufficiently spent the enough of time in the oven, it is then removed for cooling. This can be done by air or water, or sometimes a mixture of both which a cool mist. When the component cools, it shrinks slightly for ease of removal from the mold. This is another procedure that depends a lot on the right timing, since quick cooling reduces the material too quick, causing warping of the material.

4. The unloading or de-moulding phase.
As soon as the component within te mould has cooled successfully, the person managing the procedure can then take out the finalized item from the mould. The function is repeated from the start, giving a series of identical product lines.
