rotational molding-Ballard-Rotational molding refers to a plastic manufacturing technique that makes hollow stress-free products. The procedure relies upon high temperatures and bi axial rotation to come up with seamless, one piece products that have varying shapes, sizes and colors. This technique 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 techniques that no pressure is called for. It also has few competitors when it comes to the manufacture of sizable hollow products which are durable and inexpensive.There is a variety of products that are developed by this process including large water tanks, automobile items, sophisticated molded medical products, leisure equipment, toys, kayaks, industrialized equipment among many others.This is because of the versatility in terms of design 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 Ballard WV 24918, 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 rotocasting 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-Ballard-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 West Virginia 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 Ballard West Virginia 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 Process Components

This molding technique has been used since early times for creatingvseverl products. Egyptians as an example, used rotocasting methods in the making of ceramics. The Swiss were also utilizing this rotation method to make hollow chocolate eggs. Some plastic items in the USA were made utilizing this technique some time between 1940 and 1950. The procedure has however taken long to take affect because it was thought of as being a relatively slow-moving process

1. Mould prep work.
A fixed volume of polymer in powder form is filled into a hollow mold. The mould is usually composeded of cast aluminium or sheet steel component. The colour needed for the finished 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 type of plastic production.

Pre-heating of the oven starts, and it may 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 locked and put within the oven.

2. The heat and fusion phase.
Once inside the oven, the mold is spun on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The turning is done slowly and gradually, about 20 rotations per sixty seconds. Something that is important at this point is the amount of time the mould will spend inside the oven. If it overstays, the component will lose value and durability, producing a poor item. If it is taken out from the oven prematurely, the polymer will not have melted properly, which generates bubbles in the finalized product.

3. Mold cooling down.
When the component has sufficiently spent the correct amount 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 creates a cool mist. When the material cools, it reduces somewhat for ease of removal from the mold. This is one more step that relies a lot on the ideal timing, since rapid cooling decreases the material too rapidly, causing warping of the material.

4. The removing or de-moulding step.
As soon as the component inside te mold has cooled properly, the person handling the process can then remove the completed product from the mould. The procedure is repeated from the start, supplying a series of exact products.
