roto-molding-Barnesville-Rotational molding refers to a plastic manufacturing technique that generates hollow stress-free products. The method relies upon high temperatures and bi axial rotation to come up with seamless, one piece products that have a variety of designs, sizes and colors. This method is also known as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The function that makes this different from other plastic manufacturing techniques that no pressure is involved. It also has few competitors when it comes to the creation of large hollow products which are long-lasting and inexpensive.There is a variety of items that are produced by this process including large water tanks, automobile products, sophisticated designed medical products, recreation equipment, toys, canoes, industrial equipment among many others.This is because of the flexibility in regards to design 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 Barnesville GA 30204, 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 Molding-Barnesville-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 Georgia 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 Barnesville Georgia 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 in Detail

This molding procedure has been used since early times for creatingvseverl products. Egyptians for instance, worked with rotational molding systems in the producing of ceramics. The Swiss were also employing this rotation technique to create hollow chocolate eggs. Some plastic products in the USA were manufactured utilizing this approach some time between 1940 and 1950. The procedure has however taken long to take affect because it was looked at as being a somewhat slow-moving process

1. Mold fitting.
A fixed quantity of polymer in grain form is packed into a hollow mold. The mold is usually made from cast aluminium or sheet steel component. The coloring wanted for the final item is pre compounded into the polymer. The most typically used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this type of plastic production.

Preheating of the oven follows, and it may 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 sealed and inserted within the oven.

2. The heating up and fusion process.
Once placed into the oven, the mould is spun on two axis so the powdered polymer melts from the heat and layers the inside if the mould. The rotation is done gradually, about 20 rotations per min. One thing that is crucial at this moment is the amount of time the mould will spend within the oven. If it overstays, the product will lose stability and durability, making a faulty item. If it is taken out from the oven prematurely, the polymer will not have flowed correctly, which produces bubbles in the finalized item.

3. Mould cooling.
When the component has completely spent the correct 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 a cool mist. When the product cools, it reduces slightly for ease of extraction from the mould. This is an additional procedure that relies a lot on the right timing, since rapid cooling reduces the material too quick, causing warping of the material.

4. The un-loading or de-moulding phase.
As soon as the material inside te mold has cooled correctly, the person handling the procedure can then take out the finished product from the mould. The process is repeated from the beginning, supplying a series of similar product lines.
