rotocasting-Dawson-Rotational moulding pertains to a plastic manufacturing solution that generates hollow stress-free items. The technique uses high temperatures and bi axial rotation to come up with seamless, one piece items that have several forms, colors and sizes. This technique is also called rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl styles.

The attribute that makes this unique from other plastic manufacturing procedures because no pressure is involved. It also has few competitors when it comes to the creation of large hollow products which are durable and inexpensive.There is a variety of products that are developed by this process including big water tanks, automobile items, intricate molded medical products, leisure equipment, toys, canoes, industrialized equipment among many others.This is because of the flexibility in regards to type and forms that the process manufactures

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Dawson GA 31742, 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

Custom Molding-Dawson-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 Dawson 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 Components

This moulding method has been used since ancient times for creatingvseverl items. Egyptians for example, utilized roto-molding techniques in the producing of ceramics. The Swiss were also applying this rotation format to generate hollow chocolate eggs. Some plastic product lines in the USA were created using this method some time between 1940 and 1950. Considering that it was thought of to be a somewhat slow system, the process has however taken long to catch on

1. Mould prep work.
A predetermined quantity of polymer in powder form is filled into a hollow mold. The mould is usually built from cast aluminium or sheet steel substance. The coloration needed for the final goods 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 type of plastic engineering.

Preheating of the oven follows, 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 installed inside the oven.

2. The heating and fusion process.
Once inside the oven, the mold is spun on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The rotation is done slowly and gradually, about 20 rotations per min. Something that is essential at this point is the amount of time the mould will spend within the oven. If it stays to long, the material will lose stability and strength, creating a poor item. If it is taken out from the oven prematurely, the polymer will not have flowed properly, which produces bubbles in the completed product line.

3. Mold cooling down.
When the component has completely spent the right amount of time in the oven, it is then taken out for cooling. This can be done by air or water, or sometimes a mixture of both which creates a cool mist. When the product cools, it reduces somewhat for ease of removal from the mold. This is an additional step that depends upon a lot on the ideal timing, since quick cooling shrinks the material too quick, causing bending of the product.

4. The discharging or de-moulding step.
When the component inside te mold has cooled successfully, the person taking care of the procedure can then take out the finished item from the mould. The procedure is repeated from the beginning, supplying a number of exact products.
