rotomoulding-Gaffney-Rotational molding pertains to a plastic production practice that makes hollow stress-free items. The technique relies upon high temperatures and bi axial rotation to come up with seamless, one piece objects that have various designs, colors and sizes. This technique is also known as rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The benefit that makes this unique from other plastic manufacturing procedures in that no pressure is required. It also has few competitors when it involves the production of large size hollow products which are durable and inexpensive.There is a wide range of product lines that are produced by this process including large size water tanks, automobile materials, sophisticated molded medical items, recreation equipment, toys, kayaks, industrialized equipment among many others.This is because of the versatility in regards to type 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 Gaffney SC 29340, 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 Molded-Gaffney-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 South Carolina 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 Gaffney South Carolina 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 Procedure Components

This molding method has been used since ancient times for creatingvseverl items. Egyptians for instance, used rotational molding methods in the of ceramics. The Swiss were also employing this rotation type to make hollow chocolate eggs. Some plastic products in the USA were created utilizing this method some time between 1940 and 1950. The process has however taken very long to catch on because it was looked at to be a moderately slow process

1. Mould prep work.
A predetermined volume of polymer in powder form is filled into a hollow mould. The mould is usually comprised of cast aluminium or sheet steel component. The color tone wanted for the end product 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 design of plastic assembly.

Preheating 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 secured and inserted into the oven.

2. The heating up and fusion procedure.
Once placed into the oven, the mould is spun on two axis so the powdered polymer melts from the heat and coats the inside if the mould. The turning is done slowly and gradually, about 20 rotations per minute. The main thing that is essential at this point is the period of time the mould will spend within the oven. If it overstays, the component will lose value and strength, generating a weak item. If it is extracted from the oven prematurely, the polymer will not have melted correctly, which develops bubbles in the finished item.

3. Mold cooling down.
When the material has completely 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 a cool mist. When the component cools, it reduces somewhat for ease of extraction from the mould. This is yet another measure that depends a lot on the right timing, since quick cooling reduces the material too fast, causing warping of the item.

4. The discharging or de-molding phase.
As soon as the product within te mould has cooled successfully, the person managing the operation can then extract the finished product from the mold. The function is repeated from the beginning, giving a series of similar products.
