roto-molding-Norcross-Rotational molding refers to a plastic production method that generates hollow stress-free items. The process relies upon high temperatures and bi axial rotation to come up with seamless, one piece items that have different shapes, colors and sizes. This method is also called roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl styles.

The feature that makes this unique from other plastic manufacturing processes because no pressure is required. It also has few contenders when it comes to the production of sizable hollow products which are resilient and inexpensive.There is a wide range of items that are generated by this process including large size water tanks, automobile materials, intricate designed medical items, recreation equipment, toys, kayaks, industrialized equipment among many others.This is because of the flexibility in terms of design and forms that the process develops

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Norcross GA 30003, 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

Custom Molding-Norcross-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 Norcross 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 Rotomoulding Procedure Components

This molding method has been used since earlier times for creatingvseverl items. Egyptians for instance, worked with rotational molding techniques in the making of ceramics. The Swiss were also applying this rotation format to create hollow chocolate eggs. Some plastic items in the USA were created using this method some time between 1940 and 1950. The technique has however taken long to catch on because it was thought of to be a rather slow process

1. Mold prep work.
A predetermined quantity of polymer in powder form is packed into a hollow mold. The mold is usually crafted from cast aluminium or sheet steel component. The colour intended 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 format of plastic production.

Pre-heating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is warmed to temperatures between 500-700F. The mold with the powdered polymer is then sealed and positioned inside the oven.

2. The heating and fusion process.
Once inside the oven, the mould is spun on two axis so the powdered polymer melts from the heat and overlays the inside if the mould. The rotation is done gradually, about 20 spins per minute. The main thing that is vital at this point is the amount of time the mould will spend inside the oven. If it overstays, the product will lose value and durability, generating a poor item. If it is extracted from the oven prematurely, the polymer will not have melted properly, which creates bubbles in the finalized item.

3. Mold cooling.
When the material has completely spent the right 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 material cools, it shrinks slightly for ease of extraction from the mold. This is an additional procedure that depends a lot on the right timing, since quick cooling reduces the material too fast, causing warping of the product.

4. The offloading or de-molding step.
When the component inside te mould has cooled successfully, the person taking care of the procedure can then remove the completed item from the mould. The procedure is repeated from the beginning, providing a series of similar products.
