rotational molding-Lithonia-Rotational molding refers to a plastic production solution that generates hollow stress-free items. The method depends on high temperatures and bi axial rotation to come up with seamless, one piece products that have several forms, sizes and colors. This procedure is also known as rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The feature that makes this different from other plastic manufacturing processes in that no pressure is required. It also has few rivals when it comes to the production of large hollow products which are durable and inexpensive.There is a variety of items that are created by this process including large size water tanks, automobile products, sophisticated designed medical items, recreation equipment, toys, kayaks, industrial equipment among many others.This is because of the versatility 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 Lithonia GA 30038, 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

Plastic Manufacturing-Lithonia-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 Lithonia 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 Roto-Molding Process Components

This molding technique has been used since earlier times for creatingvseverl products. Egyptians for instance, employed rotocasting solutions in the manufacturing of ceramics. The Swiss were also applying this rotation type to generate hollow chocolate eggs. Some plastic product lines in the USA were made using this technique some time between 1940 and 1950. Considering that it was considered to be a basically slow approach, the technique has however taken long to catch on

1. Mold fitting.
A fixed amount of polymer in powder form is loaded into a hollow mould. The mould is usually built from cast aluminium or sheet steel substance. The color intended 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 engineering.

Pre-heating of the oven starts, 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 secured and put within the oven.

2. The heating and fusion step.
Once inside the oven, the mould is spun on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mould. The spinning is done slowly, about 20 rotations per minute. The main thing that is vital at this point is the amount of time the mould will spend within the oven. If it stays to long, the component will lose value and durability, creating a weak product. If it is extracted from the oven prematurely, the polymer will not have flowed properly, which produces bubbles in the completed product line.

3. Mould cooling.
When the material has sufficiently spent the right amount of time in the oven, it is then extracted 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 shrinks a little for ease of removal from the mold. This is one more measure that depends a lot on the right timing, since rapid cooling decreases the material too fast, causing bending of the product.

4. The discharging or de-moulding phase.
When the material within te mold has cooled properly, the molder taking care of the procedure can then extract the finalized product from the mold. The process is repeated from the start, giving a series of identical items.
