rotomoulding-South Lebanon-Rotational moulding pertains to a plastic production practice that generates hollow stress-free product lines. The process relies upon high temperatures and bi axial rotation to follow up with seamless, one piece products that have a wide range of designs, sizes and colors. This procedure is also called rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The component that makes this different from other plastic manufacturing procedures in that no pressure is involved. It also has few contenders when it comes to the manufacture of large size hollow products which are long-lasting and inexpensive.There is a wide range of products that are created by this process including large size water tanks, automobile items, intricate designed medical products, leisure equipment, toys, canoes, industrial equipment among many others.This is due to the flexibility in regards to design and shapes that the process manufactures

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in South Lebanon OH 45065, 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

Plastic Products-South Lebanon-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 Ohio 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 South Lebanon Ohio 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 Method Components

This moulding operation has been used since early times for creatingvseverl product lines. Egyptians as an example, utilized rotational molding systems in the making of ceramics. The Swiss were also making use of this rotation type to make hollow chocolate eggs. Some plastic product lines in the USA were developed using this method some time between 1940 and 1950. The process has however taken long to take affect because it was considered as being a somewhat slow process

1. Mould fitting.
A predetermined amount of polymer in grain form is packed into a hollow mold. The mould is usually made of cast aluminium or sheet steel component. The coloring desired for the end item is pre compounded into the polymer. The most commonly used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this design of plastic manufacturing.

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 locked and put into the oven.

2. The heating and fusion phase.
Once inside the oven, the mold is spun on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mould. The turning is done slowly, about 20 spins per sixty seconds. The main thing that is important at this point is the amount of time the mold will spend inside the oven. If it stays to long, the component will lose value and strength, generating a faulty product. If it is removed from the oven prematurely, the polymer will not have liquefied properly, which develops bubbles in the finished product.

3. Mould cooling down.
When the component has completely spent the enough 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 somewhat for ease of extraction from the mold. This is one more step that relies a lot on the correct timing, since rapid cooling shrinks the material too rapidly, causing warping of the product.

4. The unloading or de-molding step.
When the product inside te mold has cooled successfully, the person handling the process can then take out the finished product from the mould. The technique is repeated from the start, giving a series of identical product lines.
