rotomoulding-Ft Mitchell-Rotational molding pertains to a plastic production practice that makes hollow stress-free items. The technique depends on high temperatures and bi axial rotation to follow up with seamless, one piece items that have several forms, colors and sizes. This procedure is also known as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl styles.

The feature that makes this different from other plastic manufacturing methods because no pressure is called for. It also has few contenders when it comes to the manufacture of large hollow products which are resilient and inexpensive.There is a wide variety of product lines that are developed by this process including big water tanks, automobile items, complex shaped medical products, leisure equipment, toys, kayaks, commercial equipment among many others.This is due to the versatility in terms of 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 Ft Mitchell KY 41017, 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 Molding-Ft Mitchell-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 Kentucky 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 Ft Mitchell Kentucky 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 Method in Detail

This moulding technique has been used since earlier times for creatingvseverl product lines. Egyptians as an example, employed roto-molding techniques in the manufacturing of ceramics. The Swiss were also working with this rotation type to generate hollow chocolate eggs. Some plastic product lines in the USA were developed using this approach some time between 1940 and 1950. The process has however taken very long to take affect because it was considered to be a relatively slow-moving process

1. Mold preparation.
A predetermined volume of polymer in powder form is packed into a hollow mold. The mold is usually composeded of cast aluminium or sheet steel substance. The coloration wanted for the finished 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 format of plastic manufacturing.

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 secured and put within 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 coats the inside if the mold. The turning is done gradually, about 20 spins per min. One thing that is important at this moment is the amount of time the mold will spend within the oven. If it stays to long, the material will lose value and durability, creating a weak item. If it is taken out from the oven prematurely, the polymer will not have melted correctly, which develops bubbles in the finished 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 creates a cool mist. When the product cools, it shrinks somewhat for ease of extraction from the mould. This is yet another measure that depends a lot on the ideal timing, since rapid cooling decreases the material too rapidly, causing bending of the material.

4. The discharging or de-moulding step.
When the product within te mold has cooled correctly, the molder taking care of the procedure can then remove the finished item from the mould. The procedure is repeated from the beginning, giving a number of identical items.
