rotomolding-Sodus-Rotational molding refers to a plastic manufacturing technique that generates hollow stress-free product lines. The method relies on high temperatures and bi axial rotation to follow up with seamless, one piece objects that have varying forms, colors and sizes. This procedure is also referred to as rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The attribute that makes this different from other plastic manufacturing processes in that no pressure is called for. It also has few rivals when it pertains to the manufacture of sizable hollow items which are long-lasting and inexpensive.There is a wide range of product lines that are generated by this process including big water tanks, automobile items, intricate designed medical items, recreation equipment, toys, canoes, commercial equipment among many others.This is due to the flexibility in terms of design and forms that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Sodus NY 14551, 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 moulding 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-Sodus-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 New York 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 Sodus New York 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 Method Components

This moulding method has been used since ancient times for creatingvseverl products. Egyptians as an example, applied rotational molding procedures in the producing of ceramics. The Swiss were also applying this rotation approach to generate hollow chocolate eggs. Some plastic items in the USA were made using this approach some time between 1940 and 1950. Since it was considered to be a rather slow-moving method, the method has however taken long to become popular

1. Mold preparation.
A predetermined amount of polymer in powder form is loaded into a hollow mould. The mould is usually comprised of cast aluminium or sheet steel component. The colour wanted for the finished 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 engineering.

Pre-heating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is heated 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 placed into the oven, the mold is turned on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The turning is done gradually, about 20 rotations per minute. One thing that is crucial at this moment is the amount of time the mould will spend inside the oven. If it overstays, the material will lose stability and strength, producing a poor item. If it is taken out from the oven too early, the polymer will not have liquefied correctly, which creates bubbles in the completed product.

3. Mould cooling down.
When the material has completely spent the correct 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 generates a cool mist. When the component cools, it shrinks a little for ease of extraction from the mold. This is yet another step that depends a lot on the correct timing, since quick cooling shrinks the material too quick, causing bending of the material.

4. The un-loading or de-moulding phase.
When the product within te mold has cooled properly, the person managing the operation can then take out the finished item from the mold. The function is repeated from the beginning, providing a number of similar product lines.
