rotational moulding-Mount Kisco-Rotational moulding pertains to a plastic production technique that makes hollow stress-free items. The technique relies upon high temperatures and bi axial rotation to come up with seamless, one piece items that have different forms, sizes and colors. This technique is also called rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The attribute that makes this unique from other plastic manufacturing processes that no pressure is needed. It also has few competitors when it comes down to the manufacture of large hollow products which are resilient and inexpensive.There is a variety of product lines that are produced by this process including big water tanks, automobile products, intricate molded medical items, recreation equipment, toys, kayaks, commercial equipment among many others.This is due to the versatility 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 Mount Kisco NY 10549, 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-Mount Kisco-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 Mount Kisco 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 Rotomolding Method Components

This molding operation has been used since ancient times for creatingvseverl items. Egyptians as an example, employed roto-molding procedures in the manufacturing of ceramics. The Swiss were also working with this rotation style to generate hollow chocolate eggs. Some plastic items in the USA were created utilizing this procedure some time between 1940 and 1950. The procedure has however taken long to catch on because it was looked at as being a rather slow-moving process

1. Mold prep work.
A predetermined measure of polymer in powder form is filled into a hollow mould. The mold is usually made from cast aluminium or sheet steel component. The coloration intended for the end 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 design of plastic manufacturing.

Pre-heating of the oven starts, and it can 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 installed inside the oven.

2. The heat and fusion procedure.
Once placed into the oven, the mould is rotated on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mold. The turning is done slowly and gradually, about 20 revolutions per minute. The main 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 stability and durability, producing a poor product. If it is removed from the oven too early, the polymer will not have liquefied properly, which generates bubbles in the finished item.

3. Mould cooling down.
When the material has sufficiently spent the correct amount of time in the oven, it is then taken out for cooling. This may be done by air or water, or sometimes a mixture of both which creates a cool mist. When the material cools, it shrinks slightly for ease of extraction from the mould. This is an additional procedure that depends a lot on the correct timing, since rapid cooling reduces the material too quick, causing warping of the product.

4. The unloading or de-moulding step.
Once the product inside te mold has cooled effectively, the molder handling the operation can then remove the finalized item from the mould. The technique is repeated from the beginning, giving a series of exact product lines.
