rotational moulding-Blue Point-Rotational moulding pertains to a plastic manufacturing method that makes hollow stress-free items. The procedure depends on high temperatures and bi axial rotation to follow up with seamless, one piece products that have different designs, colors and sizes. This technique is also called rotomoulding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing processes that no pressure is involved. It also has few contenders when it comes down to the creation of large size hollow products which are durable and inexpensive.There is a variety of items that are developed by this process including large water tanks, automobile items, sophisticated molded medical products, leisure equipment, toys, kayaks, commercial equipment among many others.This is because of the versatility in terms of type and forms that the process manufactures

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Blue Point NY 11715, 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 rotomoulding 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 Molded-Blue Point-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 Blue Point 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 Procedure Components

This moulding system has been used since early times for creatingvseverl product lines. Egyptians for example, applied rotational molding solutions in the manufacturing of ceramics. The Swiss were also employing this rotation method to generate hollow chocolate eggs. Some plastic product lines in the USA were created using this approach some time between 1940 and 1950. Considering that it was viewed to be a basically slow system, the procedure has however taken long to catch on

1. Mold preparation.
A predetermined quantity of polymer in powder form is filled into a hollow mould. The mould is usually constructed from cast aluminium or sheet steel substance. The colour desired for the final item 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 design of plastic engineering.

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 mould with the powdered polymer is then secured and put into the oven.

2. The heating up and fusion phase.
Once inside the oven, the mold is revolved on two axis so the powdered polymer liquefies from the heat and coats the inside if the mold. The spinning is done slowly and gradually, about 20 spins per sixty seconds. One thing that is important at this point is the period of time the mould will spend inside the oven. If it stays to long, the component will lose value and durability, making a poor item. If it is extracted from the oven too early, the polymer will not have flowed correctly, which generates bubbles in the completed product.

3. Mold cooling.
When the product has sufficiently 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 reduces a little for ease of removal from the mould. This is yet another procedure that depends a lot on the ideal timing, since rapid cooling reduces the material too rapidly, causing bending of the product.

4. The discharging or de-molding step.
When the material inside te mould has cooled properly, the molder taking care of the process can then take out the completed item from the mould. The function is repeated from the start, making a series of exact products.
