rotomolding-Oakfield-Rotational molding pertains to a plastic production solution that generates hollow stress-free products. The method relies on high temperatures and bi axial rotation to come up with seamless, one piece objects that have many different designs, sizes and colors. This method is also called roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing methods in that no pressure is needed. It also has few rivals when it comes to the production of large size hollow products which are resilient and inexpensive.There is a wide variety of items that are generated by this process including large water tanks, automobile products, complex designed medical products, recreation equipment, toys, kayaks, industrial equipment among many others.This is because of the versatility in regards to design and forms that the process produces

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Oakfield NY 14125, 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-Oakfield-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 Oakfield 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 molding operation has been used since ancient times for creatingvseverl products. Egyptians for example, utilized rotational molding systems in the manufacturing of ceramics. The Swiss were also making use of this rotation type to create hollow chocolate eggs. Some plastic items in the USA were manufactured using this procedure some time between 1940 and 1950. The technique has however taken very long to catch on because it was thought of as being a somewhat slow-moving process

1. Mold preparation.
A fixed quantity of polymer in powder form is packed into a hollow mould. The mould is usually crafted from cast aluminium or sheet steel substance. The coloration needed for the finished item 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 assembly.

Pre-heating of the oven starts, and it may 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 sealed and placed inside the oven.

2. The heating and fusion phase.
Once within the oven, the mold is turned 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 revolutions per min. Something that is critical at this point is the period of time the mould will spend inside the oven. If it stays to long, the material will lose value and strength, producing a faulty item. If it is taken out from the oven prematurely, the polymer will not have flowed properly, which generates bubbles in the finalized product line.

3. Mold cooling down.
When the component has sufficiently 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 creates a cool mist. When the product cools, it shrinks somewhat for ease of extraction from the mould. This is one more measure that relies a lot on the ideal timing, since quick cooling reduces the material too quickly, causing bending of the product.

4. The un-loading or de-moulding step.
Once the material inside te mould has cooled properly, the person handling the operation can then extract the completed product from the mold. The technique is repeated from the start, providing a series of identical products.
