rotational molding-Ogdensburg-Rotational molding pertains to a plastic manufacturing technique that produces hollow stress-free product lines. The technique uses high temperatures and bi axial rotation to follow up with seamless, one piece items that have a variety of shapes, sizes and colors. This technique is also referred to as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The component that makes this unique from other plastic manufacturing methods because no pressure is required. It also has few contenders when it comes to the creation of large hollow items which are durable and inexpensive.There is a wide range of products that are produced by this process including large water tanks, automobile materials, sophisticated designed medical items, leisure equipment, toys, canoes, industrialized equipment among many others.This is because of the versatility in regards to type and forms that the process develops

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Ogdensburg NJ 7439, 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 molding 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-Ogdensburg-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 Jersey 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 Ogdensburg New Jersey 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 Rotomoulding Process Components

This moulding operation has been used since earlier times for creatingvseverl product lines. Egyptians as an example, used rotocasting methods in the producing of ceramics. The Swiss were also applying this rotation approach to create hollow chocolate eggs. Some plastic products in the USA were manufactured using this technique some time between 1940 and 1950. Given that it was looked at to be a rather slow process, the approach has however taken long to catch on

1. Mould prep work.
A fixed quantity of polymer in particle form is filled into a hollow mold. The mold is usually built from cast aluminium or sheet steel substance. The colour wanted for the final 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 design of plastic assembly.

Pre-heating of the oven starts, 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 locked and put within the oven.

2. The heat and fusion step.
Once inside the oven, the mold is revolved on two axis so the powdered polymer melts from the heat and overlays the inside if the mould. The spinning is done gradually, about 20 revolutions per minute. Something that is important at this point is the period of time the mold will spend within the oven. If it stays to long, the product will lose value and durability, making a poor item. If it is extracted from the oven prematurely, the polymer will not have melted correctly, which develops bubbles in the completed item.

3. Mold cooling.
When the product has completely spent the right 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 slightly for ease of removal from the mold. This is another measure that depends a lot on the right timing, since quick cooling shrinks the material too fast, causing warping of the product.

4. The offloading or de-molding step.
Once the component within te mould has cooled adequately, the molder handling the process can then take out the completed item from the mould. The function is repeated from the start, making a series of similar items.
