rotocasting-Somers-Rotational molding refers to a plastic manufacturing technique that makes hollow stress-free product lines. The technique uses high temperatures and bi axial rotation to come up with seamless, one piece products that have many different shapes, colors and sizes. This method is also referred to as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl styles.

The component that makes this unique from other plastic manufacturing processes that no pressure is called for. It also has few rivals when it pertains to the creation of sizable hollow products which are resilient and inexpensive.There is a variety of product lines that are created by this process including large size water tanks, automobile items, sophisticated shaped medical products, recreation equipment, toys, canoes, industrial equipment among many others.This is due to the versatility in regards to design and shapes that the process makes

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Somers CT 6071, 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 Molding-Somers-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 Connecticut 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 Somers Connecticut 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 molding operation has been used since early times for creatingvseverl products. Egyptians for example, applied rotational molding procedures in the making of ceramics. The Swiss were also applying this rotation design to make hollow chocolate eggs. Some plastic items in the USA were developed using this technique some time between 1940 and 1950. Considering that it was regarded to be a fairly slow-moving process, the approach has however taken long to catch on

1. Mold fitting.
A fixed volume of polymer in particle form is filled into a hollow mold. The mould is usually made from cast aluminium or sheet steel substance. The coloring desired for the end goods is pre compounded into the polymer. The most typically used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this style 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 mold with the powdered polymer is then secured and inserted into the oven.

2. The heating up and fusion procedure.
Once placed into 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 minute. One thing that is critical at this point is the period of time the mold will spend within the oven. If it overstays, the material will lose stability and strength, making a faulty item. If it is extracted from the oven prematurely, the polymer will not have melted properly, which produces bubbles in the finished product line.

3. Mould cooling down.
When the component has sufficiently spent the right amount of time in the oven, it is then removed for cooling. This may be done by air or water, or sometimes a mixture of both which generates a cool mist. When the component 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 rapidly, causing bending of the item.

4. The removing or de-moulding phase.
As soon as the component within te mould has cooled successfully, the person handling the procedure can then extract the completed product from the mould. The procedure is repeated from the beginning, supplying a number of identical products.
