rotocasting-Titonka-Rotational molding pertains to a plastic manufacturing method that produces hollow stress-free products. The process 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 technique is also referred to as rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The attribute that makes this different from other plastic manufacturing procedures in that no pressure is required. It also has few competitors when it comes to the creation of large size hollow products which are long lasting and inexpensive.There is a wide variety of items that are developed by this process including large water tanks, automobile products, intricate shaped medical items, recreation equipment, toys, canoes, industrial equipment among many others.This is due to the flexibility in regards to type and shapes that the process produces

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Titonka IA 50480, 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 roto-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-Titonka-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 Iowa 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 Titonka Iowa 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 Roto-Molding Process in Detail

This moulding system has been used since earlier times for creatingvseverl products. Egyptians for example, used rotational molding solutions in the producing of ceramics. The Swiss were also working with this rotation approach to make hollow chocolate eggs. Some plastic products in the USA were made using this technique some time between 1940 and 1950. The process has however taken long to catch on because it was looked at as being a relatively slow-moving process

1. Mould preparation.
A fixed amount of polymer in particle form is filled into a hollow mold. The mold is usually built from cast aluminium or sheet steel substance. The color tone preferred for the finished 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 design of plastic manufacturing.

Preheating 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 mould with the powdered polymer is then secured and inserted inside the oven.

2. The heating and fusion phase.
Once inside the oven, the mold is spun on two axis so the powdered polymer liquefies from the heat and layers the inside if the mold. The turning is done gradually, about 20 revolutions per min. The main thing that is important at this point is the period of time the mold will spend inside the oven. If it overstays, the product will lose value and strength, creating a faulty product. If it is removed from the oven prematurely, the polymer will not have flowed properly, which creates bubbles in the finalized product line.

3. Mold cooling.
When the component has sufficiently spent the correct amount of time in the oven, it is then taken out for cooling. This can be done by air or water, or sometimes a mixture of both which generates a cool mist. When the component cools, it shrinks a little for ease of removal from the mold. This is an additional step that relies a lot on the right timing, since rapid cooling shrinks the material too fast, causing warping of the material.

4. The offloading or de-molding phase.
As soon as the material inside te mould has cooled adequately, the molder taking care of the procedure can then extract the finalized product from the mold. The procedure is repeated from the beginning, giving a number of exact product lines.
