rotomoulding-Burbank-Rotational molding pertains to a plastic production procedure that creates hollow stress-free product lines. The process relies on high temperatures and bi axial rotation to follow up with seamless, one piece items that have a variety of designs, sizes and colors. This method is also known as roto-molding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl styles.

The feature that makes this unique from other plastic manufacturing processes because no pressure is called for. It also has few contenders when it comes to the production of sizable hollow products which are long lasting and inexpensive.There is a variety of products that are created by this process including large size water tanks, automobile products, complex shaped medical items, leisure equipment, toys, canoes, industrialized equipment among many others.This is due to the flexibility in regards to design 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 Burbank CA 91501, 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

Custom Molded-Burbank-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 California 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 Burbank California 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 Method Components

This molding operation has been used since earlier times for creatingvseverl product lines. Egyptians as an example, worked with rotocasting methods in the of ceramics. The Swiss were also employing this rotation style to make hollow chocolate eggs. Some plastic products in the USA were manufactured utilizing this approach some time between 1940 and 1950. Considering that it was viewed to be a rather slow process, the method has however taken long to catch on

1. Mold preparation.
A fixed measure of polymer in particle form is loaded into a hollow mold. The mold is usually comprised of cast aluminium or sheet steel substance. The coloration preferred for the finished goods 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 type of plastic production.

Preheating of the oven starts, and it may 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 sealed and inserted within the oven.

2. The heating up and fusion procedure.
Once placed into the oven, the mould is revolved on two axis so the powdered polymer melts from the heat and layers the inside if the mould. The rotation is done slowly and gradually, about 20 revolutions per min. The main thing that is important at this moment is the period of time the mould will spend inside the oven. If it stays to long, the material will lose value and durability, creating a poor product. If it is taken out from the oven prematurely, the polymer will not have flowed properly, which develops bubbles in the finished product.

3. Mold cooling.
When the component has completely 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 reduces a little for ease of removal from the mold. This is yet another step that depends a lot on the correct timing, since rapid cooling decreases the material too quick, causing warping of the product.

4. The offloading or de-molding phase.
As soon as the component inside te mold has cooled adequately, the molder handling the process can then extract the completed product from the mould. The function is repeated from the start, giving a series of exact items.
