rotomolding-Valley Village-Rotational molding pertains to a plastic manufacturing technique that creates hollow stress-free products. The technique utilizes high temperatures and bi axial rotation to come up with seamless, one piece products that have different designs, colors and sizes. This technique is also referred to as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing processes in that no pressure is involved. It also has few contenders when it comes down to the manufacture of large size hollow products which are durable and inexpensive.There is a wide variety of product lines that are developed by this process including large size water tanks, automobile products, intricate designed medical items, leisure equipment, toys, canoes, commercial equipment among many others.This is because of the versatility in terms of style 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 Valley Village CA 91607, 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 rotocasting 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 Manufacturing-Valley Village-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 Valley Village 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 Rotomolding Procedure Components

This moulding method has been used since ancient times for creatingvseverl items. Egyptians for example, worked with rotomoulding procedures in the producing of ceramics. The Swiss were also utilizing this rotation method to create hollow chocolate eggs. Some plastic product lines in the USA were created utilizing this method some time between 1940 and 1950. The system has however taken long to catch on because it was considered to be a rather slow process

1. Mould readying.
A fixed measure of polymer in powder form is packed into a hollow mould. The mold is usually comprised of cast aluminium or sheet steel component. The coloration preferred for the end item 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 format of plastic manufacturing.

Pre-heating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is heated to temperatures between 500-700F. The mold with the powdered polymer is then secured and inserted inside the oven.

2. The heating and fusion step.
Once inside the oven, the mold is spun on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The turning is done gradually, about 20 revolutions per min. The main thing that is critical at this point is the amount of time the mold will spend inside the oven. If it overstays, the product will lose stability and durability, making a poor product. If it is removed from the oven too early, the polymer will not have flowed properly, which generates bubbles in the finished product.

3. Mould cooling.
When the product has completely spent the enough of time in the oven, it is then extracted for cooling. This may be done by air or water, or sometimes a mixture of both which generates a cool mist. When the product cools, it shrinks a little for ease of extraction from the mold. This is another step that depends a lot on the correct timing, since quick cooling reduces the material too quickly, causing bending of the product.

4. The removing or de-moulding step.
When the material within te mould has cooled correctly, the molder handling the process can then take out the completed item from the mould. The procedure is repeated from the start, providing a number of similar items.
