rotational molding-Death Valley-Rotational molding pertains to a plastic production technique that makes hollow stress-free items. The technique relies on high temperatures and bi axial rotation to come up with seamless, one piece products that have various shapes, colors and sizes. This technique is also referred to as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl styles.

The component that makes this different from other plastic manufacturing methods in that no pressure is involved. It also has few contenders when it pertains to the manufacture of large size hollow products which are resilient and inexpensive.There is a wide variety of items that are generated by this process including big water tanks, automobile products, intricate shaped medical items, recreation equipment, toys, canoes, industrialized equipment among many others.This is due to the flexibility in regards to design and shapes that the process manufactures

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Death Valley CA 92328, 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 rotomolding 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-Death Valley-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 Death Valley 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 Procedure in Detail

This moulding method has been used since ancient times for creatingvseverl product lines. Egyptians for example, employed rotomoulding methods in the creating of ceramics. The Swiss were also working with this rotation type to create hollow chocolate eggs. Some plastic products in the USA were developed using this technique some time between 1940 and 1950. The process has however taken long to take affect because it was considered to be a moderately slow-moving process

1. Mould fitting.
A predetermined amount of polymer in powder form is packed into a hollow mould. The mold is usually made of cast aluminium or sheet steel substance. The color tone intended for the final item 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 assembly.

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 locked and positioned into the oven.

2. The heat and fusion phase.
Once within the oven, the mold is turned on two axis so the powdered polymer liquefies from the heat and coats the inside if the mold. The spinning is done gradually, about 20 revolutions per minute. One thing that is essential at this point is the amount of time the mould will spend inside the oven. If it stays to long, the product will lose stability and strength, creating a weak item. If it is taken out from the oven prematurely, the polymer will not have flowed properly, which generates bubbles in the completed product.

3. Mold cooling.
When the product has sufficiently spent the right 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 somewhat for ease of extraction from the mold. This is one more measure that depends a lot on the correct timing, since quick cooling reduces the material too quick, causing bending of the product.

4. The removing or de-moulding phase.
As soon as the component within te mould has cooled properly, the molder taking care of the procedure can then extract the completed item from the mold. The process is repeated from the beginning, providing a series of exact products.
