rotomolding-Farmington-Rotational moulding refers to a plastic production method that creates hollow stress-free product lines. The method relies upon high temperatures and bi axial rotation to follow up with seamless, one piece items that have a variety of shapes, sizes and colors. This method is also known as rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The attribute that makes this unique from other plastic manufacturing methods that no pressure is called for. It also has few rivals when it comes to the creation of large size hollow items which are resilient and inexpensive.There is a variety of product lines that are generated by this process including large water tanks, automobile products, intricate designed medical items, leisure equipment, toys, kayaks, industrialized equipment among many others.This is because of the versatility in regards to type 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 Farmington UT 84025, 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

Plastic Molding-Farmington-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 Utah 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 Farmington Utah 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 Method Components

This moulding method has been used since early times for creatingvseverl product lines. Egyptians as an example, used rotocasting systems in the making of ceramics. The Swiss were also using this rotation type to create hollow chocolate eggs. Some plastic items in the USA were made using this procedure some time between 1940 and 1950. Because it was looked at to be a relatively slow-moving system, the technique has however taken long to catch on

1. Mold preparation.
A fixed volume of polymer in particle form is loaded into a hollow mould. The mould is usually composeded of cast aluminium or sheet steel component. The color tone chosen for the final product 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 manufacturing.

Pre-heating of the oven starts, and it may be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then secured and installed inside the oven.

2. The heating and fusion process.
Once placed into the oven, the mold is spun on two axis so the powdered polymer liquefies from the heat and overlays the inside if the mould. The turning is done gradually, about 20 rotations per min. The main thing that is essential at this point is the period of time the mould will spend inside the oven. If it stays to long, the component will lose stability and strength, generating a poor item. If it is removed from the oven prematurely, the polymer will not have flowed properly, which generates bubbles in the finished item.

3. Mould cooling.
When the product has sufficiently spent the enough of time in the oven, it is then removed for cooling. This can be done by air or water, or sometimes a mixture of both which a cool mist. When the product cools, it shrinks somewhat for ease of removal from the mould. This is one more procedure that depends a lot on the right timing, since rapid cooling decreases the material too quick, causing warping of the material.

4. The offloading or de-molding step.
As soon as the material inside te mold has cooled adequately, the person taking care of the operation can then remove the completed item from the mould. The procedure is repeated from the start, providing a number of similar products.
