Rotational moulding pertains to a plastic production procedure that produces hollow stress-free items. The technique relies on high temperatures and bi axial rotation to come up with seamless, one piece objects that have a wide range of designs, sizes and colors. This method is also referred to as rotomoulding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.
The benefit that makes this different from other plastic manufacturing techniques because no pressure is needed. It also has few contenders when it involves the production of large size hollow products which are resilient and inexpensive.There is a wide variety of items that are created by this process including large water tanks, automobile products, intricate shaped medical products, recreation equipment, toys, kayaks, commercial equipment among many others.This is due to the versatility in terms of type 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 Summerfield LA 71079, 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
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 Louisiana 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 Summerfield Louisiana 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 Components
This moulding technique has been used since ancient times for creatingvseverl items. Egyptians for example, used rotocasting methods in the making of ceramics. The Swiss were also employing this rotation technique to make hollow chocolate eggs. Some plastic product lines in the USA were manufactured using this procedure some time between 1940 and 1950. Due to the fact that it was viewed to be a fairly slow procedure, the technique has however taken long to catch on
1. Mould fitting.
A predetermined amount of polymer in powder form is loaded into a hollow mold. The mold is usually comprised of cast aluminium or sheet steel component. The color desired for the end product is pre compounded into the polymer. The most commonly used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this format 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 sealed and positioned inside the oven.
2. The heating up and fusion procedure.
Once placed into the oven, the mould is turned on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The rotation is done slowly, about 20 spins per min. The main thing that is essential at this moment is the amount of time the mould will spend within the oven. If it overstays, the product will lose stability and strength, making a weak item. If it is removed from the oven too early, the polymer will not have melted correctly, which generates bubbles in the finalized item.
3. Mould cooling down.
When the product has completely spent the correct amount of time in the oven, it is then removed for cooling. This may be done by air or water, or sometimes a mixture of both which a cool mist. When the material cools, it reduces slightly for ease of removal from the mold. This is another procedure that relies a lot on the ideal timing, since quick cooling reduces the material too quick, causing warping of the item.
4. The unloading or de-molding phase.
Once the material inside te mold has cooled adequately, the person handling the process can then extract the completed product from the mold. The procedure is repeated from the start, supplying a series of similar product lines.
