roto-molding-West Point-Rotational molding refers to a plastic manufacturing procedure that generates hollow stress-free items. The technique depends on high temperatures and bi axial rotation to follow up with seamless, one piece items that have a wide range of designs, sizes and colors. This technique is also known as rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The function that makes this unique from other plastic manufacturing techniques that no pressure is involved. It also has few rivals when it pertains to the manufacture of large hollow items which are long-lasting and inexpensive.There is a wide range of product lines that are produced by this process including large water tanks, automobile products, complex molded medical products, recreation equipment, toys, kayaks, commercial equipment among many others.This is due to the flexibility in regards to 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 West Point MS 39773, 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 rotational moulding 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-West Point-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 Mississippi 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 West Point Mississippi 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 Process in Detail

This molding technique has been used since early times for creatingvseverl product lines. Egyptians for instance, worked with roto-molding methods in the of ceramics. The Swiss were also working with this rotation type to create hollow chocolate eggs. Some plastic products in the USA were created utilizing this technique some time between 1940 and 1950. The procedure has however taken very long to catch on because it was looked at to be a moderately slow-moving process

1. Mold readying.
A fixed measure of polymer in grain form is packed into a hollow mold. The mold is usually built from cast aluminium or sheet steel component. The coloration preferred for the finished 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 style of plastic manufacturing.

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

2. The heating up and fusion step.
Once within the oven, the mold is turned on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The rotation is done slowly and gradually, about 20 spins per minute. The main thing that is crucial at this moment is the amount of time the mould will spend within the oven. If it overstays, the product will lose value and durability, making a poor product. If it is taken out from the oven prematurely, the polymer will not have liquefied correctly, which develops bubbles in the finished item.

3. Mold cooling down.
When the component has completely spent the enough 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 creates a cool mist. When the product cools, it reduces slightly for ease of extraction from the mold. This is yet another measure that depends a lot on the right timing, since quick cooling reduces the material too quickly, causing warping of the item.

4. The discharging or de-molding step.
As soon as the component inside te mold has cooled properly, the molder taking care of the procedure can then remove the finished item from the mold. The technique is repeated from the beginning, making a series of identical product lines.
