rotomoulding-Clarksburg-Rotational moulding refers to a plastic production practice that creates hollow stress-free product lines. The process utilizes high temperatures and bi axial rotation to come up with seamless, one piece items that have several designs, sizes and colors. This technique is also referred to as rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl styles.

The function that makes this different from other plastic manufacturing methods because no pressure is involved. It also has few contenders when it comes down to the manufacture of large size hollow items which are long-lasting and inexpensive.There is a wide variety of products that are generated by this process including large size water tanks, automobile materials, intricate shaped medical products, recreation equipment, toys, canoes, industrial equipment among many others.This is due to the versatility in regards to type and forms that the process produces

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Clarksburg WV 26301, 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 roto-molding 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-Clarksburg-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 West Virginia 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 Clarksburg West Virginia 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 Method in Detail

This molding technique has been used since ancient times for creatingvseverl products. Egyptians for instance, worked with rotomoulding procedures in the creating of ceramics. The Swiss were also using this rotation style to make hollow chocolate eggs. Some plastic products in the USA were developed using this technique some time between 1940 and 1950. Due to the fact that it was thought of to be a basically slow method, the system has however taken long to catch on

1. Mould prep work.
A fixed measure of polymer in powder form is loaded into a hollow mould. The mould is usually built from cast aluminium or sheet steel component. The color tone desired for the finished 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 type of plastic production.

Preheating of the oven starts, and it can be done by either conduction, convection or sometimes radiation. It is warmed to temperatures between 500-700F. The mould with the powdered polymer is then sealed and placed into the oven.

2. The heat and fusion process.
Once placed into the oven, the mould is rotated on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The turning is done slowly and gradually, about 20 spins per sixty seconds. One thing that is crucial at this moment is the period of time the mould will spend within the oven. If it overstays, the component will lose value and strength, creating a weak item. If it is extracted from the oven too early, the polymer will not have flowed correctly, which develops bubbles in the finished product.

3. Mould cooling down.
When the material has completely 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 material cools, it reduces somewhat for ease of removal from the mould. This is an additional procedure that depends upon a lot on the correct timing, since rapid cooling decreases the material too rapidly, causing bending of the item.

4. The unloading or de-molding phase.
As soon as the material within te mould has cooled successfully, the person taking care of the operation can then remove the finalized item from the mold. The process is repeated from the start, providing a series of similar items.
