roto-molding-Mashpee-Rotational molding pertains to a plastic manufacturing technique that creates hollow stress-free product lines. The process uses high temperatures and bi axial rotation to come up with seamless, one piece products that have varying designs, colors and sizes. This technique is also known as roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The component that makes this different from other plastic manufacturing processes because no pressure is called for. It also has few competitors when it comes to the production of large size hollow items which are resilient and inexpensive.There is a wide range of products that are produced by this process including large water tanks, automobile materials, complex designed medical products, recreation equipment, toys, kayaks, commercial equipment among many others.This is due to the flexibility in regards to type and shapes that the process produces

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Mashpee MA 2649, 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-Mashpee-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 Massachusetts 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 Mashpee Massachusetts 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 Procedure in Detail

This molding operation has been used since earlier times for creatingvseverl products. Egyptians for instance, employed rotomoulding techniques in the producing of ceramics. The Swiss were also employing this rotation technique to generate hollow chocolate eggs. Some plastic products in the USA were developed utilizing this technique some time between 1940 and 1950. Due to the fact that it was looked at to be a relatively slow-moving approach, the technique has however taken long to become popular

1. Mold prep work.
A fixed quantity of polymer in grain form is loaded into a hollow mold. The mold is usually crafted from cast aluminium or sheet steel material. The colour needed for the end product 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 style of plastic production.

Preheating 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 mold with the powdered polymer is then sealed and placed within the oven.

2. The heating up and fusion process.
Once inside the oven, the mold is revolved on two axis so the powdered polymer liquefies from the heat and coats the inside if the mould. The turning is done slowly, about 20 revolutions per min. Something that is vital at this moment is the amount of time the mould will spend inside the oven. If it stays to long, the material will lose value and durability, generating a weak item. If it is taken out from the oven too early, the polymer will not have melted correctly, which develops bubbles in the completed product.

3. Mold cooling.
When the product 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 creates a cool mist. When the material cools, it reduces slightly for ease of removal from the mold. This is an additional measure that relies a lot on the ideal timing, since quick cooling shrinks the material too quick, causing warping of the item.

4. The offloading or de-moulding phase.
Once the product within te mold has cooled properly, the person managing the procedure can then take out the finalized product from the mould. The technique is repeated from the beginning, making a series of similar items.
