rotocasting-Sandia Park-Rotational molding pertains to a plastic manufacturing solution that produces hollow stress-free product lines. The technique relies on high temperatures and bi axial rotation to come up with seamless, one piece products that have many different designs, sizes and colors. This procedure is also referred to as rotomoulding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl types.

The function that makes this different from other plastic manufacturing procedures because no pressure is required. It also has few rivals when it comes down to the production of large size hollow items which are resilient and inexpensive.There is a wide variety of product lines that are generated by this process including large water tanks, automobile materials, complex shaped medical items, recreation equipment, toys, canoes, industrialized equipment among many others.This is due to the flexibility in terms of 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 Sandia Park NM 87047, 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 Products-Sandia Park-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 New Mexico 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 Sandia Park New Mexico 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 Rotomolding Process in Detail

This molding method has been used since ancient times for creatingvseverl items. Egyptians for example, worked with roto-molding methods in the of ceramics. The Swiss were also making use of this rotation technique to make hollow chocolate eggs. Some plastic product lines in the USA were made using this approach some time between 1940 and 1950. Given that it was thought of to be a somewhat slow method, the procedure has however taken long to become popular

1. Mould preparation.
A predetermined measure of polymer in grain form is filled into a hollow mold. The mould is usually composeded of cast aluminium or sheet steel material. The coloration needed for the finished 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.

Preheating of the oven follows, 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 secured and put inside the oven.

2. The heating up and fusion step.
Once placed into the oven, the mould is spun on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The spinning is done gradually, about 20 rotations per min. Something that is crucial at this point is the amount of time the mold will spend inside the oven. If it stays to long, the component will lose value and durability, generating a weak item. If it is removed from the oven too early, the polymer will not have melted properly, which produces bubbles in the completed item.

3. Mold cooling down.
When the product has completely spent the correct amount of time in the oven, it is then extracted 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 reduces somewhat for ease of extraction from the mould. This is another step that depends a lot on the correct timing, since rapid cooling shrinks the material too fast, causing bending of the product.

4. The removing or de-molding phase.
Once the material inside te mold has cooled successfully, the person handling the procedure can then extract the finalized item from the mould. The technique is repeated from the start, making a number of exact product lines.
