rotomolding-Soquel-Rotational moulding pertains to a plastic manufacturing practice that makes hollow stress-free product lines. The method depends on high temperatures and bi axial rotation to follow up with seamless, one piece items that have a wide range of shapes, sizes and colors. This technique is also known as rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The function that makes this different from other plastic manufacturing methods because no pressure is required. It also has few rivals when it comes to the manufacture of large hollow items which are durable and inexpensive.There is a wide range of products that are produced by this process including large water tanks, automobile materials, complex designed medical items, recreation equipment, toys, canoes, commercial equipment among many others.This is because of the versatility in regards to type and forms that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Soquel CA 95073, 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 rotomoulding 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 Manufacturing-Soquel-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 California 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 Soquel California 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 Process Components

This molding procedure has been used since earlier times for creatingvseverl products. Egyptians as an example, employed rotational molding procedures in the manufacturing of ceramics. The Swiss were also employing this rotation method to generate hollow chocolate eggs. Some plastic items in the USA were manufactured utilizing this approach some time between 1940 and 1950. Because it was thought of to be a very slow method, the method has however taken long to become popular

1. Mold fitting.
A fixed amount of polymer in powder form is filled into a hollow mould. The mould is usually composeded of cast aluminium or sheet steel material. The coloration needed for the final product is pre compounded into the polymer. The most typically used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this type of plastic manufacturing.

Pre-heating of the oven starts, and it can 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 positioned into the oven.

2. The heating and fusion procedure.
Once within the oven, the mould is spun on two axis so the powdered polymer melts from the heat and coats the inside if the mold. The turning is done slowly and gradually, about 20 rotations per min. One thing that is essential at this moment is the amount of time the mould will spend inside the oven. If it overstays, the product will lose value and strength, producing a poor product. If it is extracted from the oven prematurely, the polymer will not have liquefied correctly, which develops bubbles in the completed product.

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

4. The unloading or de-molding step.
Once the component within te mould has cooled correctly, the person handling the process can then take out the finalized product from the mold. The process is repeated from the start, making a number of identical products.
