rotomolding-Kidron-Rotational molding refers to a plastic production procedure that produces hollow stress-free product lines. The technique depends on high temperatures and bi axial rotation to come up with seamless, one piece objects that have varying designs, colors and sizes. This method is also called roto-molding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The attribute that makes this unique from other plastic manufacturing methods in that no pressure is needed. It also has few rivals when it involves the manufacture of sizable hollow products which are resilient and inexpensive.There is a wide range of items that are produced by this process including large water tanks, automobile materials, intricate shaped medical products, leisure equipment, toys, canoes, industrial equipment among many others.This is due to the versatility in regards to design and shapes that the process manufactures

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Kidron OH 44636, 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-Kidron-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 Ohio 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 Kidron Ohio 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 in Detail

This molding system has been used since ancient times for creatingvseverl products. Egyptians for example, employed rotational molding solutions in the making of ceramics. The Swiss were also making use of this rotation method to create hollow chocolate eggs. Some plastic products in the USA were manufactured using this technique some time between 1940 and 1950. The technique has however taken very long to catch on because it was thought of as being a rather slow-moving process

1. Mould fitting.
A predetermined amount of polymer in powder form is filled into a hollow mould. The mould is usually crafted from cast aluminium or sheet steel material. The colour intended for the final item 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 production.

Pre-heating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then secured and positioned inside the oven.

2. The heating up and fusion step.
Once placed into the oven, the mould is turned on two axis so the powdered polymer melts from the heat and layers the inside if the mold. The turning is done slowly, about 20 spins per sixty seconds. Something that is vital at this point is the period of time the mold will spend inside the oven. If it stays to long, the material will lose value and strength, making a faulty item. If it is removed from the oven prematurely, the polymer will not have liquefied properly, which develops bubbles in the finalized product line.

3. Mould cooling down.
When the material has completely spent the correct amount of time in the oven, it is then extracted 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 shrinks a little for ease of extraction from the mould. This is another procedure that depends upon a lot on the right timing, since quick cooling decreases the material too rapidly, causing warping of the product.

4. The removing or de-moulding step.
Once the material inside te mould has cooled effectively, the molder taking care of the operation can then take out the finalized product from the mould. The procedure is repeated from the beginning, giving a number of similar product lines.
