rotomoulding-Binger-Rotational moulding refers to a plastic production method that produces hollow stress-free product lines. The method relies upon high temperatures and bi axial rotation to come up with seamless, one piece products that have a variety of designs, colors and sizes. This procedure is also called rotomolding or rotocasting. Sometimes the term slush moulding is used for certain liquid vinyl forms.

The feature that makes this different from other plastic manufacturing techniques because no pressure is needed. It also has few competitors when it comes to the production of large size hollow products which are long lasting and inexpensive.There is a wide range of product lines that are produced 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 versatility in regards to type and shapes that the process creates

Benefits of Using Rotomolding to Manufacture Plastic Products

  • Relatively low tooling costs.
    When compared to other plastic manufacturing processes in Binger OK 73009, 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

Plastic Products-Binger-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 Oklahoma 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 Binger Oklahoma 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 Procedure in Detail

This moulding process has been used since earlier times for creatingvseverl product lines. Egyptians as an example, worked with rotomoulding techniques in the making of ceramics. The Swiss were also applying this rotation design to create hollow chocolate eggs. Some plastic product lines in the USA were developed using this technique some time between 1940 and 1950. Considering that it was viewed to be a rather slow technique, the system has however taken long to become popular

1. Mould prep work.
A predetermined volume of polymer in grain form is loaded into a hollow mold. The mold is usually composeded of cast aluminium or sheet steel substance. The color tone intended for the end item 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 format of plastic manufacturing.

Pre-heating 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 locked and put into the oven.

2. The heat and fusion process.
Once placed into the oven, the mold is spun on two axis so the powdered polymer melts from the heat and overlays the inside if the mold. The turning is done slowly and gradually, about 20 rotations per minute. One thing 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, producing a poor item. If it is taken out from the oven prematurely, the polymer will not have flowed correctly, which produces bubbles in the completed product.

3. Mould cooling down.
When the product 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 a cool mist. When the material cools, it shrinks somewhat for ease of extraction from the mold. This is yet another step that depends upon a lot on the correct timing, since quick cooling reduces the material too quickly, causing bending of the material.

4. The removing or de-molding step.
When the component within te mould has cooled correctly, the molder taking care of the operation can then remove the finished product from the mould. The technique is repeated from the start, making a number of exact product lines.
