INJECTION MOULDING MANUFACTURER MALAYSIA – A WIDELY USED TECHNIQUE

Though most of us have not heard of the term Injection Moulding, we encounter its products almost everywhere in our daily lives. Automotive parts, packaging, bottle caps, parts of musical instruments, one piece chairs, furniture parts and most plastic products we encounter in our daily lives, are the wide range of applications which use the injection moulding process. An item made using the injection moulding system may look good on the outside, but there are crucial inputs of the process, which determine quality, safety and service life of the item.

Injection Moulding is basically melted plastic being formed into a desired shape using a mould, which is split into two halves. The plastic material used, as well as the machinery and the process, are all important for the outcome of the final product.

MATERIAL:

Mainly two types of plastics are used. The plastic will be either thermosetting or thermoplastic. For injection moulding applications, all thermoplastics and some thermosetting plastics can be used. The commonly used plastic materials are epoxy, phenolic, nylon, polyethylene, polystyrene etc.

The plastic cannot be used directly. It has to be compounded with various other materials such as stabilizers, lubricants, colorants etc. These additives are crucial to the correct formation of the part, service life as well as safety. This is why it is important that only safe and approved chemicals are used as a part of the injection moulding process.

METHOD:

As per the formula, the plastic and additives are all mixed in a mixer, at the correct speed and temperature. This is a very important process, as too little or too much mixing and wrong temperature, will cause defects in the products being manufactured. Once the mixing is completed, the batch is transferred to the injection moulding machine. The machine consists of a material hopper, an injection ram and a heating unit. The machine holds a mould, which is usually split into two halves. The plastic material is forced into the mould by the injection ram and air is blown into the mould. This forces the plastic to form into the shape of the mould. After the setting time is over, the moulds are separated and the part ejected. Further processing to remove extra plastic may be required.

The mould, in which the plastic part gets its shape, is of crucial importance. It is split into two halves. Each part contains one half of the profile. It has to be designed in such a way that important technical parameters such as material flow, temperature etc. are maintained correctly. A mould is usually made of steel or aluminium. The cost of the mould is high, but since a large volume of parts can be made using the same mould, the cost of the mould per piece comes down over time.

Though the part produced may look good on the outside, it may have hidden flaws which affect its life, safety etc. It is important that when you are purchasing a product made by Injection Moulding, it is better to source them from a reputed manufacturer.
