Injection Moulding Process Simplified

Injection moulding is one of the most used industrial ways of designing synthetic parts. The process involves the application of a moulding machine, which have a huge difference in size, intricacy and use. The synthetic part is thawed in the moulding contraption and then introduced into the mould, where it solidifies and cools. The injection moulding process is further discussed below.

Injection moulding can be applied in the production of numerous day to day products. The actual process is very easy and includes four main phases; the first one is the clamping phase where before the material is injected into the mould, the two parts of the mould must be shut tightly by the compressing component. One side is then attached into the injection mould and the other left free to slide. A clamping unit is then used to push the moulds together using high pressure so as to bind them while the substance is introduced into the clamp. The time used is dependent on the power of the machine where high power machines use little time and low power machines use much more time. The next step in the injection moulding process is the injection itself where the material is led into the machine. The substance is melted using stress and high temperatures. The molten material is then introduced swiftly and the increase in pressure binds the materials.

The next phase in injection moulding is the cooling phase, where it solidifies as it is introduced to the moulding surfaces. As it cools it takes up the form of the preferred part, one disadvantage is that it might shrink during this process. In order to correct this defect more material should be reintroduced into the mould. The mould should then be left to cool.

The final phase in the injection moulding process is the ejection phase where the part is removed from the mould. This is an easy task because the machines have an ejection structure placed in the back side of the mould. The process requires the exertion of force because of the shrinking of the material which makes it stick to the mould. After careful ejection the machine should be clumped shut to prepare for the next process.

The injection moulding process requires the incorporation of post processing services. This ensures quality assurance. The material that remains in the mould must be removed and recycled again. This method is efficient as it allows recycling of materials thus saving on production costs. Injection moulding is the cheapest method of producing high quality merchandise and manufacturers should be willing to take advantage of this fact.
