Injection Molded Plastics Over Metals | Moldwel | Plastic Moulding

Much of the success and indeed sustained growth within the Plastics Industry over the last 30 years or so has been down to the use of injection molded plastics in the replacement of metal components. At first there was a great reluctance to change, the majority of designers and engineers had only ever worked with metal and initially were unsure about changing. With ever increasing steel prices coupled with longer lead times and concerns about quality of sourced materials, plastic is now the go to, first choice for the majority when formulating new concepts and designs.

The advantages of Plastics over Metal :

1 – Cost – The cost of Raw Material in Plastics is considerably less than Metal – also production using plastic is far less labour intensive which gives clear savings in energy, wages costs and production time

2 – Weight – plastic weighs considerably less than metal ( despite retaining similar strength properties ) giving savings in component costs and also transport costs

3 – Plastic does not corrode or rust as metal does

4 – Plastic Components can be manufactured in any specific or matched colour – metal cannot – metal has to be painted or coated as a secondary operation, increasing production time and cost

5 – Design – plastic can be manufactured easily in any design, shape or texture irrespective of complexity – metal cannot

6 – Certainly in the cases of high volume, long production runs, Plastic Injection Moulding is far more efficient and cost effective, quicker and produces less scrap and wastage compared to Metal

7 – There are hundreds of different grades of plastics available all with different properties, strengths etc – metal is far more limited with its options.
