Colours and Additives for Plastic Injection Moulding

  One of the many advantages of plastics is the ease with which they can be coloured.  Whether for cosmetic or functional purposes, it is possible to match any colour to achieve the desired result in a finished part.  There are a range of possibilities when it comes to colouring the material depending on the stage that the colour is added.  Options include compounding, where the base material …

Focus on Ultrasonic Welding

  Ultrasonic welding is a process that uses high-frequency mechanical vibrations to generate sufficient heat to create a bond between parts of the same or similar materials.  Extensively used to join thermoplastic parts, including to some extent glass filled thermoplastics, the process can even weld a number of metals including aluminium and copper.  This technique provides a permanent altern …

Avoiding Fastenings with Moulded-in features

  Plastic moulding methods often require post processing or additional fastenings to assemble parts together once they have been moulded.  The  injection moulding process however, lends itself to the mass production of more detailed and complex shapes, allowing designers to incorporate fixing methods directly into the part itself.   Advantages:  Reduces the required number of components and m …

Top 10 Benefits of Plastic Injection Moulding

Plastic Injection Moulding is one of the most prevalent methods for mass producing plastic components.  The technology involves the feeding of plastic material into a heated barrel.  The material is mixed and then forced into a mould cavity, where it takes the shape of the cavity and solidifies into the final product. Plastic injection moulding has a multitude of benefits over comparative plastic …
