Plastic Injection Molding

Injection moulding uses a ram or screw-type plunger to force molten plastic material into a mould cavity; this solidifies into a shape that has conformed to the contour of the mould . It is most commonly used to process both thermoplastic and thermosetting polymers, with the volume used of the former being considerably higher. Thermoplastics but are prevalent due to characteristics that make them highly suitable for injection moulding, such as ease of recycling, versatility for a wide variety of applications, and ability to soften and flow on heating.

Thermoplastics also have an element of safety over thermosets; if a thermosetting polymer is not ejected from the injection barrel in a timely manner, chemical crosslinking may occur causing the screw and check valves to seize and potentially damaging the injection moulding machine.

we are one of the pioneers in the field of Plastic injection moulding in Germany.

Plastic Injection Molding History

What is plastic, this substance that has reached so deeply into our lives? The word comes from the Greek verb plassein, which means "to mold or shape." Plastics have that capacity to be shaped thanks to their structure, those long, flexing chains of atoms or small molecules bonded in a repeating pattern into one gloriously gigantic molecule. "Have you ever seen a polypropylene molecule?" a plastics enthusiast once asked me. "It's one of the most beautiful things you've ever seen. It's like looking at a cathedral that goes on and on for miles."

Injection-molding machines—now standard equipment in plastics manufacturing—turned raw plastic powders or pellets into a molded, finished product in a one-shot process. A single machine equipped with a mold containing multiple cavities could pop out ten fully formed combs in less than a minute.

Many of the new thermoplastics at one time or another found their way into combs, which, thanks to injection molding and other new fabrication technologies, could be made faster and in far greater quantities than ever before—thousands of combs in a single day. This was a small feat in and of itself, but multiplied across all the necessities and luxuries that could then be inexpensively mass-produced, it's understandable why many at the time saw plastics as the harbinger of a new era of abundance. Plastics, so cheaply and easily produced, offered salvation from the haphazard and uneven distribution of natural resources that had made some nations wealthy, left others impoverished, and triggered countless devastating wars. Plastics promised a material utopia, available to all.
