What is injection moulding?
With injection moulding production process you are no longer stuck with 2D designs. Not to mention the considerable savings of time and money achieved with this automatized mass-production friendly process.
Thermoplastic PREPERM® materials are easily processed with conventional plastics processing method. This is one of the key factors behind the statement "best-fit material". Injection moulding enables easy and fast production of complex 3D shapes and sizes. Antenna designs are no longer limited to 2D dimensions - the only limits are set by the imagination.
Injection moulding is a manufacturing process where a part is manufactured by transferring molten plastic into a mold and cooling it down. It is most commonly used to process thermoplastic polymers. Thermoplastics are highly suitable for injection moulding because of the ease with which they may be recycled, their versatility allowing them to be used in a wide variety of applications and their ability to soften and flow upon heating.
3D challenge of the traditional HF materials
Producing 3D shapes with traditionally used high frequency materials is somewhat complicated. Ceramic materials are sintered and mechanically processed to 3D shapes. The production is time consuming and sintered ceramics are typically brittle.
Thermoset materials are often used in planar circuit board structures, since mechanical machining is the only way to make 3D shapes out of thermoset materials. This is complex and time consuming not to mention the non-recyclable material waste generated.
