Especially\u00a0when\u00a0the size of the part to be produced is very small\u00a0and the\u00a0mold\u00a0has\u00a0only a few\u00a0cavities. Or one of the additives does not need more than a single pellet per cycle.\u00a0For those situations\u00a0current\u00a0dosing systems\u00a0available in the market simply\u00a0do not give the required\u00a0consistency.\u00a0Whether this is in color masterbatch or in any other\u00a0not visible\u00a0additive but\u00a0of great\u00a0significance\u00a0in the\u00a0end product. And we must\u00a0admit:\u00a0even our highly accurate gravimetric dosing system\u00a0MCBalance,\u00a0which\u00a0is the\u00a0highest standard\u00a0in gravimetric dosing,\u00a0cannot dose\u00a0pellet by pellet.<\/p>\n

So,\u00a0in practice,\u00a0when you recognize yourself in one of the above situations, you often fall back on manually mixing with all the associated disadvantages.\u00a0As a leader in dosing\u00a0technology,\u00a0we have therefore challenged\u00a0ourselves\u00a0to come up with a solution for this complex dosing issue.\u00a0Might be you have\u00a0already\u00a0been looking for new solutions in the volumetric and gravimetric dosing equipment market, but have you ever thought or heard about\u00a0the term \u201coptometric dosing technology\u201d?<\/p>\n

Optometric dosing technology: what is it?<\/h2>\n

When it comes to dosing additives with an accuracy of one single pellet, both volumetric and gravimetric systems are not suitable. This is because volumetric systems do not measure anything and therefore simply do not know how many pellets it is dosing during a cycle. Gravimetric systems on the contrary do measure exactly the amount dosed per cycle but this is based on the loss-in-weight principle, and not downsized to the level of\u00a0pellet-by-pellet\u00a0detection.<\/p>\n

So,\u00a0there is a natural \u201cgap\u201d between dosing nothing and dosing the lowest measurable amount based on loss-in-weight technology. Wouldn’t it be genius to have a system that could actually ‘see’ one single pellet and by that can close that gap?\u00a0In 2018 this\u00a0made\u00a0us\u00a0decide\u00a0to design and build a dosing\u00a0system\u00a0that\u00a0is capable of dosing\u00a0additives based on\u00a0number of pellets.\u00a0It\u00a0started from scratch and resulted in the introduction of\u00a0world\u2019s first optometric\u00a0dosing system called\u00a0MCNexus. The\u00a0MCNexus\u00a0uses an optical sensor to detect a single pellet. And now, more than 3 years after launching it on the market and listening to customer feedback, the\u00a0MCNexus\u00a0has dotted\u00a0the\u00a0i’s.<\/p>\n

Optometric dosing technology: how does it work?<\/h2>\n

So how does the\u00a0MCNexus\u00a0exactly work? The\u00a0MCNexus\u00a0is equipped with a\u00a0rotating disk driven by an accurate stepper motor. This combination\u00a0picks up single\u00a0additive\u00a0pellets\u00a0in a frequency that you need for your production. The pellets are\u00a0collected by a vacuum and released from that when they reach the point of dosing.\u00a0The disk comes in 3 sizes,\u00a0each of them suitable for a certain range of pellet sizes.<\/p>\n

The unit itself is equipped with\u00a0optic pellet sensors that ensure that dosing frequency is not disturbed. In case such a sensor\u00a0is detecting an empty hole in the disk\u00a0(missing pellet), the disk will quickly rotate forward to\u00a0bring in and release the next coming pellet instead.\u00a0This optometric measure and control system is extremely fast and repeatable compared to any gravimetric loss in weight system.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>
