By getting to know this type of error, Unika has also seized the opportunity to remove NVA steps from this VSM. We installed a conveyor belt divider, with reduced drop height from the tape and down in the boxes. The solution also helps our own employees, by placing the counter at the tape, so that when the desired number gently falls in the box, the divider automatically turns to the next box. The frequency of box changes has developed from two to four boxes. Nevertheless, we have been able to improve the flow, by placing the subject counter and accurate check-weight directly by the tape, so that the number of items per box immediately verified and afterwards is send directly out to shipment.

Reuse of excess material

There will often be material waste in connection with plastic injection moulding of small items, as the channels is filled with the plastic material in several cavities and that is inevitably.

This excess material is seperatet from the items and comes out of another line over in a box. We grinder the excess material. It all takes place "In house" at Unika, so we avoid external transport and grinder costs.

To comply with the quality and safety requirements of the precast item, a permitted percentage is exactly  specified. The grinded excess material is accurately mixed with new material. By always applying a set percentage, Unika has been able to improve its process stability. Together with documentation of stable accurate dosage, we have also been able to increase the proportion of recycled material in cooperation with the customer - successfully!
