COLD FORM IMPRESSIONS
A small cotton dam is inserted into the canal at a point just in front of the second bend in the canal.
At this point you may be asked to insert a polysterene block in to your mouth which keeps the mouth and importantly the ear canal in its widest position. We do this to ensure the tightest fit of certain specilaised products.
The laboratory is presently the largest of its kind in Europe.
The technician will then mix the appropriate amount of Room Temperature Vulcanising Silicone (RTVS) and uses a specially designed syringe to fill the ear canal and the entire concha of the ear. When this material sets (approximately five minutes) the moulds are removed from the ear, packaged and taken to the laboratory for manufacture. The laboratory is presently the largest of its kind in Europe and has a capacity for thousands of units a week.
When the moulds arrive at the office they are placed in a specially designed scanning unit that converts the mould into a perfect digital image. This image is then sent to one of the four new Project 3510 MP 3D digital scanners. In an overnight process that takes place in a temperature and pressure controlled secure area the product is produced using the latest Microflex Extreme material.
