  1. Mirror Manufacturing Production from glass to mirror www.deknudtmirrors.com

  2. Mirror Manufacturing Mirrors made by Deknudt Mirror Works : 1. Quality of the glass: Usage of “fresh” glass coming out of the ovens of the best European glass manufacturers 2. Silvering on own silver conveyor 3. Specialised in mirror (double sided, silk-screen printing, edge finishing,…) 4. Respect for the environment (no lead, purification installations,…) 5. Completely conform all strict EU-norms (ISO 9001) www.deknudtmirrors.com

  3. Mirror Manufacturing Technical info about maximum dimensions : Thickness of the glass : maximum 8 mm dikte Silver conveyor : maximum 1120 mm wide Printing : glass size : max. 2040 x 1150 mm plain printing : max. 2030 x 1065 mm sandblasting : max. 1840 x 965 mm quadri : max. 666 x 400 mm Durorolls : maximum 1900 x 685 mm www.deknudtmirrors.com

  13. Mirror Manufacturing Step 1. Glass preparation : Clean with waterThorough rinsing and polishing with Cerium oxide 9 Batteries with 12 turning brushes eachDrying and heating up to about 30 °C www.deknudtmirrors.com

  14. Mirror Manufacturing Step 2. Sensibilisation and activation : For a good attachment of the liquid silver on the glass surface.Sensibilisation : A tin oxide solution is sprayed on A little further, it is rinsed off as well Activation : Palladium Chloride solution on the surface a little further the surplus is sprayed off www.deknudtmirrors.com

  15. Mirror Manufacturing Step 3. Silvering : Liquid silver is equally divided over the glass surface by means of a spraying curtain. (1 micron = 1/1000 of 1 mm) www.deknudtmirrors.com

  16. Mirror Manufacturing Step 4. End of precipitation reaction : After 30 seconds the precipitation reacton of the liquid silver is finished. The surplus is sprayed off and the chemical reaction is stopped. www.deknudtmirrors.com

  17. Mirror Manufacturing Step 5. Passification : Silver layer is treated with a layer of tin chloride soluiton. Also that one is rinsed of a little further In this way, the use of an environmentally unfriendly cupper layer can be avoided. = Green Mirror Deknudt ! www.deknudtmirrors.com

  18. Mirror Manufacturing Step 6. 1e pouring curtain of protection lacquer : 1st layer of protection lacquer on the silver layer (20 micron) www.deknudtmirrors.com

  19. Mirror Manufacturing Step 7. 1e Drying oven : Mirror runs through a 1st drying oven to let the protection lacquer slowly dryTemperature : 90°C - Duration: 4 minuten. www.deknudtmirrors.com

  20. Mirror Manufacturing Step 8. 2nd pouring curtain of protecting or glueing layers : 2nd lacquer layer on top of 1st protection layer:Regular mirror : 2 x^protecting layer Double sided mirror : glue lacquer (thermoplastic glue) www.deknudtmirrors.com

  21. Mirror Manufacturing Step 9. 2nd drying oven : The protected mirror runs through a 2nd drying oven to let the 2nd layer slowly dry.Temperature: 180°C - Duration : 4 minuten www.deknudtmirrors.com

  22. Mirror Manufacturing 10. Waiting trolleys in the production After drying and quality control, the mirrors are put on waiting trolleys, in expectation of the next process and in the mean time cooling down www.deknudtmirrors.com

  23. Mirror Manufacturing Silk screen printing : Step 1 : Preparation : Glass is put on the machine, thoroughly rinsed and dried www.deknudtmirrors.com

  24. Mirror Manufacturing Silk screen printing : Step 2 : Printing : Glass goes under screen Paint is spread over the the sieve. Paint only goes through tiny holes in the sieve . www.deknudtmirrors.com

  25. Mirror Manufacturing Silk screen printing: Step 3 : Oven : Printed mirror goes through drying oven: 3 min. à 120°C www.deknudtmirrors.com

  26. Mirror Manufacturing Silk screen printing : Step 4 : Quality control printing quality : Final check of the printing quality. Mirror put on waiting trolley for further processing. www.deknudtmirrors.com

  27. Mirror Manufacturing Durorolls / Double sided mirror :Step 1 : Preparation :Mirrors with thermoplastic glue in the upper lacquer layer are layed down back to back www.deknudtmirrors.com

  28. Mirror Manufacturing Durorolls / Double sided mirror :Step 2 : Through oven :Mirrors go through an oven of 110°C : both glue layers become plastic and get fixed to each other www.deknudtmirrors.com

  29. Mirror Manufacturing Durorolls / Double sided mirror :Step 3 : Pressing and cooling :Mirror plates are pressed together by 12 consequent pressing rolls. Cold water is poured through the rolls, which makes the mirrors cool down slowly and hardens the glue. www.deknudtmirrors.com

  30. Mirror Manufacturing Durorolls / Double sided mirror : Step 4 : End control :Mirrors are now permanently glued to each other. Quality control and putting them on a waiting trolly for further processing. www.deknudtmirrors.com

  31. Mirror Manufacturing Cutting to final correct size Drilling holes www.deknudtmirrors.com

  32. Mirror Manufacturing Edge finishes : ChamferGrinding the sharp corners F-grindingmat of polished C-grindingmat of polished Classic bevel e.g. 25 mm on 7° Modern bevele.g. 7 mm on 30° www.deknudtmirrors.com

  33. Mirror Manufacturing Edge finishes : Unprocessed cut glass edge ChamferSharp corners removed www.deknudtmirrors.com

  34. Mirror Manufacturing Edge finishes : F-grindingmat or polished C-grindingmat or polished www.deknudtmirrors.com

  35. Mirror Manufacturing Edge finishes : Classic bevel e.g. 25 mm on 7° Modern bevele.g. 7 mm on 30° www.deknudtmirrors.com

  36. Mirror Manufacturing Edge finishing machine (linear = 1 side at a time) www.deknudtmirrors.com

  37. Mirror Manufacturing Edge finishing machine (double sided linear = 2 sides at a time) 2 sides horizontally and in the middle 90° turn for vertical sides== > 4 x quicker than linear edge finishing www.deknudtmirrors.com
