Searching New designs Top quality At low cost HOW CAN WE FACE THE MARKET REQUIREMENTS?
WHAT TO DO When the market is asking for: Stemware with thin and long stem Open shape Tumbler with polygonal design……..
WHAT TO DO When the market is asking for:
MARKET AND ORDER BOOK PRODUCER INTERNAL IMPROVEMENT TEAM Major Targets: Trying to improve the productivity by itself Avoiding any expenses And finally Contacting the potential suppliers if no internal solution has been found.
►Producing new design at same costs ►Improving productivity on existing products That means: increasing the production speed 30-50-60-75-100 pcs/min with same or less labour costs Keeping or improving the efficiency Ability to process all kind of products with same performances Reducing the uncontrolled factors as human factor Stabilising repetitive sequences and reproductible set-up Improving equipment reliability THE CHALLENGE OR CHALLENGES
The efficiency of a production line is the results of the multiplication of the efficiency of each processing steps composing this line. 90% x 90% x 90% x 90% x 90% = 60 % THAT MEANS IMPROVEMENTS IN EACH MANUFACTURING STEPS Raw material constancy Glass melting Blowing Press Annealing Finishing Packing THE CHALLENGE OR CHALLENGES
Specialized companies can be found in any segment of the production line BUT The major concern for the IMPROVEMENT TEAM would consist in determining the best partner for the corresponding segment. BIEBUYCK In the rim processing THE CHALLENGE OR CHALLENGES

RIM PROCESSING OF TABLE WARE Mechanical Moil cracking-off: A tungsten carbide wheel applied elastically on the glass surface. In some cases, the scribing can be made with a diamond disc. Burners achieve the process by creating stresses in the cutting area. 2 scribing devices are available: Classic TSD
RIM PROCESSING OF TABLE WARE • MECHANICAL Moil CRACKING-OFF • ADVANTAGES • Relatively cheap solution • Mechanical assembly • Easy to use • Easy to understand • Easy to repair • INCONVENIENTS • Limited efficiency mainly with shaped glasses • No warning when worn out • Limited and no regular life time • Determinant human factor • May damage the diamond tools

RIM PROCESSING OF TABLE WARE LASER MOIL CRACKING OFF A CO2 laser beam is applied under certain sequences to scribe the glass surface. No Burners are required to achieve the process.
THE RIM PROCESSING OF TABLE WARE • LASER MOIL CRACKING OFF • ADVANTAGES • Better efficiency on all kind of designs • Regular cuts even on irregular surface • Wider in glass tolerances • Easy to use via PC and datas • INCONVENIENTS • Investment • Complex installation • Require data control • Safety

The operating costs based on : S2TC37 mechanical and S2TC31 laser. Production speed : 35 pcs/min Efficiency difference: 2 % TSD Scribing and diamond tools. LASER G2 2 x 200 w and 2 x 100 w. and diamond tools Electricity S2T31 L including chiller and dust exhauster Electricty S2TC37 including hydrogen oxygen generator Water and additives OPERATING COSTS MECHANICAL / LASER
OPERATING COSTS: SCRIBING/ LASERCUTTING Scribing wheels lifetime: 13 000 PCS Laser refill: 16 000 Hours. Cutting depht may be reduced when cutting with laser: Scribing : 1,2 mm Laser : 0,8 mm Less Tools damages due to better laser cutting
OPERATING COSTS: SCRIBING/ LASERCUTTING RATIO BETWEEN SCRIBING AND LASER: 7,8 % in favour of the scribing.
OPERATING COSTS: POWER CONSUMPTION S2TC31L –S2TC37 RATIO BETWEEN SCRIBING AND LASER: 5,7 % in favour of the laser. 0,403 0,380
OPERATING COSTS: WATER CONSUMPTION S2TC31L –S2TC37 RATIO BETWEEN SCRIBING AND LASER: 21,5 % in favour of the laser
RATIO BETWEEN SCRIBING AND LASER: 4,8 % in favour of the laser OPERATING COSTS: conclusions
HOW CAN WE BALANCE THE INVESTMENT BETWEEN THE BOTH TECHNOLOGIES: By designing equipment specifically for the G2 laser S2TC31L instead S2TC37 Compact 9 L2 instead of the Combi 12 Combination of 200 and 100 w lasers . RIM PROCESSING OF TABLE WARE
RIM PROCESSING OF TABLE WARE PRICE BALANCE BETWEEN CLASSICAL AND LASER MACHINES.
RIM PROCESSING OF TABLE WARE PRICE BALANCE BETWEEN CLASSICAL AND LASER MACHINES. Water remains the major consummable Rejects reduction becomes the major pay-back factor

EXAMPLE OF PAY BACK S2TC31Laser AND S2TC37 IN MONTHS REJECTS SAVINGS
RIM PROCESSING OF TABLE WARE THANK YOU FOR YOUR KIND ATTENTION CONCLUSIONS: Consumables are balanced between both systems Less water use Less dust due to less glass grinding Realistic pay-back even on classical glasses Allow the processing of difficult products in reasonnable conditions.
