                            of passion for dynamic weighing
                                                                          years

                                   NEMESIS is an Italian company located in Modena, North of Italy.
                          Since 1976 is active in the industrial automation field developing dynamic weighing
                                              technologies mounted on HSC350 machines.

That’s what we do.
                  Better than you can imagine.
                    NEMESIS core business is design, project and build checkweighers. We do not pretend to
                  have hundreds of machines in our portfolio, we just do what we know very well and we do it
                                             with the very forefront technologies.

Checkweighers give you control
                          A checkweigher is an automatic machine able to weigh dynamically every item of a
                                  production line sorting and/or rejecting it according its weight.

0,5%
                          Is manual sampling significative?

                   Manually sampling 24 items per hour with a throughput of 100 items per minute gives you
                                           a 0,5% control over the full production.

                   It’s a really insignificant control on the quality and it has huge costs in term of time and
                                                            manpower.



mercoledì 31 ottobre 12
100%
                                         This is significative.

                     The key value of a checkweigher is to control 100% of the production. It records data for
                    every single item passed through your line for statistical and process-quality analysis .

                              after preparation    statistical reports.




                          It does more than you expect.

Why choose HSC350?




                              Italian style, Italian quality.
                     Our machines are fully designed and assembled in Italy using only the best quality
                  components. We do a very intensive test session: 24 hours a day, 7 days a week for not less
                                                       than 3 months.

                          Forefront of weighing technology
                     NEMESIS invest every year 50% of its resources on Research & Development. In the last 6
                    years we reinvented the product 4 times with an average lifecycle of only 18 months. And
                                           we still give full support to older products.


mercoledì 31 ottobre 12
As easy as a click.
                           We know that time is money. Our first rule while developing software interface is to
                          produce something extremely easy and intuitive to use: we don’t want you waste time
                                                    learning difficult procedures.


mercoledì 31 ottobre 12
Not last, we are 100% certificated

                      HSC350 equipments are fully certificated according Italian decree, OIML R-51 and MID
                                    directives up to 60 kg in all different configurations.

What is peak weight?
                      It’s a very diffused but old technology, most manufacturers are still using it inside
                  checkweighers. It measures the value of weight in the “peak” part of the signal coming from
                                                          the load cell.



mercoledì 31 ottobre 12
Certificated only for   Requires expensive
                           few products clearly   and long calibration
                           shown in the plate     procedures




                           Badly affected by      Requires a dynamic
                           wind, temperature,     factor to correct the
                           vibration...           weigh measure




                          It doesn’t look so good.

mercoledì 31 ottobre 12
What is real weight?
                    It’s a new weighing technology by HSC350 that uses sophisticated algorithms to measure
                    the weight. Checkweighing has never been so easy and quick. No more calibration or any
                                                manual operation...it just works.



mercoledì 31 ottobre 12
Do I have to worry about calibration?
                          Do I have to worry about wind, vibration, temperature?

                             Do I have to worry about shapes or orientation?

                                 Do I have to worry about new products?

                                Do I have to worry about dynamic factor?

                               Do I will miss a peak weight checkweigher?




             With real weight, you don’t have to worry

Checkweighers HSC350

  • 1. HSC350 by Nemesis Your opinion of checkweighers will never be the same. mercoledì 31 ottobre 12
  • 2. 36 of passion for dynamic weighing years NEMESIS is an Italian company located in Modena, North of Italy. Since 1976 is active in the industrial automation field developing dynamic weighing technologies mounted on HSC350 machines. mercoledì 31 ottobre 12
  • 3. That’s what we do. Better than you can imagine. NEMESIS core business is design, project and build checkweighers. We do not pretend to have hundreds of machines in our portfolio, we just do what we know very well and we do it with the very forefront technologies. mercoledì 31 ottobre 12
  • 4. Checkweighers give you control A checkweigher is an automatic machine able to weigh dynamically every item of a production line sorting and/or rejecting it according its weight. mercoledì 31 ottobre 12
  • 5. 0,5% Is manual sampling significative? Manually sampling 24 items per hour with a throughput of 100 items per minute gives you a 0,5% control over the full production. It’s a really insignificant control on the quality and it has huge costs in term of time and manpower. mercoledì 31 ottobre 12
  • 6. 100% This is significative. The key value of a checkweigher is to control 100% of the production. It records data for every single item passed through your line for statistical and process-quality analysis . mercoledì 31 ottobre 12
  • 7. Check for Discard, sort missing items overweight and or components. underweight items Check the fill of Measure efficiency of liquids before and production lines with after preparation statistical reports. It does more than you expect. mercoledì 31 ottobre 12
  • 8. Why people buy checkweighers Comply the big Comply the law customer requirements requirements is this the only reason? mercoledì 31 ottobre 12
  • 9. Production speed 220 ppm Gram’s price € 0,0030 0,5 g overfill per € 0,0015 / prod. product Cost per minute € 0,33 Cost per hour € 19,80 € Cost per day € 316 (2 shifts) How much 0,5 g cost to you? mercoledì 31 ottobre 12
  • 10. 72.864 € per year Checkweighers make you money. We know that every single gram of your product really worth to you. That’s why we are focusing our research and development to achieve the highest accuracy ever. We don’t guess the weight, we really measure it. mercoledì 31 ottobre 12
  • 11. Avoid manual and Do not risk customer non significative relationship operations Improve the Avoid costly fines and efficiency of your respect the law production line That’s why you should buy it. mercoledì 31 ottobre 12
  • 12. Why choose HSC350? Italian style, Italian quality. Our machines are fully designed and assembled in Italy using only the best quality components. We do a very intensive test session: 24 hours a day, 7 days a week for not less than 3 months. mercoledì 31 ottobre 12
  • 13. 50% Research & Development Forefront of weighing technology NEMESIS invest every year 50% of its resources on Research & Development. In the last 6 years we reinvented the product 4 times with an average lifecycle of only 18 months. And we still give full support to older products. mercoledì 31 ottobre 12
  • 14. As easy as a click. We know that time is money. Our first rule while developing software interface is to produce something extremely easy and intuitive to use: we don’t want you waste time learning difficult procedures. mercoledì 31 ottobre 12
  • 15. Not last, we are 100% certificated HSC350 equipments are fully certificated according Italian decree, OIML R-51 and MID directives up to 60 kg in all different configurations. mercoledì 31 ottobre 12
  • 16. What is peak weight? It’s a very diffused but old technology, most manufacturers are still using it inside checkweighers. It measures the value of weight in the “peak” part of the signal coming from the load cell. mercoledì 31 ottobre 12
  • 17. Certificated only for Requires expensive few products clearly and long calibration shown in the plate procedures Badly affected by Requires a dynamic wind, temperature, factor to correct the vibration... weigh measure It doesn’t look so good. mercoledì 31 ottobre 12
  • 18. What is real weight? It’s a new weighing technology by HSC350 that uses sophisticated algorithms to measure the weight. Checkweighing has never been so easy and quick. No more calibration or any manual operation...it just works. mercoledì 31 ottobre 12
  • 19. Do I have to worry about calibration? Do I have to worry about wind, vibration, temperature? Do I have to worry about shapes or orientation? Do I have to worry about new products? Do I have to worry about dynamic factor? Do I will miss a peak weight checkweigher? With real weight, you don’t have to worry mercoledì 31 ottobre 12
