|
|
Jaivic Electromech Engg. Pvt. Ltd. are very well known as Quality Leaders in Power Factor Correction Capacitors in India. In keeping with Company's philosophy to manufacture Quality Products, Jaivic has installed Modern Capacitor Film Metallising Plant manufactured by Aerre Machine, SrI. Italy. The Production of Film, Slitting, has been installed as per European standards. Quality Control levels and Vacuum Packing have been fully established under the close supervision of Highly Technical Personnel having experience of more than 30 years in this field. |

- Jaivic offers MPP (Metallised Polypropylene) and Metallised Polyester (MPET) film to manufacture Capacito~Jaivic has versatile technology which can produce TRI-LAYER HEAVY EDGE Zn-Alloy
Metallisation uSing~n.sAluminium and Silve9'in addition to only Aluminium Metalisation. The 3-
Layer construction overcomes the shortcomings of conventional types of metallisation and combines the desire quality of higher stability obtained from Zinc and Longer shelf life of Aluminium Metallised Film.
- The function of Silver adds to improve adhesion of Zinc to the Base Film. This strong bonding / adhesion can't be achieved by any other manufacturer, who
do not use Silver. (due to limitation of their plant and to reduce their cost by sacrificing the quality.)
- 3-Layer Zinc...:..Alloy Metallisation with reinforced edge facilitates superior end spray adhesion, thereby improving the surge withstanding capability of sprayed elements.
- Only Aluminium Metallisation normally required for BOPP or Polyester Film used in DC Applicatio for easy handling or Capacitors manufactured with Oil
Impregnation.
- To overcome Demerits of AI and Zn metallised film, Multilayer Metallised Film with Coating of AI, Ag.
Zn AI on the same Film solves the problem of rapid Oxidisation of Zn but maintaining all the merits of Zn.
- Rounded corners near the free margin, generated by oil evaporation, prevent excessive electric stress.
- Deposition of Aluminium with vaporisation from independent Aluminium boats, gives uniform metallisation over the film width.
- Consistent high quality, due to continuos in-process monitoring of various parameters of the metallising process and the machine.

The above tests are carried out in addition to the Metalliser has its own, fully automated, in process quality control which continuously monitors and controls parameters like resistivity, regeneration / clearing per unit film area, vacuum level, winding tension, speed of metallisation average temperature etc. A printout is available at every 500 mtrs. run of the film through the Computer which is a part of Metallisation. |
 |
Slitting of the metallised rolls is done on servo-controlled slitting machines in a Air conditioned environment with strict control on temperature, humidity and dust. Slitting width is controlled with the help of optical sensors which continuously adjust the film position with respect to the cutting blades. The resulting slit film reels have an extremely sharp edge with very low tolerance. This helps to improve the quality of end-spray and reduce incidences of capacitor terminal shorts. |
