PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - "TAMPER PROOF SEALING" r The invention relates to a temper proof seal made from polycarbonate plastic material and having stainless steel twisted wire moulded itself in temper proof seal male and female part. ORDINERY PLASTIC/ LEAD SEALS Ordinary seals are made up of PP or HDP material having no UV resistance. Plastic/Lead seals are opaque so inside tempering cannot be easily visible. a) Easy to tamper b) Tamper attempts are not easily evident c) Easy to re assemble usually Single wire d) One can cut and change seal wire easily e) Plastic seals can withstand to 120° C so it can be easily tamper by boiling Consecutive numbering is tough to do on lead seals. General plastic seals have printed or itching type number on male or female portion of the seals and it can be easily duplicated. Cheaper plastics quickly deteriorate due to weather and other harsh conditions lead seal suffer from corrosion made from single plastic material. Usually low quality. Tool require for lead seals as well as plastic seals. Impossible with lead seals. Ordinary Plastic seals do not offer this level of customization. Therefore there is a need to prevent such tempering of seal, the applicant has device a temper proof seal with double locking system using polycarbonate male female part which are push fit, the male part and the female part are connected by non-corosive and non- magnetic stainless steel wire which are moulded while making the seal To manufacture the temper proof seal first of all we have to pre heat the Polycarbonate plastic materials at 110 °Cin drier for three to four hours before using. And mean time Stainless steel wire is tested first in dimension and acid test and then it is twisted in twisting machine up to desired twist and then it is cut by cutter to required length. First we put pre heated Polycarbonate plastic materials granule in Vertical type molding machine and then mould of seal is been closed by hydraulic pressure of machine and then wire is insert in mould and then material is been injected in mould through moulds machine and hence temper proof seal is got ready. The emboss type numbering arrangement on male and side of female part of the temper proof seal is itself in the mould and the constructive numbering is obtain 2 in all The temper proof seals by automatic arrangement of numerator counter inserted in mould itself. Then these temper proof seals are tested by pullout test, Acidic test and then we shall supply as per client requirements and i.e. arranging in serially, tide with the steel wire forming a loop and the same shall be packed in polythene bag with labels furnishing sr. nos. of seal, packed in corrugated box.

12. Stage inspection:-
If desired by the client, client will arrange stage inspection for the material used for the manufacturing of seal and process of manufacturing.
Accordingly, there is provided a temper proof seal comprising a male part (1) and a female part (2) made form polycarbonate material wherein a twisted double stand steel wire is mouldably connected to the base of the male part (3) and base of the female part (4); said male part having double notch (5) and (6) V-shaped projections and the said female part having complementary groups (7) and (8) to arrest the projected parts (5) and (6) when pushed into the female part thereby permanently locking the male and female part together which have serial numbers and firm name or client logo/name on the male part or inside the female part while moulding which can be seen from outside due to the transparent character of the polycarbonate.

PLASTIC/LEAD SEALS
Material These seals are made up of imported M/S Du Font LV - 20 Grade Polycarbonate material Having UV Resistance. Ordinary seals are made up of PP or HDP material having no UV Resistance.
Transparency These seals are fully transparent so that temper can be easily detected Plastic / Lead seals are opaque so inside tempering can not be easily visible.
Tamper Evident (a) Difficult to temper (b) Any attempt to temper is easily evident(c) Difficult to re assemble 2 strand (a) Easy to tamper (b) Tamper attempts are not easily evident (c.) Easy to re assemble

S.S. non magnetic wire(d) No one can cut and change seal wire as itself is molded in seal (e) Seals can with stand up to 270° C so it can not be tamper by boiling usually Single wire(d) One can cut and change seal wire easily (e) Plastic seals can withstand to 120° C so it can be easily tamper by boiling
Consecutive Numbering Unique consecutive numbering the seals having 7 Digits embossed type number, on male and female part of seals and seals are numbered automatically during molding itself so duplicating is not possible Consecutive
numbering is tough to do on lead seals. General plastic seals have printed or itching type number on male or female portion of the seals and it can be easily duphcated.
Durability UV Resistance of seals life of 5 to 10 years Made from complex then no engineered plastics Cheaper plastics quickly
deteriorate due to weather and other harsh conditions lead seal suffer from corrosion Made from single plastic material. Usually low quality.
Easy to use No tool required for installation. Easy to
apply Tool require for lead seals as Well as plastic seals.
Customization Can be customized with marking nf region / circle as well colour - coded for easy identification. Impossible with lead seals. Ordinary Plastic seals do not offer this level of customizatiol
The invention will now be clear from the Figure (1) in the accompanying drawing.

Figure (1) is the perspective view of temper proof seal.
Referring to figure (1) a male part (1) and a female part (2) with base (3) and (4) respectively made from polycarbonate plastic material wherein the male part having V-shaped projection (5) and (6) with complementary groups (7) and (8) in the female parts for double locking in a push fit maimer said base member (3) of male part and the base member (4) of female part is mouldably connected by a double stand stainless steel twisted wire (9).
Power unity has also started demanding the supply of meters with plastic seal. This type of seals are specially designed for the purpose of meter manufacturer considering easy operation, handling and low cost. The specially designed seals have in built seal wire. Once has to simply insert the seal wire end through hole via meter and insert male part into female part by applying pressure through thumb and it will be fitted permanently. The seal
once fitted can not be removed unless it is broken or cut through sharp object. For sealing of seal no tool is required.
The seals are available in (1) Polycarbonate material and (2) Polypropylene material as per the requirement of the client. The material used in polypropylene seal is of M/s. Reliance Industries Ltd. And for polycarbonate that of M/s. Du -Point, Singapore.
Some of the important properties of polycarbonate material and polypropylene

This is an embodiment of the invention several modification are possible which may be considered within the ambit and spirit of this invention.

We claim:
1. A tamper proof seal comprising
a male part and a female part made form polycarbonate materials wherein a
twisted double strand steel wire is mould ably connected to the base of the
male part and base of the female part;
said male part having double notch and V-shaped projections and the said
female part having complementary grooves and to arrest the projected parts
and
when pushed onto the female part thereby permanently locking the male and
female part together which have serial numbers and firm name or client
logo/name embossed on the male part or inside the female part while
moulding wherein the emboss type numbering arrangement on male and side
of female part of the tamper proof seal is itself in the mould and the
constructive numbering is obtained in all the tamper proof seals by automatic
arrangement of numerator counter inserted in mould itself. These embossed
numberings and logo are seen from outside due to the transparent of the
polycarbonate.
