Our Products Information
 

BRAVO IMPEX Scissors and Beauty instruments are result of latest manufacturing processes combined with experience of skilled master craftsmen gained over several years. Ours high end styling shears are made to our exacting specifications with the professional end user in mind. These shears must meet the high standards of steel quality and craftsmanship. We only choose the best types of steel to make our shears. These include 440C, J2 420 and other high carbon steels. Ours steels have low impurity content, good tenacity and viscosity, excellent resistance to wear and are fully rustproof. These stainless steel alloys result in blades which are superior in wear resistance, hardness, and dimensional stability.
BRAVO IMPEX premium shears are not cast or made in one piece but instead these shears are carefully welded part by part and hand honed for absolute best performance and durability. Each shear is hand finished by master craftsmen trained in the art of shears manufacturing. They are first forged so that the handle and blade are manufactured in separate molds. They are then welded together by hand to ensure proper balance and exact blade alignment. The blades are sharpened by BRAVO IMPEX own unique method. The scissors blades further undergo a stringent manufacturing process in which they are vacuum-annealed twice and hardened to Rockwell (HRC) hardness range 52-57 depending on the material. This process is more labor and cost intensive but it gives you a much higher quality, lasting and better cutting instruments for years to come.
All other instruments like nippers, cutters and other beauty tools are made from the very finest materials by highly skilled masters. These masters have inherited metallurgical steel knowledge from the local family tradition as it is passed on from one generation to the next. These “Ustads” take personal responsibility for the final cutting and ergonomic feel of individual instruments which are intricately finished by hand.
All instruments are thoroughly inspected and must pass rigorous quality control standards in each stage of the production process. They must also be subjected to final quality control check before they are shipped out.
Our shears have cost advantage over other shears because most of our advertising is done through word of mouth. We sell to distributors, stylists and professionals worldwide directly. We pass these cost savings to our customers by giving them a very high quality product at very reasonable prices.

DESIGN & RESEARCH
Our continuous focus on research has led us to produce different types of blades, tension systems, finger grips and coatings for our customers.
Our Scissors with curved blade impede the sliding of the hair, to compensate the deviation of the cut thus guaranteeing straight lines. Ergonomic scissors with specially designed thimbles diminish the fatigue of the thumb reduce possible injury of tendon.
PVD coating and Tungsten Carbide tipped scissors come with there own unique features and longer lifes.

MATERIALS
Steel Alloys:

Various alloying elements are added to basic steels to enhance corrosion resistance, hardness, toughness and machining characteristics. Carbon is the principal hardener in steel whereas phosphorus and sulfur are present in all steels, usually as impurities. However they are sometimes added in controlled amounts for easier machining. The more carbon is added (up to 1.2%), the harder the steel gets.
Molybdenum is a very important additive as it adds toughness and increases corrosion resistance. Molybdenum inhibits grain growth and lengthens the quench time of steel. This provides for a good stress-free martensitic structure.
Manganese contributes to strength and hardness. Phosphorus also increases strength and hardness, but at the sacrifice of ductility and impact toughness, as its content is increased.
Sulfur in select cases improves machinability and Silicon increases strength and hardness.
Chromium protects against corrosion and adds heat resistance. However all the elements have to be in correct ratios to reach the desired properties in steel and we incorporate these in our materials.

PVD COATING RANGE:

This range of scissors is covered with Titanium Nitride (TIN) by a technique known as PVD (Physical Vapor Deposition). This coating greatly enhances the hardness of the scissors since the hardness value of the TIN layer is something in the order of 2500 Vickers. This is around four times greater than that of tempered steel.
Further the TIN layer gives much better resistance to erosion and to chemical agents as compared to uncoated steel. Corrosion test for this type of coating carried out in saline mist chambers give results even better than those with chrome coating. This coating is normally used in cutting and machining tools since it provides parts with greater resistance to wear and abrasion. Manufacturing and design engineers recognize the benefits of this carefully selected 3 ~ 5 micron coating on tool work surfaces. Tool life increases dramatically, from 50%/100% to much more.
Tungsten Carbide:
Cutting any type of hair is a breeze with BRAVO IMPEX Tungsten Carbide Scissors. They are super-sharp and extra-hard, five times harder than steel. These specially designed scissors are great for precise cutting and trimming.
These specially designed scissors have small carbide insert held in place by a larger scissors made of a less brittle stainless steel. This gives the benefit of using carbide without the high cost of making the entire scissor out of carbide. To further increase the life of carbide scissors, they are sometimes coated with TiN (

titanium nitride).
Following is a brief description of the main processes that are completed within the manufacturing plant in different sections.
Forging:
Hot and cold forging processes are instrumental in giving high quality to the instruments. Hot drop forging is the best process for steel conversion in order to have a high quality tool. This critical process is carried out on red-hot steel cuttings (at 800 to IOOOC), which are hammered by a Hot Forging Hammer (50-300tons).
The Forgings are made through Drop Hammer process by skilled operators using Dyes made of the best-quality D-2 Steel. The forgings later are put through the process of overall ring trimming, and acid cleaning by experienced technicians.
What is a drop forged shear?
Pieces of steel are heated up red hot and put in a die that resembles the shape of the shear or tool. First half of the die is attached to the ram which acts like a hammer and the second half is fastened to a big anvil. The ram drops on the steel, forging the pliable steel into the die and giving the steel the initial form of the shear. These drop hammers are up to 15 to 20 feet high and can weigh 1000 lbs or more. They stand on strong foundations for effective working. The material flow of the hot metal being compressed and pounded into the cavity makes the steel structure much denser and makes it strong and durable,
As the shears dimensions are not uniform, some of the hot steel is squeezed out of the die cavity. The resulting large burr is cut off under heavy presses and the still hot shear forgings are carefully cooled to eliminate any internal stress. They are then tempered and trimmed.
Therefore our drop forged tools and shears are far superior to blanked cheap ones in the market.
Milling-Machining:
Extremely high quality milling and machining of ratchets, serration teeth, box cutting and other parts ensure perfection before filing. This involves use of high quality machines and transformation skills of workers gathered over generations.
In order to ensure that the blades meet correctly, the holes must be drilled to within one ten-thousandth of an inch (about one four-hundredth of a millimeter) of the correct position. The position of the blades is inspected visually to see if the blades meet evenly. The most important aspect of quality control for scissors is the proper alignment of the two blades. In order for scissors to cut smoothly, the blades must meet at two points only. These two points are the swivel (the point where the rivet or screw connects the blades) and the cutting point. The cutting point moves from just beyond the swivel to the tip as the scissors are closed. The blades are prevented from meeting at any other points by giving them a slight horizontal and vertical curve away from each other during manufacturing. If not done properly, a portion of one blade will overlap the other and scissors would be rejected.
These processes play a key role in the final outlook and quality of instruments.
Heat Treatment:
Our use of advanced heat-treating technology safe guards the purity of the stainless steel and the resultant crystal-line structure of scissor blades and other instruments cutting surface is second to none.
The basic purpose of heat-treating is to radically change the molecular structure of the steel, while retaining as many of the original characteristics of the alloy as possible. Correct heat treatment further provides for oxidation reduction of carbon contents in stainless steel during the manufacturing process. This helps to overcome problems like warping, cracking and coarse grain.
Hardening & Tempering:
Further hardening of a stainless steel by austenitizing and then cooling rapidly transforms some or all of the austenite to martensite.
Tempering involves reheating the quench hardened ferrous alloy to a temperature below 650C and then cooling at the desired rate. The tempering treatment modifies the martensitic structure of a quenched hardened casting to ferrite with precipitated carbides.
Steel in it’s "as-quenched" Martensitic form, is hard and brittle, with pockets of retained Austenite. To relieve the quenching stresses and to provide the required but controlled degree of toughness and ductility the hardened steel must be subsequently tempered. This eliminates the cracking risk as carbon will precipitate, forming Carbide clumps with large areas of soft Ferrite in between. The higher the temperature and longer the exposure the more is steel stress relieved and softer it becomes.
We temper our shears keeping in view the requirements of the steel being used and desired hardness and toughness. For high alloyed steels we use multiple tempering as it is more effective than a single tempering. The second tempering stress relieves the retained Martensitic from first tempering.
Grinding and Electro Polishing :
The desired results of Product's Outlook are obtained by seasoned workers using different kinds of grinding wheels and scissors. Scissors and all other Cutting Instruments also undergo the EGP- Edge Grinding Process.
The blades are meticulously hand-honed and assembly set by the "USTAAD" in a laborious, time-consuming process. They are finished to masters own personal high standards until they become a perfect and flawless matching cutting set. Every surface is hand polished to achieve a flawless mirror finish. These combined elements represent the highest expression of technology and craftsmanship.
Passivation:
All instruments go through passivation and are tested for corrosion test to ensure instruments stay rust free for life.
High quality Sandblasting and Stamping/Etching is carried out with perfection on instruments requiring these elements. Finally each instrument is checked for smooth movement, polishing requirement and for its functional characteristics. After quality control inspection the instruments are further rebuffed and thoroughly cleaned for superior results.
Instruments then go through final inspection, where each and every instrument is judged by quality control staff with an eye of an internal customer. Instruments are then packed carefully for final shipping.
Scissors Hardness :
BRAVO IMPEX scissors are usually made in 420 and 440 stainless steel series as compared to many inexpensive stainless scissors that are made from 410 Stainless Steel. The 410 stainless steel has excellent corrosion resistance and is easy to work with, but will harden to only 38-44 Rc. As a result these scissors edge would not have long life and they also usually bend easily.
Most of the better scissors like ours are made in 420 series which was one of the first stainless steels developed for the cutlery industry. It has the advantage that it hardens to 48-55 Rc and has good ductility and toughness. The general hardness range for these scissors is around ~51-52 Rc because in this range the blades can be bent and set, without the risk of breakage.
Our premium 440 series of stainless steels series quench to a Rockwell between 56-62 Rc. Tempered, they usually perform the best in the 54-57 Rc range. At Rockwell 57+ they can become very brittle.
Hardness Tests - A Rockwell hardness tester measures the difference in the depth of penetration of a diamond or steel ball tipped penetrator subjected to a minor (initial) and a major (final) load under specific conditions. The deeper the diamond penetrates, the softer the material is. The penetration is approximately 0.00008 inch per Rc point.
