Nickel is a heavy metal elements likely cause of allergy in human’s skin. Medical observation proves that long-term exposure to nickel-containing objects can cause skin allergies and even cancer. Excessive amount release of nickel in metal eyewear can result in harm to human health. International Organizations and the European standardization organization (CEN) have strict management measures on this.

EU countries have strict rules and standards for metal eyewear. Metal eyewear won’t allow to sale to consumers with excessive nickel release amount. In June 1994, EU issued a 94/27/EC directive, providing standard for release amount of nickel. In July 1997, the EU released 3 harmonized standards, defines the method of a qualitative analysis of nickel amount of release. ISO/TS24348 method for detection of nickel release in 2007 of the officially promulgated, which expressly provides that: Metal eyewear with the wearer’s skin and prolonged exposure to nickel and alloy components of release amount shall less than 0.5μg/ｃ㎡/week.

To be issued by the ISO12312-1 of the sunglasses are a direct reference to the provisions and requirements: Sunglasses designer and manufacturer shall not endanger the health or safety of the wearer, and should minimize the risk of possible damage the wearer’s skin by the lens or frame material.

Korea technical standards (KATS) published belongs to the proposed modifications to the safety and quality mark for industrial products, this proposal seeks to amend the safety and quality standard in sunglasses and optical fame, the release of nickel for sunglasses and optical frame to adjust to less than 0.5μg/ｃ㎡/week.

From the current status, Chinese eyewear products accounted for more than 70% of the world’s total eyewear production amount, and exports more than 60% to the international eyewear market. However many domestic manufacture of metal eyewear adopts low cost of nickel plating.
Since International Organizations (ISO) and the European standardization organization (CEN) have new stringent requirements of release amount of nickel, which brought a great impact on domestic eyewear industry, it becomes necessary for well understanding production method for the detection of nickel release.

As a professional metal eyewear manufacturer, we adhere to the ISO and European Organization for Standardization (CEN), we cooperate with quality electroplating factory and signed contracts and agreements related to the nickel release test. Each batch of metal eyewear should pass through the nickel release test.

Just share one beautiful buffalo horn eyewear model.

Hot style, looks like Moscot shape, purely natural buffalo horn.

This model is quite classic buffalo horn eyewear. Someone like it?

Titanium eyewear is in fashion now, because titanium eyewear has many excellent properties

1, light weight, about 40% lighter than stainless steel eyewear and nickel silver eyewear.

2, High hardness, about twice hardness to other metal eyewear such as stainless steel eyewear and four times hardness to ordinary nickel silver eyewear, In the cryogenic world, titanium eyewear has become more hard, and have the properties of superconductors, the stainless steel eyewear becomes weak and incompetent.

3, Corrosion-resistant, won’t rust. Titanium eyewear won’t rust soak in the sea water for 5 years, stainless steel eyewear must corrosion in sea water.

4, Touches and feeling good, Titanium eyewear warm and silky to the touching, other metal eyewear has cold metallic feeling.

5, No skin allergy, titanium eyewear does not produce allergic reactions to humans skins, also titanium is used in human body, such as artificial teeth, artificial bones.

Titanium eyewear because of its light weight, corrosion resistance, and non-allergic quality features has becomes a new trend. But compared to other metal eyewear, acetate eyewear, titanium eyewear price is much higher.

Why the Titanium eyewear is expensive?

One reason is the current titanium raw material costs are too high

The other reason is the production of titanium metal frames is very complex

The production of titanium eyewear requires special processing equipment, special welding technology and electroplating technology, many high difficult and different processes with normal metal eyewear, so it with high production costs.

With the emergence of new titanium eyewear production equipment, as well as the improvement of industry production and processing technology, titanium eyewear will become lower prices to a wider people.

Metal eyewear is completed by using the welding machine, with about 40% to 69% the purity of silver brazing wire welding. Welding group main process: welding rim lock→ open rim lock→ welding metal bridge →welding cross bridge→ welding nose arm→ welding hinge→ welding spring hinge box→ welding frame, What can we do if any part of metal eyewear was broken?

During the metal eyewear producing process, the metal eyewear was welded in the mould. The mould main function is to ensure accurate position of welding on metal frame. The welding machine through instant high temperature to melt metal and put pressure on the two metal parts together and so it does not harm the original shape.

Generally, weld broken metal eyewear almost belonged to damaged, It is not to say cannot rework the welding, but it will completely destroyed plating layer when welding, it is hard to weld in a daily environment, even if reluctantly welding, the plating was damaged and the metal frame will lost the original shape.

In fact, metal eyewear plating color fall off is the problem of plating issue, it has nothing to do with metal eyewear. Usually the metal eyewear is required to be plated finished. Here we introduce several plating process for metal eyewear and their advantages and disadvantages.

Electrophoresis plating, commonly known as “water-plating”, it refers of coating mirror surface on metal eyewear by electrolytic method, more commonly used in normal alloy metal eyewear. To take example, stainless metal eyewear, nickel silver metal eyewear etc..

Advantages: low cost, and rich colors
Disadvantages: Very low coating adhesion, gold, silver, gun generally available for about a year; other colors generally can occur color fall off in 3-6 months.
Most Chinese eyewear supplier applies water-plating method coating metal eyewear.

Heavy gold electroplate–divided into “multi-layer texture coating method” and “the multilayer plating method” of two kinds. These two kinds of galvanization technological requirement is a natural metal color, thus the frame color is a single adopting of such processing, basically gold, silver major color.

The feature is coated with a thick 3.5UM gold or silver, generally available for about many years, no skin irritation and discomfort complaints.

IP vacuum ion plating: heat frame surface to form negative ions, free in a vacuum furnace, combined with the pigment particles through current electrodes to the lead adsorption on the surface of frame plating layer is formed.
Advantage: Eco-friendly, strong electroplated coatings adhesion, generally available for about many years without color falling off.

Weaknesses: color is gloomy, plating is not bright.

Multi-coated divided into spraying and paint two types.
A, spraying process: used for many students metal eyewear outer coating and covering.
Advantages: rich colors, bright
Disadvantage: prone to falling off and fading.

B, baking varnish technology: Used for fashion frames;
Advantages: coating thick, colorful and bright
Disadvantages: easy to scratch, color fall off.

There are various metal eyewear plating method, quality plating refers to electroplating equipment, materials, technology and other related factors, compared to other plating method, vacuum ion plating process is more complex, technical requirements for equipment are higher, so it is not easy to color falling off, the plating cost more expensive.

Usually, metal eyewear material ranges are nickel silver, stainless steel, titanium etc… These materials processed through precision processing, e-plated with gold, silver, or popular painting colors finish. Metal eyewear is sturdy and durable; it has smooth surface and good appearance, light weight. Following is a brief introduction about our metal eyewear producing process:

For buffalo horn eyewear wearers, the most difficult problem is probably the buffalo horn eyewear out of shape.

It is a troublesome problem for the wearers, it will not only affect the users comfortable wearing, but also cause wearers feel fatigue, and headaches. If users wear such frame, in some cases, even endanger to the health of the wearers eyes.

Why buffalo horn eyewear out of shape?
Formerly, buffalo horn is a purely natural products and horn original texture and shape is curved, so horn raw materials have features of memory functions.

From our industry experience, other buffalo horn eyewear suppliers products is easily out of shape, some suppliers products won’t out of shape. How come it is?

Since a piece of horn material width is 170mmx60mm, during produce buffalo horn arms. In order to save horn material. Other buffalo horn eyewear suppliers engrave straight arms. In this method, they are able to cut out 2 pairs of arms, thus saving some production cost and make more profits.

However, this method was likely to cause products out of shape. Because these straight buffalo horn arms need bending procedure, for a few time, horn original texture and shape must bounce back into the original straight, eventually leading to the wearer’s buffalo horn eyewear out of shape.

In order to prevent buffalo horn eyewear out of shape because of memory functions, during engrave buffalo horn arms, our factory totally follows horn original texture and shapes. In this method, buffalo horn arm is a naturally curvature. No need bend-shape by hand in later procedures. These natural bending arms are not easy out of shape compared with straight arms. It is also not easily out of shape in wearer’s hand.

Actually, following horn original texture and shapes spends more horn material. If arms width relative big. Base on measurement 170mmx60mm horn raw material. It can only produce 1 pair of arms. For straight arms, it can produce 2 pair of arms. Our costs are increased by one half.

As a professional buffalo horn eyewear supplier, in order to peruse a high end quality buffalo horn eyewear product. We guarantee that all our buffalo horn arms produced by follow horn original texture and shapes.

How to shape by hand if your buffalo horn eyewear don’t have good shapes?

Buffalo horn is a purely natural products and horn original texture and shape is curved, so Horn materials have certain memory functions. What can we do if the buffalo horn eyewear don’t have good shapes caused by the horn material memory function?

If wearer or buyer choose to return it to the buffalo horn eyewear factory maintenance, can be a waste for a long time, and even take 1 month or more. And also during transport and custom clearance may be in troubles.

As a professional buffalo horn eyewear supplier, we would like to teach you following method to shape your buffalo horn eyewear by hand.
Using the HOT AIR GUN, if there is no HOT AIR GUN, also can use household electric hair dryers and transferred to the hottest grade. Blowing buffalo horn eyewear deformed front or arms over 10-20 seconds until horns soften, and then maintain good shape by hand. After maintain a good shape, then leave the buffalo horn eyewear cool in natural, never soak buffalo horn eyewear into water to cool it, it will make buffalo horn peeling or blistering.

When need maintenance buffalo horn eyewear by using horn cream to avoid it bursting?

From our experience, when the humidity of the air is around or greater than≥80%, buffalo horn eyewear is not easy to break or crack. When the humidity of the air is less than≤20%, buffalo horn eyewear will have a risk of bursting and crack.

So generally no need to use horn cream in summer, in the winter and spring, due to the drying air humidity, it had better use horn cream to maintenance buffalo horn eyewear.

1. Please don’t soak water, or use hot water washing, it has risks to loose shape and become mildewed. After washing by water, please remember wipe with a soft cloth immediately.

2. Please don’t put your buffalo horn eyewear on bed or next to bed to avoid be damaged when sleep. We recommended that take off buffalo horn eyewear into eyewear case or drawer.

3. Please don’t put your buffalo horn eyewear on sofa or car seat to avoid the risk of being accidentally breakage.

4. Please don’t fall, press buffalo horn eyewear due to avoid it broken.

5. Maintenance horn by using lanolin cream or some hand cream to avoid it brittle.

Firstly, let us learn what is the difference between materials and features of buffalo horn?

Natural white horn: white horn is glittering and translucent as jade, often with natural white and yellow natural textures. Is the best among buffalo horn eyewear, due to the scarcity of material resources, the prices remain high, and used for making high-end luxury buffalo horn eyewear.
According to experts, animal albino formed primarily by gene mutation. Such as white Tigers, White Lions, white Bull ….These are very rare and precious, and the White Buffalo is one of the most precious. A lot of people in the world treat White Buffalo as sacred animals.

Natural Blonde buffalo horn: Blonde buffalo horn is translucent brown, feels and touches comfortable, warm and humid color, which comes from high altitude area in India, with dry textures, there are relatively plenty of raw materials. But since import customs duties and shipping cost etc, Blonde buffalo horn eyewear price are relatively high.

Natural yellow horn: yellow horn is translucent yellow, with noise colors, with dry textures, there are relatively plenty of raw materials, and the price is relatively lower.

Natural black horn: Black buffalo horn from the South of Asian, heavy and thick, jet black color, Black horn is basically buffalo horn eyewear materials, as relatively plenty of raw material, the price is relatively cheaper than white and blonde buffalo horn eyewear.

Lastly, let us learn how is the difference of buffalo horn eyewear man craftwork, buffalo horn eyewear man craftwork distinguished mainly from raw materials, workmanship, gloss and precision difference. In General, low-quality Buffalo Horn eyewear craftwork roughly, touches and feels worse, low gloss, and some cracked inside the horn, or prone to breakage, low-quality of buffalo horn eyewear can’t last for many years. A perfect buffalo horn eyewear hand polishing much better than poor quality buffalo horn eyewear, excellent in workmanship and takes long time, a perfect buffalo horn eyewear cost is much higher, it is strong and robust which can last for many years for wearers.
