How do you make gold-rimmed eyeglass frames look elegant when you wear them?


Glass design

The entire spectacle frame needs to be designed before going into production. 🤔 Instead of saying that glasses are an industrial product, they are actually more like custom handicrafts that are mass-produced. Since I was a child, I felt that the homogenization of glasses is not so serious, and I have never seen anyone wear them .Also, optical stores are also full of...

The first step in industrial design~ Designers first need to draw three kinds of glasses, and now they can go directly to 3D modeling, as well as the necessary accessories, such as glasses bridges, glasses legs, nose pads. , loops, etc. When designing, the requirements for the shape and dimensions of fittings are very high, otherwise this will affect the accuracy of the assembly of subsequent parts.

Points around

The official production of eyeglass frames starts with the large roll of metal wire in the picture below~

First, several sets of rollers twist the wire, extracting it, and directing it to make glasses rings.

The most interesting part of eyeglass ring making is completed by the automatic ring winding machine shown in the picture below. According to the shape of the processing drawing, it is wound and then cut. This may be the most automated step in the glasses factory~

If you want to make semi-framed glasses, just cut a half circle out of them~

Attach the lens ring

The lens must be inserted into the inner groove of the eyeglass ring, so a small fixing piece is used to connect the two ends of the lens ring.

First fix and clamp the locking block, then place the mirror ring on top, apply flux and heat the metal wire to weld them together (ah, that familiar welding)... This way of using the Welding method of pouring the joining of two metals with other metals with low melting temperature (solder) is called soldering~

After welding both ends, the mirror ring can be fixed~

Spectacle jumper

Then a miracle happened after great force...the punching machine bent the jumper of the glasses...

Align the lens ring and bridge of the nose in the mold and fix them tightly.

Follow the previous design and put them together~

Automatic welding

Of course, there is also an automatic welding machine~ I made a double speed in the picture below, it's the same, first fix the various parts in the position where they should be... and then fix it!

Close up: This sponge is the welding head of an automatic welding machine that can replace manual welding. The nose braces on both sides of the nose, as well as other accessories, are welded in the same way.

Production of legs for glasses

After finishing the frame part of the glasses on the nose, we need to make the legs of the glasses on the ears~ The first step is to prepare the raw materials, first cut the metal wire to the appropriate size.

It then passes through an extruder where the metal end is stamped into a die.

This is how one end of the bow is pressed vigorously into a small drum.

Then use a small punching machine to flatten and smooth out the slight bulge~ I can't find any close-up animation here, so let's just look at the static image to see... (I think you can)< /p>

After that, a loop can be welded onto the flat part of the mirror leg, which will later be connected to the glasses ring. The degree of relaxation of the legs of the glasses depends on the accuracy of the fit of this hinge~

Mounting screws

Now use the screws to connect the temples to the rim. The screw used for the connection is very small, about the size of a millet...

The picture below shows an enlarged screw, but here is a close-up~ A cute baby who often turns the screw to adjust the tightness must have a heart...

Lock the eyeglass leg hinges and use the machine to automatically tighten the screws and tighten them in seconds. The advantage of using machine automation nowadays is not only to save labor, but also that the given force can be well controlled, it will not be too tight if it is increased by one point, nor too weak if it is reduced by one point. . ...


Glasses frame after welding beforeshould go to the drum for grinding to remove burrs and round corners.

After that, workers should place the frame on a rotating grinding wheel and polish it carefully to make the frame more shiny.

Clear Coating

Once the glasses frames are polished, it's not over yet! It needs to be cleaned, soaked in acid to remove oil and impurities, and then electroplated to coat with an anti-oxidation film... This can no longer be approved, it is electroplating!

Curved temples

Finally, put a soft rubber sleeve on the end of the mirror leg, and then use the machine to make a full bend, metal eyeglass frame, and you're done~
