The bridge is located in the center of the frames, connecting the two rims. It rests above the nose and bears most of the weight of the glasses.
Some frames have a low bridge fit, which means they’re crafted for people with low nose bridges (level with or below the pupils), wide faces, and/or high cheekbones. If you have one or more of these facial characteristics, you might find that low-bridge frames prevent the frames from sliding down your nose, pinching your nose, or resting on your cheeks.
In addition, some frames (including aviator styles) have a top bar that sits above the bridge, connecting the tops of the rims.
Endpiece
On the outer edge of each rim, you’ll find the end piece: a small part of the front frame that extends outward in order to connect the front frame to the hinges. Some glasses have elaborate, decorative end pieces.
Hinge
The hinges sit between the end pieces and the temples, and they play a pivotal role in the function of your glasses. Without them, you wouldn’t be able to close your glasses by folding the temples inward. Each hinge contains a screw.
Nose Pad
The nose pads are the round, plastic pieces under the bridge that rest on the nose. They help your glasses sit comfortably on your face.
Metal frames often include pad arms, which are adjustable pieces that attach the nose pads to the rims. They adjust to the wearer’s facial shape to provide a comfortable fit.
Lens
The lenses are what allow you to see clearly. They’re commonly made of clear plastic, high-index plastic, or polycarbonate, and a variety of styles and features are available, including bifocals, progressives, and Transitions®.
Rims
The rims give the glasses form and character and hold the lenses in place. They can be thick or thin, simple or elaborate, understated or eye-catching, and any color imaginable. Some glasses are rimless, which means they lack a frame front and have a minimalist, barely-there appeal. On rimless frames, the bridge and temples connect directly to the lenses.
Screw
Tiny screws, typically made of metal or plastic, are inserted into the hinge to connect the temples to the end pieces.
Temples
The temples are the arms on each side of the frame, extending from the front of the frame to behind your ears.
Temple Tip
Sometimes referred to as earpieces, the temple tips are located at the ends of the temples. They are the portion that rests behind the ears, providing extra comfort (especially on glasses with metal frames).
Customer Target Specifications
Regarding the product:
Around 14 cm of width and 14 cm of length on the "legs"
The frame around the glasses 4-5 cm
it should be easy to fit the glasses into the frame
the joints between the front part and the "legs" should be simple (do not know if it's possible to do it without adding any other piece or material there) and strong (uneasy to break)
Regarding the mould:
The mould should be produced with locally available low tech (welding, cutting) and materials (steel mainly)
Maximum length from the inlet of the mould to any edge 20 cm.
The lighter the mould, the better.
Clamping force: The moulds we have used up to date are composed of two or three layers that are clamped together with bolts and nuts (see examples below).
What is the nature of the plastic that is intended to be recycled and used for molding the glass frames ?(Hint: Specify the plastic identification code normally placed inside a triangle,see image below )This is needed for thermal analysis of the mold.
We mainly work with HDPE (#2)& PP(#5). A few times we use LDPE (#4)
