Why this step belongs in the base scope
The junction box carries copper conductors, solder joints and polymer. The cable attached to it may be a metre or two of insulated copper. None of that belongs in a glass cullet stream, and once it has been shredded into one it cannot be taken back out economically.
The arithmetic is simple: this is a low-cost station that protects the value of the two largest streams in the plant. Plants that omit it usually discover the problem through a rejected container of cullet rather than through a failed machine.

What the station does
- 01
Receive the frameless laminate
The module arrives with the frame removed and the box still attached to the rear face.
- 02
Detach the box
The box is cut or prised away from the backsheet or rear glass without damaging the laminate underneath.
- 03
Coil the cable
Cable is separated and coiled into its own container — it is the largest single copper-bearing item on a module.
- 04
Collect separately
Boxes and cable go into a dedicated container, weighing each batch so the copper stream is accountable in the plant mass balance.
- 05
Release to glass handling
The laminate continues to glass separation with no metal-bearing attachments left on it.
03
Manual, semi-automatic or in-line
On lower-volume lines this is normally a manual station with a fixture and a dedicated container — the cost is low and the flexibility is genuinely useful, because junction box designs and cable lengths vary between module families.
On higher-volume lines the station is integrated into the transfer conveyor so the operator works at line height rather than lifting laminates onto a bench. Which version you need follows from your through-put and your labour model, and it is one of the more straightforward decisions in the whole line specification.

A note on handling
Electrical state before dismantling
Modules that have come off an operating array may still hold charge, and junction box and cable assemblies are the part of the module where that matters most. The electrical state of the incoming material, the isolation procedure and the PPE your operators need are matters for your own risk assessment and, where applicable, your regulator. We design the station's handling and guarding to the requirements you set, but we do not set them for you.
Adding a line to an existing dismantling hall?
Tell us the space and the through-put. We will show you where the box station fits and what it takes out of the streams you are already selling.
FAQ
Questions
Is junction box removal really necessary?
If you intend to sell glass cullet, yes. Copper and polymer from the box contaminate the glass stream, and because it happens before size reduction it is cheap to prevent and impossible to reverse afterwards. It is one of the few steps in the line that almost always pays for itself.
Is the junction box removed before or after the frame?
After the frame and before any glass handling. The frame is removed first because it carries the most immediate value and the most risk of damaging the glass; the box follows immediately, while the module is still a flat laminate that is easy to work on.
What is recovered from junction boxes?
Copper from the conductors and cable, solder-bearing joints and polymers from the housing. The mass is small compared with glass and aluminium, but the copper is a straightforward metal stream once it has been kept separate.
Can one operator run the station?
Yes, at most through-puts a single operator runs the box station. What changes between installations is the fixture, the working height and the container arrangement rather than the number of people.
