PROCESS

Process of Making Insulated Glass Units

Insulated glass production involves machines like washing units, spacer conveyors, and pressing units. The process entails bending a hollow aluminum spacer bar to shape, filling it with desiccant, and sealing it with primary sealant (butyl). Two glass panes are then pressed together with the spacer bar, and a secondary sealant (polysulfide or silicone) is applied to complete the unit.

1. Spacer Preparation
  • Hollow aluminum spacer bars are cut to the required length.
  • The spacer bars are bent to the desired shape using a bending machine.
  • The spacer bars are cleaned and prepared for the next step.

2. Desiccant Filling
  • Desiccant material (silica gel or zeolite) is inserted into the spacer bar.
  • The desiccant absorbs moisture from the air trapped between the glass panes, preventing condensation and fogging.

3. Primary Sealing
  • Butyl sealant is applied to the spacer bar's sides and holes.
  • The primary sealant provides an initial seal and helps to bond the spacer bar to the glass panes.

4. Glass Assembly
  • Two glass panes are positioned on either side of the spacer bar.
  • The glass panes are aligned and spaced evenly apart by the spacer bar.

5. Pressing
  • The glass panes are pressed together using an automatic presser.
  • The presser applies even pressure to ensure a tight seal and prevent air leaks.

6. Secondary Sealing
  • Polysulfide or silicone sealant is applied to the unit's sides.
  • The secondary sealant provides an additional layer of protection against moisture and air leaks.
  • The sealant is cured according to the manufacturer's instructions.

7. Final Inspection
  • The completed IGU is inspected for quality and airtightness.
  • The unit is checked for any defects, such as sealant imperfections or glass damage.
  • The IGU is then packaged and shipped to customers.

These steps ensure that the insulated glass unit is manufactured to high standards, providing excellent thermal performance, durability, and energy efficiency.
