Production Process
Source of Raw Materials:
CNC-Glass Cutting Process
The Process formally begins after the Sales Order and Optimization disc containing detailed instructions are released by the Estimation/ Marketing Department to the Production Department.
Upon receipt of the Sales Order and Optimization Disc, the Production Department delegates the Job Order to a particular Section.
With the Overhead Crane, The glass is loaded on the CNC cutting line table which then freely and slowly pushes the glass to the Lisec Cutting Machine for automatic cutting of the glass.
The Operator sets the mode of operation on the CNC Cutting Machine either manually or automatically. The operator retrieves and optimizes the program according to the sizes required considering minimal glass wastage. Once cutting is done, the glass is transferred to the breaking table for the breakout operation using the pneumatic push
Glass Tempering Process
From Cutting, the glass is transferred to the Arising/Polishing Section where sharp edges are arised. The glass is washed in the Washing Ma- chine and then loaded in
the Loading Station of the Tempering Machine. The furnace is heated at 700C with appropriate timing based on the type and thickness of the glass. The glass then proceeds in the Furnace for Tempering.
Glass Insulation Process
After the quality has been checked and approved, the aluminium spacer is assembled onto the unit. The aluminium spacer is placed in between two glasses and the unit passes through the pressing process.
To seal the double glass, Tremco Silicon 562 or Polyurethane or equivalent quality is carefully applied in its four sides by the LISEC Robotic Sealer machine.
The insulated glasses can also be sealed with silicon or polyurethane back-up pumps. Bur-IG is either processed with aluminium spacer, modified shuco spacer of shuco aluminium spacer according to the requirement of the client. The glass is stored for eight hours for curing or drying prior to delivery
Flat Lamination Process
If the glass requires lamination process, it is loaded to the Loading station and is transferred to the Washing Machine for Cleaning using treated water from Reverse Osmosis (R.O.) Plant.
Once the glass has been washed, using the Over head Crane with Automatic Lifters the first glass is lifted thereafter, the PVB is au- tomatically applied to the surface of the glass, after which the second glass is lifted glass and placed for accurate pairing applying PVB interlayer in between.
PVB film is cut and trimmed according to the size of the glass and the unit is transferred to the heating Furnace.
The glass batches of pre-laminated glass are fed / placed into the Autoclave cycle for final de-airing process. Glass processing in Auto Clave is a five hour – cycle for pressurized heating, cooling and re-pressurizing process.
Glass Insulation Glass Ceramic Fritting Process is as follows:
Packing and Delivery
Each glass is ensured to have no damage or scratches and has passed Quality Control checking before sending to Packing Division.
The glasses are covered with plastics and placed in wooden cases. These cases are finally sealed and tied with steel belt straps and are made ready for Delivery.
Delivery is done through BGF vehicles that have been specially modified for carrying glasses
