Halogen Lamp Automatic Production Line
sealing process
Schott H4 automatic production equipment
Halogen lamp filament material is ready for production
step 1
Glass shell is ready for production
step 2
The halogen lamp filament is assembled in a glass shell and then subjected to a sealing process
STEP 3
Stress relief (to eliminate the tensile stress generated on the glass surface after the clamping process, in order to cool down and adapt to changes in environmental temperature)
STEP 4
The sealing process has ended
STEP 5
exhaust process
Schott H4 automatic production equipment
- STEP1: The sealed bulb will go to next process- exhausting
- STEP2: Fill in hydrogen gas (to ensure cleanliness inside the light bulb)
- STEP3: Fill with halogen gas (fill with 10 atm halogen gas with a purity of 100% to prolong the lifetime of the light bulb)
- STEP4: Liquid nitrogen cooling (by soaking in liquid nitrogen, higher pressure halogen gas can be injected into the light bulb)
- STEP5: The gas-filled sealing semi-finished product is sealed by fire to make a bulb that can be light up
annealing process
Schott H4 automatic production plant
- STEP1: Start of annealing process
- STEP2: Annealing (eliminate the stress on the surface of the bulb to prevent the bulb from bursting)
- STEP3: Annealing process completed
filament production process
Quartz H7 Korea automatic production equipment
Filament forming
step 1
Filament shaping
step 2
Combine the quartz rod with the filament
STEP 3
Production Filament process completion
STEP 4
wick production process
Quartz H7 Korea automatic production line
- STEP1: Filament is ready for production
- STEP2: The filament is getting ready
- STEP3: Filament welding
- STEP4: Welding molybdenum sheet
- STEP5: The wicking process is completed
bubble shell production process
Quartz H7 Korea automatic production
- STEP1: Quartz glass tube forming
- STEP2: Glass tube is ready for production
- STEP3: Exhaust pipe is ready for production
- STEP4: The formed glass tube and the exhaust pipe are joined together by fire
- STEP5: Bubble shell production is completed
capsule clamping process
Quartz H7 Korea automatic production
- STEP1: Wick is ready for production
- STEP2: Bubble shell is ready for production
- STEP3: Put the wick into the bubble shell and seal it with fire
- STEP4: Bubble shell clamping process is completed
automatic exhaust process
Quartz Korea line H7 automatic exhaust process
- STEP1: Bubble shell is ready for production
- STEP2: Soak the surface of the shell with fire and fill it with hydrogen to light it (keep the inside of the bulb clean)
- STEP3: Fill with halogen gas, make the lamp brightness better, longer lifetime
- STEP4: Liquid nitrogen is used to cool the surface of the bulb, allowing it to be filled with more halogen gas
- STEP5: Seal with heat to make capsule
- STEP6: The capsule is finished
Assembly process
quartz H7 Korean production line
- STEP1: Capsule is ready for production
- STEP2: Automatic assembly buckle cap
- STEP3: Auto focusing, welded buckle cap
- STEP4: Automatic assembly of lamp holder
- STEP5: Automatic argon arc welding
- STEP6: The argon arc welded bulb is ready for the next step
- STEP7: Automatic coating
- STEP8: Dry the coating
- STEP9: Automatic lighting detection (screening out defective electrical parameters)
- STEP10: Halogen bulbs production completed
