Overview

The SM-J76 Cylinder Base Welding Machine is designed for flame-welding flat or convex glass bases onto cylindrical glass bodies, producing sealed glass cylinders used in lighting components, scientific instruments, and decorative glass products. The machine uses a precisely controlled oxy-gas flame and rotating fixture to achieve a consistent, airtight weld between the cylinder body and base.

The SM-J76 is used where a flat-bottomed or profiled base must be permanently joined to an open-ended glass tube or cylinder with structural and optical clarity.

Key Features

  • Precise oxy-gas flame welding for clean, airtight cylinder-to-base joints
  • Rotating fixture ensures even heat distribution around the weld joint
  • Adjustable flame intensity for different glass types and wall thicknesses
  • Consistent weld quality with minimal distortion
  • Suitable for borosilicate glass and standard soda-lime glass
  • Compact design for workshop and production line use

Frequently Asked Questions

What types of glass joints can the SM-J76 weld?

The SM-J76 is designed for cylinder-to-base joints — welding a flat or convex glass disc onto the open end of a glass cylinder. It is not suited for tube-to-tube or angle joints, which require different equipment.

Is the weld airtight?

Yes — when properly executed, the oxy-gas flame weld produces an airtight, permanent joint with strength comparable to the parent glass. Weld quality depends on matching glass compositions and correct flame settings.

What glass types are compatible?

The machine is compatible with both borosilicate and soda-lime glass. When welding, the cylinder body and base must be the same glass type to avoid thermal stress cracking.

What is the lead time?

Standard lead time is 40 working days from order confirmation, as each machine is manufactured to order. For custom or modified machines, allow approximately 60 working days. Contact us for a specific timeline based on your requirements.

Can the machine be customised for non-standard cylinder sizes?

Yes — Sea Melody can adapt fixtures for different cylinder diameters. Visit our Custom Orders page to discuss your requirements.

What after-sales support is included?

Sea Melody provides 24/7 remote support with a 5-minute response time, online video commissioning, operation manuals, and spare parts supply. See our After-Sales Support page for full details.
