Overview

The SM-J57 Glass Sealing Machine is a PLC-controlled lathe-type double-station bottom sealing machine for forming glass bottle and jar bottoms as well as special profile bases. It is specifically designed for products with large diameter and low height, including decorative glass pieces, industrial glass containers, and scientific glassware.

The double-station lathe design provides stable rotation and consistent sealing quality across production runs. Adjustable flame intensity and rotation speed allow the machine to handle a wide range of glass types and thicknesses with minimal operator skill required.

Frequently Asked Questions

What types of glass products can the SM-J57 seal?

The machine is designed for large-diameter, low-height glass items including bottle and jar bottoms, decorative glass pieces, industrial containers, and special profile glass bases. It is not suited for narrow-necked or tall-profile glass products.

What is the advantage of the double-station design?

The two stations allow one piece to be loaded or unloaded while the other is being processed, significantly improving throughput compared to single-station machines without adding complexity or floor space.

Can the machine handle different glass thicknesses?

Yes — the adjustable flame intensity and rotation speed allow the SM-J57 to accommodate a range of glass thicknesses and compositions. Sea Melody recommends testing your specific glass type during commissioning to dial in optimal settings.

What is the typical 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 this machine be customised for non-standard glass profiles?

Yes — Sea Melody can engineer custom tooling and flame configurations for non-standard base profiles. 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.
