SM-J19 linear type glass socket and cone joint forming machine. Multi-station PLC-controlled production of standard and custom ground glass joint connections for laboratory glassware assembly.
The SM-J19 Linear Type Socket and Cone Machine is a specialised glass forming machine for the production of standard ground glass joint connections — the interchangeable socket (female) and cone (male) joints used to connect laboratory glassware components. These precision ground joints are a fundamental component of modular laboratory glassware assemblies worldwide.
The machine uses a linear multi-station configuration to form the tapered socket and cone profiles on glass tube ends. Each station applies controlled flame-heating and forming pressure to create the accurate taper angle and surface finish required for an airtight glass-to-glass seal — critical in laboratory distillation, synthesis, and gas handling applications.
Sea Melody has supplied laboratory glassware joint forming machines to manufacturers in Europe, Asia, and the Middle East, and the SM-J19 is designed to meet the precise dimensional requirements of international laboratory glassware standards.
