Electrical upsetting machines and servo screw presses that form precise, defect-free bulbs and flanges from bar stock. The benchmark for engine valve production in India — with near-zero rejection rates proven across millions of parts per year.
ETA was among the first to understand that producing a perfect engine valve bulb is pure science, not operator art. The result: machines that deliver the correct bulb shape, consistently and without cracks.
IGBT-controlled heating with three-phase input, sinusoidal power, and optical pyrometer temperature sensing prevents over-heating and eliminates root cracks — the industry's most common cause of rejection.
Servo-controlled hydraulic anvil and upsetting units ensure the same bulb geometry on every cycle. All settings except jaw and anvil change can be made offline — zero production interruption.
Vertical configuration occupies significantly less floor space than horizontal competitors. For high-density valve lines, this is a decisive manufacturing advantage.
Auto-loading from bins, component transfer, and integrated robot handling available. The complete High-Speed Production Cell pairs two upsetters with a servo screw press and robot for one valve forging every 5 seconds.
Real-time upsetting load measurement via load cell. Process data logging and remote monitoring capability built in. Integrates with ETA's connected manufacturing platform.
Lubrication provided to all sliding parts. Robust hydraulic power pack design with proven long-term reliability. ETA's service team and spare parts available throughout the machine's life.
All machines are engineered-to-order. Configurations below represent the standard range — customised to your bar geometry, production volume and automation level.
Vertically configured machines for producing flanged bulbs from bar stock — the core of every engine valve manufacturing line. Single-head (20kVA) and twin-head models with auto loading and unloading. IGBT heating control ensures crack-free bulbs every cycle.
Servo-controlled positive-drive screw press for precision forging of valve heads. Pairs with upsetters in automated cells. CNC-controlled forming ensures consistent head geometry across millions of cycles without operator dependency.
Complete automated cell: two twin-head upsetters + servo screw press + component-handling robot. Synchronized for continuous production. Capable of one valve forging every 5 seconds — the fastest commercially available valve forging line.
