YANGLI YLK and J75G Series:
The Pulse of Electronics Manufacturing
Velocity Without Compromise. High-Speed Automation
In the world of high-speed electronics and electrical manufacturing, profit is found in the fractions of a second. Whether you are producing motor laminations for EVs or fins for industrial HVAC systems, your floor depends on the ability to maintain micron-level accuracy while cycling at over 1,000 strokes per minute.
As the authorized partner for YANGLI, GMT Engineers provides the high-frequency platforms that South India's tech hubs in Bangalore, Chennai, and Hyderabad demand. YANGLI's YLK and J75G series represent the peak of high-speed automation, engineered to eliminate the thermal drift and vibration that compromise quality in legacy machines.
The "Silent" Killer of High-Speed Dies
"Why do my dies fail faster at high speeds?"
In high-speed stamping, the primary enemy isn't the metal—it's Vibration and Heat.
The Vibration Problem
At 800+ SPM, even a microscopic frame oscillation becomes a hammer blow to your die pins. If the frame isn't dynamically balanced, the "bounce" leads to chipping and misalignment.
The Thermal Problem
As the crankshaft warms up, it physically grows. A 0.05 mm expansion in the crankshaft translates to a change in your shut-height, leading to inconsistently formed parts or "bottoming out" the die.
The GMT and YANGLI Solution:
Dynamic Balancing
Every J75G includes counterweights that move in perfect opposition to the slide, cancelling out 98% of machine vibration.
Active Oil Cooling
By circulating cooled oil through the main bearings, we maintain a constant thermal state, ensuring your shut-height remains stable from the first stroke to the last.
The Motor Core Specialist: YANGLI's J75G High-Speed Lamination
YANGLI's J75G Series is the definitive choice for high-speed stamping of stator and rotor laminations. For the burgeoning EV and appliance motor sectors, this series provides the rigidity required for ultra-thin silicon steel processing.
Dynamic Balancing Technology
To achieve speeds up to 1200 SPM, the J75G utilizes an advanced dynamic balancing system that neutralizes the massive inertial forces generated during high-speed operation. This ensures the machine remains stationary and silent, protecting your precision dies from premature wear.
Thermal Displacement Control
High-speed friction generates heat. The J75G is equipped with an integrated oil cooling and lubrication system that keeps the slide and crankshaft at a constant temperature, preventing the thermal expansion that leads to "shut-height drift."
Micro-Inch Adjustment
Features a high-resolution motorized slide adjustment that allows for extreme precision when setting up complex progressive dies.
HVAC Efficiency: YANGLI's YLK Series Coil Fin Presses
Specialized for the rapid production of Air Conditioning (AC) fins, YANGLI's YLK Series is a high-speed production engine designed for 24/7 HVAC fabrication.
Ultra-Wide Bed Design
The YLK is engineered with a wide bed to accommodate the long, multi-station progressive dies required for fin production, including louvering, flaring, and cutting.
Synchronized Feeding
Perfectly integrated with high-speed coil handling and vacuum stacking units, the YLK creates a "lights-out" manufacturing environment for high-volume coil production.
Physical Certainty in Every Fin
The high-rigidity frame ensures that even at maximum speeds, the louver heights and collar diameters remain identical, ensuring optimal thermal performance in the final AC unit.
The Future of Energy: Lithium Battery Production Lines
As India transitions to green energy, GMT Engineers is at the forefront of the Lithium-Ion Battery revolution. Our high-speed stamping platforms are now being deployed in specialized battery lines for:
Cell Can Stamping
High-speed production of cylindrical and prismatic battery casings.
Busbar Fabrication
Precision punching of copper and aluminum connectors with zero-marking requirements.
Current Collector Foils
Specialized high-frequency cutting of ultra-thin electrode foils where edge quality is critical.
Frequently Asked Questions
01What is the maximum speed (SPM) of the J75G series?
Depending on the stroke length and part geometry, the J75G can achieve stable production speeds of up to 1200 Strokes Per Minute (SPM).
02Do these machines come with a vacuum stacking system for laminations?
Yes. We provide completely integrated turnkey lines, including the high-speed press, decoiler, vacuum stacking units, and scrap conveyors specifically designed for the motor core industry.
03How do you ensure the machine doesn't "walk" or move at 1000+ SPM?
Aside from internal dynamic balancing, we utilize specialized anti-vibration mounts and, for our highest-speed models, recommend specific foundation engineering which our team helps design during the installation phase.
