Brief: Watch the demo to catch practical tips and quick performance insights. This video showcases the manual EI lamination stacking machine in action, demonstrating how its hand-cranked design efficiently inserts EI-type silicon steel sheets into coil bobbins for transformer core assembly. You'll see the precision stacking process, learn about its multi-specification compatibility, and observe how it improves production efficiency without requiring external power.
Related Product Features:
  • Hand-cranked operation requires no external power or air source for flexible workshop placement.
  • Mechanical positioning ensures ±0.02mm accuracy for neat stacking and uniform air gaps.
  • Achieves up to 250 stacks per minute with smooth mechanical transmission and comfortable cranking.
  • Compatible with EI series cores from EI14 to EI35 with interchangeable molds for quick model switching.
  • Compact steel construction with powder coating provides durability and long-term stability.
  • Reduces core looseness and eccentricity issues to improve product consistency and reduce defects.
  • Ideal for multi-variety, small-batch production of transformers and inductor coils.
  • Quick setup with minimal training required, enabling single operator management of multiple machines.
FAQs:
  • What types of transformer cores is this manual stacking machine compatible with?
    The machine is compatible with EI series cores including EI14, EI16, EI19, EI22, EI25, EI30, and EI35. Custom specification molds are also available for other core types.
  • Does this machine require any external power source to operate?
    No, this is a completely manual machine that operates via hand-cranking. It requires no external power or air source, making it ideal for workshops without specialized power modifications.
  • What are the main benefits of using this manual stacking machine compared to manual assembly?
    The machine provides precise positioning with ±0.02mm accuracy, reduces labor intensity and operator fatigue, improves insertion efficiency up to 250 stacks per minute, ensures neat stacking with uniform air gaps, and significantly reduces core looseness and defect rates.
  • How quickly can production models be switched on this machine?
    The machine features quick mold replacement capabilities, allowing for fast switching between different EI core and bobbin sizes. This makes it excellent for multi-variety, small-batch production and R&D sampling operations.
