Description
Manual EI Lamination Stacking Machine
Designed to improve productivity and accuracy in electrical motor core assembly processes, this hand-cranked laminator streamlines the insertion of EI-type silicon steel sheets into coil bobbins.
Equipment Overview
The Hand-Cranked EI Laminator is a manually operated device that efficiently inserts EI-type silicon steel sheets into coil bobbins for mass production of transformers and inductors. Mechanical positioning and alignment structures ensure product quality while reducing labor intensity and improving insertion efficiency.
Application Scope
Suitable Products
  • Power frequency transformers
  • Small power transformers
  • Inductor coils
Compatible Core Types
EI series cores including EI14, EI16, EI19, EI22, EI25, EI30, EI35 (custom specification molds available)
Key Features
Compact & User-Friendly Design
  • Hand-cranked operation requires no power or air source
  • Minimal space requirements for workshop, laboratory, or repair bench use
  • Quick setup with minimal training required
Precision Stacking Performance
  • Positioning fixtures and guiding structures ensure neat stacking and uniform air gaps
  • Reduces core looseness and eccentricity issues
  • Significantly improves product consistency and reduces defect rates
Efficient Operation
  • Smooth mechanical transmission with comfortable hand-cranking
  • Single crank stacks multiple silicon steel sheets efficiently
  • Ideal for medium and small-scale production requirements
Multi-Specification Compatibility
  • Adaptable to different EI core and bobbin sizes with interchangeable molds
  • Quick mold replacement for multi-variety, small-batch production
Durable Construction
  • High-quality steel construction with precision machined components
  • Simple mechanical design ensures low failure rate and easy maintenance
  • Excellent long-term stability with minimal upkeep requirements
