Product 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
