Brief: Watch a guided demonstration of the Manual EI Lamination Stacking Machine in action. This video shows how to neatly and quickly insert EI-type silicon steel sheets into coil bobbins for transformer and inductor production. You'll see the hand-cranked operation, mechanical guidance system, and how to switch between different core specifications. Learn how this equipment improves insertion efficiency, ensures product quality, and reduces labor intensity in electrical motor core assembly processes.
Related Product Features:
  • Compact hand-cranked design requires no power or air source, making it suitable for workshops and laboratories.
  • Mechanical positioning fixtures ensure neat stacking of EI sheets with uniform air gaps for improved electrical performance.
  • Effort-saving cranking mechanism allows comfortable operation with efficiency far higher than manual insertion.
  • Multi-specification compatibility through easy mold replacement for different EI core sizes from EI14 to EI35.
  • Durable construction with steel frame and precision machined parts ensures long service life and low maintenance.
  • Significantly reduces core looseness and eccentricity issues compared to pure manual stacking methods.
  • Ideal for multi-variety small-batch production with quick model switching capabilities.
  • Low investment cost solution for small and medium enterprises needing improved productivity without full automation.
FAQs:
  • What types of cores is this manual laminator compatible with?
    The machine is compatible with EI series cores including EI14, EI16, EI19, EI22, EI25, EI30, EI35, and others. Different specification molds can be configured according to your specific requirements for multi-variety production.
  • Does this equipment require any external power source?
    No, this is a completely manual hand-cranked machine that requires no electrical power or air source. This makes it highly flexible for various workshop environments and eliminates the need for additional infrastructure investments.
  • How does this machine improve product quality compared to manual insertion?
    The machine features positioning fixtures and guiding structures that ensure neat stacking of EI sheets with uniform air gaps. This significantly reduces issues like core looseness, eccentricity, and improves transformer electrical performance and stability while lowering defect rates.
  • Is this suitable for small batch production and R&D applications?
    Yes, the manual laminator is ideal for multi-variety small-batch production and R&D sampling. The simple mold replacement system allows quick switching between different core specifications, providing excellent flexibility for changing order requirements and experimental setups.
