Eckold MVZ Series (Mobile Verschluss Zange — Mobile Closing/Clinching Pliers) is a specialized series of portable hydraulic pliers designed for the Seamclosing technology. Seam closing is a mechanical, non-impact joining method where the edges of two or more metal sheets are folded (seamed/hemmed) around each other under pressure. This technology ensures an ideal fit, hermetic sealing, and strength of the joint, and is a standard, particularly in the manufacturing of external car body panels (doors, hoods, boot lids, fenders). MVZ systems are a compact and economical alternative to stationary hemming presses, ideal for prototyping, small-series production, and repair work.

Features and Advantages

Feature	Description
Technology	Seamclosing (Seaming/Hemming) — Mechanical forming of the edges of metal sheets around a fixed element.
Field of Application	Primarily the automotive industry (joining of mounted body panels) and the repair of classic/vintage cars.
Mobility	Lightweight, hand-held hydraulic pliers that can be moved along large body components.
Hydraulic Drive	Hydraulic power ensures stable and high joining force with minimal noise level and high seam quality.
Configuration	Various models available (MVZ 11, MVZ 15, MVZ 17) with different working head configurations (e.g., $90^\circ$ angle or straight) and reach for access to hard-to-reach areas.
Precise Assembly	The joint is ideal, tight, and form-fitting, without the use of heat, which prevents the deformation of thin metal.
Insert System	Uses specialized exchangeable hemming inserts (Falzeinsätze), selected according to the specific seam profile and material thickness.

System Components

A complete Eckold MVZ seam closing system consists of three key components:

MVZ Mobile Pliers (Working Head): The actual operator-held tool that applies hydraulic force.
Hydraulic Power Unit (e.g., HA 510-F): External, compact unit that supplies the pliers with adjustable pressure.
Specialized Hemming Inserts (Working Tool): A set of exchangeable segments that form the joint. They are selected based on customer requirements and the hem configuration.
