Learn MoreAs the global energy transition accelerates, the demand for highly efficient electrical conduction elements has hit unprecedented heights. Traditional rigid busbars, while offering low resistivity, lack the flexibility required to absorb mechanical stresses, structural alignment tolerances, and thermal movements. Modern power electronics applications, including electric vehicle (EV) battery packs, high-capacity switchgears, and utility-scale solar inverters, require advanced electrical pathways that provide both maximum ampacity and mechanical compliance.
A laminated copper strip flexible connection is engineered by stacking multiple thin electrolytic copper foils (typically ranging from 0.05 mm to 0.5 mm in thickness) and bonding the terminal contact areas under extreme heat and pressure. Using solid-phase molecular diffusion welding (press welding), the ends of these stacked sheets are fused into a solid, molecularly uniform block of copper without the addition of any foreign solders. This ensures that the weld interfaces exhibit identical electrical conductivity and mechanical properties to the raw parent metal, preventing hot spots and electrical failures under demanding dynamic loads.
Fusing copper laminate ends at the atomic level without foreign solders, maintaining 100% pure copper electrical performance and eliminating thermal fatigue failure points.
Designed to absorb constant vibrations in heavy transport and automotive powertrains, extending the structural lifecycle of fragile cell terminals and electronics.
Our automated cutting and CNC stamping capabilities allow custom bending, offsetting, and thickness modifications tailored for high-density space requirements.
The global marketplace for copper connections has fundamentally evolved from a raw commodity supply structure to a custom-engineered solutions model. With the rise of modular mega-factories and localized production hubs, industrial users are demanding supplier compliance with ISO 9001:2015 and ISO 14001:2015 standards, alongside proven traceabilities of raw materials. High-purity T1/T2 electrolytic copper remains the material of choice owing to its electrical conductivity rating of ≥100% IACS (International Annealed Copper Standard).

Find answers to key technical questions on materials, molecular welding, and performance criteria.
Molecular diffusion welding fuses stacked copper foils into a single solid mass via atomic-level bonding under extreme heat and pressure. It uses no brazing alloys or foreign chemical solders. This ensures the connection terminal retains 100% of the purity and conductivity of copper, without adding mechanical joint boundaries or increasing electrical contact resistance over time.
We use T1/T2 grade electrolytic copper with ≥99.9% purity levels. Lower grade copper with high levels of impurities significantly increases electrical resistivity. Under continuous load, this generates heat loss (I²R), driving up temperatures and accelerating terminal degradation. High-purity copper maintains optimal current capacity with minimal thermal loading.
Plating choice depends on operating conditions. Tin plating is the standard industrial option, offering cost-effective protection against surface oxidation. Silver plating is used for high-frequency or high-temperature environments, providing low contact resistance at joint interfaces. Nickel plating is chosen for environments with high acidity or chemical exposure.
We customize parameters including total connector length, lamination stack thickness, single-foil thickness (ranging from 0.05 mm to 0.5 mm), connection shape, surface plating, mounting-hole patterns, and insulation styles (PVC sleeve, silicone tape, or heat-shrink tubing).
Yes. Laminated copper flexible connections are designed to absorb physical vibrations and thermal expansion. Under thermal cycles, metals naturally expand and contract; rigid links transfer this stress directly to fragile ceramic insulators or terminals. The loose lamination stacks absorb these stresses within the connector, protecting the electrical terminals.
