Designed for the automotive body‑in‑white welding sector, the EGT081 is a precision‑machined aluminium connector that forms the backbone of flexible gripper and clamping systems. It is engineered to meet the stringent requirements of leading OEMs such as VW, Audi, Benz, BMW, and major Chinese NEV manufacturers, making it a trusted component in high‑volume production lines.

Product Configuration
Each EGT081 set includes all necessary fastening and locating elements for a complete 80‑mm‑tube cross‑connection:
– 12 double‑disc spring washers (DNL 8F)
– 12 socket head cap screws (DIN 912 – M8x30)
– 12 M8 rivet nuts (EGT 214)
– 2 locating pins (EGT 212)
– 1 cross connector body for 80×80 tubes (A356.2 casting)
All supplied parts are ready for immediate assembly, with the connector body machined from a high‑quality aluminium casting.

Material & Weight
The connector is cast from A356.2 aluminium alloy, a material renowned for its excellent strength‑to‑weight ratio, corrosion resistance, and non‑magnetic properties. This lightweight characteristic is particularly advantageous in aluminium spot‑welding applications, where magnetic interference must be avoided, and it offers a cost‑effective alternative to expensive non‑magnetic tool steels. The finished unit weighs only 1.7 kg, contributing to lower robot inertia and reduced energy consumption.

Critical Dimensional Tolerances
To ensure flawless assembly and consistent performance in automated cells, the EGT081 is machined to exceptionally tight tolerances:
– Perpendicularity: ±0.02 mm
– Hole spacing: ±0.02 mm
These values guarantee that every connector mates perfectly with standard 80‑mm tubes and mounting interfaces, eliminating play and securing repeatable positioning over millions of cycles.
—
Advanced Machining & Interchangeability
All critical faces are processed on 4‑axis CNC machining centres in a single setup. This approach allows multiple surfaces to be machined simultaneously, drastically reducing production time while ensuring superior dimensional stability. More importantly, the process guarantees full interchangeability – any left‑half housing can be paired with any right‑half housing without performance degradation. Many competitors cannot achieve this level of consistency, often resulting in mismatched pairs that compromise fixture accuracy and service life.
—
Surface Finish & Deburring
Every connector receives a bright, glossy appearance as standard. Mechanical deburring is applied throughout, delivering clean edges, uniform aesthetics, and repeatable quality. This not only enhances visual appeal but also prevents sharp burrs that could damage cables or injure operators during handling. (We can provide before‑after comparison photos of manual versus mechanical deburring upon request.)
—
Quality Documentation & Inspection
Each batch is accompanied by comprehensive inspection reports, including dimensional measurements, material certificates, and surface finish records. Our quality system follows rigorous automotive‑grade protocols, ensuring full traceability and compliance with customer specifications. We are prepared to supply PPAP packages and other documentation as required.
—
System Compatibility & Integration
The EGT081 is designed for seamless integration into existing Euro‑standard gripper systems:
– Connects directly to Euro‑standard 50/63 clamping cylinders
– Mounting faces are compatible with ABB‑style aluminium supports and other popular standard brackets
– Pre‑drilled locating holes are provided for L‑bracket installation, offering flexible mounting options
This modularity simplifies tooling design, reduces engineering effort, and accelerates changeover times on the shop floor.
—
Customisation & Turnkey Capabilities
Beyond standard offerings, we provide customised hole patterns for connecting supports, tailored to specific fixture layouts. Furthermore, we are proud to offer turnkey solutions for complete gripper assembly and inspection – fully compliant with BMW, Benz, and other OEM standards. From design and machining to assembly and final testing, we deliver ready‑to‑run systems that meet the highest quality benchmarks.
—
Market Advantage & Technical Heritage
With a technical foundation rooted in German engineering and continuous absorption of European manufacturing best practices, our production facility combines decades of experience with state‑of‑the‑art equipment. The EGT081 embodies this expertise, providing automotive welding lines with a reliable, lightweight, and non‑magnetic connector that reduces both tooling weight and overall system cost. Our commitment to interchangeability, tight tolerances, and responsive customisation gives our customers a competitive edge – higher uptime, better weld quality, and lower total cost of ownership.
