ALCAVIL

The Origin

ALCAVIL was founded in 1998 in Monterrey, when a group of field engineers identified a systemic failure in the automotive supply chain: suppliers delivered electrodes with metallurgical inconsistency and poor machining tolerances, causing unplanned line stoppages.

What We Do

We are not middlemen. We are a machine shop specialized in resistance welding consumables, understanding the needs, workflows and standards this process demands. We integrate the value chain by directly importing certified raw materials to guarantee traceability from foundry to your assembly line.

Quality

Every electrode we manufacture meets RWMA/AWS J1.3 specifications. We work with Class 1, 2 and 3 alloys to satisfy the requirements of OEM, Tier 1 and Tier 2 in automotive, aerospace and appliance sectors.

Maintenance

Cooling Water Temperature

60% of premature electrode wear is due to poor cooling. A chiller with water at >25°C causes thermal softening even in C18150. Optimal ranges: 18-22°C, minimum flow 6 L/min. Learn how to diagnose cooling problems.
