Project Background
This client is an Argentina-based resistance-welding machinery manufacturer, specializing in spot-welding electrode accessories.
Before cooperation, they faced 3 key procurement pain points:
Sourced copper parts & steel materials from 4 vendors, wasting 10+ hours weekly on communication.
Scattered shipments led to extra freight/clearance fees and long lead times.
Messy material certificates increased their incoming inspection workload.
They needed a one-stop supplier for all metal components and unified certification.
Customer Requirements
As a spot-welding machinery manufacturer, the client required:
Precision CuCrZr copper electrode parts (drawing-based);
H13/42CrMo/4340 steel bars & forgings;
Unified material certificates & consolidated shipment.

Production & Quality Inspection
CuCrZr Copper Machined Parts
The CuCrZr copper machined parts were manufactured according to the customer's drawings using precision CNC machining. Before shipment, each part underwent dimensional inspection to verify critical dimensions, hole positions and overall machining accuracy. Material certificates were also provided to confirm the chemical composition and traceability of the supplied CuCrZr alloy.
JBT4281-1999 C18150 Chromium Zirconium Copper Material Certificate (MTC)
Alloy Steel Round Bars
The H13 and 42CrMo round bars supplied for this project were inspected prior to delivery to ensure compliance with the specified material grades and dimensions. Each batch was accompanied by a material certificate, allowing the customer to verify heat numbers, chemical composition and mechanical properties before production.
Steel Forgings
The 42CrMo and 4340 forged components were manufactured to the required dimensions and inspected before shipment. Material certificates and dimensional inspection records were prepared for each forging to ensure conformity with the customer's project requirements and provide complete quality documentation.
