Product Description

Discription

Our components use precision machining, including:
-CNC turning (lathes) for cylindrical forms, threads, tight-tolerance rotational features.
-CNC milling for slots, holes, complex 3D geometries in custom parts.
Surface finishes:
-Natural metallic (showcasing material quality).
-Anodizing (common for aluminum) and Zinc plating for uniform color/texture—boosts corrosion resistance, hardness, and lifespan.
These machined parts serve global industries:
Automotive & aerospace: Connectors, fasteners, fluid system parts for reliable fuel, oil, coolant transmission.
Manufacturing & machinery: Key in precision mechanisms (CNC machines, robotics, production lines).

Quality Policy

1- Raw Material Control
Sourced from ISO 9001/14001 certified suppliers, with mandatory material certificates (e.g., mill test reports). Incoming checks include dimension verification (calipers, micrometers), surface defect detection (visual/ultrasonic tests), and composition analysis (spectrometers for critical materials). Unique batch IDs enable full traceability.
2- Pre-Machining Validation
Engineers validate CNC programs, tooling, and fixtures against 3D drawings pre-production to ensure precision and minimize setup errors.
3- In-Process Real-Time Checks
Hourly inspections of critical dimensions (via CMM for high precision), tool wear, and surface finish (against standards). Parameters and results are logged to address deviations quickly.
4- 100% Final Inspection
All parts undergo dimensional checks (CMM, optical comparators) to meet tight tolerances (±0.005mm max), functional tests (assembly trials, pressure/wear tests as needed), and surface inspections (for flaws using magnifiers and roughness testers).
5- Pre-Shipment Assurance
Random batch rechecks for consistency, anti-rust/shock-proof packaging (meeting transport standards), and comprehensive quality reports (inspection data, certificates) with each shipment.
