Moroccan Mining Group Completes Tuoxing Drill Rig Factory Inspection: Technical Strength Gains International Client Recognition

In mid-March 2026, a technical delegation from a major Moroccan mining group completed a three-day factory inspection at Tuoxing Heavy Industry's drill rig manufacturing facility. The visit aimed to evaluate Tuoxing's technical capabilities and manufacturing standards as part of the supplier selection process for an upcoming deep mining project.

Background: From Document Review to On-Site Verification
The Moroccan client has historically sourced drill rigs from European brands and approached the prospect of Chinese manufacturing with caution. During the preliminary technical document review phase, Tuoxing submitted product drawings, material test reports, and quality control system documentation, all of which passed the client's initial screening. This on-site inspection represented the final verification step before supplier qualification.

On-Site Assessment: Transparent Presentation of Full Manufacturing Process
During the inspection, the Moroccan technical team conducted a systematic review of Tuoxing's entire drill rig production process, including raw material inspection, structural welding, heat treatment, precision machining, and final assembly. Key evaluation points included:

Welding Quality Control: The client team randomly selected in-process weld seams for on-site review of ultrasonic testing reports. All sampled points met ISO 5817 Class B standards.

Heat Treatment Process Verification: The delegation witnessed the complete quenching and tempering process for critical structural components. Furnace temperature curve records matched actual heat treatment parameters, satisfying stringent mechanical property requirements for high-strength steel.

Full Load Testing: A drill rig underwent four hours of continuous operation at 110% rated load under client supervision. Hydraulic system temperature rise, vibration levels, and noise metrics all exceeded design specifications.

Technical Exchange: Focus on Mine-Site Operating Conditions
During technical discussions, both parties engaged in in-depth dialogue regarding the hard rock geology and high-temperature operating environments characteristic of Moroccan mines. Tuoxing engineers demonstrated drill rig parameter optimization solutions based on rock sample data from the client's mine, including thrust adjustment, rotation speed matching, and tool selection recommendations—demonstrating a thorough understanding of site-specific operating conditions.

Conclusion: Strength Earns Trust
Prior to departure, the Moroccan delegation issued a written evaluation formally confirming that Tuoxing's drill rig facility meets their supplier qualification standards. The evaluation noted that Tuoxing's manufacturing precision, quality control systems, and process stability have reached international levels, establishing the technical foundation for strategic supplier status.

Both parties subsequently signed a letter of intent for two customized drill rigs, with delivery scheduled for Q3 2026. The Moroccan client also extended an invitation for Tuoxing's technical team to conduct on-site operating condition research at their mine later this year, laying groundwork for future volume procurement.

This successful inspection marks Tuoxing's official entry into the North African premium mining market's qualified supplier list, reaffirming that transparent manufacturing processes and proven technical strength remain the only passports to international client trust.
