Technical DetailsNamibia's industrial growth is heavily anchored in challenging environments. From the world-class uranium deposits in the Namib Desert (such as the Husab and Rössing mines) to the intense offshore diamond recovery operations near Lüderitz and the deepwater shipping activities at Walvis Bay, the infrastructure demands materials that can survive extreme mechanical stress and corrosive attacks.
Traditional carbon steel components frequently fail under Namibia’s unique coastal conditions—characterized by dense, saline sea-fogs and high ambient temperatures. Consequently, engineering firms are increasingly specifying austenitic, duplex, and super-duplex stainless steels. Precision lost wax casting (silica sol process) provides the exact dimensional tolerances (ISO 8062 CT4-CT6 class) and surface finish required for complex pump impellers, desalination valve bodies, and wear-resistant mining gear.
As a leading global precision manufacturing partner, we bridge the gap between heavy-duty metallurgical science and localized engineering deployment, ensuring that every cast component delivered to Windhoek, Walvis Bay, or Oranjemund meets international ASTM, EN, and DIN standards.

Technical DetailsAt JUNLONG Machinery, our production process is designed to deliver reliable stainless steel components to global clients. The technical roadmap details every step, ensuring compliance with strict international testing specifications:
We execute strict chemistry control for grades including CF8 (304), CF8M (316), CF3 (304L), CF3M (316L), and various duplex stainless steels (such as 2205 and 2507). Prior to pouring, each melt is verified using an OES (Optical Emission Spectrometer) to guarantee chemical compliance, preventing the risk of intergranular corrosion once deployed in the field.
Using CAD/CAM engineering designs and CNC-machined aluminum tooling, we manufacture wax patterns with close dimensional tolerances. This ensures that the cast component aligns with your drawings, minimizing the need for extensive post-machining and reducing material waste.
To confirm the integrity of our castings, we offer optional NDT methods based on client requirements:
Our manufacturing floor features automated shell-building lines, constant-temperature drying rooms, and medium-frequency induction furnaces to ensure consistent casting quality.
Our stainless steel castings are deployed in critical components across multiple demanding global industries.
Wear-resistant discs, couplers, and gears optimized for sub-Saharan soil conditions.
Valves and connectors built to handle oil, gas, and corrosive chemical refining agents.
High-performance manifolds, turbochargers, and heavy engine brackets.
Forging Strong Mechanical Backbones, Conquering Extreme Conditions for heavy equipment like excavators, loaders, and cranes.
From initial design concepts to final product delivery, all key processes are completed in-house:
Customer Value: Eliminates communication costs, quality risks, and delays associated with multi-factory collaboration, enabling full-process quality traceability with a single point of responsibility.
JUNLONG Machinery operates under a strict, audited quality framework. The company has obtained ISO 9001, TS 16949, UL, and other quality management system certifications, ensuring process control over every production detail and continuously pursuing and improving product quality to achieve high customer satisfaction.
