Technical SpecsGitarama, historically recognized as one of Rwanda’s primary economic epicenters and now incorporated under the Muhanga District, is rapidly transforming into a crucial logistical corridor and secondary city hub. Located at the intersection of the primary highways linking Kigali to the western region and neighboring nations, Gitarama hosts burgeoning local operations in food processing, brick manufacture, industrial assembly, and artisanal mineral refining (particularly coltan and cassiterite mining sites in the wider Southern Province).
However, the local manufacturing ecosystem faces structural limitations regarding high-precision subtractive machining. Local tool shops rarely host 4-axis or 5-axis vertical machining centers or automated coordinate measuring machines (CMM) capable of maintaining 0.02mm dimensional tolerances. This forces local operators to source sub-standard replacements or experience critical machinery downtime.
Haochu Machinery bridges this regional gap by offering high-grade global casting, forging, and precision CNC finishing services. We ship customized high-performance spares, hydraulic couplers, and valve bodies engineered to withstand local conditions direct to logistics depots serving Muhanga and Gitarama.
Bridging advanced metallurgy and CNC technology with global supply chain networks.
Global procurement teams in mining and logistics require components that resist mechanical fatigue under high stress and corrosive operating environments. Our components are cast from custom alloys, including Low-Temperature Carbon Steel (LCC), 45# Carbon Steel, and 6061 Anodized Aluminum. These materials are selected and heat-treated specifically to mitigate hydrogen embrittlement and abrasive wear, ensuring longer service lives for parts deployed in isolated operations.
By integrating investment casting (silica sol process) with precise secondary multi-axis CNC finishing, we eliminate material wastage by up to 35% compared to solid billet machining. This hybrid workflow ensures that complex geometries, such as pump impellers and pipeline fittings, maintain high structural density internally while matching critical contact surface specifications within strict tolerances.
Every batch shipped under our oversight undergoes strict quality testing, including Ultrasonic Flaw Detection, Magnetic Particle Testing (MPI), and Coordinate Measuring Machine (CMM) dimensional verification. All orders are accompanied by complete Material Test Reports (MTR) according to EN 10204 3.1 standards, ensuring full transparency for international compliance audits.
Established in 2013, Ningbo Yinzhou Haochu Machinery Manufacturing Co., Ltd. is a modern manufacturing enterprise specializing in the research, production, and service of casting and forging technologies. Driven by innovation, the company is committed to delivering high-precision machining solutions for industries such as automotive parts, agricultural machinery, valves, and industrial automation.
The company excels through three key strengths:
Our three-tier check system verifies dimensions at three stages: initial tool setup inspection, real-time in-process checks by machine operators, and a final automated audit via Coordinate Measuring Machines prior to packaging and dispatch.

Everything you need to know about custom mechanical manufacturing, export logistics, and shipping components to Rwanda.
We manage logistics from our state-of-the-art facility near Ningbo Port, China, which enables seamless sea freight shipments. For Rwandan clients, we route cargo through either the Northern Corridor (via Mombasa Port, Kenya) or the Central Corridor (via Dar es Salaam Port, Tanzania). From there, transit proceeds by road directly to the customs dry port in Kigali or Muhanga. For urgent sampling or lightweight replacement tooling, we coordinate direct express air courier services (DHL, FedEx, or air cargo networks) directly to Kigali International Airport (KGL), situated less than two hours' transit from Gitarama.
Our lead times are structured to support operational efficiency. Rapid sampling and structural prototyping are completed in 7 to 12 working days. This includes multi-axis CNC programming, sample cast runs, and dimensional validation reports. Full batch production cycles generally range between 25 and 35 days, depending on geometry complexity, selected heat treatments (such as normalizing, oil quenching, or surface gas carburizing), and surface finishing specifications (zinc electroplating, powder coating, or e-coating).
Yes, our engineering department offers full reverse-engineering services. Clients in Gitarama can ship worn or damaged original castings or machined gears directly to our R&D center in China. We utilize laser optical 3D scanners to reconstruct precise digital solid models. Our technicians correct for surface wear and structural fractures, optimization of the component geometry, generation of standard 2D and 3D CAD files (STEP, IGES, and DWG formats), and production of replacement parts that meet or exceed original equipment manufacturer (OEM) performance limits.
We implement a strict raw material sourcing protocol. Every melt batch is analyzed on-site using optical emission spectrometers to guarantee the chemical composition matches standard ASTM, DIN, or JIS specifications. We verify tensile strength, yield strength, impact toughness (Charpy V-Notch tests), and hardness (Rockwell/Brinell scale) post-heat treatment. Third-party certifications from recognized organizations like SGS, TÜV, or Bureau Veritas can be scheduled upon project request.
