The company can design specialized tooling and fixtures based on part characteristics to ensure machining accuracy and production efficiency.

MH is proficient in five-axis machining, micro-machining, and complex part assembly processes, enabling efficient completion of mass production tasks. The production process covers cutting, milling, boring, grinding, and assembly, ensuring that each part meets stringent technical specifications. MH also has experience in producing high-pressure components, capable of stably machining critical components for hydraulic, fuel, and gas systems at pressures up to tens of MPa.

Applicable Products: Five-axis machined parts, Micro Machining, Downhole Tools MWD Components, Hydraulic valves, Quick Couplings.

MH manufactures high precision Micro Gears like DIN5-8 custom precision gears based on customer drawings, samples, or technical specifications. We supply micro gears for Robot, Aerospace, Medical device, Industrial automation

• Micro spur gears
• Micro helical gears
• Micro bevel gears
• Micro gear shafts

Before quotation, MH can review gear drawings, material requirements, accuracy grade, heat treatment, inspection method, and application background to evaluate manufacturability.

MH supports high geometric tolerance machining for precision parts where coaxiality, cylindricity, perpendicularity, and flatness directly affect assembly accuracy, sealing performance, rotation stability, and service life.

Typical achievable capability examples include:

- Coaxiality: 0.003 mm

- Cylindricity: 0.002 mm

- Perpendicularity: 0.005 mm

- Flatness: 0.005 mm

Final tolerance capability depends on part size, material, structure, machining process, heat treatment, and inspection method. MH recommends drawing review before confirming manufacturability and tolerance control strategy.

MH has dozens of 5-axis machining center like Mazak i600, DMU50 and strong ability for 5-axis machining complex precision components. 5-axis machining helps reduce repeated clamping, improve positioning accuracy, and support complex part structures with multiple surfaces, difficult angles, or strict geometric relationships.

For MWD and downhole tool components, machining quality can directly affect sealing, assembly fit, vibration resistance, and long-term reliability. 5-axis machining and tight process control help reduce accumulated positioning error and improve manufacturing stability for complex functional parts.

Equipped with top listed machines like Mazak FJV-250, DMG DMU50, and OKK HM1250S etc. combined with professional tooling and precision processes, MH achieves stable machining with extremely low dimensional and geometric tolerances.

MH is familiar with the special processes of machining thin-walled parts, ensuring high dimensional accuracy and part strength, and is suitable for the production of high-pressure components such as aerospace hydraulic quick couplings and valve assemblies.

Relying on high-precision CNC machine tools and precision testing equipment, combined with years of experience in manufacturing high-pressure components, MH can reliably complete the machining of complex thin-walled structures.

Applicable Products: All miniature parts, hydraulic valves, solenoid valves, filters, and filtration devices.

MH is certified by international standards including AS9100, ISO14001, and ISO45001, and possesses a CNAS-accredited laboratory and a comprehensive quality control system.

MH implements Total Productive Maintenance (TPM) lean manufacturing management and operates with an aerospace-oriented quality management system to ensure efficient, stable, and traceable production processes.

For over 30 years, MH has provided critical component processing and assembly services to global aerospace companies, offshore oil and gas exploration equipment manufacturers, and hydraulic fluid systems companies, earning high customer recognition.

Quality management is integrated throughout the entire production process, from incoming parts inspection and online process control to finished product testing, ensuring that every miniature part, miniature gear, and hydraulic/pneumatic component meets the most stringent standards.

MH has long-term OEM manufacturing experience for international customers in demanding industries, including oilfield equipment, food packaging machinery, fluid control systems, aerospace-related components, and precision mechanical assemblies.

This experience helps MH understand overseas customers' requirements for:

• Drawing-based custom manufacturing
• Technical clarification before quotation
• Sample validation
• Quality documentation
• Export packaging
• Batch consistency
• Long-term supplier cooperation
• Communication with engineering and purchasing teams

MH is suitable for customers looking for a reliable manufacturer for high-precision custom components, not only a low-price parts supplier.
