Product Development & Manufacturing Process
At ZH Precision, we guide you through a precision-driven full-cycle journey—from CNC-powered rapid prototyping to low-volume production. Every stage is aligned with your telecom components’ functional, performance, and scalability goals, ensuring seamless integration and top-tier quality.
Rapid Prototyping
Early-stage prototypes are critical for validating energy storage & power equipment components—including battery end plates, cooling plates, inverter housings, and structural brackets. Prototyping enables fast design adjustments and material selection, while accurately replicating complex metal geometries required for reliable system integration.
- Fast design and structural iterations to accelerate development cycles
- Precision CNC-machined prototypes for complex metal parts with tight tolerances
- Metallurgical feasibility checks (material compatibility & process adaptability) prior to validation
Engineering Validation & Testing
At this stage, components undergo repeated testing to ensure performance under real-world operating conditions—thermal load, vibration, mechanical stress, and sealing requirements specific to energy storage and critical power equipment. We deliver functional prototypes with precise dimensions and consistent mechanical properties to identify and resolve design risks early.
- Precision machining for dimensionally stable functional prototypes
- Mechanical & thermal performance verification (aligned with energy sector operating conditions)
- Material behavior evaluation for energy-specific harsh environments
Design Validation & Testing
DVT focuses on verifying the final design’s appearance, fit, and performance—using the exact materials and surface treatments required for energy storage & power equipment, such as corrosion-resistant finishes, high-efficiency heat-dissipation surfaces, and stable conductive interfaces.
- Comprehensive appearance, performance & assembly compatibility evaluation
- Wide range of energy-adapted metal materials (aluminum, copper, stainless steel, steel alloys)
- Targeted surface treatments for corrosion resistance and thermal management optimization
Production Validation & Testing
Before mass production, manufacturing processes—including CNC machining, die casting, and metal forming—are validated for repeatability, cost efficiency, and scalability. Tooling, fixtures, process flow, and inspection strategies are finalized to ensure stable, high-quality output.
- Process capability verification (CNC + die-casting + secondary machining operations)
- Tooling and fixturing readiness for low-volume trial production
- Fast delivery of pilot builds with full dimensional inspection reports
Mass Production
Final components enter large-scale production via advanced manufacturing technologies: CNC machining, die casting, sheet metal processing, and metal extrusion. Strict quality control—covering dimensional stability, mechanical performance, and corrosion resistance—ensures parts meet the demanding standards of the energy storage & power sector.
- Comprehensive dimensional, structural & surface quality inspections
- Consistent quality for high-volume production requirements
- Full-range secondary operations (CNC finishing, drilling, tapping, polishing, coating)
- Complete traceability & compliance with energy and industrial application standards

Communications Industry FAQ
Find answers to the most common questions about our telecom component manufacturing capabilities.
A. We produce RF housings, antenna brackets, filter cavities, heat sinks, enclosures, and other precision metal parts for 4G/5G communication equipment.
A. Our tolerance performance is tailored to the manufacturing process, and here are the specific achievable ranges:
- CNC machining: It can stably control the tolerance within ±0.003–0.008 mm. This precision is fully capable of meeting the production needs of key RF and communication parts, avoiding problems such as poor assembly or signal interference caused by size errors.
- Die casting: As a high-efficiency forming process, its tolerance is generally ±0.02–0.1 mm. It is mainly used to produce large structural parts of communication equipment, which can well balance production efficiency and the basic dimensional requirements of parts.
If you have special precision needs, we can combine the two processes to adjust the tolerance to the required level.
3. Yes, we provide fast prototypes based on your 2D/3D files through CNC machining, deburring and cleaning, secondary precision machining, surface finishing, and proper protection before shipping.
A:Yes. We offer free DFM checks to ensure proper heat dissipation, structural stability, and manufacturability for communication components.
A: Aluminum alloys (6061, 6063, A380, ADC12), brass, stainless steel, and other RF-friendly metals depending on weight, strength, and thermal requirements.
