Maozhong Precision is your dedicated partner for batch production of mission-critical CNC components in electric and high-performance vehicles. We bridge the gap between prototype and volume manufacturing by leveraging Swiss-lathe precision (±0.01mm) and an IATF 16949 certified system. Our focus is delivering consistency, traceability, and assembly-line reliability for parts like battery trays, e-motor housings, and chassis structures, fully supported by PPAP documentation.
Tensile Strength (570 MPa): Matches many steels, crucial for crash-relevant components like battery pack shear plates and suspension uprights.
Fatigue Resistance: Superior performance in dynamic load applications such as engine mounts and control arm links.
Lightweighting: Enables weight reduction without sacrificing safety, directly impacting EV range.
Corrosion Resistance: With proper anodizing, withstands harsh underbody and battery compartment environments.
Electric Vehicle (EV) Battery Pack: End plates, crossmembers, and mounting frames.
Chassis & Suspension: Upper control arms, steering knuckles (for lightweight designs).
Powertrain: High-stress brackets for e-motors and transmission housings.
Single-Setup Machining: A brake caliper piston or fuel injector nozzle is completed in one chucking. This eliminates the cumulative tolerance errors inherent in multi-machine workflows, ensuring perfect concentricity and alignment critical for sealing and function.
Result: Consistent quality part-to-part, essential for automotive assembly line reliability and PPAP (Production Part Approval Process) validation.
Material Savings (90%+): Near-net-shape machining from bar stock drastically reduces waste on expensive materials like 7075 aluminum, making projects like prototype runs and special edition vehicle components financially viable.
Faster Cycle Times: Ideal for batch sizes from 500 to 50,000 pieces – the sweet spot for automotive mid-volume production and model-year updates.
| Challenge in Auto Parts | Traditional CNC | Swiss Lathe at Maozhong | Benefit to You |
|---|---|---|---|
| Multi-axis feature accuracy (e.g., cross-holes in a valve body) | Requires multiple fixtures & setups | All features machined in one setup | Guaranteed ±0.01mm positional accuracy, no misalignment. |
| High-volume consistency | Tool wear leads to drift over a run | Integrated tool wear compensation & in-process monitoring | Cpk > 1.67 capability for critical dimensions, simplifying PPAP. |
| Machining thin-walled parts (e.g., sensor housings) | Vibration causes chatter and variation | Superior rigidity and support of bar stock | Flawless finishes, maintained wall thickness as thin as 0.5mm. |
E-Motor Housings & End Caps: Precision-bored for bearing fits and coolant channels, ensuring thermal management and NVH performance.
Transmission & Gearbox Components: Valve bodies, shift forks, and custom fasteners requiring high wear resistance and dimensional stability.
Power Electronics Brackets & Enclosures: EMI/RFI shielding considerations, with integrated cooling fins and precise mounting faces for inverters and DC-DC converters.
Lightweight Control Arms & Links: Machined from solid billet for strength, with optimized topology to reduce unsprung mass.
Steering Knuckles & Uprights: Critical safety components where material integrity and fatigue life are paramount.
Brake System Components: Non-wearing parts like caliper brackets and pedal box assemblies, machined for absolute rigidity.
EV Battery Pack & Frame Components: Modules, end plates, and mounting systems designed for crashworthiness, with precise sealing surfaces.
Advanced Driver-Assistance Systems (ADAS) Mounts: Rigid, vibration-damped brackets for LiDAR, radar, and cameras, requiring thermal stability.
High-End Interior & Seating Structures: Visible or tactile components where surface finish (e.g., Class-A anodizing) is as important as fit.
Hard Anodizing (Type III): For wear-resistant surfaces on shafts and pins (e.g., HV500+).
Chemical Film Conversion Coatings: For electrical conductivity and paint adhesion on battery busbars and enclosures.
Passivation & Electropolishing: For stainless steel fuel system or hydraulic components to prevent corrosion.
Advanced Metrology: In-line CMM (2.8µm) and vision systems for 100% critical dimension verification on high-volume runs.
Full Traceability: Lot-controlled materials with Mill Certificates, and full Dimensional & Material Reports (FAI) for every part number revision.
Process Control: Statistical Process Control (SPC) charts monitor key production characteristics to preempt deviations.
PPAP & APQP Support: We actively participate in your Advanced Product Quality Planning process, delivering all required documentation (PSW, DFMEA, control plans).
Just-In-Time (JIT) Delivery: Flexible production scheduling and kanban systems to support your assembly line needs.
Challenge: Achieve a 30% weight reduction versus a cast design, maintain IP67 sealing, and deliver a functional prototype in 3 weeks for crash testing.
Solution: DFMA (Design for Manufacture & Assembly) review led to a two-piece CNC-machined 6061-T6 design with integrated cooling channels and an O-groove. Swiss-lathe machining ensured sealing surface flatness.
Result: Prototype delivered in 18 days. Enclosure passed all thermal cycling and crash simulations, and became the foundation for the production design.
Electric Vehicles (EVs): Battery components, e-drive housings, lightweight structural brackets.
Commercial & Heavy Vehicles: Durable chassis components, sensor mounts for autonomous systems.
Performance & Motorsports: Ultra-lightweight, high-strength suspension and drivetrain parts.
A: Yes, we are IATF 16949:2016 certified. Supporting full PPAP submissions (Level 1-5) is standard for our automotive projects. We provide all necessary documentation, including DFMEA, PFMEA, control plans, and capability studies.
A: We have extensive experience machining components that are part of the vehicle’s crash management system, such as battery pack structures and chassis reinforcements. We employ stringent non-destructive testing (NDT) protocols and material traceability to meet these critical requirements.
A: Absolutely. Our Swiss-lathe technology is uniquely efficient for prototypes (1-50 pieces) and low-to-medium volume production (500-50,000 pieces). For very high volumes, we partner with trusted suppliers for processes like casting or stamping, and handle the critical precision machining in-house.
