CNC Machined 2-in-1 EV Power Unit Housing Details
1. Automotive-Grade Structural Integrity
Engineered exclusively to withstand the rigorous mechanical stress profiles mandated by global Tier 1 automotive OEM standards. This premium aluminum enclosure is custom-developed for integrated 2-in-1 On-Board Charger (OBC) and DC-DC converter architectures. Utilizing multi-axis CNC precision machining, the housing incorporates an advanced, topologically optimized wall-thickness distribution and integrated structural reinforcement ribs. This design guarantees absolute dimensional stability, zero warpage, and high-frequency vibration resistance under continuous severe powertrain operations.
2. Advanced Thermal Regulation & EMI Shielding
To successfully mitigate the dense thermal dissipation requirements of high-power density electric vehicle (EV) power electronics, the enclosure features precision-milled internal liquid cooling channels. These fluid pathways are engineered with strict geometric tolerances to maximize surface-area thermal contact and prevent localized hotspots. Concurrently, specialized chemical passivation and conductive anodization surface treatments provide an uninterrupted conductive path, ensuring maximum electromagnetic interference (EMI/EMC) attenuation and shielding effectiveness.
3. Zero-Defect Fluid & Ingress Sealing
Engineered for uncompromising reliability in extreme under-hood and under-chassis operating environments. The mating interfaces utilize a microscopic-tolerance O-ring groove profile to eliminate micro-leakage risks. The assembled enclosure ensures absolute, fully auditable compliance with IP67 (static immersion) and IP69K (high-pressure, high-temperature directional washdown) ingress protection standards, establishing a complete barrier against industrial solvents, moisture, and road debris.
Q1. What types of machining services do you offer?
We provide comprehensive CNC turning and milling services. FlexiTurn machines are equipped with 8-station programmable turrets and support both turning and 5-axis milling operations, making them suitable for everything from simple cylindrical parts to complex multi-axis components.
Q2. What materials can you work with?
We machine a wide range of materials including carbon steel, stainless steel, aluminum, plastics, and other engineering-grade materials. If you have a specific material in mind, just send us your requirements and we'll confirm feasibility.
Q3. What is your typical lead time?
Lead times vary depending on part complexity, quantity, and material availability. For prototypes and small-batch runs, we typically deliver within 5–10 business days. For high-volume production, we'll provide a customized schedule after reviewing your drawings. Contact us with your project details for an accurate timeline.
Q4. How do you price your services?
Pricing is based on several factors: material cost, machining time, tooling requirements, setup complexity, and order quantity. We offer competitive rates for both low-volume prototypes and high-volume production runs. Request a quote with your CAD files or drawings and we'll get back to you within 24 hours.
Q5. What quality control measures do you have in place?
We follow strict quality control procedures throughout the machining process. Our CNC systems support programmable precision down to 1 μm, ensuring high accuracy and repeatability. Every batch undergoes dimensional inspection before shipping, and we can provide inspection reports upon request.
