PRECISION TUBE SOLUTIONS FOR PASSENGER CARS
Passenger vehicle components must balance multiple requirements at the same time: structural safety, lightweighting, dimensional accuracy, durability, efficient assembly, and cost-effective mass production. As vehicle platforms continue to evolve toward electrification and greater integration, these requirements are becoming increasingly demanding.
CBIES supports passenger car OEMs and Tier 1 suppliers with precision steel tubes and processed tube components for safety, structural, seating, suspension, exhaust and EV applications. By combining tube manufacturing with bending, stamping, hydroforming, end forming and other downstream processes, we help turn material and design requirements into production-ready tube solutions.
OUR COMPONENTS FOR PASSENGER VEHICLE APPLICATIONS
Side Impact Beams
Engineered for crash protection without unnecessary weight.
Side-impact beams need to provide reliable structural protection while meeting increasingly demanding vehicle lightweighting and packaging requirements. Optimized tube geometry, suitable material selection, and controlled tube-forming processes can help achieve the required balance between side-impact performance and structural weight.
● Crash Protection
Supports the structural requirements of vehicle impact protection and occupant safety.
● Weight Optimization
Optimized tube structures help reduce unnecessary weight while maintaining required structural performance.
● Reliable Mass Production
Stable forming and manufacturing processes support consistent quality across high-volume production.
CBIES supports the production of tube-based side-impact beams through precision tube manufacturing and downstream forming processes tailored to specific passenger vehicle and component requirements.
Battery Pack Brackets
Supporting battery structures while helping optimize EV weight and assembly.
Battery pack brackets play an important role in securing and supporting battery systems. They must provide reliable structural support while maintaining dimensional accuracy for efficient integration into the battery pack and vehicle structure.
● Battery Protection & Structural Support
Provides reliable support for battery systems and helps maintain structural integrity under demanding vehicle conditions.
● Weight Optimization
Efficient tube structures help reduce unnecessary structural mass, supporting overall EV lightweighting and energy efficiency.
● Assembly Accuracy
Controlled dimensions and forming accuracy support reliable positioning, fit-up, and assembly of battery-related components.
CBIES combines precision tube manufacturing with bending, laser-cutting, and other processes to develop tube-based battery support components according to project-specific requirements.
Shock Absorber Tubes
Precision tubes for consistent damping performance and long-term durability.
Shock absorber tubes operate under repeated movement and demanding service conditions. Dimensional consistency, surface quality, and material performance are essential to maintaining reliable operation throughout the component's service life.
● Damping Performance
Controlled tube dimensions and surface characteristics support consistent piston movement and damping operation.
● Long Service Life
Suitable materials and controlled manufacturing processes help withstand repeated mechanical loading and long-term operating conditions.
● Dimensional & Surface Precision
Consistent ID, OD, straightness, and surface quality support reliable internal component fit and functional performance.
CBIES manufactures processed tube parts with controlled dimensional and surface characteristics for suspension and shock absorber applications.
Exhaust Components
Built for demanding thermal environments, complex forming and cost-efficient production.
Exhaust tubes must withstand high temperatures, thermal cycling and corrosive environments while accommodating complex routing and vehicle packaging requirements. Efficient manufacturing is equally important for high-volume automotive production.
● Thermal & Corrosion Durability
Material and surface solutions are selected to withstand heat, thermal cycling and corrosive operating conditions.
● Forming Flexibility
Processed exhaust system components can meet complex geometries, packaging and connection requirements.
● Weight & Cost Efficiency
Optimized materials, tube dimensions and manufacturing processes help balance performance, weight and production cost.
CBIES supports exhaust tube production with precision tube manufacturing and through precision hydroforming, end forming and welding for complex exhaust geometries.
Seat Components
Strong, lightweight tube structures for safer and more space-efficient seating systems.
Seat structures must combine structural strength and occupant safety with low weight, compact packaging and efficient assembly. CBIES seat system components can provide an effective balance between structural performance and weight when geometry and manufacturing processes are properly optimized.
● Safety & Structural Strength
Provides the structural support required for reliable seat performance.
● Weight Reduction
Custom seat tube parts can reduce unnecessary material and weight while maintaining required structural performance.
● Packaging & Assembly Efficiency
Formed tube components support compact seat designs and efficient integration with surrounding mechanisms and vehicle structures.
CBIES provides precision tube components for seat structures, with bending, stamping, welding, and other processes available to meet different seat design requirements.
Cross Car Beams
Engineered for cockpit rigidity, NVH performance and targeted mass reduction.
Cross car beams serve as a structural backbone for the dashboard and can support multiple vehicle systems and components. Their design must balance rigidity, weight, packaging and integration requirements while maintaining reliable assembly accuracy.
● Cockpit Structural Rigidity
Provides robust mounting interfaces for the steering column, passenger airbag, HVAC, and dashboard assemblies, maintaining cockpit integrity under crash‑load conditions.
● Weight Optimization
Our steel tube parts help reduce weight without compromising required rigidity.
● NVH & System Integration
Controlled structural characteristics and accurate mounting interfaces support system integration and help address noise, vibration, and harshness requirements.
CBIES manufactures and processes precision tube components for cross-car beam applications, supporting complex geometries, mounting interfaces and project-specific dimensional requirements.
Built Around Your Passenger Car Requirements
Passenger car tube applications rarely have a one-size-fits-all solution. Material grade, tube dimensions, geometry, forming method, joining process, surface treatment, and quality requirements all need to work together around the final application.
The product examples and visuals shown above serve only as representative references of our delivered projects. Beyond these showcased components, we are also capable of developing and manufacturing many other custom tubular parts, such as automotive air-conditioning system tubes and intake pipes, to meet diversified application demands across vehicle systems.
