Automotive Industry Solutions

Ningbo Henghe Precision Industry Co., Ltd. has a deep presence in the new energy and intelligent vehicle sectors. Leveraging over 30 years of experience in precision transmission module R&D and manufacturing, the company focuses on two core areas: automotive lightweighting and intelligent cockpits, providing high-reliability precision components and system modules to OEMs and Tier 1 component suppliers.

 

Following the trends of automotive lightweighting, electrification, and intelligentization, the company has mastered core processes such as plastic-to-steel replacement, steel-plastic composites, multi-insert injection molding, high-precision gears, gearboxes, and automotive actuators. It possesses full-chain capabilities from requirement definition, simulation design, mold development, material selection, sample verification to mass production and assembly. With three production bases in Cixi, Jiaxing, and Dongguan, and two R&D centers, the company meets the stringent IATF16949 quality system requirements of the automotive industry. Its products are compatible with mainstream new energy and traditional fuel vehicles, and it has already served leading companies such as BYD, Geely, JK, SAIC, Leapmotor, Yanfeng, and Huawei.

Ningbo Henghe Precision Industry Co., Ltd. not only delivers parts, but also provides customized precision manufacturing solutions for automotive scenarios, taking into account vehicle-level performance indicators such as weight reduction and cost reduction, NVH quietness, durability and life, environmental weather resistance, waterproofing and dustproofing, helping customers shorten project development cycles and accelerate the mass production of new models.

Our Solution

Automotive Lightweight Assembly Solution

Automotive Lightweight Assembly Solution (For OEMs/Tier 1 Suppliers)

Addressing the need for weight reduction and energy efficiency improvement in vehicles, this solution offers a comprehensive approach to large body components using a steel-plastic integrated design and all-plastic construction.

Early Intervention

Discussion of vehicle lightweighting solutions, material selection, structural simulation optimization, and feasibility assessment of replacing steel with plastic.

Molding and Manufacturing

Injection molding of large components, steel-plastic composite integrated molding, and assembly.

Verification and Delivery

Comprehensive on-board testing for durability, high and low temperatures, vibration, and environmental aging; mass production supply; and support for simultaneous project development and SOP delivery.

Core Value

20-30% weight reduction in body components, lower overall vehicle manufacturing costs, shorter component development cycles, and improved range requirements for new energy vehicles.

Precision Transmission & Actuator Solutions for Smart Cockpits

Providing integrated development and manufacturing of gears, gearboxes, and actuator modules for smart cockpit motion mechanisms.

Requirement Breakdown

Defining specifications for torque, noise, service life, ingress protection (water/dust), and operating temperatures.

Solution Design

Gear transmission schemes, structural design, material selection, and customizable automotive actuator development.

Prototype Fabrication

Rapid prototyping, NVH (noise) testing, durability cycle testing, and environmental reliability validation.

Tooling & Mass Production

Precision tooling, injection molding, gear machining, and module assembly; delivering finished modules.

Core Value

Enables import substitution; features low noise and high durability; suitable for smart motion mechanisms such as seats, rotating screens, fuel filler flaps, and motorized swing doors; direct delivery of finished modules reduces secondary assembly steps for customers.

Automotive Precision Structural Components & Specialty Material Parts

Providing custom solutions for complex injection molding, insert molding, and specialty engineering plastic parts for EV powertrains (battery, motor, control systems) and vehicle body functional components.

Material Matching

Selection of automotive-grade materials such as PP, modified nylon, PC/ABS, and PEEK.

Process Implementation

Multi-insert molding and metal-plastic composite molding to meet requirements for insulation, high-temperature resistance, and corrosion resistance.

End-to-End Quality Control

IATF16949-compliant system, full dimensional inspection, and reliability validation.

Batch delivery of small-to-medium-sized parts; supports custom development based on blueprints.

End-to-End ODM Collaborative Development Services

Henghe Precision provides one-stop ODM services from concept to mass production.

Requirement Input → Simulation & Design → DFMEA Risk Assessment → Tooling Development → Sample Validation → Small-batch Trial Production → SOP Mass Production → Assembly & Delivery

Supports customer-provided concepts/blueprints; we handle structural optimization and component manufacturing.

Supports joint development; deep involvement in the early-stage R&D of new vehicle models.

Three major manufacturing bases allow for flexible capacity allocation, ensuring project delivery schedules and supply chain stability.
