        Dalian Bohai Rubber & Plastics Co., Ltd. has officially unveiled its complete vehicle and construction machinery component supply system.
Recently, Dalian Bohai Rubber & Plastics Co., Ltd. officially unveiled a six‑segment product classification system, comprehensively showcasing the company’s technological expertise and its capability for large‑scale component supply in the automotive and construction‑equipment rubber and plastic parts sectors.
As a specialized enterprise deeply engaged in the manufacturing of rubber and plastic components, the company has established six major product segments that span multiple vehicle systems and construction machinery.
● Steering System Segment: Core components of the steering column assembly—O-rings, dust boots, spherical rubber sleeves, and lower protective rubber sleeves—are supplied for models such as the Tank 330, providing reliable sealing and protection for the steering system.


● Chassis Segment: Rear steering slide‑block bolts for the chassis, supplied in bulk for models such as the L9, L7, and L6, ensuring stable chassis connections through precision forming.

 

● Brake Systems Segment: A specialized fastener assembly for Toyota’s chassis‑brake rigid hydraulic lines, designed to match the Corolla model and ensure braking safety through stringent quality control.

 

● Air Conditioning System Segment: Air-conditioning bracket locating pins and rubber sleeves for air-conditioning piping, supplied for models such as the Elantra and Haval, offering both precise positioning and excellent weather‑resistance and aging‑resistance.

 

● Construction Machinery Segment: Wire harness protective sleeves are being supplied in volume to Komatsu excavators, underscoring the company’s cross‑industry supply‑chain capabilities.

 

● Seat Systems Segment: The seat resonance damper is supplied to BYD Qin, leveraging advanced material formulation technology to effectively suppress resonance and enhance the vehicle’s overall NVH comfort.


Leveraging mature compound formulation expertise and advanced precision mold‑design capabilities, the company’s product portfolio spans four key functional areas—sealing, vibration damping, protection, and fastening—delivering a distinct one‑stop‑solution advantage. Riding the wave of new energy and intelligent technologies, the company will continue to ramp up R&D investment, deepen collaborative development with automakers, and provide customers with safer, more reliable, and cost‑effective elastomer and plastic component solutions.
