Shenzhen Partix Auto Co., Ltd. — National High-Tech & Tier-1 Manufacturing
Shenzhen Partix Auto Co., Ltd. sits in Zhucheng, Shandong. This spot lies close to Weifang, known as the kite capital. Moreover, it falls within the one-hour circle around Qingdao. As a result, transportation stays easy and quick.
People founded Partix Auto back in 2004. Today, others see it as a national high-tech company. It also counts as a state-owned holding listed firm. The team pushes hard on new ideas. Because of that, Partix Auto won the title of "National Intellectual Property Demonstration Enterprise." And since 2006, experts have regularly named it among the "National Top 100 Automotive Parts Suppliers."
Partix Auto leads strongly in China's automotive parts field. The company mainly designs and builds top-grade fluid pipelines. It also makes car suspension systems and produces rubber parts that reduce vibration. In general, its main products include bushings, air spring products, engine mounts, fluid line system products, thrust rods, and car suspension systems. These items are widely used in passenger cars, commercial vehicles, and engineering machinery.
Engineering the transfer of extreme torque under variable angles with zero vibration transfer
Utilizing high-frequency induction hardened alloys to resist high axial loading. Specially engineered to guarantee linear rotational speeds at varying steering angles, reducing dynamic fatigue in commercial transaxles.
Integrated rubber-to-metal bonding tech blocks structural vibrations originating in the gearbox. Effectively dampens driveline resonance (NVH) under sudden acceleration profiles.
Forged from high-tensile steel with precision-ground needle bearings. Pre-greased with high-temp synthetic lubricants to withstand rigorous continuous torque shifts without degradation.

| CV Joint Outer Race | 50CrMnSi / 20CrMnTi | ≥ 1050 | Front-Wheel Drive Drivetrains | Mechanical Noise Reduction < 40dB |
| Center Support Bearings | EPDM High-Density Rubber + Q235 | N/A (Elastomeric) | Multi-piece Propeller Shafts | Absorption of 92% of Torsional Resonance |
Steering the next generation of lightweight, ultra-torque drivetrains and smart chassis systems
As the global automotive industry moves towards battery electric vehicles (BEVs) and hydrogen fuel cell powertrains, the demands on the driveshaft components have dramatically evolved. Electric vehicles release peak torque instantaneously at 0 RPM, exerting immense torsional stress on CV joints, splines, and coupling shafts. Our engineering roadmap targets three core technological revolutions:
We are designing lightweight carbon fiber reinforced polymer (CFRP) tubes bonded to aluminum yokes. This reduces rotational inertia by up to 60%, drastically improving EV range and drivetrain response times.
By integrating piezo-resistive sensor grids directly into rubber-metal mounts, future chassis systems will monitor dynamic stress loads, sending real-time structural health status directly to the vehicle's ECU.
In line with global decarbonization goals, we are replacing traditional vulcanization accelerators with bio-based elastomer modifiers, cutting the carbon footprint of rubber-to-metal bonding by 35%.
Supplying heavy engineering, transcontinental logistics, and high-speed passenger fleets
Long-haul transit requires parts that can withstand million-mile duty cycles. Our heavy-duty thrust rods and air cabin suspensions prevent structural fatigue in commercial truck cabins, shielding drivers from repetitive stress injury and keeping logistics fleets moving.
With the added weight of under-floor battery packs, electric vehicles run at higher static loads. Our active air spring systems adjust vehicle ride height dynamically, lowering aerodynamic drag by up to 8% at cruising speed.
Debris, mud, and intense impact forces require rugged sealing systems. Our proprietary multi-lip elastomeric boots seal out contaminants, retaining specialized synthetic grease even under severe angle operations.
Leveraging state-of-the-art smart systems for unmatched cost-to-performance metrics
By deploying automated robotic arm cells and closed-die forging setups, we eliminate human variability in the metal-forming process. Our rubber-to-metal vulcanization processes monitor temperatures in real-time, ensuring uniform adhesion strength across every single production run.
Situated in the Zhucheng industrial zone within a 1-hour transport radius to Qingdao Port, we offer international OEM buyers unmatched shipping agility. Our direct logistics corridor guarantees raw material sourcing speed and reduces container dispatch times down to days instead of weeks.
Simplifying cross-border engineering transactions with absolute legal and technical compliance
Our production facilities align completely with IATF 16949 automotive standards. This guarantees that all batches—from sample phase to high-volume production—maintain zero defect targets via structured PPAP documentation.
All raw rubber formulations, surface anti-corrosion platings, and chemical additives are fully compliant with EU and North American environmental rules. We strictly avoid hazardous compounds in our vulcanization processes.
Our R&D team provides complete support using CATIA and SolidWorks. We can analyze custom vibration profiles and run FEA testing on CAD files before tooling investment begins, ensuring first-time-fit accuracy.
Technical explanations and procurement guidance straight from our engineering team
For high-torque applications, we primarily utilize carbon steel alloys like 40Cr and 20CrMnTi, along with premium AISI 4140 Chromoly Steel. These metals undergo induction hardening to achieve a surface hardness of HRC 58-62, providing excellent torsional yield strength and fatigue resistance.
Our rubber-to-metal bonding process utilizes specialized adhesive coating machines followed by precise injection molding. We conduct daily dynamic vulcanization tests, fatigue limit tests up to 3 million cycles, and adhesive peel tests to ensure the elastomer never separates from the metal casing under severe working loads.
Yes. We reverse-engineer and manufacture premium replacement air springs matching or exceeding OE specifications (e.g., LR176316, LR176317). We use imported Cord Compound rubber sheets to ensure extreme pressure containment, anti-sag properties, and long-term durability in cold-weather conditions.
PA11 and PA12 nylon tubes offer exceptional chemical resistance to modern bio-fuels and hydrocarbons. They feature low permeation rates, high impact resistance at sub-zero temperatures, and are lightweight compared to traditional steel lines, helping modern passenger cars meet strict emission guidelines.
For new tooling designs (OEM/ODM), standard prototyping and sample validation take 30 to 45 days. Once PPAP samples are approved, mass production orders are typically fulfilled and dispatched to Qingdao Port within 30 days, depending on the order volume.
