About TRANSMITEK
Welcome to TRANSMITEK
The company was founded in 1996 and is headquartered in Ruian.We provide OEM/ODM services.
Hydraulic clutch cylinder and cardan shaft products are our core business. We are one of the top three hydraulic clutch cylinder and propshaft manufacturers in China and have more than 30 years of industry professional experience.
High Pressure Fuel Pump (HPFP) is our product project for the past five years. In view of the technical barriers that other suppliers in the Chinese market are difficult to solve, the company’s technical team has risen to the challenge and tackled the technology.The stable and reliable product quality has won unanimous praise from internationally renowned brand customers.
Passed IATF16949 in 2000; introduced ERP management in 2009; introduced MES intelligence management system in 2020, and passed the national CNAS quality inspection certification (ISO17025) in 2023…
More than 92% are directly exported to oversea markets, covering more than 50 countries and regions including Germany, the United States, Mexico, Brazil, Russia, Australia, South Africa, etc…
We have been focusing on hydraulic technology for 30 years. Compared with other Chinese manufacturers, our advantage is stable and reliable product quality. Such as Clutch Release Bearing project, cause many of competitors started with bearings. In fact, the real technical difficulty of the CSC (concentric slave cylinder, clutch) lies in hydraulics. As for the High Pressure Fuel Pump project, we also use our own technical advantages to solve the technical difficulties that are difficult for Chinese factories to solve.
We have long-term and stable cooperation with about 86% international brands and have won reputation with quality.
Who We Are?
At Transmitek, we specialize in High Pressure Fuel Pumps engineered for the world’s most demanding automotive and industrial applications.
With over 30 years of hydraulic engineering expertise, we understand the physics behind HPFP performance at a depth rarely found in the Chinese supply chain, including:
- lubrication-film stability
- micro-seizing behavior
- thermal deformation
- surface-finish integrity
- plunger–barrel clearance dynamics
- high-pressure load transfer
This engineering foundation defines who we are and how we work.
What Makes Us Different — We Are an Engineering System, Not a Factory
Most suppliers focus on meeting specifications.
We focus on removing the mechanisms of failure.We built an engineering system around three pillars:
1. Precision Control
Ensuring the physical conditions under which failure cannot occur:
- micron-level plunger–barrel clearance engineering
- SPC-controlled tolerance stability
- robotic assembly for hydraulic interfaces
- controlled surface-finish processes that prevent lubrication-film collapse
2. Failure-Mode Elimination
Addressing issues most factories cannot diagnose, let alone solve:
- micro-seizing reproduction & root-cause elimination
- coating endurance simulation & wear-pattern prediction
- pressure-wave stability engineering
- thermal-cycle deformation analysis
- validation of lubrication integrity under extreme operating conditions
3. Validation-Driven Manufacturing
A production system designed not to react to failures, but to prevent them:
- ISO 17025–aligned laboratory verification
- endurance & environmental simulation before release
- digital traceability ensuring zero drift across batches
- full recorded testing data for every pump
Why Fortune Global 500 brand & Internationally renowned brand Trust Us
Because we deliver what most HPFP suppliers cannot:
- Stable pressure output across every batch
- Micron-consistent precision that prevents sticking & drift
- Validated endurance performance under real-world loads
- Zero-drift mass production enabled by digital process control
- Engineering transparency and traceability at every step
This is not marketing—it is what allows our customers to reduce risk, avoid field failures, and maintain supply-chain stability at scale.
The same engineering system supports our driveshaft and hydraulic clutch cylinder products, governed by the same principles of high-precision dynamics, hydraulic technology, wear stability, and long-term endurance.
Long-Term Partnerships That Prove Reliability
Our customers do not stay because of pricing.
They stay because our engineering protects their products, their supply chain, and their reputation.
90%Â reorder rate sustained over decades
30% of clients have partnered with us for 20–30 years
35% have stayed with us for 10–20 years
These results are not accidental.
They are the natural outcome of consistency, engineering integrity, and proven field performance.
Once customers adopt our components,
we become their long-term engineering partner—not just a factory/supplier.
Our Mission — Setting the Reliability Benchmark
- To set the engineering standard for HPFP reliability in China.
- To eliminate hidden risks across the supply chain
- To deliver validated performance that endures in real applications
- To help global partners operate with confidence for decades.

About the company
About Developing & Testing
We mainly export directly. The current share is about 92%, and the domestic market accounts for 8%.Â
The main export markets are: America 28%, especially Brazil and Mexico in South America; Europe 28%, Russia,and some Asia Pacific regions...
Of course, we mainly supply to some big international brands, especially the world's top 500 brands.
IATF 16949, ISO 14001,ISO 45001, (CNAS)ISO/IEC 17025.
Our company has been exporting overseas directly since 2000. Before that, we exported through some trading companies.
There are 600 employees. Currently, it operates in two shifts.
Only aftermarket. OE just does a little bit for a domestic OEM.
We are willing to develop products related to our current product range. Generally, the quantity is 200-500 pieces, and the specific quantity depends on the complexity of the product.
Not necessarily. We will analyze it based on the structure of the sample. The appearance basically follows OE, but the internal design follows our own technology. We ensure that the product's usage function and quality are completely OKAY.
