About the factory
Fuel injection parts manufacturer and exporter based in Guangzhou with our production plant in Jiangxi — supplying distributors, repair workshops and fleet operators across Asia, Europe, the Middle East and the Americas since 2010.
We make the parts, we do not just buy them
Guangzhou Yingfa Construction Machinery Co., Ltd. was founded in 2010. Our head office and export team are in Guangzhou's Zhuji International Machinery City, and our 2,000 m² plant in Jiangxi employs around 30 people on machining, assembly and inspection. We started as a rebuild shop for inline pumps and grew into a manufacturer with our own grinding, lapping and test-bench capability.
That history matters to you for one reason: when a distributor resells a plunger they bought from somebody else, they cannot tell you what steel it is or what clearance it was ground to. We can, because we ground it.
- In-house cylindrical grinding, lapping and super-finishing
- Calibrated pump and injector test benches, incl. Bosch EPS 205
- Factory + trading: our own line, plus verified partner lines for electrics, hydraulics and undercarriage
- OEM and private-label packing for distributors (from 100 pcs)
Three things, done properly
Manufacture
Plungers, barrels, delivery valves and nozzle elements ground and lapped in-house from certified bar stock.
Assemble & calibrate
Complete pumps and injectors built, then calibrated on test benches across the full RPM range.
Export
Packed, photographed and shipped door to door by air express or consolidated sea freight.
Export markets
Regular shipments to these markets — by air express for sample and small orders, consolidated sea freight for container loads.
Shipping from Guangzhou and Shenzhen ports through our long-term freight partners. Door-to-door air express for samples, FOB / CIF for full containers.
An export team that answers fast
Our Guangzhou office handles quotation, English correspondence, export documents and after-sales follow-up, so questions never wait for the factory floor to clock in.
Who buys from us
Four types of buyer, and we have adjusted how we work for each of them.
Parts distributors
Need consistent quality, private-label packing and stable pricing across repeat orders.
Diesel repair shops
Need one piece today, not a pallet next month, and technical answers by email.
Fleet operators
Mining, quarry and construction fleets that buy by the machine model, not by part number.
Importers
Building a local brand and looking for a factory that will not compete against them.
Straight answers, no theatre
If we cannot supply it, we say so
A wrong pump costs you a machine down and a customer. We would rather lose the order.
Photos before shipping
Every order. If the goods are not what you expected, you see it before they fly.
We answer technical questions
Not a call centre. The person who built the part answers the email.
