Your oil pump drawing becomes a finished part in as little as 7 days. We machine it to your exact geometry, verify every critical dimension, and ship with a full inspection report. No surprises.
We are a precision manufacturing factory in Dongguan, China, with 20 years of CNC machining experience. You send the drawing. We handle the rest.

| Inspection | CMM reports, optical comparators, air gauges, 100% critical dimension check |
| Lead time | Prototype 7 days; production 10–15 days after approval |
Every part is machined from certified raw material. We do not substitute grades without your written approval.
1. Batch-traceable quality Each batch gets a unique job number. We track material heat number, machine operator, tooling, and inspection results. If a problem appears in your assembly line, we trace it to the exact shift and cutting tool. This is not optional—it is our standard workflow.
2. Inspection report per batch You receive a full dimensional report with every shipment. Critical features (bore diameters, concentricity, surface finish) are measured and documented. We also provide material certificates and, on request, first-article inspection reports with CMM data. No extra charge.
3. One factory for CNC + stamping + springs + heat sinks Your oil pump assembly may need a machined housing, a stamped cover plate, a compression spring, and a heat sink for the motor drive. We make all of them under one roof. You deal with one engineer, one quality system, one shipping point. This cuts your supplier management time and reduces tolerance stack-up issues between components.
CNC machined oil pump parts go into systems where pressure stability and leak-free operation are non-negotiable. Typical applications include:
These parts often run at 3,000–6,000 RPM with oil pressures up to 10 bar. Wall thickness, bore roundness, and surface finish directly affect pump efficiency and noise. We machine to the tolerances your design requires, not just what is "easy."

Q: What is your MOQ? A: No MOQ. We machine single prototype pieces and million-piece production runs. Tooling and setup costs are quoted transparently per order.
Q: How do you guarantee tolerance and quality? A: We use in-process probing on CNC machines, then verify with CMM on a sampling plan agreed with you. Critical dimensions are 100% inspected. You get the data.
Q: What is the lead time for a custom oil pump part? A: Prototype in 7 days after drawing approval. Production batches in 10–15 days. For urgent needs, we can split the batch and ship partial quantities.
Q: Do you provide material certificates? A: Yes. EN 10204 3.1 material certificates are included free with every shipment. Additional certs (e.g., heat treatment reports) are available on request.
