When Precision Meets Urgency: How Keepwin Rescued a European Client with 17-4PH Piston Rods

Introduzione
In industrial manufacturing, even one flawed part can trigger costly delays and erode client trust. Therefore, smart buyers seek partners who pair speed e accuracy. This case shows how Keepwin Technology stepped in, fixed a supply crisis, and shipped crack-free 17-4PH high-precision piston rods within 45 days.

The Crisis
First, a European compressor maker discovered visible cracks on piston rods sourced elsewhere. Because the rods were unusable, the project risked penalties and contract breaches. Consequently, the client needed a reliable manufacturer—fast.

Choosing Keepwin
After research and referrals, the client contacted Keepwin. Immediately, our engineers reviewed the drawings, H900 heat-treat spec, and tight tolerances. Next, we proposed a clear production plan backed by strict QA. As a result, the client placed the urgent order with confidence.

Our Fast-Track Workflow
Keepwin matched precision with transparency. Below is the 45-day schedule we shared and met:

1. Days 1-3 – Source certified 17-4PH bars; verify hardness.

2. Days 4-8 – Rough CNC turning, then stress relief.

3. Days 9-18 – Finish turning; OD grind to ±0.005 mm.

4. Days 19-24 – H900 heat treatment; hardness check.

5. Days 25-30 – Straightness and concentricity tests.

6. Days 31-34 – 100 % ultrasonic crack inspection.

7. Days 35-40 – Mirror polish; final dimension confirmation.

8. Days 41-45 – Anti-corrosion packing; export crating.

Throughout production we sent weekly videos, daily photos, e live QA logs. Moreover, every deviation—no matter how small—was reported and approved in real time. Consequently, the client stayed fully informed and shortened their own inspection cycle.

Third-Party Validation
Before shipment, a certified lab checked size, hardness, straightness, concentricity, e surface defects. All rods passed with zero non-conformance. Thus, the parts installed smoothly, without a hitch.

Client Feedback
Soon after installation, Keepwin visited the plant. Because the rods fit perfectly, the client praised both quality e communication. One engineer noted, “It is rare to see a supplier align so well with our QC standards.” That endorsement says it all.
