Dongying Marine Closed-Die Forging Case, Shandong

Case Overview

In the marine industry, a client required high-strength closed-die forged components for critical underwater applications. The parts demanded excellent corrosion resistance, strict dimensional tolerances, and complex geometries to meet stringent safety and performance standards. Jianing Forging was selected to deliver a tailored solution.

Client Challenges

The client faced several difficulties: conventional open-die forging could not achieve the required geometric precision, leading to excessive machining time and material waste. Additionally, the marine environment demanded exceptional fatigue strength and resistance to seawater corrosion, which standard forging processes struggled to guarantee. Delivery schedules were tight, and any quality deviation would cause costly project delays.

Our Solutions

Jianing Forging applied its closed-die forging expertise combined with advanced simulation tools to address these pain points. Custom die designs ensured near-net shapes, reducing machining allowance by over 30%. Specialized alloy selection and controlled thermal treatment enhanced corrosion resistance without compromising mechanical properties. Strict process monitoring and certified quality inspections delivered consistent parts that passed all customer tests on the first batch.

Key Outcomes

The forged components met all dimensional and performance specifications, with a significant reduction in lead time compared to alternative methods. The client achieved lower total cost of ownership due to minimized material waste and streamlined post-processing. This case demonstrates Jianing Forging's capability in delivering reliable marine-grade closed-die forgings for demanding applications.
