The Honjenny Integrated Advantage

Why leading OEMs choose our "Cast + Machine" integrated service.

  • Single Point of Accountability

    With Honjenny managing both casting and machining, there is no more finger-pointing between suppliers. We take full responsibility for the final part quality.

  • Smart Tolerance Management

    We design molds with machining in mind. By optimizing the "Near-Net Shape," we reduce material removal volume and shorten cycle times significantly.

  • Logistics & Cost Efficiency

    Eliminating transportation between casting and machining facilities reduces lead times by [1-2 weeks] and minimizes the risk of shipping damage.

Industries We Serve

From rugged automotive components to delicate electronic enclosures, our secondary machining meets the diverse needs of global industries.

What Our Customers Say

Real feedback from engineers and procurement managers.

“Moving our secondary machining to Honjenny was a game-changer. They solved the alignment issues we had with previous suppliers, and the surface finish is excellent.”

Mark Anderson
Sr. Mechanical Engineer

“We had a complex housing design requiring angled drilling that our previous supplier struggled to hold. Honjenny utilized their 5-axis machining capability to hit the true position tolerances perfectly every time. Their engineering team really understands the nuances of machining die-cast materials.”

David Miller
Product Design Lead

“Consolidating our casting and finishing with Honjenny was a strategic move. We eliminated the shipping costs between the foundry and the machine shop, and the communication is so much smoother. They just deliver the finished part, ready for our assembly line.”

Sarah Jenkins
Supply Chain Director

Project Workflow

From raw concept to precision part in 3 simple steps.

01

Design Review & DFM
We analyze your 3D drawings to determine the optimal balance between as-cast features and machined features to save costs.

02

Fixture Development
Our engineering team designs custom holding fixtures to ensure the part remains rigid and deformation-free during high-speed cutting.

03

Precision Production
Parts move directly from casting to machining. Strict QC protocols (CMM, Go/No-Go gauges) ensure every dimension meets print specs.

Frequently asked questions

For critical features like bearing bores or shaft fits, we can hold tolerances as tight as ±0.0015mm. For general linear dimensions, we follow ISO 2768-m or your specific drawing requirements.

We design custom fixtures (often using pneumatic or hydraulic clamping) that distribute pressure evenly. We also use “low-stress” machining strategies to prevent part warping.

Our primary focus is providing a total solution (Casting + Machining) to ensure quality accountability. However, we evaluate “machining-only” projects on a case-by-case basis.

Yes, we offer a full range of post-machining finishes, including Powder Coating, Anodizing, E-coating, and Chromate conversion, ensuring the machined areas are properly protected.

We use automated rigid tapping and thread milling. We perform 100% gauging checks (using Go/No-Go gauges) on critical threads to prevent assembly issues.

With our fleet of 70 CNC centers and automated robotic loading options, we can handle volumes from 1,000 to 500,000+ parts per year with consistent quality.
