Custom Precision Machining Castings Manufacturers & Factory

Leading the Global Supply Chain with High-Integrity Investment Casting & Deep Processing Excellence

The Macro Industry Paradigm: Precision Casting 4.0

In the current global industrial landscape, the demand for Custom Precision Machining Castings has transcended basic manufacturing. It is now a critical intersection of metallurgy, digital design, and high-performance engineering. As industries such as aerospace, new energy vehicles (NEVs), and deep-sea petroleum extraction evolve, the components must withstand extreme thermal fluctuations, corrosive environments, and cyclical mechanical stress.

We are witnessing a shift toward "Zero-Defect Manufacturing." Our factory addresses this by integrating AI-driven simulation software to predict metal flow and solidification, ensuring that every casting is optimized for structural integrity before the first drop of molten steel is poured.

Strategic Position: JUNLONG Machinery Co., Ltd. (founded 2014) serves as a tier-1 and tier-2 supplier to global giants, bridging the gap between raw casting and finished assembly.

Technical Roadmap & Future Outlook

The future of precision machining castings lies in the convergence of the "Lost Wax" tradition and "Smart Manufacturing." Our roadmap focuses on three pillars:

1. Digital Twin Casting

Utilizing digital twins to simulate the thermal dynamics of the investment casting process. This reduces material waste by 15% and ensures internal porosity is virtually eliminated.

2. Green Foundry Initiatives

Implementing closed-loop water systems and advanced dust filtration. Sustainability is no longer optional; it is a requirement for our global partners in the EU and North America.

Full Chain Manufacturing

Full Industrial Chain Integrated Manufacturing

Seamless connection, controllable quality, shorter lead times. From initial design concepts to final product delivery, all key processes are completed in-house:

  • 🚀 Mold Manufacturing: Ensures dimensional accuracy at the source of casting.
  • 🔥 Precision Casting: The core lost wax investment casting process.
  • 🛠️ Machining: Vertical & Horizontal machining centers, CNC lathes, and grinders.
  • Surface Treatment: Meets final appearance and performance requirements (Painting, Plating, Polishing).

Frequently Asked Questions (FAQ)

What tolerances can your precision casting achieve?
Using our advanced lost wax investment casting, we typically achieve tolerances according to ISO 8062-3 DCTG6 to CTG8. For machined surfaces, we can achieve tolerances as tight as ±0.01mm.
Do you provide material certification for stainless steel castings?
Yes, every shipment includes a 3.1 Material Certificate detailing the chemical composition (Spectrometer test) and mechanical properties (Tensile, Hardness, Impact tests).
What is your lead time for custom mold and first sample?
Generally, mold manufacturing takes 15-25 days, and the first article inspection (FAI) samples are delivered within 7-10 days after the mold is completed.
How do you handle post-casting machining?
We operate a full-scale machining workshop. We are not just a foundry; we are an integrated manufacturer that provides horizontal/vertical CNC milling, turning, and grinding to ensure parts are "Ready-to-Assemble."
Are you compliant with international export standards?
Absolutely. We are ISO 9001 and IATF 16949 certified. Our products meet ASTM, DIN, EN, and JIS standards depending on the client’s localized requirements.
