Why Choose Yongzhu for Your Precision Casting Parts?
When you choose Yongzhu Casting as your precision casting supplier, you get more than just raw castings:
Engineering support and DFM
We review your drawings and 3D models and help optimise wall thickness, fillets and transitions to suit precision casting, reducing defects and machining cost.Process comparison, not just one option
For some parts, sand casting, die casting or machining may be more suitable. We can compare options and recommend the most cost-effective route instead of forcing everything into one process.One-stop solution
Tooling, precision casting, CNC machining, surface treatment and inspection are coordinated as a complete package, which simplifies your supply chain.Export experience and documentation
We support overseas customers with export packaging, labels and documentation, and we are comfortable working with international quality and drawing standards.

Faq About Precision Casting
Delving into the world of precision casting? Here are clear answers to your most pressing questions, putting your concerns at ease.
What information do you need for a precision casting quote?
Please send 2D drawings and 3D models, your expected annual quantity, preferred alloy (if known), critical dimensions/tolerances and any special surface or testing requirements.
What is the usual lead time for tooling and first samples?
Typical lead time for tooling and first article samples is several weeks, depending on part complexity and workload. We can give a more accurate estimate after reviewing your drawings.
What is the typical minimum order quantity (MOQ)?
We support small pilot orders for new projects, then help you move to more economical batch sizes as the project stabilises. MOQ depends on part size and process set-up cost.
Can you supply machining and surface treatment together with castings?
Yes. We routinely supply fully machined and finished parts, including drilling/tapping, CNC milling, polishing, coating or plating according to your specifications.
How do you control quality and traceability?
Critical dimensions are checked according to drawing requirements. We can provide material certificates, inspection reports and other documents as requested in your RFQ.
Do you only supply precision castings, or also die cast parts?
We specialise in aluminum and zinc die casting as well as precision casting. For many projects we can propose and compare both options if your design is suitable.
