What information do you need for a precision casting quote?

For a precision casting quote, please provide 2D drawings and 3D models, expected annual quantity, preferred alloy if known, critical dimensions and tolerances, and any special surface, testing or documentation requirements.

What is the usual lead time for precision casting tooling and first samples?

Typical lead time for precision casting tooling and first article samples is several weeks, depending on part complexity and current workload. A more accurate schedule can be confirmed after we review your drawings and 3D models.

What is the typical minimum order quantity for precision castings?

Minimum order quantity for precision castings depends on part size, tooling and set-up cost. We support small pilot runs for new projects and can recommend economic batch sizes once your demand forecast is clear.

Can you supply machining and surface treatment together with precision castings?

Yes. Yongzhu Casting can deliver fully machined and finished precision castings, including CNC machining, drilling and tapping, polishing or blasting, and coatings or plating according to your specifications.

How do you control the quality of precision cast parts?

Critical dimensions on precision cast parts are checked with gauges and CMM where required. We can provide material certificates, dimensional inspection reports and other quality documents to match your drawing and project requirements.

Do you also offer die casting in addition to precision casting?

Yes. In addition to precision casting, Yongzhu Casting supplies aluminum and zinc die cast parts with CNC machining and finishing. For suitable designs we can compare precision casting and die casting and recommend the most cost-effective process.

For Complex Aluminum Parts with Better Detail

Precision casting is often used when aluminum parts have complex shapes, fine details, thinner walls, or surface requirements that are difficult to achieve with simple machining or rougher casting processes. It can help produce near-net-shape parts and reduce machining work in some areas.

Your Part Requirement	How Precision Casting Helps
Complex shape	Helps form details that are difficult with simple machining or sand casting
Fine details	Suitable for small features, curves, slots, and detailed structures
Better surface	Provides smoother casting surfaces than many conventional casting methods
Less machining	Near-net shape can reduce machining work in some areas
Custom design	Suitable for parts made from 2D drawings, 3D files, or samples
Secondary finishing	Machining, polishing, heat treatment, or surface treatment can be arranged

Precision Casting FAQ

Is precision casting the same as investment casting?

In many manufacturing projects, precision casting usually refers to investment casting or lost wax casting. It is used to produce metal parts with complex shapes, fine details, and better surface quality.

Can you quote without a complete drawing?

Yes. You can send sample photos, rough dimensions, material information, and estimated quantity first. A complete drawing or 3D file helps us review the project more accurately.

Do you mainly produce aluminum precision casting parts?

Yes. Our page focuses on custom aluminum precision casting and aluminum investment casting parts. Other castable materials can also be reviewed according to project requirements.

Can you provide machining after investment casting?

Yes. CNC machining, drilling, tapping, polishing, deburring, heat treatment, and surface finishing can be arranged according to your drawing requirements.

Can you make samples before batch production?

Yes. For many custom precision casting projects, sample parts can be arranged before batch production for dimensional and surface confirmation.

What information should I send for quotation?

Please send your drawing, 3D file, or sample photos, together with material, quantity, tolerance, machining, surface finish, and application requirements.
