Find answers to common questions about RuiYu’s custom die casting services, materials, tooling, manufacturing processes, quality control, and OEM cooperation.
RuiYu provides custom aluminum and zinc die casting solutions for various applications, including automotive components, motor parts, lighting housings, hardware components, and other OEM metal parts.
We support complete manufacturing services from product development and tooling to die casting, CNC machining, surface finishing, and final inspection based on customer requirements.
Yes. We support OEM projects based on 2D drawings, 3D CAD files, or physical samples.
Our engineering team will review the part design, material requirements, wall thickness, draft angles, and production feasibility through DFM analysis before tooling development.
To prepare an accurate quotation, please provide:
If drawings are unavailable, we can also evaluate samples or product concepts.
We mainly provide aluminum and zinc die casting solutions.
Common aluminum alloys include ADC12 and A380, which are widely used for structural parts, housings, and industrial components.
Zinc alloys (Zamak) are commonly used for hardware, locks, handles, and decorative components requiring excellent surface quality and dimensional accuracy.
The material selection depends on product requirements.
Aluminum die casting is suitable when lightweight, strength, and heat dissipation are important.
Zinc die casting is ideal for complex shapes, high dimensional accuracy, and premium surface finishes such as electroplating.
Our engineering team can recommend the most suitable material based on application requirements.
We provide various surface treatment solutions for aluminum and zinc die-cast parts, including:
These finishing processes improve corrosion resistance, durability, and appearance quality for different applications.
Yes. We provide complete tooling support including mold design, DFM analysis, tool manufacturing, trial production, and sample validation.
Our engineering experience helps optimize mold structure, casting performance, and production stability.
Tooling lead time typically depends on part complexity, cavity number, and surface requirements.
For standard projects, mold development usually takes approximately 30–45 days, including design, manufacturing, and trial samples.
Yes. We support prototype validation, trial production, and small-to-medium batch manufacturing.
This allows customers to verify product design, assembly requirements, and quality before full-scale production.
For custom die casting projects, tooling costs are usually quoted separately from production costs.
The tooling investment depends on part complexity, mold structure, cavity requirements, expected production volume, and material selection.
Before tooling starts, we provide a clear tooling quotation and production plan for customer review and approval.
For customer-funded tooling projects, the customer retains ownership of the molds.
RuiYu manages and maintains the tooling during production to ensure stable manufacturing performance.
If required, tooling ownership details can be confirmed in the project agreement before production begins.
We control quality throughout the manufacturing process, including:
For critical components, CMM inspection and other testing methods can be provided according to customer requirements.
With over 20 years of die casting industry experience, RuiYu provides engineering support and reliable OEM manufacturing solutions for global customers.
We help customers reduce development risks, optimize production processes, and coordinate reliable supply chains from tooling to finished components.
