What is Die Casting & Precise Casting?
Die casting is a high-pressure metal casting process that forces molten metal into a steel mold cavity under high pressure. The metal solidifies quickly, and the finished part is ejected from the die.
Die casting produces high-volume metal parts with excellent dimensional accuracy, smooth surfaces, thin walls, and complex geometries at low cost per part.
Today, die casting remains one of the fastest bulk production processes for precision non-ferrous metal components.
Precision Casting is also known as Investment Casting or Lost Wax Casting, which uses a wax pattern with a disposable ceramic shell to create complex, high-accuracy parts from almost any metal. Suit for small to medium batch metal parts.
What’s advantages of Die Casting & Precise Casting?
Consistent Quality & High Repeatability
Tooling produces identical parts every cycle， part #1 and part #1,000,000 are nearly the same. This minimizes scrap, reduces rejects, and ensures reliable quality for high-volume production.
Very High Production Speed
Tooling enables extremely fast cycle times: injection molding in seconds, Without tooling, each part would take hours (machining, manual fabrication).
Low Cost when High Volume
High upfront tooling cost is spread across tens of thousands to millions of parts. The more you produce, the cheaper each part becomes pennies at very high volume.
Minimal Material Waste
Tooling-based processes (injection molding, die casting, stamping) achieve 85–99% material utilization, far better than CNC machining. Less scrap means lower material cost plus better sustainability.
Complex Geometries & Fine Details
Tooling produces intricate shapes, thin walls, undercuts, threads, and surface textures that would be impossible or extremely expensive to machine individually. All features are built into the mold or die.
Automated Operation & Wide Material Range
It works seamlessly with robotic part handling and inspection systems, reducing labor costs and enabling lights-out manufacturing. Material versatility, works with both plastic and metal, even composite materials.

FAQs About Our Die Casting & Precise Casting Services
Why precise die casting?
Precision die casting is chosen when you need high-volume metal parts with tight tolerances, complex geometries, thin walls, and excellent surface finish — all with minimal secondary machining.
What is the typical dimensional tolerance for precision casting parts?
Precision casting achieves ±0.1–0.3 mm tolerances, while secondary CNC machining can tighten critical features down to ±0.01 mm.
Do you support export mold or production?
Yes, exactly. We support both. You can either for use at your own facility or leave it with us for long-term molding production.
What is your quality control system?
We operate under a rigorous Quality Management System (QMS) aligned with ISO standards. Our 5 Steps QC process is including IQC (Incoming Quality Control) , FQC (Final Quality Control) , OQC (Outgoing Quality Control) for routine production.
QE (Quality Engineering) / CAPA (Corrective and Preventive Actions) implemented throughout the entire product lifecycle, especially during the post-sale stage, to drive continuous improvement. Simply speaking 100% inspection before shipment to ensure zero defects.
What kind of quality assurance or warranty do you offer on orders?
One of the reasons engineers purchase from RPD is that we take on all the risks for you. We guarantee you’ll love what you get. Not happy with it? We’ll either redo it or give you a full refund. Your purchase is completely risk-free.
What is the typical lead time for a precision casting order?
Initial orders, including tooling development, typically take 4–6 weeks. Once the mold is completed, repeat orders usually require 2–3 weeks, depending on part complexity and quantity.
Which kind of file formats can I send for die casting & production?
We accept STEP, IGES, STL, DWG, DXF, and other common CAD formats.
What Factors will Influence Tooling Design?
1. Part Geometry – Shape, size, and complexity drive mold design. Thin walls, intricate details, and complex geometries require specialized features like additional cooling or advanced gating systems.
2. Material Selection – The plastic type affects cooling rates, shrinkage, and flow. Polypropylene shrinks more; polycarbonate needs higher mold temperatures. Abrasive or corrosive plastics also demand wear-resistant mold materials.
3. Tolerances & Precision – High-precision parts (automotive, medical) require tighter mold tolerances — which complicates design and increases cost.
4. Ejection System – Ejector pins, air blasts, or stripper plates must be carefully integrated to remove parts without damage — affecting both design and cycle time.
5. Gate Design – Gate type and location (direct, pin, edge) control how molten plastic enters the mold, impacting part quality, surface finish, and cycle time.
6. Undercuts & Parting Lines – Undercuts or complex shapes may require side actions or lifters to release the part, increasing mold complexity and cost.
Can we store the mold at your facility for future production orders? Do you provide free maintenance for the mold?
Yes, we offer two key benefits for molds set up at our facility: free storage and free maintenance.
