China's Top 10 Gravity Casting Factories in 2026 (Authoritative List and Factory Selection Guide)
Gravity casting (also known as metal mold casting or permanent mold casting) is one of the most essential forming processes for aluminum alloy components. In 2026, driven by the dual trends of lightweighting and integrated forming in the new energy vehicle sector, the concentration of China’s gravity casting industry continued to rise, with leading foundries accelerating their expansion into overseas markets by leveraging in-house mold manufacturing, comprehensive process capabilities, and one-stop delivery services. This article compiles an authentic list of China’s top ten gravity casting factories and provides practical criteria for evaluating them, helping procurement and engineering teams accurately identify suppliers.

A Comprehensive Guide to Die-Casting Mold Acceptance Standards: 9 Key Acceptance Criteria, from Mold Materials to Finished Product Inspection
Die-casting molds are the "gateway" to a product’s dimensional accuracy, surface quality, and production efficiency. A single oversight can result in an entire batch being scrapped. Based on actual factory acceptance checklists, this article comprehensively outlines nine major categories of mold acceptance criteria, along with finished product acceptance standards, mold price references, and maintenance schedules—all of which can be printed directly for on-site inspection.

How to Choose a Casting Process: Low-Pressure Casting vs. Gravity Casting vs. Die Casting vs. Sand Core Casting
Two castings with similar specifications on the drawings can differ by more than double in yield rate, cost, and service life simply because the wrong process was selected. As an engineer with many years of experience in aluminum alloy casting, I initially relied on experience to make decisions. It wasn’t until I broke down the three variables—wall thickness, performance requirements, and batch size—and compared them individually that I was able to base my process selection on a reproducible, logical framework.

How Is the Tonnage of a Die-Casting Machine Calculated? Formulas for Selecting Clamping Force and Projected Area + Examples
Many engineers ask the same question when initiating a die-casting project: How do you calculate the tonnage of a die-casting machine? If the tonnage is too low, the high pressure of the molten metal will force the parting line apart, resulting in flash and dimensional deviations; if you choose too large a machine, you’ll end up wasting equipment, molds, and energy. Essentially, selecting the right die-casting machine tonnage revolves around just two core parameters: clamping force and projected area. This article takes you step by step through the calculation process, from breaking down the parameters to practical case studies.
Quick Conclusion: Die-casting machine tonnage = injection pressure ratio × total projected area × safety factor. First, calculate the total projected area, look up the injection pressure ratio for the alloy, multiply it by the safety factor, and then round up to the nearest standard tonnage—this will ensure you select the correct machine on the first try.

China's Top 10 Low-Pressure Die-Casting Plants in 2026: A Review of Aluminum Alloy Low-Pressure Die-Casting Manufacturers' Capabilities
Driven by the dual trends of lightweighting in new energy vehicles and the upgrading of high-end equipment, low-pressure casting (LPC) has become the primary process for aluminum alloy castings—such as valve covers, steering knuckles, transmission housings, and battery enclosures—thanks to its advantages of smooth filling, low porosity, and excellent mechanical properties (tensile strength ≥300 MPa, capable of T6 heat treatment), has become the primary process for aluminum alloy castings such as valve covers, steering knuckles, transmission housings, and battery enclosures. So, which are the top ten low-pressure casting factories in China for 2026? What sets them apart in the market? This article breaks it down for you step by step and provides an in-depth analysis of Ningbo Hexin Molding, which excels in integrated mold and casting solutions.
