Die Casting vs. Injection Molding: Key Differences
Die casting and injection molding may both appear, at first glance, to involve "injecting molten material into a mold and then cooling it to form a part," but one uses metal at 700°C, while the other uses plastic at 200–300°C. This single difference in material sets off a domino effect, driving the mold design, pressure, precision, cost, and intended applications in entirely different directions. This article breaks down the key differences between the two into quantifiable dimensions, helping you instantly determine which process is right for your part.

What is precision machining for 3D-printed molds?
"The phrase "3D-printed molds" can easily lead people to believe that once printing is complete, the parts are ready for immediate production. However, actual industry practice is quite the opposite: virtually none of the inserts and cores produced through metal additive manufacturing are delivered without undergoing precision machining. So-called "precision machining for 3D-printed molds" simply refers to the use of subtractive methods—such as CNC milling, grinding, electrical discharge machining (EDM), and polishing—to refine printed parts from "raw material grade" to "mold grade.” This article thoroughly explains the principles behind this process, why it is necessary, which surfaces require machining, and the required tolerance levels.

Surface Roughness Chart: A Comprehensive Conversion and Process Comparison Guide for Ra, Rz, and RMS
Surface roughness is a symbol found in the lower-right corner of every drawing—Ra 0.8, Ra 3.2, ▽▽▽… But behind the same set of numbers, different machining processes can result in a difference of an order of magnitude. This article clearly explains the definitions of surface roughness parameters, conversion relationships, grade comparison tables, and process ranges all at once. In particular, it explains why the as-cast surface of die-cast parts can be used directly without secondary machining, helping you avoid making guesses during design, quoting, and acceptance.

Die Casting Process Guide: A Comprehensive Analysis of Principles, Materials, Molds, and Plant Selection
Die casting is currently one of the most efficient processes for mass-producing precision metal parts. From a front-line factory perspective, this article systematically explains the principles of die casting, the two main types (hot-chamber and cold-chamber), how to select material grades, common pitfalls to avoid in mold design, and—most importantly—how to assess a die-casting factory’s technical proficiency. Whether you’re a structural engineer, a procurement specialist, or a project manager, reading this will help you avoid unnecessary detours.

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.
