The feeding method of die casting is the “starting line” of the entire production process—it directly determines production efficiency, product quality, and the scope of applicable materials. Choosing the wrong feeding method can lead to 30% higher defect rates (e.g., porosity from unstable metal supply) or 50% lower production efficiency (e.g., manual feeding delays). But […]
A die casting factory is a specialized manufacturing hub that transforms molten metals into high-precision, complex parts using high-pressure molding technology. Unlike general machining shops, it focuses exclusively on the pressure casting process—turning liquid aluminum, zinc, or magnesium alloys into components that power industries from automotive to medical devices. But what exactly happens inside a
Die casting defects—from surface blemishes to internal cracks—cost manufacturers an average of 5–12% of annual production value (industry data). These flaws not only force rework or scrapping but also compromise part performance, especially for safety-critical components like automotive sensors or aerospace brackets. While processes like hot chamber die casting (for low-melting alloys) or cold chamber
Hot chamber die casting is a high-pressure metal-forming process designed for low-melting-point alloys—known for its speed, compact equipment, and consistent part quality. Unlike cold chamber die casting (which uses separate furnaces to feed molten metal), its injection chamber and punch are permanently immersed in molten metal, creating a closed, efficient workflow. This design makes it
The cost of aluminum alloy die casting per kilogram is not a fixed figure—it ranges from as low as ¥1.5/kg for simple standard parts to over ¥120/kg for highly complex precision components. This 80-fold difference stems from a mix of technical, production, and demand-related factors. For manufacturers and buyers alike, understanding what drives these costs
Integrated die casting is a revolutionary manufacturing technology that uses high pressure to inject molten metals (primarily aluminum alloys) into oversized, complex molds—producing fully integrated structural parts in one step. Unlike traditional processes that weld 50–100+ separate stamped components into a single structure (e.g., an automotive rear floor), integrated die casting eliminates assembly entirely. For
Low-pressure die casting and gravity die casting are two foundational metal-forming processes, each built on distinct mechanical principles. While both shape molten metal into finished parts using molds, their approaches to filling cavities—one driven by controlled pressure, the other by natural gravity—create stark differences in quality, efficiency, and cost. For manufacturers, choosing between them means
Die casting processing cost refers to the total expense of manufacturing die cast parts, covering material procurement, equipment operation, mold use, labor, and post-processing. It varies widely—for example, aluminum alloy parts processed by a 200-ton machine may cost ~\(0.45/kg, while complex copper alloy parts with high-precision requirements can exceed \)5/kg. This huge gap stems from
Die casting multi-material defects refer to uneven material distribution, foreign matter inclusions, or structural inconsistencies in die cast parts—often appearing as mottled surfaces, flake residues, or localized excess material. These defects not only ruin product aesthetics but also reduce mechanical strength by 15–20% (industry data) and increase scrap rates to 8–12% for high-precision parts. Unlike
Die casting flow marks are common surface defects in die casting production—characterized by linear grooves, color difference bands, or uneven texture along the metal flow direction. They typically appear in deep cavities, thin-walled areas, or near gating systems, reducing product aesthetics and even weakening structural strength. For manufacturers, flow marks lead to rework rates of
Cast aluminum prototypes are metal prototypes crafted from aluminum alloys via casting processes—such as die casting, gravity casting, or low-pressure casting. They bridge the gap between product design and mass production by replicating the final product’s structure, material properties, and surface finish, making them ideal for validating strength, assembly logic, and small-batch functionality.

Semi-solid die casting and ordinary die casting are two core technologies in metal forming, each optimized for different production needs. While both inject metal into molds to create parts, their fundamental differences in metal state, process control, and performance make them suited for distinct applications—from high-strength automotive components to low-cost consumer goods. But what exactly
Die-casting sand holes—also called porosity or pinholes—are tiny voids in die-cast parts, ranging from 0.1mm to 2mm in diameter. They appear as surface pinpricks, subcutaneous cavities, or internal pores, and can reduce a part’s tensile strength by 15–30% (industry data). For critical parts like automotive engine brackets or medical device components, sand holes even lead
Metal die casting prototype parts are the backbone of product development—they let teams test designs, validate functionality, and iterate fast before mass production. But with so many material options (aluminum, magnesium, zinc), casting processes (HPDC, vacuum-assisted), and design rules to follow, it’s easy to feel overwhelmed. How to choose the right approach for your prototype?
Aluminum alloy die-casting prototypes are the backbone of product development—they let teams test designs, validate functions, and fix flaws before mass production. But prototype projects often face tight deadlines and small budgets, making speed and cost-effectiveness critical. How to create high-quality aluminum die-casting prototypes without sacrificing efficiency? This guide breaks down the entire process, from
Aluminum alloy die casting machining parts are everywhere—from automotive components to electronic housings—thanks to aluminum’s lightweight, high strength, and cost-effectiveness. But turning molten aluminum into high-precision machined parts requires mastering every step: from choosing the right alloy to final surface treatment. How to avoid common pitfalls like porosity, distortion, or dimensional errors? This guide breaks
