Morire casting

Pressofusione per gravità (noto anche come fusione in stampo permanente) è un processo fondamentale di formatura dei metalli che si basa sulla forza naturale della gravità per riempire le cavità dello stampo con metallo fuso. A differenza della pressofusione ad alta pressione, evita complessi sistemi di pressione, making it a cost-effective and reliable choice for specific industrial scenarios—especially for thick-walled parts requiring heat treatment […]

La pressofusione in conchiglia di alluminio è un processo fondamentale nella produzione di materiali leggeri, custodie durevoli per l'elettronica, componenti automobilistici, e attrezzature industriali. A differenza delle parti in alluminio massiccio, i gusci in alluminio richiedono un controllo preciso sullo spessore delle pareti, finitura superficiale, e integrità strutturale: anche piccoli difetti come porosità o deformazione possono rendere il guscio inutilizzabile (PER ESEMPIO., compromising waterproofing for phone casings or

Versare (colata per gravità) and die casting are two foundational metal-forming processes, each optimized for distinct production needs. While pouring relies on the natural force of gravity to fill molds, die casting uses high pressure to inject molten metal at high speed—these core differences shape their performance, costo, and application scenarios. Per i produttori, choosing the wrong

Integrated die casting, a game-changing technology in manufacturing—especially for the automotive industry—redefines how complex components are produced. By merging dozens to hundreds of traditional stamped and welded parts into a single, seamless component via super-large die casting machines, it addresses long-standing pain points like low production efficiency, high assembly costs, and heavy part weights. Tuttavia,

Pressofusione assistita da gas (GADC) is a revolutionary advancement in metal forming that addresses key limitations of traditional die casting. By integrating high-pressure inert gas (typically nitrogen) into the casting process, it creates hollow structures or functional channels within parts—opening new possibilities for lightweight, complesso, and high-performance components. For manufacturers struggling with material waste, design constraints,

The minimum thinnest wall thickness of aluminum alloy die casting is a critical design parameter—too thin, and you risk defects like undercasting or cold barriers; troppo spesso, and you waste material and increase production time. While technical breakthroughs have pushed the limits of how thin aluminum die cast parts can be, Non esiste una risposta unica.

The die casting runner system is the “vascular network” of the die casting process—without a well-designed system, molten metal cannot flow smoothly into the mold cavity, leading to defects like cold shuts, porosità, o sottogetto. As the only channel connecting the injection device to the mold cavity, it directly impacts production efficiency, Qualità parziale, E

Die casting coils, a critical internal defect in the die casting process, severely undermines the mechanical performance and reliability of castings. Unlike surface flaws like scratches or burrs, this defect hides inside castings, often only detectable through non-destructive testing (such as X-rays). Its core is the entrainment of air or gas into the molten metal

The die casting injection process is a precisely orchestrated sequence of speed and pressure adjustments that transforms molten metal into high-quality parts. While it may seem like a single “injection” step, it actually unfolds in distinct stages—each designed to solve a specific challenge, from expelling air to preventing defects like shrinkage or flash. These stages

Die casting product sink—also called dent or shrinkage depression—is a prevalent surface defect characterized by smooth, sunken areas (0.1–2mm deep) that form in thick-walled sections of cast parts. It not only ruins product aesthetics (rejecting 5–8% of parts in mass production) but also weakens structural integrity: sinks in pressure-bearing components (PER ESEMPIO., valvole idrauliche) can cause

Shrinkage cracking is one of the most destructive defects in aluminum alloy die casting—manifesting as thin, linear cracks that often penetrate the entire part. Unlike surface blemishes (PER ESEMPIO., pockmarks) that affect aesthetics, shrinkage cracking directly compromises structural integrity: parts with such cracks may fail under load, comportando rischi per la sicurezza (PER ESEMPIO., automotive component failure) O

Semi-solid die casting (SSDC) is an advanced metal-forming technology that bridges the gap between traditional casting and forging—redefining how high-performance metal parts are made. A differenza della pressofusione convenzionale (which uses fully molten metal) o forgiando (which relies on solid metal deformation), SSDC leverages metal in a semi-solid state (50–90% solid fraction) to create parts with

La pressofusione di alluminio è ampiamente utilizzata nel settore automobilistico, elettronica, e industrie aerospaziali grazie alla sua leggerezza, alta resistenza, ed efficacia in termini di costi. Tuttavia, il processo coinvolge molteplici e complessi collegamenti, dalla selezione del materiale al post-trattamento, e qualsiasi svista può portare a difetti come la porosità, crepe, o sottogetto. Per garantire una produzione stabile e parti in alluminio di alta qualità, manufacturers must master critical precautions

Nella formatura dei metalli, la fusione di precisione e la pressofusione sono due processi fondamentali, ciascuno adattato alle distinte esigenze produttive. La fusione di precisione eccelle nella creazione di complessi, parti ad alte prestazioni in piccoli lotti, mentre la pressofusione domina la produzione di massa di prodotti leggeri, componenti a pareti sottili. Per i produttori, choosing the wrong process can lead to wasted costs, progetti ritardati, or subpar product

Die casting clip is a typical surface defect in the die casting process, which seriously affects the appearance quality and structural integrity of castings. It is mainly manifested as obvious delamination or peeling on the casting surface—these defects not only reduce the product’s market competitiveness but may also cause safety hazards in high-precision application scenarios

La pressofusione è un processo di produzione ampiamente utilizzato per produrre parti metalliche complesse con elevata precisione. Tuttavia, non è privo di sfide. Durante il processo possono verificarsi vari difetti, influendo sulla qualità, prestazione, e il costo dei prodotti finali. Understanding these common problems and their solutions is crucial for manufacturers to improve production efficiency and
