The process of pouring molten metal into a mold cavity tailored to the shape and size of the part, allowing it to cool and solidify to obtain a blank or part, is commonly known as liquid metal forming or casting.

CNC (Computer Numerical Control) machining has become an essential technology in today’s competitive manufacturing world. From automobile engine components to smartphone metal frames and aircraft-grade titanium parts, many of the highest-precision products rely on CNC tools to take shape. Yet for the general public, how CNC tools actually work—how a block of metal transforms into a finely shaped part—remains a mystery.

Commonly used steel grades and performance characteristics.

Welding, as a core process in metal processing, directly determines the safety, durability, and aesthetics of a product based on weld quality. The core requirements for post-weld grinding include ensuring a smooth and flat weld surface, removing weld slag and defects, controlling the amount of base material removed to no more than 5% or 0.2mm, ensuring the grinding pattern is consistent with the weld direction, and adjusting the specific operation according to the welding type (e.g., aluminothermic welding) and material (e.g., stainless steel).

This article introduces 12 effective methods for preventing rust and corrosion in metal tools and machinery. Techniques include using stainless steel, coatings, cathodic protection, bluing, galvanized or weathering steel, proper storage, regular maintenance, VCI packaging, and more. Applying these strategies extends equipment life, maintains performance, and reduces costly repairs.

This article explains residual stress and six common methods for its elimination in industrial components. Techniques include hammering, vibration aging, heat treatment, natural aging, welding stress relief, and machining-based surface strengthening. These methods help reduce residual stress peaks, balance stress distribution, and improve part stability and service life, making them crucial for high-precision or high-value components.

This article outlines seven effective machining strategies to prevent deformation in aluminum alloy parts. From symmetrical cutting, layer-by-layer milling, proper cutting parameters, optimized tool geometry, and secondary clamping to drilling before milling, each method helps improve stability, reduce heat accumulation, and enhance overall machining precision. These techniques are especially valuable for thin-wall or high-precision aluminum components.

Chamfering is a term in mechanical engineering. To remove burrs produced during machining and to facilitate assembly, chamfers are typically made at the ends of parts.

In modern machinery manufacturing, aerospace, automotive, and hydraulic industries, pipe fittings serve as key components for load bearing, flow guidance, and connection, and their processing technology directly affects the performance and reliability of equipment. With the continuous development of materials science and manufacturing technology, pipe fitting processing has formed a diversified and precise process system, from traditional turning to spinning, stretching, powder metallurgy, and sheet metal welding, each method having unique advantages and applicable scenarios.

In 2025, the sheet metal processing industry will focus on process upgrades, intelligent manufacturing, and supply chain restructuring: breaking through precision and efficiency bottlenecks through technological iteration, adapting to flexible production needs through digital transformation, exploring new domestic and international markets through global industrial adjustments, and empowering the upgrading of high-end manufacturing industries.
