金属弯曲的工作原理是什么？
金属弯曲是金属加工中的一种重要方法，通常使用压力制动器或类似机器，通过施力将金属变形为所需形状。这种工艺可以沿直线精确成型，在金属板上形成 V 形、U 形或槽形弯曲等形状。该技术的范围从手工方法到先进的 CNC（计算机数控）系统，后者可提供更高的精度和可重复性。
这种金属弯曲技术被广泛用于高效生产坚固的功能部件。它通常用于制造从小型支架到大型建筑特征的各种部件。随着数控技术的发展，复杂和高精度的折弯任务现在变得更加可行，提供了更大的设计灵活性和更快的生产周期。数控系统尤其适用于批量生产，可将差异降至最低，并确保大批量生产的质量始终如一。

Surface Finishes for Metal Bending Services
We can offer our customers bending of metal and various finishes on the post-bending surface to make it durable, resistant to corrosion, and appealing. The use of these finishes is done following bending so that the functional and aesthetic needs of the industrial and commercial uses of the bent metal parts are satisfied.
Durable, high-performance finish that prevents corrosion in bent metal components and maintains consistent color and surface coverage, suitable to exteriors and high usage.
Provides a smooth, matte finish that enhances the adhesion of coating and offers a uniform, professional polish on bent metal surfaces.
A type of electrochemical finish, which enhances corrosion resistance and surface hardness, and also provides decorative colors to aluminum bent items.
Creates a uniform, linear texture that enhances appearance and minimizes visible scratches on cosmetic and visible metal components.
Gives the appearance of a smooth mirror-like surface finish, usually on decorative, consumer-facing or high-visibility bent metal components.
Applies a thin metal layer such as nickel or zinc to improve corrosion resistance, wear performance, and electrical conductivity of bent metal parts.
Metal Bending Services for Diverse Industries
我们的 metal bending services support a wide range of industries that demand precision, strength, and consistency. From tight-tolerance components to complex bent geometries, we deliver custom metal bending solutions tailored to each industry’s functional and performance requirements.
经认证的质量控制和测试
In our metal bending services, quality control is a very strict process that involves all the bent metal parts to fit precisely to the dimension and functionality specifications. The individual components are checked with calibrated instruments and coordinate measuring machines (CMM) to ensure the accuracy of the bend angles, size and accuracy of the whole component. This guarantees quality in a prototype and production run even in a tight-tolerance application.
Bent metal components are all checked against GD&T specifications and also ISO and ASME standards to ensure that they meet design specifications. In case of projects that need surface finishes, further testing is used to evaluate the coating thickness, adhesion, and appearance which will ensure durability and similar quality of finish when bending.
We are fully traceable by offering full documentation with material certificates, inspection reports and quality records. This open practice helps customers to trust in the quality, consistency and certified quality of our metal bending services.

数控加工常见问题
What metal bending services are available at Lewei Precision?
We offer press brake bending, roll bending, tube bending, and custom forming for sheet metal and tubing. Our press brakes handle widths up to 4 meters and tonnage up to 400 tons, suitable for thick steel plate and complex multi-bend parts.
What is the minimum bend radius Lewei can achieve?
Minimum bend radius depends on material and thickness. As a rule, we maintain a bend radius equal to or greater than the material thickness. For aluminum, the bend radius is typically 1.5× thickness to prevent cracking. Our DFM team confirms feasibility before quoting.
What metals can Lewei Precision bend on press brakes?
We bend cold-rolled steel, hot-rolled steel, stainless steel 304 and 316, aluminum 5052 and 6061, galvanized steel, copper, and brass. Sheet thickness ranges from 0.5mm to 10mm depending on the alloy and required bend angle.
How accurate are bend angles on Lewei’s press brakes?
Our CNC-controlled press brakes hold bend angle tolerance of ±0.5° and bend length tolerance of ±0.2mm. For tighter tolerance requirements, we use angle-measuring sensors and post-bend inspection.
Do you handle short-run and high-volume metal bending orders?
Yes. From single prototypes to production runs of 50,000+ parts per year, our press brakes are programmed quickly using offline software, keeping setup costs low even for short runs.
Can Lewei Precision combine laser cutting and metal bending in the same project?
Yes. Our integrated workflow takes parts directly from laser cutting through bending, welding, and finishing under one roof. This reduces lead time, eliminates shipping between vendors, and ensures consistent quality.
