メタルベンディングとは メタルベンディング
Metal bending is a fabrication process of sheet metal whereby metal is manipulated by pressurizing it to reach the desired angles and shapes. The process plays a critical role in the manufacturing of robust and durable components that are correctly shaped and applied to various industries including aerospace, automotive, medical and industrial production.
In Lewei Precision, we do metal bending with simple and complex design with sophisticated CNC press brakes. Our bent metal is always accurate in its bends, has tight tolerances, and is dependable in quality to use in prototypes; it can also be used in full scale.
メタルベンディングの仕組み
金属曲げ加工は、金属加工において重要な手法であり、通常はプレスブレーキまたは同様の機械を使用して、力を加えることによって金属を所望の形状に変形させます。この工程では、直線に沿って正確に成形し、シートメタルのV字、U字、チャンネル曲げなどの形状を作ることができます。この技術には、手動の方法から、精度と再現性を高めた高度なCNC（コンピューター数値制御）システムまである。
この金属曲げ技術は、丈夫で機能的な部品を効率的に製造するために広く使われています。小さなブラケットから大きな建築物まで、さまざまな部品の製造に一般的に使用されています。CNC技術の進化により、複雑で高精度な曲げ加工がより実現しやすくなり、設計の柔軟性と生産サイクルの短縮が可能になりました。CNCシステムは大量生産に特に有益で、ばらつきを最小限に抑え、大量ロットでも一貫した品質を保証します。

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
私たちの 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.
認定された品質管理とテスト
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.

CNC加工に関するFAQ
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.
