Fineblanking is a metal forming technique that produces precise and complex parts for various industries, including automotive, industrial, and original equipment manufacturers (OEMs). These services offer a cost-effective solution to manufacturing superior-quality components with tight tolerances and intricate designs.

This process also offers several advantages over other metalworking methods, such as stamping, laser cutting, and water jet cutting. This leads to less material waste and produces less scrap than other methods.

This article will discuss the process of fineblanking and its applications in automotive, industrial, and OEM companies.

The Fineblanking Process

Heres the step-by-step process for fineblanking:

Step 1: Material Preparation

The material used for fineblanking is typically a sheet metal coil cut to the desired width and length. The thickness of it can range from 0.5 mm to 12 mm, depending on the application. Afterward, the material is fed through a straightener to remove any distortions or deformations that may have occurred during the coil-making process.

Step 2: Blanking

Blanking is cutting the material to the desired shape and size. The blanking process uses a fineblanking press with three main components: the punch, the die, and the stripper.

Step 3: Piercing

Piercing uses a punch and a die, similar to the blanking process. However, the punch is typically smaller than the blanking punch and is used to create the desired holes or shapes in the component.

Step 4: Coining

This step is done using a punch and a die designed to apply high pressure to the components surface. The coining process improves the flatness and surface finish of the component.

Step 5: Finishing

Finishing involves removing any burrs or sharp edges that may have been left on the component during the blanking, piercing, or coining process. This step uses various finishing techniques, such as deburring, grinding, or polishing.

Automotive Industry

Fineblanking can produce high volumes of parts quickly and efficiently, making it a cost-saving option for automotive manufacturers. Engine components such as connecting rods, rocker arms, valve lifters, and timing gears are some critical parts produced using fineblanking. It is also ideal for creating gears, brakes, and fuel system components. These parts require high accuracy and precision to perform optimally in the engine.

Industrial Solutions

Fineblanking is widely used in industrial applications such as construction equipment, power tools, and appliances. One of its advantages is that it can produce parts with minimal distortion. Fineblanking can also have features with a smooth finish, which is important for some applications requiring a polished appearance.

The precision and repeatability of the process also reduce the need for secondary operations, further reducing production costs. These benefits make fineblanking an attractive option for industrial companies looking to produce high-quality parts at an affordable price.

OEM Sector

OEMs in various industries — such as aerospace, defense, and medical — rely on fineblanking to produce top-quality parts. These parts are often required to perform optimally in demanding environments. This process can also produce parts with minimal burrs. This makes it suitable for applications where precision and surface quality are crucial.

Some of the applications of fineblanking in the OEM sector include making components for hydraulic systems, surgical instruments, and firearm parts.
