High-Precision Custom Deep Drawing Die for Electrical Housings

The High-Precision Custom Deep Drawing Die for Electrical Housings is engineered for the precision forming of metal enclosures, protective covers, electrical equipment housings, control box components, sensor housings, and other deep-drawn sheet metal parts.

Designed according to customer drawings, 3D CAD files, samples, and press-machine specifications, the tooling enables controlled material flow during the deep drawing process. This helps maintain consistent wall thickness, dimensional accuracy, corner radii, and overall structural integrity for electrical housing applications.

Technical specifications are project-dependent. Final die construction, tolerance, press capacity, material thickness, and tool-life requirements are confirmed during engineering review.

Electrical housings often require a combination of deep walls, small corner radii, mounting features, openings, flanges, embossed structures, and controlled dimensional relationships. Proper die design is therefore essential for stable production.

METS evaluates the following factors during tooling development:

The blank must flow smoothly into the die cavity during drawing. Excessive resistance can cause thinning or cracking, while insufficient control can result in wrinkles or dimensional instability.

For deeper electrical housings, multiple drawing operations can be used instead of forcing the entire depth in a single operation. Multi-stage drawing helps distribute deformation and improve forming stability.

The punch and die radii are optimized according to material type, thickness, housing geometry, and drawing depth to help reduce localized stress.

Appropriate blank-holder pressure helps control material flow and reduce wrinkling while avoiding excessive resistance that could cause material failure.

Proper clearance is important for dimensional accuracy, material flow, tool wear, and final surface quality.

Additional operations such as trimming, piercing, punching, embossing, bending, and flange forming can be incorporated into the tooling solution according to the electrical housing design.

METS is an integrated manufacturer combining die design, precision tooling manufacturing, stamping, deep drawing, and customized metal component production.

DC53 is suitable for demanding stamping and forming applications where improved wear resistance and toughness are required. It can be selected for electrical housing dies requiring stable dimensional performance during repeated production.

SKD11 and D2 are commonly used tool steels for stamping and forming applications. They are suitable for components requiring good wear resistance and dimensional stability.

High-speed tool steels such as SKH-9 and SKH-51 can be considered for high-wear areas or specific cutting and forming components.

Tungsten carbide materials such as YG15 and YG20 can be used for selected high-wear die components according to the forming and production requirements.

The final material selection is determined according to the workpiece material, geometry, production volume, forming load, wear conditions, and required tool life.

• Electrical Control Enclosures - Deep drawing dies can be used to manufacture compact metal housings for electrical control systems, switching components, control modules, and industrial electrical equipment.
• Power Supply Housings - Custom deep drawing tooling is suitable for forming protective metal shells and enclosures used in power supply and electronic equipment.
• Sensor Housings - Precision-drawn housings can provide a rigid metal structure for sensors and monitoring devices.
• Industrial Electronics - Suitable for housings used in automation systems, control equipment, testing instruments, and industrial electronic assemblies.
• Motor and Electrical Component Housings - Deep drawing can produce cylindrical or custom-shaped shells for motor-related components and electrical assemblies.
• Protective Metal Enclosures - The tooling can be customized for square, rectangular, cylindrical, stepped, and other protective enclosure structures.

METS has tooling experience in stainless steel box and sheet metal forming applications. A progressive deep drawing or forming die can integrate drawing, trimming, and piercing operations to produce a finished enclosure with consistent dimensions.

For lightweight electrical housings, aluminum can be processed through precision deep drawing and progressive tooling. The forming process can be optimized according to aluminum grade, thickness, drawing depth, corner radius, lubrication, and material flow requirements.

METS provides precision stamped and deep-drawn metal shells for sensor applications, with customizable openings, mounting features, and structural details.

METS' deep-drawing tooling can also be applied to cylindrical metal shells and housings. Multi-stage deep drawing is used when the required depth or geometry cannot be efficiently produced in a single drawing operation.

Electrical housings require more than simple sheet metal forming. The tooling must control material flow, dimensional accuracy, wall thickness, corner geometry, and secondary features throughout the forming process.

METS develops customized deep drawing dies around the actual production requirements of the electrical housing. From the initial CAD drawing, engineers can evaluate drawing depth, material thickness, material grade, drawing ratio, corner radius, punch and die clearance, blank-holder requirements, number of drawing stages, trimming requirements, piercing and punching features, press-machine specifications, production volume, and expected tool life.

A properly designed deep drawing die can reduce unnecessary secondary operations and improve production consistency. For electrical housing manufacturers, this can help achieve:

Stable Dimensions → Reliable Assembly → Consistent Forming → Reduced Production Variation
