Detailed Product Overview

Brass Sheet Metal Blanking and Piercing

Brass sheet and strip is fed through progressive dies and single-station tools to blank component outlines and pierce mounting holes, slots and cut-outs in a single pass. Blanking tolerance is held to +/-0.05mm on outer profile, while piercing operations maintain +/-0.03mm positional accuracy for bolt holes, screw bosses and connector openings. High-speed presses process thin gauge brass (0.3mm to 1.5mm) for volume production, while heavier presses up to 200 tons handle brass plate up to 6mm for structural brackets and enclosure panels.

Brass Deep Drawn Sheet Metal Components

Deep drawing converts flat brass blanks into hollow, cup-shaped or box-section components such as connector shells, battery contact cups, and enclosure housings. Draw ratios up to 2:1 are achieved in a single draw, with multi-stage progressive drawing extending this to 5:1 for deeper components. Intermediate annealing is applied between draw stages to relieve work hardening in cartridge brass and yellow brass, maintaining wall-thickness uniformity across the drawn section.

Brass Bending, Forming and Multi-Bend Brackets

Flat brass blanks are bent and formed into brackets, mounting plates, and chassis components with multiple bend lines in a single forming operation. CNC press brakes and progressive-die forming stations produce bend angles from 0 to 180 degrees with springback compensation built into the tooling. Minimum bend radius is maintained at one times material thickness for annealed brass to avoid surface cracking at the bend line.

Brass Enclosure and Junction Box Components

Pressed brass panels, covers, gland plates and mounting brackets are manufactured for electrical enclosures and junction boxes where corrosion resistance and mechanical strength are required. Components are punched with standard cable entry hole patterns and knockouts matching common enclosure sizes, and are supplied with matching gaskets and fasteners on request.

Brass Terminal and Connector Housings

Deep-drawn and formed brass housings for terminal blocks, connector shells and battery terminals are produced with internal spring-contact features and external mounting flanges pressed in the same operation. Wall thickness and flange flatness are controlled to ensure reliable mating with matching connector components on the customer assembly line.

Brass Spring Clips and Retaining Components

Thin-gauge half-hard and hard-temper brass is used to press spring clips, retaining clips and grounding clips that rely on the springback characteristics of the material for clamping force. These components are produced on progressive dies with in-die forming stations that set the spring geometry to a repeatable force specification across production lots.

Brass Decorative and Architectural Pressed Sheet Parts

Brass sheet is pressed and embossed into decorative plates, name plates, hinges and architectural hardware components where surface appearance is as important as dimensional accuracy. Coining and embossing operations produce raised lettering, logos and textured surfaces, followed by polishing or lacquering to protect the finished appearance.

Surface Finished Brass Sheet Metal Components

Pressed brass components are supplied bare with anti-tarnish treatment, or finished with nickel plating, tin plating, chrome plating or clear lacquer coating depending on the corrosion resistance and appearance requirements of the application. Plating is applied after forming to ensure uniform coverage over bend radii, drawn walls and punched edges.

Key Features of Pressed Brass Sheet Metal Components

Material Grades and Formability

Brass alloy selection balances formability against strength and corrosion resistance. CZ108 (CuZn37) offers the best deep-drawing formability for complex shapes, while C26000 cartridge brass provides higher strength for structural brackets. Temper is specified from soft annealed for maximum formability to half-hard and hard for components that must retain spring force or resist deformation in service.

Dimensional Tolerances and Precision

Progressive die tooling and CNC press control maintain blanked profile tolerance of +/-0.05mm and hole position tolerance of +/-0.03mm across production runs. Flatness and formed-angle accuracy are verified using go/no-go fixtures and CMM inspection for components with critical mating dimensions.

Surface Finish Options

Surface finish is matched to the operating environment and appearance requirement. Nickel plating provides a bright, corrosion-resistant finish for visible hardware. Tin plating is applied where solderability or low contact resistance is required. Lacquer coating preserves the natural brass appearance while preventing tarnish for decorative and architectural components.

Corrosion Resistance

Brass alloys with copper content above 62% resist dezincification in most atmospheric and mild chemical environments. Where dezincification-resistant performance is required in water-contact applications, DZR brass grades are used in place of standard CuZn alloys, with composition verified by spectrometric testing on incoming material.

Mechanical Properties and Temper

Tensile strength of pressed brass components ranges from 320 MPa in soft annealed condition to over 550 MPa in hard temper, selected according to the forming and in-service load requirements of each component. Temper is verified by hardness testing on sample components from each production batch.

Custom Tooling and Prototyping

New brass sheet metal components are developed through CNC-cut prototype tooling for design validation before committing to hardened progressive-die production tooling. This allows dimensional and functional verification of brackets, housings and clips prior to volume production, reducing the risk of tooling rework.
