small drawn parts & cans
Built for controlled depth, wall geometry, fit, and repeatable forming.
Gromax manufactures small drawn metal parts including cups, cans, shells, covers, housings, and enclosures produced through controlled drawing and forming operations.
We review material, thickness, draw depth, corner radii, wall geometry, flange condition, tolerances, finish, and downstream assembly requirements to support consistent production.
part examples
Drawn Cups
Cylindrical or shaped components formed from flat strip or blanks into cup-like geometries for containment, protection, spacing, or assembly functions.
Metal Cans
Small drawn enclosures used to surround, protect, shield, or contain electrical, electronic, sensor, or mechanical components.
Drawn Shells
Formed housings with controlled wall and bottom geometry used around internal components or subassemblies.
Protective Covers & Caps
Drawn or formed metal parts used to cover terminals, mechanisms, sensors, contacts, or other assembly features.
Sensor & Electronics Housings
Small drawn housings used to package or protect sensing elements, electronic components, or electromechanical features.
Flanged Drawn Parts
Cups or shells with retained flanges, rims, or formed edges used for mounting, locating, sealing, crimping, or joining to mating components.
Not sure where your part fits?
part design essentials
Reliable drawn-part performance depends on how material flow, geometry, tooling, and the final assembly work together.
Draw Depth & Diameter Relationship
Part depth, opening size, blank diameter, and material ductility influence whether the geometry can be produced in one draw or requires multiple drawing and redrawing stages.
Material & Temper
Ductility, strength, strain-hardening behavior, thickness consistency, and surface condition affect drawability, wall thinning, wrinkling, and cracking risk.
Corner & Bottom Radii
Punch and die radii influence material flow, local strain, wall transition, and the risk of tearing or excessive thinning.
Wall Thickness & Uniformity
Drawing changes material distribution, and some wall thinning or thickening can occur depending on geometry and process conditions, so critical wall requirements should be defined appropriately.
Flanges, Rims & Openings
Flange width, edge geometry, trimmed height, and opening dimensions affect forming stability, assembly fit, and later operations such as crimping or joining.
Surface Finish & Tooling Marks
Lubrication, tooling condition, material finish, and draw severity can affect scratches, galling, scoring, or cosmetic appearance on visible or functional surfaces.
from DfM to Production
Gromax supports small drawn-part programs from drawing review through repeatable production.
Part & DfM Review
Review the drawing, function, material, thickness, draw depth, radii, tolerances, finish, assembly method, and production volume.
Draw Tool Design & Build
Develop tooling for blanking, drawing, redrawing, ironing where appropriate, trimming, piercing, flanging, and related forming operations.
Precision Drawing & Forming
Establish a repeatable process around depth, diameter or profile, wall condition, flange geometry, concentricity where required, and final formed relationships.
Secondary Operations & Finishing
Incorporate trimming, piercing, deburring, cleaning, plating, coating, heat treatment where applicable, machining, or assembly into the production plan.
Production Support
Support ongoing programs with tool maintenance, dimensional review, process monitoring, root-cause analysis, and corrective action.
quality & assembly fit
Inspection should verify the characteristics that determine whether the drawn part fits, encloses, protects, or joins correctly in the finished assembly.
Overall Geometry
Outside dimensions, opening size, depth, height, profile, and overall formed condition.
Wall & Bottom Condition
Wall thickness where critical, wall straightness, bottom geometry, thinning, and local deformation.
Flanges & Rims
Flange width, rim condition, trimmed height, edge profile, and formed features used for mounting or joining.
Surface Condition
Scratches, galling, scoring, dents, burrs, plating or coating coverage, and cosmetic condition where specified.
Assembly Fit
Fit with internal components, mating housings, seals, fasteners, crimp features, or other interfaces in the final assembly.
Gromax checks critical dimensions using standard measurement, optical inspection, fixtures, custom gaging, or functional inspection methods and reviews your certification, traceability, and inspection documentation needs.
