Custom Progressive Stamping Die for Washing Machine Metal Parts

Progressive die for washing machine feet (progressive stamping die), specifically designed for high-speed automated mass production of washing machine metal bases/support feet/fixed brackets (SPCC cold-rolled sheet, galvanized sheet, stainless steel, material thickness 0.5–1.2mm). It completes punching, bending, stretching, and blanking in a single stroke, suitable for production capacities of millions, and is a core die for mass production of sheet metal for home appliances.

Product Material: Mainly cold-rolled steel sheet/stainless steel/galvanized sheet stamping parts

Die Material: DC53 or SKD11

Application Scenarios: Mass standardized production of washing machines (monthly output ≥ 50,000 sets)

Metal Feet/Brackets: Complex sheet metal parts with multiple holes, bends, flip-holes, and reinforcing ribs

Requirements: Home appliance base accessories requiring stable load-bearing capacity, high assembly precision, and rust resistance

Not Suitable for: Small batches, multiple varieties, ultra-deep drawing, single-piece customization

Product Advantages: High Efficiency: Continuous stamping (SPM 40–60 times/minute), single die daily output can reach several thousand pieces, far exceeding single-process dies

High Precision Consistency: Continuous positioning + One-piece molding, dimensional tolerance ±0.05mm, flatness ≤0.1mm, suitable for standardized mass production.

Automation: Automatic feeding of coiled material → stamping → blanking → collection, less manual labor, safe, suitable for unmanned production lines.

Low cost: Reduced processes, equipment, and semi-finished product turnover, significantly reducing unit cost.

Surface treatment: Commonly used electroplating blue-white zinc, powder coating, or direct use of galvanized sheet (80g) to reduce costs.

Common process problems in factory production:

1. How to control springback? High springback during bending of stainless steel/cold-rolled sheet; pre-compensation angle in the mold + shaping step.

2. How to handle scrap? Optimize scrap cutter angle, add air blowing/suction device.

3. How to prevent cracking during hole turning? Precise pre-punching size, R-angle transition, step-by-step hole turning to avoid stress concentration, TD treatment of punch.

4. How to reduce maintenance time? Quick replacement of easily worn punching/bending inserts to reduce maintenance downtime.
