500 Ton Four Pillar Hydraulic Press Machine
The 500-ton four-column hydraulic press is the industry-standard manufacturing solution engineered for high-volume stainless steel basin and sink production. When paired with high-performance stretching dies and proper lubrication, it delivers consistent deep-profile shapes, low defect rates, and excellent surface finish preservation.
Use Case
Manufacturing stainless steel basins requires large-deformation drawing capable of shaping deep cavities without tearing or micro-cracking the metal. The system protects pre-polished mirror or satin sheet surfaces while stretching tough alloys into single or multi-bowl kitchen and commercial catering profiles.
Core Applications: Deep drawing, large-deformation metal stretching, multi-stage basin drawing, flange trimming, and edge coining of sanitary ware.
Material: Austenitic stainless steel sheets including grades SS304, SS201, and SS316, with material thicknesses spanning from 0.6 mm to 2.5 mm.
Typical Products Formed: Single and double-bowl residential kitchen sinks, commercial catering wash basins, industrial utility sinks, and medical-grade laboratory washbasins.
Key Functions: Supplies high-tonnage downward drawing forces, delivers independent hydraulic cushion blank-holder pressures to control material flow, and executes deep-cavity shaping without tearing thin walls.
Why 500-Ton Hydraulic Press?: It provides the massive force required to overcome the extreme work-hardening tendencies of stainless steel, utilizing rigid four-pillar guidance to prevent asymmetric tool wear during deep draws.

05 — Key Advantages
Why Choose the 500-Ton Sinter Hydraulic Press
The 500-Ton Sinter Hydraulic Press delivers the immense tonnage and stable frame rigidity needed to overcome the extreme work-hardening resistance of stainless steel. It combines variable velocity drawing profiles with high commercial throughput to deliver premium, crack-free sanitary basins at a optimized cost per unit.
Massive Tonnage to Overcome Tough Work Hardening
The 500-ton hydraulic force effortlessly drives deep deformation into structural stainless steel sheets without stalling or slowing mid-stroke. This ensures complete molecular stretching through the tightest corner radii, completely eliminating splitting defects in demanding alloys.
Proportional Cushion Control to Stop Flange Wrinkling
An advanced multi-point hydraulic die cushion dynamically adjusts blank-holder pressure across the sheet metal surface during the cycle. This precise material flow restriction prevents heavy flange wrinkling while safely drawing material into deep-dished sink profiles.
Four-Pillar Guiding for Flawless Surface Integrity
The heavy-duty four-column layout maintains absolute structural parallelism between the upper punch and lower die block under high pressure. This balanced guidance prevents asymmetric slide tilting, preserving expensive pre-polished mirror or satin sheet finishes from friction scratches.
Programmable Speed Profiling to Prevent Micro Cracks
The intelligent control valves slow down the ram velocity precisely as it approaches the maximum material stretch zone. This controlled deceleration allows the stainless steel matrix to flow naturally, preventing localized wall thinning and invisible micro-fracturing.
Exceptional Repeatability for Strict Quality Benchmarks
The integrated programmable logic controller system stores exact pressure, stroke, and dwell parameters for distinct sink bowl geometries. This digital tracking guarantees consistent wall thickness distribution and identical dimensional output across massive production runs.
Minimized Material Scrap for Maximized Profit Margins
Eliminating deep drawing defects like tearing, scoring, and puckering dramatically cuts down the rejection rate of expensive raw metal. This high-yield forming cycle directly reduces commercial scrap costs, maximizing operational profitability for tier-one manufacturers.
