Why Choose the 800-Ton Sinter Hydraulic Press

The 800-Ton Sinter Hydraulic Press delivers the massive forming pressures and frame rigidity required to cold-upset tough titanium and nickel superalloys. Its micro-precise control systems guarantee absolute structural density and repeatable tolerances, fulfilling the zero-defect mandates of flight-certified production.

Technical & Commercial Benefits

01

Massive Tonnage Capacity to Form High-Strength Advanced Aerospace Alloys

The specialized fluid system generates intense compression forces capable of cold-working titanium and Inconel raw stocks. This high mechanical pressure induces deep strain-hardening to elevate the material yield and shear fatigue strength.

02

Pre-Stressed Four-Column Architecture Minimizing Die Mismatch and Deflection

An ultra-rigid guide assembly effectively absorbs heavy off-center loading stresses produced during multi-station extrusion sequences. Maintaining perfect platen parallelism prevents dimensional skewing and protects premium tungsten carbide inserts from micro-cracking.

03

Sub-Micron Electronic Stroke Limitation for Near-Net-Shape Repeatability

Dual non-contact linear transducers continuously track the down-stroke depth to achieve extreme dimensional control accuracy. Producing virtually perfect geometric blanks minimizes material machining requirements and eliminates subsequent weight balancing issues.

04

Multi-Stage Proportional Velocity Controls Eliminating Microstructural Flaws

The programmable logic control system throttles pressing speeds down to individual millimeters per second to control metal flow rates. Regulating the internal material displacement velocity prevents sudden friction cracks or surface galling defects from ruining batches.

05

Integrated Automatic Ejection System Facilitating Fast Cycle Throughput

High-speed hydraulic knockout rods automatically strip tightly compressed fastener pins from deep die pockets upon ram reversal. This seamless mechanical extraction allows direct handshakes with robotic transfer equipment to increase total hourly yields.

06

Drastic Reduction in Raw Material Scrap Maximizing Export Profit Margins

Cold forging components directly from continuous wire or pre-cut slugs avoids extensive turning, chipping, and milling waste. Maximizing the raw material utilization ratio yields substantial cost savings on expensive, high-grade aerospace metals.
