The main advantages of Jianlong stainless steel sink stretch forming hydraulic press

The "stainless steel sink stretch forming hydraulic press" developed and produced by China Jianlong Hydraulic Technology has many significant advantages in the manufacturing process, especially suitable for high-precision and complex shape processing of difficult-to-deform materials such as stainless steel. The main advantages are as follows:

1. High forming force and stability

1.1 Large tonnage pressure: The hydraulic press can provide hundreds to thousands of tons of stable pressure, easily cope with the high strength of stainless steel (such as the work hardening characteristics of 304 stainless steel), and ensure one-time stretching of deep troughs or complex curved surfaces.

1.2 No impact load: The hydraulic system pressure is uniform, avoiding the instantaneous impact of mechanical stamping and reducing the risk of material cracking.

2. Stretching depth and complex shape advantages

2.1 Deep stretching ability: Through multiple stretching (such as pre-stretching and then finishing), it can form a deep sink (such as ≥200mm) with uniform wall thickness.

2.2 Complex structure adaptation: The hydraulic press has adjustable speed, which is suitable for the forming of R-angled, stepped, and special-shaped sinks, and the mold adaptability is stronger.

3. Surface quality and precision control

3.1 Low scratch rate: Hydraulic presses form slowly (speed is usually ≤15mm/s), and with lubrication process, it can reduce scratches on the stainless steel surface and reduce subsequent polishing costs.

3.2 High dimensional accuracy: Closed-loop hydraulic control systems (such as proportional valves + grating rulers) can accurately control the slider stroke (±0.1mm) to ensure that the edge of the sink is flat and the drainage groove is consistent.

4. Process flexibility

4.1 Adjustable clamping force: The independent hydraulic clamping system can dynamically adjust the clamping force (such as 20~100 tons) to prevent edge wrinkling during stretching (common in large-sized sinks).

4.2 Multi-process integration: A hydraulic press can integrate stretching, punching, flanging and other processes (such as completing the forming of the sink body + overflow hole at one time), reducing equipment investment.

5. High material utilization

5.1 Reduce waste: Hydraulic stretching can optimize the layout design, and with the nesting process, the utilization rate of stainless steel plates can be increased by 10%~15%.

5.2 Rebound control: The pressure holding function (such as 2~5 seconds) effectively suppresses the rebound of stainless steel and reduces secondary correction.

6. Long mold life

6.1 Low wear: The hydraulic press has no rigid impact, the mold (especially the rounded corners of the die) has little wear, and the life is 30%~50% longer than that of the mechanical press.

6.2 Low mold cost: The requirements for mold materials are relatively low (such as cast steel can be used instead of cemented carbide), which is suitable for small and medium-sized batch production.

7. Energy saving and convenient maintenance

7.1 On-demand energy supply: Modern hydraulic presses use variable pumps, which only supply oil at high pressure during working, and the energy consumption is reduced by 20%~30% compared with traditional mechanical presses.

7.2 Low failure rate: The hydraulic system has no complex transmission parts such as gears and cranks, and is easy to maintain.

In short, the stretch forming of stainless steel sink hydraulic presses is particularly suitable for products with high requirements for surface quality and structural complexity, taking into account efficiency and cost, especially in the manufacture of mid-to-high-end sinks (such as hand-made sinks and special-shaped sinks).
