Import Taxes:

When importing hydraulic machines, the costs typically include customs duties, value-added tax (VAT), and potentially additional fees such as handling or documentation charges. The import duties are determined based on the HS code of the machine, which aligns with the country’s import policy. These duties generally range from 0% to 10%, with tax rates typically falling between 15% and 25%. We recommend consulting a local customs expert to ensure precise cost estimations.

Logistics Costs:

The logistics cost depends on the chosen transportation mode (such as sea or air freight) and the applicable insurance and storage fees. Sea freight tends to be more cost-effective for larger shipments. When selecting delivery terms, we suggest choosing EXW if you wish to bear the full cost of transportation and insurance, or CIF if you’d prefer the seller to include those in the price. We advise you to plan for potential shipping risks by choosing the appropriate insurance to prevent loss or damage during transit.

We support T/T (telegraphic transfer) as the primary payment method, as it is efficient and secure. A 30%-50% advance payment is required before production begins, and the remaining balance should be paid before shipment.

Please provide the company and order details for quick verification at the time of payment, with the usual processing time being 1-3 business days (subject to bank processing time).

If installment payments or other payment terms (such as large order payments) are required, these can be negotiated in advance with the supplier to ensure mutual benefit.

Core Factors in Hydraulic Presses

1. Core Performance Parameters

The public standard positions for hydraulic presses are mainly based on three core performance indicators: maximum pressure (for example, 1000 tons is typically used in the medium-sized range, 500 tons in small-sized models); stroke length determines the required working area, which must match the working pressure; the opening height also affects the machine’s performance.

If these parameters are mismatched, it could lead to an inefficient processing rate. It is recommended to adjust based on the largest working area and material hardness parameters to ensure precision in key points.

2. Precision and Stability Requirements

Pressure control accuracy (≤1%) and speed adjustment time (fast pressure rise), temperature fluctuation (≤1°C deviation) : These factors are critical to product quality. For instance, pressing requires high precision to avoid errors, while materials must be carefully chosen to ensure minimal deformation.

Also, frame rigidity (such as the use of a H-frame) and fine precision (0.02mm level) can help minimize potential errors in molding. For parts with high precision (e.g., precision electronic devices), prioritizing these factors is recommended.

3. Function Expansion and Flexibility

Automatic interface (PLC/machine interface), safety protection, and energy efficiency indicators (such as system life extension) are essential for enhancing long-term production and reducing costs.

For example, hydraulic presses with the energy efficiency of 30%-50% are common, but they require multiple operational interfaces for higher functionality. Equipment setup should align with production needs, and the process must be tailored to ensure it meets customer needs and complies with project standards.

Summary

Hydraulic presses used in industrial manufacturing are required to meet specific “precision” standards. The machine’s performance and production efficiency are significantly affected by the configuration and setup of various components, such as the frame structure and power mechanisms. We can provide solutions tailored to these needs, ensuring that the machine performance meets industry standards and provides optimal efficiency in production.

It is recommended to regularly check the following core components:

  • Hydraulic oil: Check every 3-6 months to avoid contamination or oxidation, which could lead to system failure.
  • Seals: Check monthly to ensure pipes and connections are not leaking; seals need to be replaced when worn.
  • Filter: Check every season to ensure proper filtration, and prevent contamination of the hydraulic system.
  • Electrical components: Inspect the PLC and sensor connections for stability to avoid operational errors.

Common causes include:

  • Oil leakage: If the oil is leaking from the pipes or joints, causing air intake, it could block the flow.
  • Hydraulic pump: If the flow rate is too high, it can cause excessive noise and high-pressure settings.
  • Machine setup: If the equipment is not installed properly or is on uneven ground, it could cause operational noise. It is recommended to adjust the alignment and level the machine.

The following methods can be used to evaluate:

  • Color and appearance: If the oil appears darker and has a burnt smell, it indicates it is overdue for a change.
  • Viscosity test: Use a viscosity meter to check. If the viscosity deviation exceeds 15%, it indicates the oil has degraded.
  • Contamination check: Use particle contamination tests (such as NAS 1638 grade > 84) to check the level of contamination.

Follow these priority checks:

  • Pressure sensor: Calibrate or replace the faulty pressure sensor.
  • Piping/fittings: Inspect the pipelines and fittings to check if the control signals are normal.
  • Oil temperature: If the oil temperature exceeds 60°C, the system pressure may fluctuate, requiring cooling efficiency checks.

Follow these steps:

  • System purge: Run the equipment for 10-15 minutes, venting the pipeline to remove air.
  • Oil preheating: Preheat the oil to above 20°C before restarting (especially in colder regions, ensure proper oil temperature).
  • Function testing: Perform pressure, speed, and process parameter tests to ensure there are no blockages or leaks.
