Quality Inspection Equipment
We have our own laboratory in the factory to inspect and test the entire processing procedure:
- Raw Material Inspection: Verify the material and dimensions, and use microscopes and CHINAMFG hardness testers to check the metallography and hardness of the materials.
- Parts Inspection: Use CMM and gauge rods to check the specifications and threads of the parts.
- Weld Seam Inspection: Use ultrasonic flaw detectors to check weld seam defects and ensure sealing.
- Cylinder Performance Testing: Use cylinder test benches to test cylinder performance and oil particle counters to measure oil quality.
- Paint Inspection: Use coating thickness gauges and cross-cut testers to check the paint thickness and adhesion. All test results are recorded and quality inspection reports are provided.
Welding
Our welding process includes:
- Visual Inspection: Check the weld seam appearance to ensure it meets standard requirements.
- Mechanical Property Testing: Evaluate the strength, ductility, and toughness of the welded parts.
- X-ray Inspection: Ensure there are no internal gaps.
- Ultrasonic and Magnetic Particle Testing: Further check the quality of the welds.
Test Bench
We use Hallite ,Trelleborg,Parker brand seals and offer a one-year warranty for our cylinders. Each cylinder undergoes weld seam inspection, leak detection, and pressure testing after assembly to ensure quality and performance meet design requirements. Additionally, we engrave part numbers and production dates on our products for tracking and after-sales service.
Painting
We have a semi-automated painting line. Before painting, we perform sandblasting to remove surface scale and rust, increasing the adhesion strength between the coating and the substrate. After electrostatic dust removal, the products are transported to the painting room via a conveyor belt, where robotic arms apply the paint evenly. We are capable of marine-grade painting, ensuring that the coatings are highly resistant to corrosion and durable.
After painting, the products undergo drying and cooling, followed by tests for hardness, thickness, and adhesion to ensure the painting quality. All test results are recorded in the OQC report, which is printed and attached to the packaging box, accompanying the products to the customer.
Packaging & Shipping
Before shipping, we check for any surface cracks or collision marks on the cylinders, ensure protective sealing plates on all oil ports, verify the condition of the oil port threads, and re-tighten all fastening bolts. Each cylinder is labeled with detailed information, including bore diameter, stroke, and working pressure. We use individual plastic bags, cardboard boxes, and wooden crates for packaging, along with plastic film and foam pads for protection. After shipping, we send packing pictures to the customers to ensure all goods have been properly loaded in China.

Handling the Challenges of Minimizing Fluid Leaks and Contamination in Hydraulic Cylinders
Hydraulic cylinders face challenges when it comes to minimizing fluid leaks and contamination, as these issues can impact the performance, reliability, and lifespan of the system. However, there are several measures and design considerations that help address these challenges effectively. Let's explore how hydraulic cylinders handle the challenges of minimizing fluid leaks and contamination:
- Sealing Systems: Hydraulic cylinders employ advanced sealing systems to prevent fluid leaks. These systems typically include various types of seals, such as piston seals, rod seals, and wiper seals. The seals are designed to create a tight and reliable barrier between the moving components of the cylinder and the external environment, minimizing the risk of fluid leakage.
- Seal Material Selection: The choice of seal materials is crucial in minimizing fluid leaks and contamination. Hydraulic cylinder manufacturers carefully select seal materials that are compatible with the hydraulic fluid used and resistant to wear, abrasion, and chemical degradation. This ensures the longevity and effectiveness of the seals, reducing the likelihood of leaks or premature seal failure.
- Proper Installation and Maintenance: Ensuring proper installation and regular maintenance of hydraulic cylinders is essential for minimizing fluid leaks and contamination. During installation, attention should be given to proper alignment, torqueing of bolts, and adherence to recommended procedures. Regular maintenance includes inspecting seals, replacing worn-out components, and addressing any signs of leakage promptly. Proper maintenance practices help identify and rectify issues before they escalate and cause significant problems.
- Contamination Control: Hydraulic cylinders incorporate measures to control contamination and maintain fluid cleanliness. This includes the use of filtration systems, such as in-line filters, to remove particles and contaminants from the hydraulic fluid. Additionally, hydraulic reservoirs often have breathers and desiccant filters to prevent moisture and airborne contaminants from entering the system. By controlling contamination, hydraulic cylinders minimize the risk of damage to internal components and maintain optimal system performance.
- Environmental Protection: Hydraulic cylinders may be equipped with protective features to safeguard against external contaminants. For example, bellows or protective boots can be installed to shield the rod and seals from debris, dirt, or moisture present in the operating environment. These protective measures help extend the life of the seals and enhance the overall reliability of the hydraulic cylinder.
In summary, hydraulic cylinders employ sealing systems, appropriate seal materials, proper installation and maintenance practices, contamination control measures, and environmental protection features to handle the challenges of minimizing fluid leaks and contamination. By implementing these measures, manufacturers can ensure reliable and long-lasting hydraulic cylinder performance, minimize the risk of fluid leakage, and maintain the cleanliness of the hydraulic system.
