Quality Inspection Equipment

We have our own laboratory in the factory to inspect and test the entire processing procedure:

1. Raw Material Inspection: Verify the material and dimensions, and use microscopes and CHINAMFG hardness testers to check the metallography and hardness of the materials.
2. Parts Inspection: Use CMM and gauge rods to check the specifications and threads of the parts.
3. Weld Seam Inspection: Use ultrasonic flaw detectors to check weld seam defects and ensure sealing.
4. Cylinder Performance Testing: Use cylinder test benches to test cylinder performance and oil particle counters to measure oil quality.
5. 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:

1. Visual Inspection: Check the weld seam appearance to ensure it meets standard requirements.

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.
