Cylinder bottom forgings from Quanzhou Weforging Machinery Manufacturing Co., Ltd are hot-forged components designed for hydraulic cylinder assemblies in heavy machinery. These forgings are manufactured from carbon steel 1045 or alloy steel 4140, with precise dimensional tolerances to ensure seamless integration into hydraulic systems. The forging process enhances grain flow and structural integrity, making them suitable for high-pressure environments up to 300 bar.
The material selection follows standard industrial practices for load-bearing hydraulic components. Carbon steel 1045 offers good machinability and moderate strength, while alloy steel 4140 provides higher toughness and fatigue resistance, commonly used in construction equipment and industrial presses. Surface finish is typically ground to 3.2 µm Ra unless otherwise specified, and no surface coatings are applied unless requested by the buyer.
These forgings are primarily purchased by OEM manufacturers of hydraulic cylinders for mining, agriculture, and civil engineering machinery. Buyers typically order in batches of 500 units or more, with lead times of 30 to 45 days depending on order volume. Packaging is in wooden crates with rust-inhibiting paper, and shipments are commonly delivered under FOB Xiamen or CIF terms. Confirm dimensional drawings and heat treatment certificates before placing bulk orders.

Quanzhou Weforging Machinery Manufacturing Co., Ltd operates from Jinjiang City in Fujian Province, China, with a facility in the Pingkeng Industrial Zone. The company specializes in custom and standard forgings for hydraulic systems, with equipment for hot die forging and basic post-processing. The listing shows no verified certifications, no published production capacity, and no client references. Response rate and average response time are not recorded, indicating limited direct buyer engagement.
The supplier does not claim to hold ISO certification, export licenses, or third-party quality audits. There is no mention of in-house testing labs or metallurgical analysis capabilities. Buyers should request material test reports and dimensional inspection reports before shipment. The company's focus appears to be on volume production for industrial components rather than engineering support or custom design services.
Cylinder bottom forging is a critical structural component used in hydraulic cylinder assemblies for heavy machinery, construction equipment, and industrial presses. These forgings are manufactured from high-strength carbon or alloy steel via hot die forging to ensure superior mechanical properties and pressure resistance. Widely sourced from global forging suppliers, cylinder bottom forgings are traded internationally for OEM hydraulic equipment manufacturing and aftermarket replacement needs.

Before ordering, verify the exact material grade (1045 or 4140), hardness range, and dimensional drawings with the supplier. Confirm whether the forgings are delivered in raw forged state or with machining allowances. Request material test reports for tensile strength, hardness, and chemical composition. Do not assume compliance with international standards unless explicitly documented.
Lead time typically ranges from 30 to 45 days after order confirmation, depending on batch size. Packaging is in wooden crates with rust inhibitors. Common trade terms are FOB Xiamen or CIF, but confirm Incoterms in writing. Payment is often via T/T 30% deposit and 70% before shipment. Ensure the supplier provides a commercial invoice, packing list, and bill of lading with clear product identifiers.
For quality assurance, request a sample batch for dimensional inspection and surface evaluation. Verify that the surface finish meets the required Ra value and that there are no forging laps, cold shuts, or scale residues. Insist on a batch traceability number linked to material certification. Consider third-party inspection at origin if the order exceeds 5,000 units or is for safety-critical applications.
