Our production processes adopt environmentally friendly technologies, complying with EU RoHS standards, and all materials are 100% recyclable, meeting global green production requirements 46.

✅ Precision Chain Structure & Excellent Conveying Performance

• Stable Chain Structure Design: Adopt standard roller chain (ANSI, ISO, DIN standards) or customized special chain (double pitch, hollow pin, detachable chain) structures. The chain consists of precision-forged side plates, pins, bushings, and rollers, with tight fitting between components (fit tolerance ≤0.02mm). The roller and bushing adopt wear-resistant design, ensuring smooth transmission and load-bearing capacity up to 50-500kN (depending on chain model) 26.
• Efficient & Adjustable Transmission: The chain drive ensures high transmission efficiency (≥98%), stable speed (adjustable 0.1-5m/s via frequency conversion), and no slipping, suitable for continuous high-load conveying. The chain length can be customized (1-100m) according to production line layout, and the adjustable center distance design facilitates on-site installation and debugging 58.
• Customizable Specifications & Versatile Adaptability: Support customization of chain type (roller chain, conveyor chain, leaf chain), pitch (6.35-50.8mm), plate thickness (2-8mm), and accessory configuration (scrappers, side guides, attachments). Optional accessories include chain tensioners, lubrication systems, and wear strips, adapting to diverse material handling needs (granular, block, packaged, high-temperature materials) 47.

✅ All-Environment Adaptability & Easy Maintenance

• Extreme Environment Resistance: The premium stainless steel material enables excellent adaptability to extreme conditions: ① High-Temperature Environment (up to 1100℃ for 310S stainless steel): Suitable for smelting and high-temperature drying processes in the Middle East and Africa; ② Humid/Corrosive Environment: 316L stainless steel resists acid, alkali, and salt spray corrosion (2500+ hours salt spray test, ASTM B117), suitable for coastal logistics and chemical plants in Southeast Asia; ③ Low-Temperature Environment (down to -40℃): Maintains toughness without brittle fracture, suitable for cold storage logistics in Northern Europe and Canada 69.
• Easy Installation & Low Maintenance: The modular chain design facilitates on-site installation and disassembly, reducing installation time by 30% compared to traditional chains. The stainless steel surface is smooth, easy to clean with water or steam (critical for food/pharmaceutical industries). Optional self-lubricating bushings reduce maintenance frequency, extending maintenance intervals to 10,000+ operating hours. Standardized spare parts are available globally, reducing maintenance costs and downtime 89.
• Safe & Reliable Operation: The precision-forged chain components have no sharp edges, avoiding material damage and operator scratches. Equipped with chain breakage sensors, overload protection, and emergency stop devices when used in complete conveyor systems, ensuring operator and production safety. The chain’s high fatigue resistance ensures long service life (50,000+ operating hours under normal conditions)37.

🏭 Core Manufacturing Process & Professional Surface Treatment

1. Core Manufacturing Processes: Precision-Driven from Forging to Assembly

• Raw Material Forging & Cutting: High-grade stainless steel ingots are forged into blanks (side plates, pins, bushings, rollers) using precision forging machines, enhancing material density and tensile strength. The blanks are cut into required sizes using CNC cutting machines (dimensional error ≤±0.05mm) 47.
• Precision Machining: The forged blanks undergo precision machining: ① Side plates: CNC punching and grinding to ensure hole position accuracy (error ≤±0.02mm) and flat surface; ② Pins & bushings: CNC turning and grinding to ensure surface roughness Ra ≤0.8μm and dimensional consistency; ③ Rollers: Precision rolling and grinding to ensure smooth rotation. Machining precision directly determines the fit between components and transmission stability 26.
• Heat Treatment: To enhance mechanical properties, the machined components undergo targeted heat treatment: ① 304/316L stainless steel: Annealing (1050-1150℃) to eliminate internal stress and improve toughness; ② 310S stainless steel: Solution treatment (1150-1200℃) to enhance high-temperature resistance; ③ Pins & rollers: Quenching and tempering (850-950℃) to improve hardness (HRC 45-55) and wear resistance. The heat treatment parameters are intelligently controlled to avoid material deformation 58.
• Assembly & Riveting: The heat-treated components are assembled into chains using automatic assembly machines. The pins and side plates are riveted using precision riveting machines to ensure firm connection without loosening. After assembly, the chain is adjusted to ensure smooth bending and rotation. For customized chains (hollow pin, detachable), special assembly processes are adopted to meet functional requirements 9.
• Final Inspection & Testing: The finished chains undergo comprehensive inspections, including dimensional accuracy, fit tolerance, tensile strength, and fatigue resistance. The chains are tested for 1000+ hours of continuous operation under rated load to ensure stable performance. Only qualified products are allowed to leave the factory, and complete test reports are provided 9.

2. Professional Surface Treatment: Enhancing Corrosion Resistance & Wear Resistance

• Stainless Steel Surface Treatment: ① Passivation Treatment: Use nitric acid solution to form a dense oxide film on the chain surface, enhancing corrosion resistance (extending salt spray resistance by 50%); ② Polishing Treatment: For food-grade and pharmaceutical-grade chains, the surface is polished to Ra ≤0.2μm, ensuring a smooth, hygienic surface that is easy to clean and complies with FDA and GMP standards; ③ Pickling Treatment: Remove oxide scale and impurities on the surface after heat treatment, improving surface finish and corrosion resistance 59.
• Special Coating Treatment (Optional): For extreme environments: ① PTFE Coating: Enhances anti-adhesion and chemical resistance, suitable for conveying sticky or corrosive materials in chemical and food industries; ② Ceramic Coating: Enhances high-temperature resistance and wear resistance, suitable for high-temperature processing scenarios (up to 800℃); ③ Electroless Nickel Plating: Improves wear resistance and corrosion resistance, suitable for marine and humid industrial environments 68.
• Accessory Surface Treatment: Attachments (scrappers, guides) and sprockets adopt surface treatment matching the chain: ① Stainless steel accessories: Passivation and polishing treatment; ② Carbon steel sprockets: Hot-dip galvanizing or electrostatic powder coating to avoid rust. All accessories are free of sharp edges, ensuring safe operation 37.

3. Strict Quality Control: Guarding Every Process

• Raw Material & Component Inspection: Each batch of stainless steel raw materials is tested for chemical composition (spectrometer) and mechanical properties (tensile strength tester). Machined components are inspected for dimensional accuracy and surface quality using coordinate measuring machines (CMM) 37.
• In-Process Quality Supervision: During forging, machining, and heat treatment, real-time inspections of material density, dimensional accuracy, and heat treatment parameters are conducted. During assembly, inspections of riveting firmness and chain rotation smoothness are performed. All inspection data is recorded and traceable 68.
• Final Performance Testing: Finished chains undergo comprehensive performance tests, including tensile strength, fatigue resistance (10,000+ cycles), corrosion resistance (salt spray test, ASTM B117), high-temperature resistance, and wear resistance. A 2% random sampling method is adopted for each batch, and complete SGS/Intertek test reports are provided for bulk orders 9.
