Robot-Grade Material Selection: Wear Resistance, Load-Bearing & ISO 10218 Compliance Challenges

Created on 05.21

Material selection is the foundation of robot manufacturing. Robot parts (robot arm components, grippers, reducers, sensor brackets) must meet three core requirements: wear resistance (adapt to frequent movement and friction), load-bearing (withstand working load), and ISO 10218 compliance (meet robot safety standards). However, many robot OEM manufacturers face material selection pain points: choosing materials with poor wear resistance/load-bearing capacity, materials that fail ISO 10218 compliance, or inconsistent material performance between batches, leading to part damage, robot failure, and safety risks. Based on our experience in robot material selection and supply chain management, we analyze the core challenges and provide practical selection solutions.

1. Core Pain Points of Robot-Grade Material Selection

• Poor Wear Resistance & Load-Bearing Balance: Choosing ordinary industrial materials instead of robot-grade materials leads to rapid wear of parts (e.g., robot arm joints, grippers) or insufficient load-bearing capacity, reducing robot service life and increasing maintenance costs.

• ISO 10218 Compliance Risks: Choosing non-compliant materials leads to robot failure to meet industrial safety standards, resulting in inability to pass certification and market access restrictions.

• Unstable Batch Consistency: The material performance (hardness, wear resistance, load-bearing capacity) of different batches is inconsistent, leading to unstable product quality, increased scrap rate, and difficulty in mass supply to robot manufacturers.

2. Key Requirements & Material Selection Guidelines

1. Wear Resistance & Load-Bearing (Compliant with Robot Industry Standards)

• Core Requirement: Parts must withstand frequent movement, friction, and working load, meeting robot industry wear resistance and load-bearing standards.

• Recommended Materials: 

• Metal parts: Aluminum alloy 7075 (high load-bearing, wear-resistant, lightweight), stainless steel 316L (wear-resistant, corrosion-resistant), carbon steel (high load-bearing, wear-resistant) for robot arms, reducers, and grippers.

• Plastic parts: Engineering-grade POM (wear-resistant, low friction), PC/ABS alloy (impact-resistant, load-bearing), TPU (flexible, wear-resistant) for non-load-bearing parts and accessories.

• Our Guarantee: All materials we use are robot-grade, ISO 10218 compliant, from certified suppliers, with complete material certificates (CoC), mechanical performance test reports, and batch consistency test reports, ensuring wear resistance and load-bearing meet industry standards.

2. ISO 10218 Compliance Requirements

• Core Requirement: Materials must comply with ISO 10218 standards (robot safety requirements), ensuring robot operation safety and avoiding mechanical failure and safety accidents.

• Selection Strategy:        

• Cooperate with ISO 10218 certified suppliers, and require suppliers to provide compliance test reports for each batch of materials.

• Prioritize the selection of materials with stable mechanical performance and impact resistance to avoid safety risks caused by material failure.

• Applicable Scenarios: All industrial robot parts (robot arms, grippers, reducers, sensors) that need to meet industrial safety standards, ensuring robot operation safety.

3. Batch Consistency Control

• Supplier Management: Cooperate with fixed, certified robot material suppliers, sign long-term supply agreements, and require suppliers to provide batch consistency test reports.

• Incoming Material Inspection: For each batch of materials, we conduct incoming inspection (material composition, wear resistance, load-bearing capacity), and only put them into production if they meet the requirements.

• Process Matching: Adjust machining parameters according to the performance of each batch of materials, ensuring that the final product quality is stable and meets robot manufacturer supply standards.
