3.2 Manufacturing Process: From Raw Aluminum to Finished Crutch
6061/7075 aluminum & SUS 304 steel are selected for high strength and light weight. Smelting ensures material uniformity and impurity removal.
Aluminum is extruded into tubes under high pressure (200-400MPa); steel parts use lost-wax casting for complex joint shapes.
Automated CNC centers process telescopic slots, jointing holes, and ergonomic grips—ensuring repeated precision up to 0.02mm.
Tubes undergo anodizing (Type II or Type III, ASTM B580-compliant) for extreme corrosion resistance, color coding, and safety.
Manual & robotic assembly, ISO 9001 quality checks, fatigue/bending/impact tests per ISO 11334 standards. Batch-certified.
Gamma irradiation or ethylene oxide sterilization for medical use. Retail & bulk packaging per customer specs.
Key Technical Processes Explained
- Anodizing: Electrochemical treatment that hardens aluminum oxide layer, achieving up to 25μm thickness for superior corrosion and scratch resistance.
- CNC Machining: Ensures dimensional accuracy; reduces assembly tolerance so telescopic mechanisms never jam or rattle under load.
- Quality Testing: Each batch tests 15,000 load cycles; ISO/ANSI/FDA standards applied. Failure rate < 0.03% annually (2021-2023 data).

10. FAQs: Professional FAQ on Aluminum Underarm Crutches
Q1: What materials are used in premium aluminum underarm crutches?
A: Premium crutches use 6061 or 7075 aircraft-grade aluminum for the tubing, often combined with stainless steel or high-strength engineering plastics at joint points. Medical-grade rubber is typically used for tips and grips.
Q2: What is the difference between anodizing and powder coating in crutch manufacturing?
A: Anodizing is an electrochemical process that creates a robust oxide layer on aluminum, greatly improving corrosion resistance and colorfastness. Powder coating is a surface layer providing basic protection but may chip after extended use.
Q3: What load capacity standards are referenced?
A: Most aluminum underarm crutches are tested under ISO 11334-1 (minimum 100 kg). High-end models like CS-01S exceed 140 kg load (certified via third-party labs such as SGS & TÜV).
Q4: Are the crutches height and handle positions adjustable?
A: Yes. Standard models provide 10–13 slots for height adjustment and allow handle/grip position changes, ensuring customizable fit for users from 140–200cm tall.
Q5: What industry certifications should I request?
A: Ensure compliance with ISO 11334, FDA (21 CFR 890.2130), CE (MDR 2017/745), and ANSI A117.1. These ensure medical-grade safety, labeling, and accessibility.
Q6: What is the typical lifespan of a quality aluminum underarm crutch?
A: For models with anodized/aluminum and steel construction, the typical physical service life is 5–8 years (based on 15,000 loading cycles in testing). Rubber tips and grips are considered consumables and are user-replaceable.
Q7: Is anti-slip tested under wet conditions?
A: Yes. All medical-grade crutches undergo ANSI A117.1, Section 302 anti-slip floor testing, ensuring grip on dry/wet linoleum, tile, and concrete. CS-01S passed with >0.75 dynamic friction.
