CUSTOMIZED SOLUTIONS
Casters are one of the most common moving parts in modern industry and daily life, widely used in medical equipment, warehousing and logistics, furniture, machinery, airport carts, and other fields. With the advancement of automation and intelligentization, casters must not only have load-bearing capacity but also continuously improve in terms of wear resistance, slip resistance, quietness, and adaptability to special environments.
Against Heavy-Duty Castersthe rapidly evolving global supply chain, reliable caster suppliers have become a key factor in product selection. A good supplier not only provides high-quality casters but also offers customized solutions to meet the needs of different application scenarios.
For wholesale or purchasing purposes, we recommend contacting Giessen Caster Supplier (email: Giessencasters@gmail.com, website: https://www.giessencasters.com).
The caster production process typically includes the following stages:
Raw material selection and preparation
Component molding and processing
Heat treatment and surface treatment
Final assembly and performance testing
Packaging and shipment
The following table compares the core content of each production stage:
| Production stages | Key processes | Key technical points | Quality control methods |
| Raw material preparation | Selection of steel, rubber, nylon, etc. | Material selection based on load requirements | Chemical composition testing and hardness testing |
| Part molding | Injection molding, stamping, and forging | Mold accuracy and molding consistency | Dimensional inspection and appearance inspection |
| Surface treatment | Electroplating, spraying, and oxidation for rust and corrosion protection | - | Salt spray testing and adhesion testing |
| Final assembly | Assembly of the wheel, bracket, and bearing | Assembly accuracy and clearance | Rotational flexibility testing |
| Finished product testing | Dynamic testing and fatigue testing | Simulation of actual operating conditions | Load testing and wear resistance testing |
The performance of a caster depends on the material selected. Common materials include:
Wheel: polyurethane, rubber, nylon, polypropylene, stainless steel, etc.;
Bracket: carbon steel, stainless steel, aluminum alloy;
Bearing: ball bearings, needle bearings, bushings.
Injection molding: Suitable for nylon and polyurethane wheel bodies, ensuring high precision and batch consistency;
Stamping: Primarily used for forming steel brackets;
CNC turning: Suitable for high-precision manufacturing of bearing inner and outer races.
Electrogalvanizing: Enhances rust resistance;
Electrostatic spraying: Increases corrosion resistance;
Anodizing: Suitable for aluminum alloy brackets, improving wear resistance.
During assembly, strict control of bearing clearance and bracket fit is required to ensure the caster's flexibility and stability during operation. Testing methods include dynamic running tests, rolling resistance tests, and fatigue life tests.
Polyurethane wheel body: Utilizes double-layer injection molding technology, with the outer layer providing wear resistance and the inner layer ensuring cushioning performance.
Rubber wheel body: Requires vulcanization treatment to enhance elasticity and weather resistance.
Nylon wheel body: High-temperature injection molding ensures load-bearing capacity.
Stamping + Welding Process: Suitable for medium- and light-duty casters.
Precision Casting: Mostly used for heavy-duty casters, ensuring strength and impact resistance.
CNC Machining: Suitable for high-end medical equipment casters requiring extremely high precision.
Ball bearings: Low friction, suitable for high-speed and lightweight applications.
Needle bearings: High load capacity, suitable for heavy-duty environments.
Sealing Structure: Prevents dust intrusion and extends life.
Modern casters utilize the following methods to control noise:
Polyurethane silent material;
High-precision bearings;
Built-in shock-absorbing springs or buffer layers.
Static Load Test: Tests the maximum load capacity of the caster when stationary;
Dynamic Load Test: Simulates actual operating conditions;
Abrasion Test: Evaluates wheel durability using a friction tester;
Salt Spray Test: Tests surface corrosion resistance.
Common international standards include: ISO, EN, ANSI, etc. The following table summarizes the testing standards for different caster types:
| Caster Type | Load Requirements | Wear Resistance Requirements | Corrosion Resistance Requirements | Applicable Standards |
| Light-Duty Casters | ≤150 kg | ≥5,000 rolling cycles | Medium | ISO 22883 |
| Medium-Duty Casters | 150–500 kg | ≥10,000 rolling cycles | High | ISO 22884 |
| Heavy-Duty Casters | ≥500 kg | ≥20,000 rolling cycles | High | ANSI ICWM |
Built-in Sensors: Monitor temperature, pressure, and speed;
Intelligent Connectivity: Enable real-time monitoring of caster status in smart warehousing.
Bio-based Polyurethane: Reduces dependence on fossil resources;
Recyclable Steel and Aluminum: Meets green manufacturing standards.
