Application and optimization of high rebound caster anti-yellowing agent in caster manufacturing of medical equipment
Introduction: Casters, the "invisible assistant" of medical equipment
While casters are inconspicuous in hospitals, clinics or laboratories, they play a crucial role. They are the "invisible assistants" of medical equipment, allowing hospital beds, carts, instruments, etc. to move easily, saving physical strength for medical staff and improving work efficiency. However, these seemingly simple components actually contain complex technological and technological requirements. Especially for medical equipment with high load and high frequency use, the quality of casters directly affects the service life and safety of the equipment.
Modern caster materials are mostly polyurethane (PU), which is popular for its wear resistance, shock absorption and silent effects. However, as the use time increases, casters may experience problems such as aging, deformation and even yellowing. These problems not only affect the appearance, but may also reduce the performance of casters and increase maintenance costs. Therefore, how to improve the durability and yellowing resistance of casters by improving the manufacturing process has become a difficult problem that the industry needs to solve.
In recent years, a new material called "High Resilience Caster Anti-Yellowing Agent" has gradually emerged. It can not only significantly improve the elasticity of casters, but also effectively inhibit the occurrence of yellowing, bringing new possibilities to the manufacturing of casters in medical equipment. This article will deeply explore the mechanism of the anti-yellowing agent of high rebound casters and its specific application in the manufacturing of casters of medical equipment, and analyze its actual effect on product quality improvement in combination with relevant domestic and foreign literature.
Next, we will conduct detailed discussions on technical principles, product parameters, manufacturing process optimization and actual cases, striving to present readers with a comprehensive and practical knowledge system. Whether it is an ordinary reader who is interested in casters or a professional who wishes to optimize production processes, this article will provide you with valuable reference.
Technical principles of high rebound castor anti-yellowing agent
1. Mechanism of action of anti-yellowing agent
High resilience castor anti-yellowing agent is a special chemical additive that mainly plays a role through the following two mechanisms:
- Antioxidation: Casters will be affected by ultraviolet rays, oxygen and other environmental factors during long-term use, causing molecular chains to break and free radicals, thereby causing yellowing. The antioxidant components in the anti-yellowing agent can capture these free radicals and delay the occurrence of the oxidation reaction.
- Ultraviolet absorption: Some anti-yellowing agents contain ultraviolet absorbers, which can effectively absorb ultraviolet energy and convert them into harmless heat release, thereby reducing the damage to caster materials by ultraviolet rays.
These two mechanisms work together to enable the casters to maintain their original color and performance after long-term use, avoiding yellowingCaused appearance and function problems.
2. Source of high rebound characteristics
The reason why high rebound casters have excellent elasticity is closely related to their material structure. Certain components in the anti-yellowing agent can promote the formation of a more regular molecular network structure of the caster material, which not only enhances the mechanical properties of the material, but also improves its ability to recover from deformation. Simply put, when the casters are under pressure, this regular structure can be restored to its original state faster, thus showing higher resilience.
In addition, anti-yellowing agents can improve the fluidity of caster materials, making them easier to form during injection molding or casting, while reducing the generation of internal bubbles and cracks, thereby further improving the durability and stability of the product.
3. Summary of technical principles
Through the above mechanism, the high-resilience castor anti-yellowing agent not only solves the problem that traditional castors are prone to yellowing, but also gives castors a better elastic performance. This comprehensive performance improvement makes casters more comfortable when facing complex usage environments, providing reliable guarantees for the efficient operation of medical equipment.

|---|---|---|
| Yellow change level (ΔE*) | 8.5 | 1.2 |
| Rounce rate (%) | 45 | 72 |
| Abrasion-resistant life (hours) | 2000 | 4500 |
It can be seen from the table that after adding high rebound caster anti-yellowing agent, the performance of casters has been significantly improved. This not only means higher product quality, but also represents lower maintenance costs and longer service life.
Manufacturing process optimization strategy
1. Material selection and proportion optimization
In the manufacturing process of casters for medical equipment, the selection of materials is crucial. The introduction of high-resilience castor anti-yellowing agent requires manufacturers to re-evaluate and optimize the ratio of raw materials. Specifically, the ratio of anti-yellowing agent to other additives needs to be precisely controlled based on the expected use and environmental conditions of the casters.
For example, when producing casters for intensive care units, the amount of anti-yellowing agent should be appropriately increased to cope with high-intensity ultraviolet irradiation; while casters used in ordinary wards can slightly reduce the proportion of anti-yellowing agent to balance cost and performance. This refined proportional adjustment helps to achieve the best utilization of resources while ensuring consistency in product quality.
2. Improving injection molding process
Injection molding process is one of the key links in the manufacturing of casters in medical equipment. In order to give full play to the role of high-resistance castor anti-yellowing agent, a series of improvements to the injection molding process must be made:
- Temperature Control: Anti-yellowing agents are temperature sensitive, and excessive processing temperatures may cause them to decompose or fail. Therefore, during the injection molding process, the temperature of the mold and melt needs to be strictly controlled. It is usually recommended to maintain the mold temperature between 30-50℃ and the melt temperature within the range of 180-220℃.
- Injection Speed: Appropriate injection speed can ensure uniform distribution of materials and avoid local accumulation or voids. It is generally recommended to use medium-speed injection, which can not only ensure the molding quality but also do not cause excessive shear to the material.
- Support time: Extending the holding time helps to eliminate internal stress and improve the overall strength of the casters. Research shows that the holding time is 10-15In seconds, the product has good mechanical properties.
3. Post-processing technology upgrade
In addition to the injection molding process, the post-processing steps are also an important factor in determining the quality of the caster. The application of high-resistance castor anti-yellowing agent requires manufacturers to upgrade traditional post-treatment methods:
- Cooling method: Rapid cooling may cause cracks inside the caster, so it is recommended to adopt a progressive cooling method to gradually reduce the temperature to reduce internal stress accumulation.
- Surface treatment: By spraying or applying a protective film, the casters can further enhance their yellowing resistance and wear resistance. This method is especially suitable for casters that require long-term exposure to UV light or in harsh environments.
4. Practical cases of process optimization
A well-known medical device manufacturer used high-resistance casters to produce their new bed casters and comprehensively optimized the manufacturing process. After a year of actual use test, the results show:
- The yellowing level of casters has been reduced from the original 8.5 to 1.2, and the appearance remains smooth as new;
