How Custom Molded Rubber Parts Enhance Product Performance and Longevity |

Due to their unparalleled design flexibility and remarkable physical and chemical properties, custom moulded rubber components play an essential role in enhancing the performance and extending the life cycle of many products. The role of customized moulded rubber parts on product performance and service life is systematically introduced in this article from aspects of material property adaptation, structural optimization design, vibration and noise attenuation and sealing protection.

The first one is the adaptation of the characteristics of material to meet the requirements of different applications

Yes, one of the reasons for this is that custom moulded rubber parts have a high degree of flexibility with regards to material selection, which allows one to choose the most appropriate rubber material suited to the product's end use environment and performance parameters.

1.1 Special Environment: Such as high temperature, low temperature, corrosive medium and other extreme working environment, you can choose high-temperature fluorine rubber (FKM), low-temperature silicone rubber (VMQ), oil-resistant nitrile butadiene rubber (NBR) and other special rubber material. Remove awareness, as the material performance does not meet the requirements, to prevent rubber parts in the harsh environment of work stability, resulting in product performance degradation, shorten the life. For example, all types of high temperature and oil resistant fluoro rubber seal selection automobile engine, can guarantee the normal operation of the engine and prolong the service life.

1.2 Mechanical properties optimization: According to the required mechanical properties of the product can choose high elastic, high strength or high wear-resistant rubber materials. For example, some parts need to bear the impact load, you can choose natural rubber ( nr ) or polyurethane rubber (pu), and some parts need to bear the bias compression load for a long time, you can consider strong rubber material with resistance to compression, permanent deformation is small. All but even better mechanical properties of the materials increase the mechanical resistance and durability of the elements.

1.3 Functionalization: In addition to the basic physical and chemical properties for practical purposes, rubber materials can also possess thermally conductive, flame retardant, antistatic and other characteristics through blending of special fillers or modifiers. It can meet the demand of making parts in special application scenarios and increase the product security, and the reliability.

Simultaneously, the structural optimization design is crucial to guarantee the accuracy of performance optimization.

These rubber parts can be molded to be wide-ranging lengths, volumes, forms and arrangements that enable you to pinpoint directly how you want to improve a particular product performance.

2.1 Mold design: Custom mold rubber parts can be designed into complex shaped structures, which can adapt to the product's special mounting space and connection mode. Furthermore, the process will be marked on the transmission and force components to optimize the stress distribution of the parts, and to improve its load-bearing capacity and service life.

2.2 Local reinforcement: The regional reinforcement area (stress concentration area) of the component can use thickening the material or changing the geometry of the material, especially improvement and adding the reinforcement material, etc. to improve the components[2]: Abrasion resistance and fracture toughness. The structural feature of local performance enhancement can ensure the service life of the part key, and the maintenance cost of the product is very low.

(3) Integration of multiple functions: Rubber parts can be integrated with other materials (such as metal and plastic) through the molding process to achieve multiple functional integration. Features:Integrated molding of the rubber seal and metal skeleton improves the sealing effect and the installation strength;Integrated molding of the rubber cushion and the metal bracket simplifies the installation process and improves the stability of the structure.

The better user experience, and other advantages

But it has a fairly elastic and damped behavior. including its that makes it capable of absorbing vibration energy and reducing general noise propagation.

3.1 Impact LoadSome parameters are utilized to replace rubber parts as custom molded rubber pieces for padding pads, shock absorber pads, etc. to absorb shock loads, decrease the amplitude of vibration products, and preventing products from being damaged by impact. The automobile suspension system rubber shock absorber can effectively attenuate the bumpy feeling of the helicopter and obtain a more comfortable ride.

3.2 The high-quality rubber seals can make to keep water/sand/oil etc. Out, and assure the internal core with no corrosion or wear. Rubber seals also work to reduce gas and liquid leaks, increasing the efficiency and reliability of the product at the same time.

3.3 Noise control: If the vibration source and the vibration propagation path of the equipment can install a certain rubber vibration isolation pad or other anti-noise material, it can effectively inhibit noise. When used to suppress vibration in mechanical equipment, rubber vibration isolation pads can reduce structural noise caused by equipment vibration and improve the working environment.

Use class 4, Sealed barrier, prolong the service life of the product.

Well resistant to corrosion, rubber material also has good sealing performance, which can protect the internal parts of the product from the external environment to a greater extent, so as to extend the service life of the product.

4.1 Anticorrosive protection: rubber material has good acid & alkali resistance, salt spray resistance, ultraviolet resistance and other properties, can effectively prevent product internal parts due to corrosion failure. In Marine application, rubber coatings or seals are widely used to overcome seawater corrosive properties protecting metal structures and increasing their life span.

4.2 Anti-aging protection: As antioxidants and light stabilizers were incorporated into the rubber material, the anti-aging ability of rubber material increases, which extends its service life. You should pay special attention to the anti-aging measures when using rubber parts that are exposed to the sun for a long time.

4.3 Contaminant Protection: Custom injection molded rubber components can act as seals and dust caps that protect the product from contaminating particles (dust, water, oil) that could affect sensitive components. For example, in precision instruments, rubber seal can better block dust into the optical system to ensure imaging quality.

V. Conclusion

Conclusion — Custom moulded rubber parts are essential in many applications as they provide the possibility to tailor the material property, optimise the structural material design; damp vibration, reduce noise as well as environmental sealing to achieve better performance and longer service life of a product. With the continuing development of engineering technology and the emergence of new materials,custom moulded rubber parts will be used in more fields. So effectively improve the further performance and life will rely on the adjustment of rubber material and optimization of the process.
