Design and Molded with Rubber Bellows
When designing custom molded rubber bellows, focus should be placed on its functional requirements, structural design and material properties. Ensure that the bellows has good expansion, bending and durability, and at the same time design a reasonable corrugated shape and wall thickness distribution, taking into account flexibility and strength. Select materials suitable for the use of the environment to meet the requirements of high-temperature resistance, corrosion resistance and fatigue resistance.
In addition, it is also necessary to consider the type of fluid, and pressure adaptability, as well as the optimization of the overall weight and size, to ensure perfect compatibility with the customer’s equipment, to enhance the reliability and application value of the product.
Processes commonly used to produce custom rubber bellows include compression molding, injection molding and extrusion.
- Compression molding is suitable for small-lot production with low tooling costs but has a long production cycle.
- Injection molding is highly efficient, suitable for high-volume production, and capable of achieving complex shapes, but has higher tooling costs.
- Extrusion is suitable for the continuous production of simple tubular corrugations but has limited adaptability for precision and complex shapes.
Each process has its own advantages and disadvantages, and the optimal solution can be selected according to the order size, design complexity and cost requirements to achieve a balance between performance and economy.
