Molding Process of Our Rubber Diaphragm
Our rubber diaphragm is typically molded using a process such as compression molding, transfer molding, or injection molding.
However, the specific molding process used depends on various factors such as the size, complexity, and quantity of the diaphragms being produced, as well as the properties desired in the final product.

Fabric Reinforced Rubber Diaphragm
LINDAS offers Fabric Reinforced Rubber Diaphragm that is made of rubber material reinforced with fabric such as polyester or nylon.
It is commonly used in applications where a flexible seal is needed to separate two different environments. It includes pressure vessels, pumps, and valves.
The fabric reinforcement provides increased strength and durability, allowing the diaphragm to handle high pressure and temperature variations while maintaining its flexibility. Fabrics used include polyester, polyamide, cotton, and more.
Homogenous Rubber Diaphragm
A homogeneous rubber diaphragm is a type of flexible membrane made of a single layer of homogeneous rubber material.
The rubber material used in the diaphragm must have the desired properties such as strength, elasticity, and durability, as well as compatibility with the fluids or gases it will be exposed to.
The diaphragm’s shape and thickness are designed to meet the specific requirements of each application.
Features and Advantages
- Wear and tear resistance
- Perfect fit for superior sealing
- Less friction required
- Durable
- Resistance to high pressure
- Flexibility
- Cost-effective
- Easy to install
Rubber Diaphragm Durometer
In the case of rubber diaphragms, durometer refers to the measurement of the rubber material’s hardness. This is important because the hardness of the rubber affects its ability to seal, resist wear and tear, and maintain its shape during use.
The most commonly used durometer scale is the Shore A scale, which measures the hardness of soft to hard rubber materials.
The durometer value of a rubber diaphragm depends on the specific application. As well as the required properties of the rubber material, such as flexibility, compression set, and chemical resistance.
