Rubber latches are latches made of rubber or are composed of rubber components. They are used in the automotive, aerospace, and medical equipment industries due to their flexibility, durability, and non-abrasive properties . Rubber latches provide secure and tight closure of doors, lids, and openings for enclosures where surfaces connect.
The structure of a rubber latch includes a flexible rubber strap that is attached to a frame and can stretch to secure and close an opening. The key feature of a rubber latch is its elasticity and stretchability such that it can be pulled over a hook, knob, or some form of anchor point. The placement of the strap creates tension that keeps the latch securely closed and in place.
There are different classifications of rubber latches, including latches which may be made from rubber or other materials, latches with both rubber and metal components, and latches made from just rubber. The various types are designed to meet the needs of an application or set of conditions.

Regardless of which classification it may fall into, each type of rubber latch offers different benefits, such as weather resistance, durability, and ease of use. The specific type of rubber latch used depends on the application and requirements.
As with the manufacture of other rubber products, the manufacture of rubber latches takes several forms with each method designed to produce a latch to fit specific conditions and environments. Additionally, the method of production is dictated by the types of materials, the composition of the latch, and if any coated metals are used.
The process for the production of latches made from solid rubber varies from processes where metal will be coated with rubber or metal components are attached to rubber. It is for these reasons that there are so many different manufacturing and production methods.
Injection molding is a popular method for creating rubber latches because it allows for the production of complex shapes and features. The process involves injecting molten rubber material into a mold, where it cools and solidifies to form the desired shape. The resulting part can then be trimmed, cleaned, and assembled into a complete latch.
This process is similar to compression molding, but allows for greater control over the flow of material, making it well-suited for more complex designs. It can be used with a variety of rubber materials, including silicone, EPDM, and neoprene.
Compression molding is another common method for creating rubber latches. It involves placing a pre-cut piece of rubber material into a heated mold cavity and then applying pressure to compress the material into the desired shape. The part is then allowed to cool and solidify before being removed from the mold.
Liquid injection molding is a process that can create highly precise and detailed rubber components, which could potentially be used for creating rubber latches. The process involves injecting liquid rubber material into a heated mold cavity under high pressure, where it solidifies into the desired shape. This method is best suited for high-volume production runs.
While extrusion is not typically used for creating complete rubber latches, it can be used to create certain components of a latch, such as a seal or gasket. Extrusion involves pushing rubber material through a die to create a continuous length of material with a uniform cross-section.
Overmolding is a process where rubber material is molded over an existing part or substrate to create a rubber coating. This process can be used to create rubber latches that have a hard plastic or metal core for added strength and durability.
Injection molding is used for small, intricate parts, while compression molding is used to create large parts with simple shapes. Transfer molding is used for complex parts that require precise tolerances. Liquid injection molding is ideal for creating parts with high clarity, while extrusion is used for continuous profiles with uniform cross sections. The choice of manufacturing process is very dependent on the use and type of rubber latch.
The term rubber covers a wide range of materials that include natural rubber that is extracted from the rubber tree to synthetic rubbers made from polymers combined with other materials.
