Rubber pad forming is an excellent tooling solution for prototyping designs or low-volume production runs. Also called rubber press forming, this process uses hydraulic pressure and rubber pads to press blank sheet metal into desired metal shapes and parts. Rubber pad forming is often used for manufacturing metal diaphragms and components with simple geometries.

Rubber pad forming, or metal-to-rubber forming, is a specialized tooling method for stamping and forming thin sheet metal into specific shapes and precision diaphragms. The main components of a rubber press are rubber pads, which are fitted into a stable steel frame, and a press bed or form block. The form block is machined to the necessary specifications for the desired diaphragms while the rubber pads are standard flat. These components are inserted into a hydraulic press machine, and blank sheet metal is placed between them. Hydraulic operations mold the sheet metal by compressing it between the press bed and the rubber pads.
Also known as metal-to-rubber forming, rubber press forming is primarily for metal diaphragms, although other simple metal components can also be formed. Hudson Technologies uses metal-to-rubber tooling to form parts greater than . inches thick and metal-to-metal tooling for parts less than . inches thick. These presses produce precision metal diaphragms at low tooling and production costs.
At Hudson Technologies, we use two styles of press machines for rubber pressing. Our hydraulic presses can provide both consistent pressure and variable-controlled pressure for different applications, offering flexibility for rubber pressing operations. We operate open-back inclinable gap presses (OBI) to increase metal diaphragm production rates while maintaining quality and precision.
Low tooling and production costs are the main advantages of rubber press forming. Quick-change tooling in metal-to-rubber machines allows for efficient production rates while maintaining precision. Rubber pad forming is most often used for low-volume production runs or testing design ideas.
Additional advantages of rubber press forming for metal stamping processes include:
Rubber pad forming is highly versatile and can press a variety of thin foil metals and materials. While aluminum is one of the most common metals for rubber press forming, additional materials can range from stainless steel and titanium to specialty alloys like Haynes® and Inconel®. When selecting the best metal for a diaphragm project, the team at Hudson Technologies evaluates factors including machinability, weldability, tensile strength, and ductility. Talk to an expert to help determine the right sheet metal for your needs.
While rubber press forming can be used to form a variety of simple geometries, it is most often used to craft precision-shaped metal diaphragms. While these metal components are found in numerous industries, they are predominantly used for aerospace applications. Metal diaphragms formed with metal-to-rubber presses for the aerospace industry can be used for:

In summary, the conversation discusses the use of rubber pads in an application where there is high-speed reciprocating movement between a shaft/piston and a housing. The main goal is to reduce noise and ensure safety. The queries include the appropriate rubber material to use, whether there is a food-grade option, and the major design considerations. Resources are also provided for further information. The conversation also addresses the possibility of using a single, deeper pad for simplicity and effectiveness, but notes that safety requirements necessitate the use of two pads.
The most important factors to consider when selecting a rubber pad include the type of material, the size and shape of the pad, the load and pressure it will be subjected to, and the environmental conditions it will be exposed to.
The choice of rubber material will depend on the specific requirements of the application. Factors such as abrasion resistance, chemical resistance, and temperature resistance should be taken into account. Consulting with a rubber specialist or conducting material testing can help determine the best material for your application.
Yes, rubber pads can be customized to meet the specific requirements of an application. This can include adjusting the size, shape, and material composition of the pad to ensure optimal performance and durability.
The lifespan of a rubber pad will depend on several factors, including the material used, the level of usage, and the environmental conditions it is exposed to. On average, a well-designed and maintained rubber pad can last anywhere from 3-5 years.
To ensure optimal performance from your rubber pad, it is important to choose the appropriate material and design for your specific application. Regular maintenance, such as cleaning and visual inspections, can also help prolong the lifespan and performance of the pad. Additionally, following the manufacturer's recommended load and pressure limits can prevent excessive wear and damage to the pad.
