RUBBER DIAPHRAGMS  
The Diaphragms are flexible seals that permits relatively long piston strokes while completely eliminating sliding friction.   

 

Not only rolling diaphragms but also:

 Rubber articles made upon

Production of rubber diaphragms

    
    Rubber on metal or fabric

Progetto Gomma use both injection and compression moulding to carries out all the products on customer's drawing. Shapes and dimensions of the finished product have to be studied and developed compatibly to the maxymum dimensions of the selected moulds.

 

    Required tools

Steel moulds are the bases for the final product. This part of the manufacturing process for new items is vital and have to be specifically agreed with the customer before any other subsequent choice. 

 

    Machines

Mainly injection and compression presses are used in the production process.

 

    Manufacturing process

The study of the main physic and chemical features of the polymer is the starting point of the manufacturing process.  After this studying stage, the right performing mixture of the rough material is to be obteined. When this stage is reached, it's the turn of the injection and pressing in the mould. On closing of the press-machine the pressure and the high temperature developed, make possible the physical-chemical process of the vulcanization which conducts to the extraction of the final product.

 

    Application

Rubber components are mainly employed into mechanical, electromechanical and electronic machines and equipments. Both the elasticity and sealing performances as well as mechanical features of the rubber components are requested to ensure the correct functioning of the machines.

    
    Sectors of applications

- Automotive industry

- Mchanical sector

- Electronics

- Medical apparatus and systems

 

    Selection of rough material

The choice of the type of Rubber is made in cooperation with the customer and it is usually carried out in function of the specific environment whereas the component has to operate.
