Enhanced process quality: SEFAR 3A – Stretching clamps


The progressive build-up of the clamping pressure and the lifting function of the SEFAR 3A stretching system enhances its perfor- mance by reducing the reject rate. Why? The mesh can’t slip out the jaws and eliminates friction between fabric and frame.

This means you are able to work with faultless, evenly-stretched screens. Day after day. Another plus point: The SEFAR 3A clamps are suitable for all screen printing mesh – regardless of screen size, materials or thread count. All of this with ease of handling and quick adjustments to the next frame size.

Stretching process safety: Single and dual-circuit Sefar pneumatic systems



The programmable single or dual circuit electronic control unit in combination with SEFAR 3A

For pneumatic stretching systems there are two possibilities to allocate the air supply: Single or dual-circuit systems – complementary alternatives for optimal, balanced tension for all types of mesh and frame sizes. Single-circuit systems are recommended for frames having side lengths up to 150 cm.

For frames having sides longer than 150 cm dual-circuit systems are recommended.
