PUTSCH® is one of the world's largest manufacturers of shear blades for gob feeders. Our products cut over 20 billion gobs of glass a year at glass factories world-wide. Types SM 1775, SM 2316 and SM 4031 are used mainly in the production of glass bottles and glass containers with cutting rates up to 200 cuts per minute. In order for our shear blades to withstand this type of stress, our blades are made of high quality, high speed steel.

For the production of crystal and pressed glasss articles, glass manufacturers mainly use PUTSCH® shear blades type SM 3533, SM 3167 and SM 3299. These blades are made from high precision solid specialty steel in our state-of-the-art machining centers. Shear blades manufactured in this processing manner guarantee superior cutting results and minimal wear and tear.


Optimum Cutting Dynamics

with partial flexibility in the clamping area, combined with the tempered cutting area.

Parallelism and Planimetry

of the cutting edges within tight tolerances offer even, minimal stress on the cutting edges an addition to superioroperating reliability.


Exceptional Durability within minimal Wear and Tear

due to low cutting area pressure.

Special Relief Grinding

of the upper cutting edge avoids shear blade marks.

Various Cutting Edge Angles

for special applications.


Special Tempering

due to the formation of wear resistant carbides.

Excellent Emergency Performance

after temporary thermal overload is an important property of the carbide structure.


Effective Cooling Agent Adhesion

due to the matted shear blade surface allows adjustment of the shear blade temperature for an optimum cutting result.

High Form Stability of Shear Blades under Stress

due to the arrangement of side stamping developed from practical experience.

Regrinding

is possible with high quality PUTSCH® shear blades. The reground blades perform equal to new blades and thus lower the unit cost of the shear blade.


Successfully Meets Individual Customer Request

due to our 130 year experience in the industrial blade production combined with our current, outstanding modern production process.

Quality

PUTSCH® Shear blades are made of high quality, heat resistant special steel. Stringent quality controls are applied to every blade produced. The shear blades in each packaged unit are sorted by height with a ± 1/250 inch (± 0,1 mm).
