I was able to reduce the missing meat and the inserted burr! I will shape it with a taper and finish the form.
We would like to introduce our cold forging technology, "Improvement of Extruded Forged Gears." In the extrusion forging of helical gears, the tooth profile mold is twisted, causing the pressure during the press extrusion to differ between the upper and lower parts of the mold teeth. The pressure is higher at the top and lower at the bottom, resulting in a twisted shape. As a countermeasure for the shape issue, we set the necessary amount of taper to the mold immediately after extrusion and used this taper for shaping to correct the shape. As a result, the upper and lower surfaces of the gear became rectangular, and the burrs were reduced. 【Technical Overview】 ■ Issue: Twisting of the shape in the extrusion forging of helical gears ■ Countermeasure: Setting the necessary amount of taper to the mold immediately after extrusion ■ Result: Reduced the thickness and the burrs that protrude *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company has always been focused on taking a step forward in building our business. Currently, we are achieving both environmental impact reduction and cost reduction through "cold forging" using a construction method (EDF method) that differs from traditional ones. Cold forging is also a field that requires design capability for molds, so our strength lies in logical manufacturing based on accumulated data, not just experience. Clear Tech makes possible the technologies that no one else has achieved.
