Reinhard Woltmann

Title: Reinhard Woltmann’s Patented Engineering Work

Introduction

Reinhard Woltmann is an inventor based in Puchheim, Germany. His listed work includes 3 patents focused on casting technology and engine components. He is associated with Bayerische Motoren Werke Aktiengesellschaft, commonly known as BMW.

Latest Patents

One of Woltmann’s listed patents concerns a mold with a feeder channel for casting metals, particularly in low-pressure casting. The design uses a feeder channel clamped between two mold parts at an attachment flange. Its connection to one mold part seals against the mold while leaving an edge area free to expand under heat, helping accommodate thermal expansion.

Another listed patent describes a casting core for an intake pipe assembly in an inline four- to six-cylinder internal combustion engine. Core parts for pairs of similar intake pipes are combined with parts for the intake manifold’s intermediate section to form integral core segments. The segments are permanently joined near their manifold core parts.

Career Highlights

Woltmann’s listed inventions address practical manufacturing challenges in metal casting and the production of engine intake components. His work reflects an engineering focus on mold design, thermal behavior, and the formation of complex internal passages.

Collaborations

Woltmann is associated with BMW. His listed coworkers include Karl Sixt and Jurij Gartner.

Conclusion

Reinhard Woltmann’s patent record highlights contributions to casting molds and intake-system manufacturing, connecting his engineering work with automotive production at BMW.
