The company Lenke Ring Assembly and Machining GmbH has specialized in the operational branches of mechanical engineering and machining production. The design, engineering, manufacturing semi- or fully-automated assembly and test systems are a focus of the company.

Our competence in consulting and manufacturing is built on years of experience as well as modern technology and makes us an estimated development partner for well known companies for engineering and plant construction. Sice the foundation in 1948 Lenser Praezisionstechnik has sucessfully developed into a leading independend provider of heating and cooling plates in Europe. Meanwhile we have been specialized in high precision machining of large metal surfaces for decades.
For decades we have specialized in the production of heating and cooling plates for hydraulic presses. Our experience in this field has made us the leading provider in the European Market independent of the press manufacturer. Such plates are used in the wood-working industry for the production of chips- and fibre boards, for sports equipments as well as for the surface processing of doors, furniture components and timber products.

In the field of laminating and multilayer components such plates are used in card presses and for the production of printed circuit boards. The Rubber goods industry uses our plates for the heating of vulcanising moulds and the production of conveyor belts.

Our heating and cooling plates are exclusively designed product-related on customer request and manufactured as individual units. Our delivery program includes plates of dimensions up to 16.000 mm in length, up to 3.700 mm in width and maximum weights of up to 100 tons per unit.

Our pressing moulds are mainly used by the manufacturers of semi-finished products for the grouting of thermoplastics (e.g. PP, PE, HDPE). They are also used for producing filter elements made of propylene or similar materials.

Indirectly Heated Pressing Moulds

consisting of
– basic plate
– cover plate
– movable frame parts.

Gasic and cover plates are indirectly heated or cooled by the contact heat of heating plates. Frame parts are directly heated or cooled by corresponding mediums.
