Precision bellows for measurement and control

Thermostatic valves - i.e. the temperature controls on the heating system - are found in just about every home. In the head of a thermostatic valve there is a metal bellows, a corrugated tube that expands according to the room air temperature. For these metal bellows, the manufacturer needed deep-drawn, very long and thin-walled sleeves. The challenge: the sleeves must be matched to the customer's downstream process under very tight tolerance specifications. Why? Because the sleeves cannot be further processed if the geometries vary. Absolute precision is therefore required. We can offer absolute precision. The customer commissioned us with the production of the sleeves. On the one hand, because we fulfil the special deep-drawing requirements. On the other hand, because we can offer an associated, targeted heat treatment for material stress relief in-house.

Special machines from Schmale Maschinenbau are equipped with an intelligent combination of technologies. The plant shown above is used to manufacture reinforcement items from solid material with a diameter of 20mm for the building industry. Servo-electric units such as bending slides, presses and finger benders are combined into customer-specific solutions for the production of individual items that can not be produced on standard machines. Schmale offers special machines for wire, tube and strip processing.
