Metal sleeves - Import export

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.

Quicky is a compact precast dowel made from a single piece. Assembling and disassembling parts is not required. Quicky is injection-moulded from high-quality branded HDPE plastic and is therefore cheaper than metal-plastic sleeves. The threadless sleeve allows for the anchoring screw to be turned in and out with an electric screwdriver in seconds. The days of risky unscrewing of threaded parts (breakage!) and cumbersome manual screwing of the anchoring screw into threads that are frequently soiled with cement paste are gone at last!
