The handle strips for drawer compartments can be offered with a choice of extruded aluminum or extruded stainless steel surface. The entire process was newly developed in Michelau within half a year.
 
Fridge Flexibility 
Long a trendsetter on the American market; for the first time refrigerator storage compartments are being fabricated from extruded profiles rather than in an injection molding process. Scherer & Trier has now successfully implemented this solution for a German producer of household appliances. The concept is based on a new modular system with which the width and design of the compartment can be flexibly altered to meet requirements. An innovation that pleases not only the manufacturer but the consumer as well.

We don't just apply our plastics expertise to the benefit of the automobile industry but rather in many other fields too, including the household appliances industry. The development of a modular system for a leading producer's refrigerators presented us with a particularly interesting challenge", recalls Thomas Leipold, responsible Sales Manager at Scherer & Trier.
Now for the first time in our Upper Franconia facilities, the refrigerator storage compartments are made of extruded material instead of polystyrene injected mold parts. Three extruded profiles form the compartment housing onto which two molded parts are attached at the left and right as cover caps. Attached to each other these parts form a compartment that stands out because of its flexibility.

Double flexibility thanks to innovation
The new modular system has two essential advantages. Fabrication with conventional techniques would require an individual injection molding tool for each compartment variation.
  This modular approach permits any number of storage compartment model variations to be made from just two or three profile extruder tools. A feature which is also well received by consumers. Aside from the design freedom permitted by potentially unlimited variations, this new technique means significantly lower tooling costs for the manufacturer. Thomas Leipold estimates the savings to be significant: "Costs are approximately one third of comparable injection molding concepts."

Attractive new design-world
The plastic material used and the fabrication processes implemented make the application of new designs possible for the first time. The transparent polystyrene compartments can now be made distinctive with white, metallic or individually designed elements. The aluminium or stainless steel surface finishes can either be produced with hot-stamping technology or indeed with real metal. Of course, as with predecessors, all materials utilized are food safe.

Practical usage an additional bonus
Yet another feature; metal is worked into the extruded profile to produce adequate rigidity. "Our new technique also has a practical supplementary use", adds Thomas Leipold. "The soft area on the surface of the hollow chamber profile protects against unsightly scratches and is also non-slip." Refrigeration in German households has never been so elegant and cool.
