Materials for the development, testing and production of series runs.
Choosing the right material for the development of your prototype is of key importance.
Tell us what kind of product you need and for what purpose. Chemets will advise you what material is best to use and we will make it for you.
4 questions with which we always check to see if the material is suitable for your desired product.
How hard does your prototype or product have to be?
How flexible does your prototype or product have to be?
How important is precision in regard to your prototype or product?
Conductivity, resistance, toughness, temperature resistance, the application of other materials onto the material, etc.
Transparency is important because the client can see what is going on with the material. Most often, transparency is demanded by the client when conducting mechanical tests or the flow of fluids. Transparent materials are used for checking luminosity and achieving diffused light (for example in using the material as a skylight). In doing so, the functionality of the product as well as the geometric suitability can be checked.
Temperature resistant materials are used when the client needs to test temperature loads and limits.
In certain industries (for example in the electrical industry) the test of the breakdown of a material are demanded (CTI index) as well as checking the flammability of a material (standard UL 94, V-O). The client can find out the suitability of a material with safety tests and breakdown tests.
Whenever there is a need for mechanical resistance, materials which exhibit the following characteristics are used: elasticity, tensile strength, hardness and toughness.
The elasticity of a material tells us how much the material can be stretched. The tensile strength (Rm) is the mechanical characteristic of a material defined as the maximum tension that the material can sustain, before irreversible changes occur (deformation or a tear). We work with materials having different types of tensile strength. Hardness is the resistance of a material or rather properties resistant to a change in the form of the material; a hard material is never fragile or soft. A tough material is difficult to break, when in the presence of some external forces.
Elastomeric materials are those which can be stretched with relatively little force. They are also available in FDA approved categories and with differing scales of hardness (30-95 Shore A).
Most often there is demand for rubber pieces (polyurethane rubber).
Polyurethane (also plastic castings and vacuum castings) is a resistant, flexible and durable material. Castings can be painted as desired. It can be used in practically all fields. Polyurethane can be as hard as fibreglass, compressible as foam, resistant like rubber, sticky like glue and as an application it can also offer protection just like a protective coating.
There is more and more demand for skin contact materials and food safe materials – FDA. The greatest requirement for biocompatible materials is in the food industry and in medicine.
The most frequently chosen post working of materials are: painting, sandblasting, sanding, lacquering, galvanising, lathing, CNC-ing, milling and engraving.
