1. our plastics and their properties
Plastics are regarded as the most important components of industry worldwide. Meanwhile most products, also due to the currently popular 3D printing, are based on pure plastic material, with even more products containing individual plastic components. Compared to alternative materials, our diverse plastic products offer some advantages. Compared to steel or ceramics, for example, the products made of our plastics are much lighter due to their lower density. Metal lovers often mention the obviously higher strength or strength of steel, for example, at this point. However, due to manufacturing processes such as fiber reinforcement, plastics are now also competitive in terms of durability. In addition, plastic generally has naturally better sliding properties and is not susceptible to corrosion or the formation of verdigris in contact with air and moisture.
The different types of plastics essentially differ in the different requirements of different areas of application. Chemical resistance and maximum continuous service temperature are decisive factors in the decision-making process. We produce standard plastics which can be used up to a maximum temperature of 90°C, while the service temperature of our engineering plastics reaches up to 140°C and our special high-performance plastics can withstand loads of up to 430°C.
2. basic requirement of our plastic processing
Our type of plastics processing essentially consists of the production or manufacturing processes of moulded parts, semi-finished products and the like. Our long-term trading partners from the chemical industry supply the high-quality material in the form of e.g. granulate, powder or plates. With the help of the raw material, our experienced teams manufacture quality products from the respective plastics in the following processes of plastics processing, such as milling or drilling.
3. various processes for professional plastics processing
With regard to plastics processing, our materials are characterised by their extraordinarily good machinability. In principle, it is also possible to machine plastics as a private do-it-yourselfer. Apart from model builders who are experts in milling or drilling, for example, plastics can be machined much more efficiently by professional companies such as our plastics turning shop, thanks to years of experience and far-reaching possibilities.
The processes of plastics processing include some aspects which have to be considered for the different plastics. In the course of plastic processing by means of machining, we process thermoplastic materials by cutting through appropriate milling, drilling, turning, sawing or planing. We produce moulded parts or semi-finished products either in single or series production.
3.1 The primary forming methods of plastics processing
We speak of a primary forming process in plastics processing when we produce solid and geometric bodies from previously formless plastics, such as powders or melts. By this kind of the treatment of plastic, tubes and housing parts are manufactured for example. This process for the processing of corresponding thermoplastics is very popular with us, as this type of shaping of plastic does not require any subsequent processing for the precision of the products and is therefore enormously efficient.
3.2 Machining by injection moulding of plastics
We carry out the process of injection moulding plastic in contact with a plasticizing device for maximum quality. The plastic is heated to melting temperature and injected under high pressure into the cavity of a mould. Before the plastic cools down too much after this machining process, it is first compressed by us and then ejected as a finished moulded part. Our injection moulding process for plastics processing offers both advantages and disadvantages. With this type of processing, we are able to achieve high quantities of plastic products in a relatively short time. On the other hand, this type of plastics processing represents a comparatively high cost factor and is therefore more or less efficient depending on the area of application.
3.3 Extrusion of plastics for the manufacture of sheets and tubes
Extrusion is a type of plastic processing in which our machines first filter the unprocessed plastic within an extruder through a funnel and then guide it into a corresponding cylinder. The plastic is then melted and further compressed. Similar to the injection moulding process, the plastic is then plasticized by us and pressed through a nozzle in contact with a screw. The difference with this type of plastic processing, however, is that our extrusion is a continuous process, while the injection moulding process divides the processing of plastic into individual steps. We use extrusion to produce plastic products such as sheets or pipes.
3.4 Plastics processing by calendering
In this machining process, we bring the plastic into contact with a series of rollers so that the desired material shape is created. Plastic processing by calendering is particularly suitable for the production of foils and fine slabs or floor coverings.
3.5 Rotation moulding of plastics
The moulding of plastics by rotation is also called rotational moulding in our industry. Our aim with this special process is to produce hollow and/or seamless plastic products with high quality properties. Our plastic granulate is first melted and then brought into a rotating form for further processing. Due to the rotation, the plastic is deposited on the inner surfaces of the mould during cooling during the further manufacturing process.
3.6 Joining of plastics by joining processes
In order to permanently connect two plastic components, we use the so-called joining process. Other conventional processes for joining plastics are usually welding or gluing of plastics. However, less common processing methods such as screwing or riveting are also used.
4. fields of application of our plastic products
As already mentioned at the beginning, our plastics are used for products of all kinds. After manufacturing processes, such as turning or drilling plastics, they are also used in a variety of applications. The following is an exemplary list of the areas which benefit from the application of our products:
- Medical technology
- automobile industry
- Sanitary and fittings industry
- playground design
- sports equipment
- gas meter
- heating systems
- painting facilities
