Fabrication of our hanit® products
Our hanit® products are fabricated using various manufacturing processes. These procedures in detail are:
- Injection Moulding
- Intrusion Moulding
In extrusion, the plasticized mass (melt) is continuously processed through extrusion dies (tools) into semi-finished products.
In this process thin-walled parts can be economically produced in large quantities.
The difference between extrusion and injection moulding is that with injection moulding a finished part “comes out“ discontinuously, whereas with extrusion semi-finished products such as rods, planks, and boards are formed continuously.
The intrusion process is a combination of extrusion and injection moulding. The reclaimed materials are plasticised, filled into mould cavities and then cooled to solidification. Depending on the mould cavity, split or unsplit, the product is either pushed out by the machine or manually removed. By means of intrusion various products with weights of 1 to 200 kg can be realised.
Even during the pressing process the plastics must be heated before shaping. Subsequently, the required volume of plastic material is dosed into a tool and brought into the desired shape by hydraulic pressure action of up to 200 tons. The still warm moulding is then removed from the tool and usually placed in cooling supports to avoid warping. The press method is suitable for producing thin-walled and large-area products.
Thanks to our manufacturing processes we are able to react quickly and flexibly, to even the most diverse customers’ product requirements.
