An extruder disc can refer to several different types of devices. The most common one is the small, round, slightly hollowed-out perforated metal plate that is placed at the mouth of a sink or bathtub drain. It acts like a sieve and prevents bits of food or hair from escaping into the drain and clogging it. Another form of extruder disc is the fine mesh that is affixed in front of an extractor fan. This purifies the airflow by trapping the harmful dust or any other fine abrasive particles.
An extruder disc is also used a lot in the creative and precision-driven world of clay modelling.
Giving Shape To Your Design
Clay modelling is all about using moulded clay in various shapes and forms. Thin strands and tubes of clay can be created very easily by expressing the clay through an “extruder”. The extreme end of the tool has a disc with the cut-out of that particular shape, somewhat like a cookie-cutter has. A tool such as this one can be used to cut out plank shapes or brick-shaped blocks of clay and a rectangular mould can be used for this. For tree trunk or column shapes, a circular mould will do the trick. The disc you use will depend on what you are creating. For instance, if you are shaping some jewellery, there is a range of extruder discs you can choose from.
Mentioned below are a few of the commonly-used moulds and their functions:
- When you want to create a scenery with blades of grass and flower stems, what you need is a finely pierced extruder disc also called a screen disc. This same disc can also be used for making fine human hair and animal fur as well as ‘furry fabric’ such as that found on plush animals.
- Woven baskets, bows and ribbons can be made with the use of disc that has a narrow rectangular slot
- In clay models that have buildings or timber, a semicircular shaped disc slot can give you the desired circular shape
- The rectangular and circular-slotted discs are very handy for creating dimensional letters and basic shapes can be created with them
From Colour To Finish
Irrespective of what you are creating, colour is an all-important aspect. Choosing the perfect mix-and-match of colours is what will eventually add that unique touch to the model or jewellery that you make. For this, it is important to understand how different colours work with each other.
Interwoven patterned clay strands make stunning accessories. To obtain perfect results every time, take time to go through a tutorial on baking and varnishing clay products. Clay acquires strength only when it is baked in a furnace and varnishing adds smoothness and gloss to the models you make.
Make It Easy On Yourself
Once you have built up a collection of numerous extruder discs, it is best to make a sample cut from each one of them. Create your own tagging system and label the coordinating sample with the mould that had been used for it. This will help in making your future clay modelling projects easy and you will not have to experiment with shapes and sizes.
