Extruder device
(Extruder) in the simplest definition, is a machine that makes raw materials (granules or powder) with pressure and heat in the form of a continuous and uniform section. This device is actually responsible for melting, mixing and shaping polymer materials. In any factory where you are dealing with the polymer industry, packaging, or the production of plastic parts, the extruder is the machine that turns amorphous raw materials into final or intermediate products.
Why is it important to choose the right extruder?
The performance of a plastic production line directly depends on the power and precision of the extruder. If your extruder is not compatible with the formulation of the raw materials or the output capacity you want, you will face problems such as product quality loss, material bubbling, or excessive pressure to the electric motor. The correct choice means access to a uniform output, saving electricity consumption and reducing line stop time.
Types of extruders; Which model is suitable for your work?
Categories of extruders are different based on application and operation:
- Single Screw Extruder: The most common type of extruder that is used for simpler processes such as tube, profile and sheet production. These devices have a simpler structure and a more economical price.
- Twin Screw Extruder: With two intertwined spirals, these devices have excellent mixing capabilities. This model is used for mixing additives, masterbatching and recycling of heat-sensitive materials.
- Food Extruder: Designed for sanitary standards (stainless steel) used to produce products such as snacks, puffs and animal feed.
- Laboratory Extruder: Miniaturized versions for research and development (R&D) in factories to test formulations. New.
Key parameters in making and buying an extruder
When ordering the extruder, be sure to check these technical parts so that you don't face the problem of parts failure in the future:
- Ratio of length to diameter (L/D Ratio): This number indicates the length of the spiral compared to its diameter, which has a direct role in the quality of melting and mixing of materials. The higher this ratio, the more accurate thermal control you will have.
- Power transmission system (gearbox): The extruder works under high pressure. Low speed gearboxes with high torque (High Torque) guarantee the life of the machine.
- Type of elements and cooling system: Barrel temperature control at different points must be done with high precision and by PID systems to prevent polymer burning. bimetallic) to be resistant to the wear of impurities.
