Single Screw Extruder Lab Mini Plastic Extruder Plastic Pipe Line Co-extruding

One of the standout features of the SJ25-28 Lab Mini Plastic Extruder is its precision control system. The extruder is equipped with multiple heating zones along the barrel, allowing for uniform temperature distribution. The temperature of each zone can be individually controlled, ensuring that the polymer reaches the exact processing temperature required for optimal flow. This level of temperature control helps reduce material degradation and ensures the final product meets quality standards.

In addition to temperature control, the SJ25-28 extruder offers adjustable screw speeds and torque settings, providing flexibility to process a wide range of materials. Operators can fine-tune these settings to match the characteristics of specific polymers, giving them full control over the extrusion process. This precision is essential for laboratories and research institutions that require consistent results for experimentation and development.

The SJ25-28 Lab Mini Plastic Extruder is designed to be compact and space-efficient, making it perfect for small-scale production or laboratory environments with limited space. Its small footprint does not compromise on functionality, as it offers the same performance and capabilities as larger extrusion machines. The extruder’s portability makes it easy to move between different research stations or departments, offering maximum flexibility.

Despite its compact size, the extruder is built with high-quality materials and robust construction, ensuring long-term durability and reliability. This makes the SJ25-28 extruder a valuable asset for institutions looking for an efficient and cost-effective extrusion solution for R&D purposes.

The SJ25-28 Lab Mini Plastic Extruder is compatible with a wide variety of thermoplastics, including PVC, PE, PP, PS, and other specialty polymers. This versatility enables users to experiment with different materials, additives, and fillers to create new formulations or optimize existing ones. The extruder can handle various feedstock types, such as pellets, powders, and regrind material, offering flexibility in material selection.

From testing new polymer blends to producing small batches of materials for product development, the SJ25-28 extruder can accommodate a broad range of polymer processing needs. Its ability to handle different types of plastics makes it an invaluable tool for industries involved in plastic material research and development.

The SJ25-28 mini extruder can be equipped with a range of interchangeable dies, enabling users to produce a variety of profiles such as pipes, films, sheets, and rods. This die-swapping feature offers great flexibility for prototyping different shapes and sizes. Whether you are producing standard profiles or creating custom products for testing, the extruder allows for quick and easy die changes, saving time and improving overall production efficiency.

The ability to produce different profiles with minimal downtime makes the SJ25-28 extruder ideal for small-batch production and research purposes, where product variety and experimentation are crucial. This flexibility also makes it a perfect choice for industries that require customized profiles for specific applications.

Once the material enters the barrel, it is subjected to heat from multiple heating zones along the barrel. The heating zones are individually controlled to ensure even and accurate temperature distribution. This helps the polymer to melt evenly and consistently as it moves along the barrel. The screw, in turn, provides mechanical energy to further assist in melting the polymer, mixing it, and preparing it for extrusion.

Temperature control is critical in this stage to avoid material degradation and ensure that the polymer retains its desired properties. The SJ25-28 extruder allows precise temperature control at each zone, giving operators the ability to optimize the extrusion process.

Once the polymer is fully melted and homogenized, it is forced through a die to form the desired profile. The SJ25-28 extruder supports various dies, allowing users to produce pipes, sheets, films, or rods with high precision. The screw speed and extrusion pressure can be adjusted to control the rate at which the polymer exits the die, ensuring the final product meets dimensional specifications.

The ability to swap out dies quickly and easily provides significant flexibility, allowing users to experiment with different shapes and profiles based on their research or production needs.

After the polymer is extruded and shaped, it must be cooled to solidify and retain its profile. The SJ25-28 mini extruder is equipped with an efficient cooling system, which can include water baths or air cooling, depending on the material and profile being produced. The cooling system helps the extruded material solidify quickly while maintaining dimensional stability.

Controlling the cooling rate is essential to achieving the desired mechanical properties in the final product. The SJ25-28 extruder offers flexibility in this regard, allowing users to adjust the cooling rate to suit different polymers and product specifications.

Once the extruded material has cooled and solidified, it is cut into desired lengths using a cutting system. This system can be set up to cut the extrudate into precise lengths based on the needs of the project. The cutting system ensures consistent product dimensions, whether for testing, analysis, or product evaluation.
