Customized Perfection: How LUNG CHANG Meets Clients’ Needs with Precision Screws and Barrels

LUNG CHANG: Extrusion & Injection Screws for Different Mixing Designs

LUNG CHANG (Lung Chang Machinery Enterprise Co., Ltd.), founded in 1983, is one of the frontier extruder screws and barrels manufacturers in Taiwan. Thanks to the years of experience and R&D activities, the company already earned a good reputation in the local market and has been escalating its fame in the global market such as the Middle East,  Southeast Asia, specializing in designing, processing and manufacturing screws, barrels and gear boxes for plastic machines.

LUNG CHANG can optimize the design of existing screws based on the current needs of different customers. For example, in the production process of PC materials, issues such as carbonization and insufficient product transparency may arise. Additionally, changes in the mixing ratio of different materials or adjustments to the additive ratios might cause the original screws to become unsuitable for use. LUNG CHANG has extensive experience and technology to help customers solve and improve these issues, and they have received a lot of positive feedback.

The company has a variety of product categories. All types of extruder screws and barrels category is the flagship of LUNG CHANG and it is where the company’s focus stands. Extruder screws and barrels made by the company are suitable for many plastic processing machines as long as having an extruder such as recycling machines, blown film extruders, profile extruders, twin screw extruders, mixing screws, and so on.

Besides, injection molding screws and barrels, extruder gearboxes, and blown film die heads are also the other category of plastic machine parts that the company manufactures.

Customization of Screws and Barrels through Customer Demands and Industry Trends

Following the latest design concepts and customer requirements to manufacture customized screws and barrels is one of the crucial approaches for LUNG CHANG. Nowadays, plastics technologies are changing day by day and the materials become more and more varied. In most cases, we see bio based polymers which are mixed with a certain percentage of organic starch due to government regulations and to achieve a greener world. The change in the materials also requires the upgrades in screws and barrel designs. Because each polymer has its own characteristics such as melt flow index (MFI), stickiness level, etc. To meet the latest customer demands and industry trends, LUNG CHANG also works with the raw material manufacturers to optimize its screws and barrels to these kinds of new polymers.

Another important point in extruder screws and barrel design is to achieve a uniform and clear output through uniformly distributed melting temperature. For these purposes, the company uses Japan made SACM 645 steels (Nitriding steel) which are hardened and processed precisely through cautious progress. At the end, LUNG CHANG provides its customers with high quality and lasting screws and barrels processed with nitride treatment, hard chrome plating and bimetal procedures. The final products are wear-resistant and rust-resistant. Thus, the final customer can ensure the well mixed, evenly heated and pressurized polymers for high quality and uniform plastic materials outputs.
