The company reports a manufacturing site of about 20,000 square meters and a monthly output of about 20 machine sets on its own land, with exports accounting for a substantial share of sales in company profile material. The same source says the factory has been certified to ISO 9001:2008 and CE requirements.
Products and Technologies
The company’s technical profile is built around modular, co-rotating twin-screw extrusion technology, which is widely used in plastics compounding because it provides strong mixing, dispersion, and formulation flexibility. The company’s “cordwood” modular twin-screw concept, as described on its website, suggests a segment-based screw and barrel architecture that can be configured for different materials and process objectives.
