Within the plastics machinery sector, GPM is positioned as an equipment supplier serving both conventional extrusion markets and newer high-performance composite applications. Its stated product portfolio spans standard polymer processing platforms such as twin-screw and single-screw extrusion systems, as well as more specialized lines for CFRTP tapes, laminates, honeycomb structures, and composite pipe production. The company states that its extrusion technology originated from France, and that its products have been exported to more than 40 countries and regions.
History and Development
GPM Machinery was founded on 23 May 2011 in Jiading District, Shanghai, where it built its manufacturing base and commercial operations. Over time, the company expanded from conventional extrusion equipment into composite-material production systems, reflecting the broader shift in plastics processing toward lightweighting, higher performance materials, and multi-material engineering.
A second stage of development is visible in the company’s emphasis on CFRTP equipment, including systems for unidirectional tapes, laminate processing, thermoplastic honeycomb panels, and composite pipe production. This indicates a move beyond commodity extrusion lines into higher-value process equipment aligned with automotive lightweighting, energy, and industrial applications.
A third milestone is the company’s stated expansion of manufacturing and service capabilities, including standardized processing and assembly workshops, after-sales support, and a multi-site production footprint in Shanghai, Taicang, and Kunshan, as described in company materials. The company also states that it has been recognized as a high-technology enterprise, a Shanghai “specialized, refined, distinctive, and innovative” enterprise, and a Jiading “little giant” enterprise.
Business Operations and Segments
GPM’s business centers on the design, manufacture, and sale of industrial extrusion and composite processing equipment.
Its operations can be grouped into two broad segments:
- Plastic extrusion machinery for sheet, pipe, profile, roofing, and board production.
- Advanced composite equipment, especially for CFRTP and related thermoplastic composite processing.
The company also states that it has its own import and export rights and sells to international markets, with reported shipments to more than 40 countries and regions across six continents. This export orientation is consistent with the globalized nature of plastics machinery procurement, where processors seek turnkey lines, process know-how, and local service support.
