View Technical DataMumbai and its adjoining regions—including Thane, Belapur, Taloja MIDC, and the industrial corridor extending towards Pune—have evolved into prime manufacturing nodes. Traditionally recognized for commerce and textiles, the region now stands as a high-density consumer of thermoformed sheets, technical laminates, and engineering-grade plastic boards. Local demand is driven by the rapid expansion of logistics networks requiring protective packaging, the automotive manufacturing clusters seeking lightweight interior liners, and the booming construction sector looking for reusable concrete shuttering templates.
To sustain competitive margins, plastic processors in Mumbai are shifting from low-capacity, single-layer lines to high-speed co-extrusion technology. Rising raw material costs dictate a need for precise control over scrap reclamation, requiring screw geometries capable of handling up to 70% recycled regrind without compromising tensile properties. Our board extrusion machinery matches this local demand by introducing advanced degassing zones, wear-resistant bimetallic barrels, and closed-loop thickness scanning systems that minimize thickness deviations to under ±1%.

Under the hood of advanced mechanical design, thermal dynamics, and raw material compounding.
The multi-layer co-extrusion process relies heavily on the design of the feed-block and the coat-hanger runner inside the extrusion die. Fluid dynamics analysis (CFD) is employed to simulate polymer flow and avoid interfacial instability between layers of differing viscosities (e.g., virgin ABS capping over recycled HIPS core). Gwell uses micro-adjustable flexible die lips that allow real-time tuning of thickness parameters.
For semi-crystalline plastics (like PP and HDPE) and amorphous plastics (like PC and PMMA), the temperature gradient across the calender rolls determines the mechanical properties and optical clarity of the finished board. Gwell integrates precise internal spiral flow channels within the calender rolls, resulting in a temperature variance of less than ±0.5°C across the entire roll face.
Processing post-consumer or industrial scrap requires highly efficient filtration systems to prevent contamination of the thin capping layer. Our hydraulic non-stop screen changers paired with continuous vacuum degassing (operating at pressures under 0.05 bar) eliminate moisture, volatile compounds, and particulate matter, preventing pinholes and internal structural voids.
