Explore Specifications →Over the last decade, Bulgaria has rapidly transformed into a key manufacturing and processing hub for structural polymers within the EU. Supported by strategic industrial locations such as the Trakia Economic Zone (TEZ) in Plovdiv and Sofia’s industrial development parks, the demand for advanced plastic processing machinery has surged. Industrial manufacturers in Bulgaria are seeking to optimize their capabilities by migrating from simple injection moulding setups to complex hollow extrusion lines.
This industrial transition is driven by the European Union’s strict packaging regulations, Green Deal circular directives, and the expanding local automotive packaging sector. Hollow plastic sheets, honeycomb boards, and multi-walled polycarbonate systems are progressively replacing traditional materials like corrugated paperboard, timber, and sheet metals. Local processors require extruders that deliver excellent energy-to-output ratios, strict dimensional control, and robust compatibility with post-consumer recycled (PCR) materials.
Analyzing key advancements in modern extrusion processes, multi-layer co-extrusion technology, and smart calibration systems.
Vacuum calibration plates designed with internal fluid-dynamic simulation software. This ensures uniform cooling, high geometric stability, and minimal internal stress during high-speed continuous operations.
Adapting screw profiles and melt filtration setups to process recycled plastics (rPP, rPET) without compromising the mechanical integrity or load-bearing properties of the finished hollow structures.
Fully integrated PLC control systems monitoring real-time temperatures, melt pressures, gravimetric dosing, and roll-nip positions to maintain close tolerances under fluctuating processing parameters.
Our technical roadmap emphasizes energy-saving barrel induction heating coils and closed-loop water recirculation units. For manufacturers operating in seasonal Bulgarian climates (warm summers, freezing winters), these thermal insulation upgrades cut baseline energy consumption by up to 28% compared to legacy resistance-heated extrusion machinery.

How our extrusion machinery supports industrial manufacturing, modern agriculture, and logistics networks in the Balkan region.
The agricultural regions surrounding Plovdiv and the Thracian valley require durable materials for greenhouse construction. Standard polyethylene films degrade rapidly under UV exposure. High-capacity PC multi-wall hollow sun board extrusion lines address this need. The co-extrusion technology adds online UV-protective layers on both sides of the sheet. This extends the service life of greenhouse structures to over 10 years, improving thermal insulation during winter and lowering energy costs for local growers.
Sofia's logistics hubs and automotive component suppliers require lightweight, durable transit packaging. Single-use cardboard boxes are being replaced by reusable PP hollow board packaging. PP fluted boards produced on GWELL extrusion lines can be folded, washed, and reused hundreds of times. These structural materials are lightweight, moisture-proof, and fully recyclable, helping local manufacturers reduce waste and align with sustainability goals.
Our manufacturing processes and equipment comply with international quality and safety regulations.
Expert answers to common technical queries regarding hollow board extrusion machinery, material processing, and installation.
The mechanical properties of a PP hollow board depend on its structural profile design (cross-rib density and geometry), melt flow indexing, and processing temperature. GWELL extrusion lines feature optimized vacuum calibrators that stabilize the internal ribs during cooling, preventing structural collapse and ensuring uniform compression strength.
Yes. Our screw geometries and barrel heating systems are designed to handle varying levels of post-consumer recycle (PCR) feedstock. We recommend integrating a continuous screen changer and hydraulic melt filtration system to remove impurities, ensuring consistent quality when using recycled materials.
We utilize co-extrusion feedblock technology to apply a thin, uniform UV-protective coating (usually 50 microns) directly onto the outer surface of the PC sheet. This co-extruded layer protects the underlying polycarbonate from yellowing and degradation caused by solar radiation, maintaining light transmission and structural integrity over time.
We provide comprehensive installation, commissioning, and training support. Our engineers assist with factory layout planning, electrical integration, and parameter optimization. Remote diagnostic capabilities and localized technical support ensure reliable operation and minimal downtime for our customers.
