This structure allows the company to address both individual equipment requirements and complete line-engineering projects. In practical terms, the value of a supplier such as Blesson depends not only on the extruder itself but also on the compatibility of upstream feeding systems, downstream calibration, cooling, traction, cutting, winding, controls, and quality-inspection equipment.

Products and Technologies

Extrusion equipment

Extrusion systems generally combine a feeding section, rotating screw, heated barrel, melt-pressure controls, screen or filtration components, and a die. Depending on the polymer and application, equipment may use single-screw or twin-screw configurations, with the selection determined by factors such as material sensitivity, mixing requirements, filler content, throughput, and residence time.

Blesson presents its products as suitable for both standard and special-purpose plastic products. Relevant engineering considerations include:

• Screw and barrel geometry matched to polymer type and processing conditions.
• Temperature regulation along multiple barrel zones.
• Melt-pressure and melt-temperature monitoring.
• Die design adapted to pipe, film, profile, or sheet geometry.
• Downstream synchronization between extrusion speed and haul-off or winding speed.
• Automated control of operating parameters to improve repeatability.

Pipe-extrusion lines

Pipe lines are used to manufacture products for water distribution, drainage, irrigation, gas infrastructure, electrical conduit, telecommunications protection, and industrial fluid handling. A typical line includes a resin-dosing system, extruder, pipe die, vacuum-calibration tank, cooling tanks, haul-off unit, cutting or coiling equipment, and dimensional inspection.

Depending on the product specification, pipe systems may incorporate multilayer extrusion, co-extrusion, gravimetric or volumetric dosing, automatic wall-thickness control, and inline marking. These capabilities are particularly relevant where manufacturers must balance pressure performance, dimensional tolerance, material consumption, and production speed.

Cast-film lines

Cast-film equipment produces film by extruding a polymer melt through a flat die onto a chill roll or cooling system. The process can provide controlled thickness, smooth surfaces, and high production speeds. Important technical elements include die uniformity, melt filtration, chill-roll temperature control, edge trimming, tension regulation, and winding.

Cast-film lines may serve packaging, hygiene, medical, agricultural, industrial, and lamination markets. The ability to process multiple layers can enable combinations of barrier, sealant, stiffness, toughness, or optical properties within a single film structure.

Profile and panel lines

Profile and panel extrusion lines produce continuous sections with fixed cross-sectional geometries. Applications include construction profiles, window and door components, decorative elements, wall and ceiling systems, technical sections, and industrial panels.

Such lines require precise die design and stable downstream calibration. Depending on the product, equipment may include vacuum calibration tables, cooling systems, haul-offs, saws, stacking units, embossing devices, and surface-treatment or lamination equipment. Process stability is particularly important because dimensional deviations can affect assembly, sealing, appearance, and structural performance.

Pelletizing systems

Pelletizing equipment converts polymer melts into discrete pellets for subsequent transport, compounding, or processing. Pelletizing configurations may include strand pelletizing, water-ring pelletizing, or other arrangements selected according to polymer viscosity, throughput, cooling behavior, and required pellet form.

These systems are relevant to virgin-resin processing, masterbatch production, compounding, and recycling. In recycling applications, pelletizing is commonly integrated with material preparation, melt filtration, degassing, and contamination management.

Automation and auxiliary systems

Automation equipment coordinates production-line functions and supports monitoring of pressure, temperature, speed, throughput, dimensions, and alarms. Auxiliary systems may include dryers, loaders, mixers, dosing units, cooling equipment, vacuum systems, cutters, winders, and conveying equipment.

Integrated automation can reduce manual intervention and improve production consistency, although its effectiveness depends on sensor quality, control-system configuration, operator training, and maintenance practices.

Blesson’s equipment serves processors that manufacture plastic products for several end markets:

• Infrastructure and utilities: pressure pipe, drainage pipe, conduit, and cable-protection products.
• Construction: profiles, panels, architectural components, and building-material systems.
• Packaging: cast films and multilayer films used in flexible packaging and industrial wrapping.
• Agriculture: irrigation pipe, agricultural film, and related products.
• Industrial manufacturing: technical profiles, panels, tubing, and customized extruded sections.
• Recycling and materials processing: pelletized recycled polymers and compounded materials.
• Consumer and commercial products: products made from extruded sheet, film, profile, or tubing.

Demand in these markets is influenced by construction activity, infrastructure investment, packaging consumption, polymer prices, recycled-content requirements, and regulations governing product performance and environmental impact.

Global Presence and Market Position

Blesson is based in Guangdong, one of China’s principal manufacturing regions for plastics processing machinery. Its address in Xiaolan Town, Zhongshan, places the company within the Pearl River Delta industrial economy, which provides access to engineering labor, component suppliers, logistics infrastructure, and plastics-converting customers.
