Butyl Rubber Extruder Machine for Sheet and Tape Production Line

It is an extrusion line designed to produce butyl rubber sheets and tapes used as adhesive/sealing tapes, sound insulation and damping materials, automotive door/window/chassis butyl tapes, hollow glass butyl tapes, non-woven and release-paper backed butyl tapes, aluminum foil butyl tapes, waterproof coiled materials, water-swellable strips for tunnels, and (with food-grade specification) chewing-gum base.

Primarily butyl rubber compounds and formulated adhesive blends. It can handle non-woven, release paper, aluminum foil substrates and co-extrude with backing materials. For food applications (chewing-gum base) the machine must be supplied in a food-grade configuration.

Typical specifications include twin or single-screw extruder variants with screw diameters of 75 mm (SJ-75) and 90 mm (SJ-90), L:D ratio 20:1, and motor powers of 30 kW (SJ-75) and 37 kW (SJ-90). Exact line configuration (calendaring, cooling, take-up, slitting) is selectable per application.

Output depends on screw size, die configuration, material formulation and line speed. Rather than a single number, capacity should be estimated from your target tape width/thickness and material density — contact the supplier with product specs for an accurate kg/hr or m/min estimate.

Yes. The line is suitable for water-swellable butyl rubber products used for highway expansion joints and tunnel waterproofing. Formulation and die design are adjusted to ensure the correct cross-section and swelling performance.

It can be adapted for chewing-gum base production, but this requires a food-grade configuration (food-contact stainless steel, appropriate seals, sanitary design) and validation to meet relevant food safety standards. Discuss required certifications with the vendor.

Available options typically include flat-sheet dies, single-lane tape dies, multi-lane tape dies, calendering rolls, cooling tables, embossers, laminators (for foil/non-woven backing), slitters, rewinders, and coating or adhesive application stations. Choice depends on final product format.

Customization can include screw geometry and length, die design and width, heating/cooling systems, line speed, backing/lamination modules (foil, non-woven, release paper), food-grade materials, automation level, and instrumentation for process control or quality inspection.

Manufacturers commonly offer on-site installation and commissioning plus operator and maintenance training. Remote commissioning or factory acceptance testing (FAT) may also be available. Confirm scope, duration and costs with the supplier prior to purchase.

Routine maintenance includes regular cleaning and purging of the screw and barrel to prevent build-up, inspection and replacement of wear parts (screws, barrels, seals), heater and thermocouple checks, gearbox and motor lubrication per schedule, and checking alignment of downstream units. Follow the supplier's maintenance manual for intervals and procedures.

Common issues include inconsistent thickness (check die and roll parallelism, material feed), excessive stickiness or blocking (adjust temperature profile, formulation, and die-clearance; consider release agents), surging or fluctuating output (verify feeder consistency and screw condition), and surface defects (check cooling, die condition and contamination). The supplier can help with detailed troubleshooting.

Yes. Wear parts such as screws, barrels, seals, heater bands, thermocouples and cutting/slitting knives are normally available. It is recommended to keep critical spare parts in stock and order directly from the manufacturer or authorized distributor.

Safety measures typically include emergency stop buttons, guarded moving parts, thermal overload protection for motors and heaters, proper electrical grounding, safety interlocks on access doors, and clear operator controls and labeling. Compliance with local machinery safety regulations is recommended.

Certifications (CE, UL, etc.), warranty terms and lead times vary by manufacturer and order configuration. Typical lead times depend on customization; standard units are faster than fully bespoke lines. Request the vendor's specification sheet for confirmed certification, warranty period and current lead time estimates.

Provide desired end-product specifications (tape/sheet width and thickness, backing type, production rate, material formulation, required certifications). The supplier will use these details to recommend a machine model, line configuration and provide a tailored quotation and expected performance metrics.
