Our HMPSA machine solutions are complete hot melt pressure sensitive adhesive lines delivered as turnkey systems. They combine stainless steel reactors, high‑torque mixing, inline filtration, vacuum degassing, and pillow, block, or drum packaging. Each line is designed for stable output, repeatable quality, and smooth scale‑up. They support tapes, labels, hygiene, and packaging with clean handling and efficient remelt.
Core Advantages and One‑Stop Service
With 18 years of practice and a 30+ person engineering team, we align robust equipment design with process‑formula guidance. Every line is tailored to your capacity, viscosity window, and pack format. Installation, commissioning, and operator training are included. As an equipment manufacturer with formulation know‑how, we also support PUR, EVA stick, and granular hot melts.
Process Flow & Modules
Reactors for Base Polymer Melting and Blending
Stainless steel vessels provide uniform heating and agitation to melt SIS/SBS and dissolve hydrocarbon tackifiers and oils. Optional vacuum limits air and oxidation to protect color and performance.
Key Specifications — Reactor
Materials: SS316L/SS304 contact surfaces
Capacity range: 500–10,000 L
Heating: thermal oil or electric; 50–220°C
Vacuum: up to −0.095 MPa
Safety: over‑temperature/over‑pressure interlocks
High‑Torque Mixing and Compounding
High‑torque mixers disperse components quickly. Precise speed and temperature control help keep viscosity and tack within target.
Key Specifications — Mixing
Drive power: 50–250 kW (application dependent)
Speed range: 10–120 rpm, vector control
Controls: PLC/HMI with recipe management
Monitoring: temperature, viscosity, torque trending
Filtration and Vacuum Degassing
Multi‑stage inline filters cut gels and protect downstream modules. Vacuum degassing improves clarity and wet‑out for tapes and labels.
Key Specifications — Filtration/Degassing
Filtration: multi‑stage baskets/screens; easy‑clean design
Degassing: vacuum dome with anti‑foam control
Piping: heated transfer lines to prevent skinning
Packaging Options
Choose pillow packs for fast, clean remelt, blocks for handling flexibility, or drum filling for bulk shipments. Automated weighing, sealing, and labeling reduce manual contact and contamination risk.
Key Specifications — Packaging
Formats: pillow, block, drum filling
Accuracy: ±1–2%
Sealing: laminated films; anti‑stick liners
Throughput: matched to line capacity
Automation, Safety, and Cleaning
PLC control, recipe storage, and trend logs streamline operation. Safety interlocks, emergency stops, and lock‑out points support daily protection. Heated transfer and clean‑in‑place options shorten changeovers.
Technical Specifications & Options
Capacity and Throughput
From pilot to production, the range scales without losing consistency. Modular layouts support future expansion with limited downtime.
Temperature and Viscosity Control
Closed‑loop thermal management and optional viscosity monitoring maintain tack stability and balanced peel and shear.
Materials and Contact Surfaces
SS316L with smooth welds promotes clean processing and quick cleaning.
Control and Data
Central HMI provides alarms, batch reports, trend logging, and traceability.
Packaging and Downstream Integration
Pillow packs, blocks, and drums integrate with conveyors, coolers, and labelers to complete the line.
Applications & Use Cases
Tapes and Labels
Produce carton sealing, masking, double‑sided tapes, and label stock with consistent tack and peel across ambient to elevated temperatures.
Hygiene and Medical
Support low‑residual HMPSA and degassed handling to reduce irritation risks on sensitive backings.
Packaging and Bookbinding
Achieve balanced tack and open time for packaging adhesives and bookbinding. Pillow packs enable fast remelt at converters.
Electronics and Automotive
Formulate protective film and automotive tape adhesives with controlled rheology and clean processing.
Installation, Commissioning, and Support
Fast Start‑Up
Pre‑assembled skids, standard utilities, and clear piping accelerate installation and start‑up.
Training and Knowledge Transfer
Operator training and process manuals turn formula intent into repeatable production.
Maintenance and Lifecycle Support
Spare parts access, remote diagnostics, and preventive plans help sustain uptime and manage cost.
Customization & Formulation Assistance
Integrated Formula Guidance
Work with our engineers on polymer ratios, tackifier selection, and process pairing to meet target tack, peel, and shear.
Trials and Pilot Lines
Pilot options support scale‑up validation and packaging trials before full capacity commitments.
Upgrade Paths
Add capacity, new pack formats, or integrate with a PUR or EVA stick line for multi‑product flexibility.
Quality & Compliance Assurance
Materials and Craftsmanship
Certified stainless, precision fabrication, and documented practices support clean processing.
Factory Acceptance and Testing
Thermal and mechanical checks, with optional wet trials, verify mixing, filtration, and packaging before shipment.
Standards and Safety
Built with machinery and electrical protection, including lock‑out and emergency stop for operator safety.
Category Notes and Next Steps
HMPSA adheres by pressure activation without chemical curing, which differs from PUR and EVA systems. Typical feedstocks include SIS/SBS with hydrocarbon tackifiers and oils. Settings balance tack, peel, and shear to match tape, label, hygiene, and film needs. Ready to specify a line or request a quote? Contact us to discuss your hot melt PSA manufacturing goals.
