Constant Heat Sealer

Heavy-duty constant heat sealer engineered for laboratory testing, R&D and quality-control of thermoplastic and laminated materials. Built for repeatable, high-pressure seals, the unit accepts a variety of sealing interfaces — bar sealer, heat platen or custom machined tooling for contour-shaped parts — making it suitable for flat films, bags and formed components.

Key features

• Robust stainless-steel construction with powder-coat finish for clean-room compatibility
• Digital temperature control with solid-state timers for precise, repeatable seals
• Variable timer and pressure regulator with gauge to fine-tune dwell and compression
• Low-pressure safety descent for controlled and safe lowering of the sealing head
• Vacuum nozzle for evacuation applications
• Available in 110 V or 220 V (single phase, 60 Hz) electrical configurations

Available configurations & options

• Seal interfaces: bar sealer, heat platen, or custom machined tooling for contours
• Seal lengths: 20" or 30" models
• Gas flush capability for inert/gas-flush packaging
• Bi-active (dual-action) sealing heads for improved compression control
• Self-contained compressed air system option for remote or mobile setups
• Custom options available for specialized tooling, platen sizes and process integration

Applications

• Laboratory and small-batch production testing of thermoplastic films and laminated materials
• Product development, packaging validation and QA where precise temperature/time/pressure control is required
• High-pressure sealing operations requiring durable construction and reliable repeatability

This heavy-duty constant heat sealer is designed for customers who need precise, configurable sealing performance with options for gas-flush, compressed air, and custom tooling to suit specific laboratory or production requirements.
