Engineered Around Your Application

Custom Heat Sealing Systems

Start with what you need to seal or manufacture. Novaseal® engineers the press, tooling, heating, controls and automation around the application.

Custom Heat Sealing Systems are developed for products, seal geometries and manufacturing operations that do not fit a standard machine. The application determines the equipment.

Application First

The Application Determines the Machine

There is no single Custom Heat Sealing System that fits every product or production requirement.

Novaseal starts with the product, material and sealing requirement, then develops the machine around the job. Our engineering team brings nearly 50 years of experience in custom heat sealing, tooling, automation and specialized machinery.

Custom Dies & Sealing Tooling

The Tooling Defines the Seal

Novaseal designs and manufactures sealing dies around the required product geometry, seal width and manufacturing operation. A system may use one die or several interchangeable dies.

Straight dies Curved dies Shaped dies Custom seal widths Patterned seals Knurled seals Perforation seals Valve & nozzle tooling Localized seals Seal-cut Logos & custom hot-stamp text

Tooling can also incorporate release arrangements and application-specific coatings.

Application-Specific Capabilities

Features Engineered Around the Application

Features are incorporated where they improve sealing consistency, production flow, output, handling or changeover. The machine includes what the application benefits from.

Heating Element Diagnostics Detects failure of an individual element in a multi-element heating system, helping prevent unbalanced heat distribution and maintain consistent seals.
Hot-Swap Tooling Allows compatible heated dies to be changed without waiting for complete machine cooldown, reducing changeover from hours to seconds where applicable.
Flange Clamp Supports smooth upper-bar release after the sealing cycle for easier material handling and production flow.
Multiple-Up Tooling 2-up, 4-up, 5-up or other practical configurations can produce multiple finished parts in one machine cycle.
Automated Indexing Advances material or product automatically between sealing operations for more consistent production flow.
Material & Product Handling Handling arrangements can be developed around the material, part geometry and required production sequence.
Custom Automation Repetitive production steps can be integrated where automation improves output, consistency or labor efficiency.
Temperature Control Temperature controls are configured around the heating arrangement and sealing requirements of the application.
Controls & Sequencing Press motion, heating, indexing and automated functions can be coordinated around the required production sequence.

For multiple-up and automated applications, production can be evaluated by parts per cycle, finished output, equipment utilization and cost per finished part—not cycle time alone.

Application Breadth

Built Around the Product or Operation

Custom Heat Sealing Systems are not limited to packaging. In many applications, the sealing operation manufactures the finished product, component or subassembly.

Finished Products

  • Veterinary gloves
  • Ice bags and ice packs
  • Telemetry pouches
  • Medical and specialty products
  • Shaped thermoplastic products

Components & Details

  • Clear flexible windows
  • Patches and reinforcements
  • Hem ends
  • Valves and air nozzles
  • Specialty subassemblies

Specialized Operations

  • Curved and shaped seals
  • Patterned and knurled seals
  • Perforation seals
  • Localized sealing
  • Automated sealing operations

Application Proof

One System. Several Manufacturing Operations.

This application demonstrates how custom tooling and direct-contact heat sealing can perform several operations required to manufacture an actual thermoplastic product, including a knurled patterned seal.

It is one example of the custom-system approach; other systems are configured around their own product and production requirements.

Custom Heat Sealing Experience

Custom Systems Built for Manufacturers Across Industries

Novaseal® has engineered and manufactured Custom Heat Sealing Systems for companies with widely different products and production requirements.

Machine Configuration

Configure the Machine Around the Production Requirement

Structure, orientation, heating, actuation and electrical service are selected independently according to the application.

Floor or Table Mounted

Machine structure is selected around tooling size, work access and production flow.

Horizontal or Vertical Orientation

The sealing operation can be oriented to suit product geometry, handling and production flow.

Top, Bottom or Dual-Surface Heat

Heat is applied from the surface or surfaces best suited to the sealing requirement.

Pneumatic, Electric or Manual Actuation

Actuation is selected according to force, sequence, production rate and application requirements.

Electrical Configuration

Systems are typically 220–240 VAC, with 120 VAC or 480 VAC and single- or three-phase configurations available.

Environment & Finish

Equipment can be configured for industrial or cleanroom environments, with custom finish colors where desired.

Material Capability

Legacy and Sustainable Materials

Custom Heat Sealing Systems can be engineered for a broad range of thermoplastics, films, coated materials and industrial textiles.
