Hot Air Systems

Hot Boxes are the foundational tool for catheter manufacturing. Our easy-to-use machines allow our customers to achieve maximum performance at a minimal price.   Apply precision heating and delivery using a single or multi-port air nozzle for greater process control, accuracy and repeatability. All models incorporate a self-tuning temperature controller with thermocouple feedback and SCR power control to provide highly stable set-point control. Low heater airflow safety switches are incorporated to prevent heater burnout. These stations perform high quality balloon and tubing bonds, lap joints, tube necking and recovery, bifurcations, trifurcations and more.

The Premium Method of Bonding Balloons

Laser welding machines are used to connect plastic tubing and ideal for welding of balloon catheters. Laser technology guarantees there is no heat effect on the balloon making it the superior technology for balloon bonding applications. The laser enables customers to minimize the length of the balloon leg because the laser can be accurately focused near the balloon without any risk for the balloon seeing heat that would cause damage or pin-holes. Some applications have balloons legs as small as 0.5mm in length and still capable of achieving 24 Bar rated burst pressure. Laser bonder allows for distal bonding and forming of the tip in a single step process. The same laser can be used for both the proximal and distal bonds.

Controlled Compression with Cartridge Heated Dies

Split die thermal bonding machines provide a simple and low-cost solution for a variety of tube bonding applications from R&D to full production.  The split die bonding machine has the ability to perform a wide range of bond widths including highly precise bonds for unique applications such as short balloon bonds and ultra-smooth lap and butt welds.  Heat shrink is typically required to create a smooth transition between the different sizes of tubing.

Applications Include:

  • Butt Welds
  • Lap Welds
  • Balloon Welds

RF Heated Dies

RF bonding applications a stainless-steel die is precisely heated using RF energy.  The stainless-steel dies are sized and designed for each specific application. Heat shrink is not typically utilized for RF applications, but the tooling cannot provide radial compression similar to heatsink. For this reason, RF heated dies are not used for most lap joints, but they are the preferred technology for butt welds. PTFE sleeves can be incorporated into the die to eliminate sticking and increase bond strength.


  • Braid to non-braid butt welds
  • Soft tips (Single step butt weld and tip)
  • Bump (or stepped) dilators
  • Pharmaceutical Rings

Tube Sealers

The SEBRA® line of sealers use RF to make uniform, quality seals on a variety of tubing sizes without power adjustment by the user. Ideally suited for blood and plasma collection, biopharmaceutical and single use manufacturing applications,  RF technology provides a reliable method for processing precious samples, especially those that are temperature sensitive. The seals are easy to visualize and tear, saving you time and reducing discards. Battery powered and bench-top models are available to meet your needs.

Compatible materials include:

  • TPE
  • PVC
  • EVA

10 Ways Expert Device Engineers Create Quality, Repeatable Tube Bonds

Hot Jaw Catheter Bonding

The Hot Jaw Welder is a piece of equipment crafted to fuse plastic tubes. The fusion energy is delivered via electrically warmed clamps while a mandrel stabilizes the internal tube diameter. A shrink tube applies the essential pressure to ensure a secure connection between the tubes during the welding sequence. Key process variables encompass: temperature, duration, mandrel dimension, and clamp magnitude.

An adjustable stopper dictates the accurate position, and pressure on the foot switch pedal activates the welding sequence. The machine has the capability to handle up to three products concurrently.

Braid to Non-Braid Welds

Butt welds are created when two similar sized tubing are bonded together using axial compression. The resulting bond has a smooth OD transition.

Butt welds between braided and non-braided tube segments is a frequent application which is well suited for Vante RF bonding equipment. Strong bonds can be created without allowing metallic braid to become exposed on the outer surface. Heat shrink is not required when using Vante technology, so the bond surface creates a very smooth visual transition between the two tubes. PTFE sleeves can be incorporated into the die to eliminate sticking and increase bond strength.

Learn more about Vante technology and how it is best applied for tube bonding applications.

Overlap Joints Made Easy

Our Hot Air technology is well suited for overlap joints, and in some case thermoplastic butt welds.  With the combination of precise temperature control, a machined thermal nozzle and heat shrink, these systems are capable of yielding high quality overlap joints.  With this proven technology, many customers rely on this equipment to produce high precision, high yield and low-cost solutions for virtually all tube processing needs.  We offer a variety of equipment that is capable of performing numerous foundational catheter manufacturing processes including:

  • Lamination
  • Heat Shrinking
  • Tube to Tube Bonding
  • Catheter Tip Forming
  • Stretching
  • Necking and Flaring

Hot air processes require heat shrink. PET and Silicone heat shrink are some commonly used materials.

Cartridge Heated Die Balloon Bonder

Split die bonding is a two step process involving pre-shrink of the protective sleeve onto the bond area, and contact heat by means of the heated split dies, each featuring half of the bonding diameter.  By comparison, split die bonding offers a lower cycle time than hot air technology due to direct contact of the heated die with the material.  Additionally the split die configuration provides the advantage of being able to visually align the bond location with the heat zone of the dies. These efficient machines are easy to use, easy to calibrate and easy to validate.
