Heat Treatments VAS applies its proprietary annealing processes to materials that can
Benefit from stress relieving. We consistently monitor our annealing ovens
To ensure calibration and cycle repeatability which assures our customers that
Their components will have dimensionally stable and parts with minimal stress.
Machined-in stress can reduce part performance and lead to premature part failure. To prevent machined-in stress, it is important to identify the causes.
PLASTIC BONDING
Solvent Bonding
VAS offers a best in class approach to solvent bonding manifolds. Through a combination of various
Manufacturing process steps, VAS can provide solvent bonded manifolds that can meet our customers
Expectations. VAS employs 100% flow testing of solvent bonded manifolds to ensure flow paths
Are not obstructed using automated test fixtures designed for each customer part.
Transmissive Bonding
Our Transmissive Bonding process can be a great fit for applications where there are new designs
that have features that cannot be delivered through other bonding methods. We have multiple
approaches for applying this proprietary bonding technique and can quickly determine which
approach is suitable for your application.
TTP Bonding (Also known as Diffusion Bonding)
VAS has developed its own proprietary method of bonding multi-layer fluidic and pneumatic manifolds using trade secrets it has solely developed internally. This proprietary method allows for VAS to provide the industry standard ‘macro’ fluidic manifolds as well as true ‘micro’ fluidic assemblies. Our process can produce multi-layer bonded manifolds that can meet the tightest concentricity requirements WITHOUT secondary machining for concentricity improvement.
Ultrasonic Welding
Ultrasonic Welding is the fastest and most cost effective method used today to join and assemble plastic parts and non-ferrous metals. Ultrasonic welding is cost effective and a green technology. Ultrasonic welding eliminates the need to use fasteners, glues and/or solvents.
Ultrasonic Welding can be used to join all rigid thermoplastics, synthetic fabrics and films. Ultrasonic welding uses an acoustic tool called an ultrasonic horn made to match your parts design. Ultrasonic Welding is converted to heat through friction that melts the plastic or metal. The main components of an ultrasonic welding system are the actuator and power supply, converter/booster & ultrasonic horn called the stack, part holding weld fixture/jig.
