Precision Cleaning

Part cleanliness is critical in the manufacturing process. To meet this stringent requirement, industries are burdened with costly equipment purchases, rigid environmental regulations, training, and numerous certification requirements.

To help you solve this problem, PTI provides a wide range of precision cleaning methods to choose from, eliminating your need to make expensive and time-consuming investments.

Our trained experts work with you to determine which precision cleaning process is necessary based on your components.

PTI’s Precision Cleaning Applications include:

  • Aerospace (OEM/MRO)
  • Laser Components
  • Heat Exchangers
  • Oxygen
  • Medical Devices
  • Automotive Components
  • Missiles
  • Critical Mission Systems

With PTI’s precision cleaning service, your high-performance, sensitive components will meet the required cleanliness criteria.

Failure to meet these standards can result in part malfunction, leading to disastrous consequences.

Capabilities

Ultrasonic Cleaning is achieved using transducers in or attached to the bottom of a tank to emit and radiate sound waves through the cleaning solution. These sound waves cause millions of microscopic bubbles to form and grow. This process is called CAVITATION. These Ultrasonic Cleaning bubbles then collapse or “implode” releasing enormous amounts of energy. These implosions work in all directions to ultrasonically clean and remove contamination from the work piece.
In Aqueous Immersion cleaning, parts are placed in baskets or suspended by straps in a heated aqueous solution that is agitated by compressed air and pumps. Aqueous Immersion cleaning is the preferred method for parts that require a long soak time or if the parts are too large for ultrasonic tanks. At PTI, we have tanks up to 76″ x 42″ x36″ deep to perform Aqueous Immersion.
Turbulent Flushing is ideal for parts that require cleaning of cored passages and galleries. During Turbulent Flushing, parts are connected by hoses to a re-circulating pumping system. This pumping system is capable of square wave pulsing and is coupled to a filtered solvent tank. The cleaning action of the pulsed square wave pumps can be enhanced by securing the part to a mechanical shaker table to ensure optimal cleanliness during the Turbulent Flushing process.
During Vapor Degreasing, a heat source raises the liquid solvent in a tank to its boiling point. When the solvent boils, it produces hot vapors. The parts are introduced into the vapor and the vapor condenses on the part’s surface. The condensed vapors then dissolve the greases and oils on the part and flush them away.
During High Pressure Spray Washing, filtered aqueous cleaning solutions are sprayed at high pressure (50-2000 psi) inside a Class 1000 cabinet. Our High Pressure Spray Washing cabinets are outfitted with turntables that enable the operator to manipulate the part to reach all surfaces. This type of part cleaning is ideal for components that are too large for Ultrasonic tanks. High Pressure Spray Washing is the most effective part cleaning process for parts that have deep, small diameter holes.

In addition to our well-established precision cleaning and cleanliness testing services in class 1000 clean rooms, PTI now offers assembly service in the same class 1000 environment.

If you already have parts here for precision cleaning, you no longer need to run the risk of having your parts exposed to re-contamination during shipping, storage or mishandling before they reach your clean room for assembly, let us do the assembly and they will never leave a class 1000 environment.

We are capable of assembling components with conventional fasteners using calibrated torque wrenches and arbor presses. We also have very extensive adhesive bonding capabilities.

Our In-House machining coupled with our parametric design software (3-D modeling) capabilities enable us to custom design and build tooling to uniquely mate your parts to all of our processes. We also offer finished machining of Teflon once bonded to your parts.
