ASEP-TECH® Systems

Please visit the Product Catalog section of this Virtual Exhibit for more specific information regarding the B/F/S systems mentioned below.

ASEP-TECH® Blow/Fill/Seal machines are designed and manufactured by Weiler Engineering, Inc. in Elgin, Illinois. Our team is dedicated to the highest performance standards in the design and development of Blow/Fill/Seal packaging systems. This unique combination of world-class engineering, leading-edge automation and process design, assures years of reliable, high quality production. The systems consist of Models 603, 624, 628 and 640.

B/F/S Process

The ASEP-TECH® System automatically delivers a finished package in five steps:

1. Thermoplastic resin is extruded into a tubular shape called a parison.

2. When the parison reaches the proper length, the mold is closed and the parison is cut. The bottom of the parison is pinched closed and the top is held in place. The mold is then conveyed to a position under the blowing and filling nozzle.

3. The blow-fill nozzle is lowered into the parison until it forms a seal with the neck of the mold. The container is formed by blowing sterile filtered compressed air into the parison and expanding it against the walls of the integrally cooled mold cavity. Next, the sterile air is vented from the container and the sterile product is metered into the container through the fill nozzle, which then retracts.

4. Separate sealing molds close to form the top and hermetically seal the container.

5. The mold opens, and the formed, filled and sealed container is conveyed out of the machine.

Applications

The ability to provide sterile liquid products that meet corporate, scientific, regulatory and end-user requirements can be a demanding task in today's environment. Through your implementation of ASEP-TECH® Blow/Fill/Seal technology, these application challenges can be met by the creative container and closure designs available with each system. Several machine models are available to choose from, designed to manufacture containers ranging in size from 0.2mL to 1000mL at production rates of up to 15,000 units per hour, depending on container configuration.

Design Services and Prototyping

We offer comprehensive product development, from container/closure concept to complete production tooling ready for your in-house manufacturing on ASEP-TECH® Blow/Fill/Seal machinery. Our skilled craftsmen and designers can develop virtually any container mold through the use of sophisticated CAD/CAM technology and 3-D modeling. These design systems, when interfaced with the latest in CNC and EDM machinery, ensure fabrication of key components to precise tolerances.
