Vacuum Sequencer and Cycle Timer with Vacuum Regulator
The Degassing/Mixing Chamber has a clear Acrylic lid with four latches to maintain the seal while under pressure. The lid has a manual rotary feedthru and handle attached. To the shaft of this feedthru is attached a mixing impeller, sized appropriately for the encapsulant container being used. The chamber accommodates plastic beakers of various sizes. The beakers are held down using three threaded rods with wing nuts and a cover plate. There are two sets of holes, rods and cover plate used for small or large containers
This Controller is designed to be a part of our rugged bench top vacuum chambers in production or testing. Some of our customers find this to be a practical solution for using a vacuum chamber in a controlled process to dry products, and degas of parts, liquids, plastics, resins, and epoxies.
This regulator and cycle controller allows the whole vacuum operation, from start to finish, to be controlled, yielding a more consistaint product process. After set-up, the chamber and vacuum system can automatically turn on the vacuum, watch for the preset vacuum level, then control the hold time at that vacuum level, then break the vacuum to allow the operator to remove and replace product. All this can happen without the operator watching. Your product becomes more consistant and your process more reliable.
Custom features are always an option.
It is constructed of standard industrial parts. Enclosures are for indoor use to provide protection from dust, dirt, and splashing and spraying oil/coolant. Also rated NEMA 13 for protection from oil/coolant dripping. Made of 14-ga. steel (unless noted) with gray powder-coated finish. Enclosures are also known as JIC (Joint Industrial Council) boxes. Covers have a neoprene gasket and secure with a screw clamp on one side. Enclosures are UL listed and CSA certified.
- Degassing/Mixing Chamber
The upper Degassing/Mixing Chamber is a cylindrical chamber (Dimensions: 15” dia x 24” high) in which the one or two-part encapsulating compound is placed. The Vacuum chamber is constructed of heavy Aluminum with a cast Acrylic lid. A customer replaceable O-ring seal is employed to withstand repeated closings. Four draw latches are used to secure the lid to the chamber.The chamber is used to degas and mix the encapsulant under vacuum to eliminate air bubbles. Once mixed, the chamber is pressurized to facilitate flow of the high viscosity encapsulant through the Liquid Feedthru tubes and into the molds in the lower Casting Chamber.The Degassing/Mixing Chamber has a clear Acrylic lid with four latches to maintain the seal while under pressure. The lid has a manual rotary feedthru and handle attached. To the shaft of this feedthru is attached a mixing impeller, sized appropriately for the encapsulant container being used. The chamber accommodates plastic beakers of various sizes. The beakers are held down using three threaded rods with wing nuts and a cover plate
- Casting Chamber
The lower Casting Chamber is a cube-shape chamber (Dimensions: 24” high x 24” wide x 24” deep) in which the molds to be filled under vacuum are placed. The Vacuum chamber is constructed of heavy Stainless Steel 304 with a cast Acrylic door. A customer replaceable O-ring seal is employed to withstand repeated closings. Two draw latches on the right side are used to close the front-hinged door. All chambers are vacuum tested to 29.92 inches of Hg or better (10-7 torr if required) and should maintain this for its life dependent on seal condition and customer use. The chamber is equipped with two removable shelves and associated brackets. The Liquid Feedthru tubes extend into the chamber to be positioned over the molds by the customer.
