Project snapshot: American Red Cross coagulant dispensing machine

Background:  For numerous applications, medical practitioners such as those at the Red Cross utilize absorbent pads for applying coagulants.  For example, in order to decontaminate operating room surfaces or clean blood off of patients, these pads are impregnated with coagulants and are kept sterile, lint-free, soft, and slightly abrasive. 

Prior to approaching Specialty Design, the Red Cross dispensed coagulants onto absorbent pads by hand.  This approach proved to be too slow and the application too inconsistent.  Specialty Design was able to offer a cost-effective solution...

Solution:  We designed and built a special machine that had the following features:

  • Robotic gun movement
  • Pneumatic dispensing guns
  • UHMW bottle tray
  • Stainless/UHMW gauze tray
  • PLC control
  • Alumninum/Lexan guarding

The Red Cross can now produce coagulant pads in one table load at 30 second cycle times.  Furthermore, coagulants are dispensed in a more uniform and consistent fashion.  Not only did our special machine meet the Red Cross' firm expectations for producing a critical product, but the Red Cross informed Specialty Design that the machine has most recently been provided for military use.

Case Study: Dial Index Machining Center for Automotive Industry

Background: 

Die casting company was given a contract from an auto supplier to cast and machine oil pump covers.  Specialty Design was asked to design and build equipment to drill, countersink and deburr under the following tolerance requirements:

  • Hole location: +/- .002"
  • Flatness: .0006"
  • Finish: #16

See Specialty Design's solution below...

Solution: 

Specialty Design worked with client to design and build a machining center to automatically position parts and machine flatness to within .0006" and hole size and locations to within +/- .002" at a high production rate.  To accomplish these requirements, Specialty Design incorporated the following features:

  • Hydraulic powered index unit (within .0005" accuracy)
  • Hydraulic holding fixtures
  • Servo-driven diamond cutters
  • Multi-spindle drill heads, hydraulic powered with electric motors
  • Electrics with PLC and Panelview
