DPM SOLUTIONS INC.

CUSTOM MACHINED SPECIALIZED EQUIPMENT

2010

Quite a varied few weeks with everything from a small flow cell inside a 3/4” quartz tube to a medium size acrylic solution cell to a large roller calendar.

What’s New at DPM Solutions Inc.

 

 

DPM Solutions is pleased to now be able to offer custom battery testing equipment.

 

 Whether you need test stations for storing multiple cells at a range of temperatures under true open circuit conditions with periodic charge-discharge characterization, or one/many units to store cells under controlled temperatures with connections to an existing cell test station, we will custom design and manufacture a system for you.

CALENDAR ROLLERS

 We’ve recently had two industrial research groups in the United States and a research group from Europe making inquiries about roller presses for battery electrodes.

 Calendaring your electrodes will improve adhesion and increase energy density.

 Do you want improved results?

  Holders for sputtering on the ends of graphite rods.

  

The challenge here was to arrive at a precise and consistent hole size so the holders will keep the rods in place, pushed up against a stop, but still allow easy removal with tweezers.

 

 

  We’ve been making button cell parts from brass and copper so a research group can study the effects of different cell chemistry.  It has been an interesting problem with more to it than first meets the eye.

  

  They look simple - just a little cup to hold the components to build a cell.  

But, when the material is changed to something softer, the thickness has to be increased or the cell will un-crimp itself and the electrolyte will escape.  If the material thickness is increased now either the inside gets smaller or the outside gets bigger.

   

  If the internal diameter is smaller, the cell components won’t fit, if the external diameter is larger then a new cell crimper is required.

PELLET PRESSES

  

Recently we’ve been making hardened and ground pellet presses for the Chemistry Dept. at a Canadian University.  They requested 4 different sizes, one of which was a different style - shown top right of the image beside this text.

  

We have made these in a large range of sizes from about 3/8” to over 2” in imperial or metric sizes.
