Really Good Reasons to Purchase from QPS

1. High production by automatic set up and operation by recipe of all of the equipment in the entire System – especially useful for small lot production
2. PLC and PC controls – ease of use and maintenance
3. Robust design including low maintenance features - all Systems ever made except 1 are running three shifts per day. Very high levels of uptime.
4. Precision and repeatability of the parts processed, i.e. hardness, shape, size, surface condition.
5. Special design features:

1. No alloy trays – cost, warped parts, missed locations for loading and unloading.
2. Control of inside and outside quenchant flow – more consistent shape and hardness.
3. Long life of furnace tiles – parts are lifted and set down.
4. No distortion Grippers – does not introduce new problems.
5. Precision Quench Press Operation, control of clamping forces - more consistent parts size and shape.
6. Precision Universal Tooling – can run a range of ring type part sizes and is durable.
7. No water on furnace – reduced fire hazard.
8. No pits in floor – reduced installation costs
9. Some Systems Skid mounted – reduced shipping and installation, can be relocated.
10. Hot run off- assurance of performance.
11. Sometimes no hydraulics – less fire hazard, lower maintenance costs.
12. Custom long life heating elements – fewer replacements and less downtime.
13. Dependable atmosphere system – more consistent parts.

6. Experience

1. A Customer using his 36 inch, two press System reported a reduction in grind cycles from 8 hours to 40 minutes on most of the parts produced.
2. Another Customer producing bearings up to 18 inches is offering his customers completed bearings, shipped in 3 days, from scratch. He cites the following features that allow him to accomplish this:

• The improved roundness and flatness.
• The ability of the equipment to return to previous set- up parameters automatically.
• The repeatability of results.
• The quick changeover of the tooling.
• This system constantly checks that the correct part is being processed.

For example, the Robot grippers measure the size of the part both cold and hot to confirm that it is the correct part. If it is outside the preset parameters, the part will not be run and an alarm presented. This may seem like a bit too much but it would take only one incorrect part to crash the quench press and cause a lot of down time at best and ruin tooling or the quench press at worst. Also the part promised in 3 days would have to be started from scratch again and the promise would not be met.

3. Another Customer can select any of 22 different gears on his 22 lane supply conveyor to be run in any sequence. The system will automatically select the appropriate lane and tooling for maximum "just in time" efficiency on either of the 2 fully automatic Systems installed. This Customer was also able to eliminate all post heat treat finishing with the QPS System and the parts can go directly into his transmissions after cleaning.
4. Another Customer treats a 10.8 inch diameter 0.109 inch thick "driven Disc" for a transmission that achieves a good weight reduction, corrects the shape of the part and accommodates a wide variation in shape from the stamping.
5. One Customer did an energy study and found that the QPS Furnace used so much less energy than similar systems that they did not believe their instruments and repeated the testing with more sophisticated instruments. The QPS System uses less than 20% of the energy that Customer expected based on his experience with many furnaces in multiple factories.
