HOW ARE THE DELIVERY DATES IN CASE OF PRODUCTION?

At ETHEN ROHRE we man­u­fac­ture your capillary and precision tubes in cam­paigns for tita­ni­um, stainless steel or nick­el alloys. Tubes of one mate­r­i­al are man­u­fac­tured in pre­vi­ous­ly fixed time inter­vals. For you as a cus­tomer of ETHEN ROHRE this gen­er­ates short­er deliv­ery times and allows exact advance plan­ning. It secures you easy pro­vi­sion, just-in-time or with small own ware­house capacities.

  • Advan­tage 1: You can deter­mine your pro­duc­tion date
  • Advan­tage 2: You pre­serve your liq­uid­i­ty by reduc­tion of inventories
  • Advan­tage 3: You prof­it from short­er deliv­ery times

The ide­al basis is a sup­ply agree­ment guar­an­tee­ing you defined quo­tas. With that you secure your­self pro­duc­tion capac­i­ties at fixed points in time and you can be sure that you will receive your tube sup­ply quo­ta at cal­cu­la­ble deliv­ery dates and con­di­tions, in order to guar­an­tee inter­rup­tion-free pro­duc­tion. You can book cor­re­spond­ing pro­duc­tion slots for our mate­r­i­al cam­paigns tita­ni­um, stainless steel or nick­el, which alter­nate in inter­vals of 9–10 weeks.

The idea behind cam­paign pro­duc­tion for capillary and precision tubes is the com­bi­na­tion of max­i­mum quality and max­i­mum flex­i­bil­i­ty. Test mech­a­nisms, machine tolerances, spe­cial­ized process­es and pro­ce­dures to a great extent depend on the char­ac­ter­is­tics of the materials cur­rent­ly processed. Dur­ing the cor­re­spond­ing cam­paign they remain con­stant and thus pre­vent that adjust­ments lead to ini­tial dif­fi­cul­ties in pro­duc­tion or vari­a­tions in quality. At the same time, cam­paigns tak­ing place in con­tin­u­ous inter­vals nev­er­the­less guar­an­tee short deliv­ery times. “This way we try to com­bine the best from two worlds and feel assured by the pos­i­tive feed­back and increase in the num­ber of our con­tract cus­tomers”, sum­ma­rizes Tobias Kirch, man­ag­ing direc­tor of ETHEN ROHRE.

Of course you can also secure your pro­duc­tion slot with­out a sup­ply agree­ment. Don’t hes­i­tate and ask when your mate­r­i­al cam­paign for capillary and precision tubes is going to start. Con­tact us, if you have any ques­tions on cam­paign plan­ning or you are inter­est­ed in the con­clu­sion of a sup­ply agreement.

HOW CAN I FIND OUT, WHETHER THE TUBES I AM LOOKING FOR ARE IN STOCK?

You can do this eas­i­ly by look­ing at our stock list online. Here you find all avail­able tubes. The list is updat­ed twice a day.

Deliv­ery

CAN I COLLECT MY ARTICLES? WHAT ARE THE COLLECTION TIMES?

Col­lec­tion is pos­si­ble Mon­day to Thurs­day between 12:30 p.m. – 04:30 p.m.

IS IT POSSIBLE TO DELIVER TUBES COILED UP TO A RING?

No, unfor­tu­nate­ly this is not possible.
