Rolls-Royce Limited, Experimental Department, DERBY. Dear Sirs, We are in receipt of your enquiry of the 6th instant for Phosphor Bronze Corrugated Plates. We have gone very carefully into the matter of press tools on this particular job, but in our own opinion it would be too expensive for press tools unless you require quantities of at least 50,000 parts, and even then there would be a certain amount of trial and error in the first place owing to the extra depth. In our opinion this would probably burst, due to the extra depth. If you are only needing a small quantity we are perfectly happy that Spinning would be the cheaper method. If we can be of any further assistance in this matter, we shall be pleased to receive your further comments. Yours faithfully, For CORNERCROFT LIMITED, General Manager. | ||
