A FURTHER stage in the use of the cold .1-1. matched-tool pressing process has been introduced by ERF Engineering Ltd. to produce mouldings for cab front assembly. Using a two-pot system with Bakelite polyester resins, over 1,000 mouldings have been produced in six months, far faster and more cheaply than is possible by conventional hand-laminated processes. Finish is also better.
A feature of these mouldings is the use of threaded metal inserts, located and bonded-in during the process.
Made by: ERF Engineering Ltd., Plastics Division, Biddulph, Stoke-on-Trent.
pRITISH RAILWAYS has devised and patented a new pocket calculator which enables the bulk to weight relationship—and hence the carriage charge—of mainly small items of freight to be determined in seconds. BR says the pocket calculator will be of particular value to transport operators and their customers. Growing use of lightweight materials and new methods of packing have increased the proportion of freight carried which is bulky in relation to its weight. This, it says, has compelled the transport operator to adjust his charges. They now reflect more accurately the cost of providing the space which a consignment occupies. The plastics calculator has a fixed front and back with a movable disc between them. By setting the dimensions of the package in the upper window, the density in Cu. ft. per ton can be read off in the lower window opposite the appropriate weight on the scale. The density of most packages likely to be handled in the sundries category—that is weighing 14 lb. to 2 cwt. and measuring up to 4 ft. in any direction—can be directly calculated from the marked scales. Larger and heavier items would require a further simple sum.
