      Ten years ago the sale of western high-tech machines to
      the “price-conscious” subcontinent of India was virtually                                Samsonite India Ltd.
      a sensation. Meanwhile, however, India's plastics proc-
      essors are aware of the advantages to be gained by
      quality and productivity: “With Engel machines and hot-
      runner moulds we can now increase productivity by up to
      35% compared with the Taiwanese machines used hither-
      to,” says Rajiv Nath, Joint Managing Director of HMD. The
      following four examples are typical of the applications for
      which Engel machines are being used in India today.
