HMT are one of the country’s leading producers for the plastic components used in bicycle lights, car light clusters and the reflectors used to house the led’s on motorway and railway signs. In these cases tolerances of less than 0.012mm are required to ensure that the parts fit together correctly and reflect light properly.

For the manufacture of LED lights accuracy is particularly important as not only must the units fit together to form the sign but the LED, itself, must fit snugly behind the reflector. Various prototypes were tested before the ultimate design was approved and manufactured. HMT has been involved in the entire process from design to tool-making and finally, production.
