Welcome to APH Industries Ltd (formerly Lea Manufacturing)

A leading innovator in mechanical polishing.

Our origins of providing high quality finishes for decorative ware led to making precision graded finishes required in the aerospace industry, which in turn helped us to innovate cutting-edge developments to produce a new generation of clean and cost-effective polishing compounds.

Our broad range of products are recognised for their consistent quality and performance, delivering process improvements and consistency for our clients.

We are pleased to let you know we will be changing our trading name from Lea Manufacturing back to our limited company name of the last 40 years; APH Industries Ltd.

Having used Lea Manufacturing as a trading name for 70 years we feel the change reflects the evolution of our product range.

Although renowned for our original Lea Manufacturing brands our company now offers much more abrasive and polishing products and services.

Our dedication to making high quality products and providing excellent service will continue to be at the forefront of our philosophy.
