About LEP

About LEP

LEP Engineering Plastics has over 60 years experience in engineering plastics in both Australia and New Zealand – starting originally as Addington Engineering Ltd, then as Ludowici Plastics and recently Mulford Engineering Plastics. The company was purchased by Challenge Partners in 2013 (now Aotearoa Industrial Components Limited) and renamed LEP Engineering Plastics Ltd.

We have extensive manufacturing capacity in our Auckland and Christchurch premises, including a comprehensive polyurethane casting plant in Auckland, an injection moulding factory in Christchurch, plus state-of-the-art machine shops in both Auckland and Christchurch.

In 2014 LEP acquired a 3D plastics printing company Plastic Design Technologies, which has since been rebranded as LEP 3D Printing.
