LEP (formerly Mulford Engineering Plastics and Ludowicis) is a national leader in engineered plastics. Large numbers of New Zealand’s manufacturers have relied on their components or production consumables for decades. From injection moulding, polyurethane casting, rubber products and flouropolymers to machined nylons, hdpes or uhmwps, LEP always has the engineered plastic solution required. Since Challenge Partners took over, CNC machining capacity has been doubled and the injection moulding company Pacific Plastics integrated into LEP. More recently, LEP has combined with the leading 3D printing company in the country to complement its own 3D scanning capability.

Masport Foundries Limited is the country’s leading manufacturer of cast ductile and alloy iron. Operating out of its iconic Mt Wellington location, MFL (as it is now known) pours several thousand tonnes annually of high-quality iron castings, most of which are then machined and/or coated prior to final despatch. These are exported globally and MFL products can be found in many areas of Australasian equipment manufacture.
