Auckland Foundry
Our Story

Built on Craft and Experience

"When a job presents itself, many factors drive the process — but one thing remains constant: the requirement for quality and value for money."

Molten Manufacturing is a small, innovative foundry based in Glendene, Auckland, specialising in non-ferrous castings of a very high quality. We are experienced in various casting methods to suit your needs and are enthusiastic about pushing the boundaries of what casting techniques can achieve.

Most clients arrive with existing patterns and tooling. Others come to us with nothing more than a sketch, a photo, or an idea. Either way, our team has the skill, the equipment, and the willingness to take your project through to a finished result you can depend on.

What sets us apart isn’t just the range of what we can do — it’s the depth of knowledge and hands-on care we bring to every job. Size, complexity, quantity, cost, surface finish and end use all influence the method chosen. Our experience means we’ll tell you straight which approach gives you the best outcome for your budget.

All Under One Roof

Patternmaking, casting, fettling, heat treating and a full art department — everything your project needs, in one place.

Method-Agnostic

We select the right process for your job — not whichever one suits us that day.

Quality Over Volume

Single art piece or long production run — our standards don’t change.

Straight Talking

Shaun prefers a conversation. You’ll always know exactly where your job is at.
