Casting & moulding service in Dunedin
Casting and moulding reproduces a part multiple times from a master pattern: a silicone mould is made from the original, then resin (or occasionally low-melt metal) is poured into the mould to produce copies — used for small-run production of figurines and collectibles, jewellery, cosplay and prop parts, replacement knobs and fittings, and prototypes that need to be duplicated cheaply once a master exists. You can supply a physical master part, or have a maker who also 3D prints produce one first. Send the part (or its file) plus how many copies you need and the material properties that matter (flexible, rigid, paintable, food-safe, clear). Turnaround includes mould-making time up front (often the slowest step) then a faster per-copy cast time; expect one to two weeks for a new mould plus casting run. Pricing is quoted per job — mould-making is usually the larger cost for a first run, with each subsequent copy much cheaper, so larger quantities bring the per-unit price down.

FAQ
Casting & moulding — common questions
Do I need to supply the master part myself?
Either a physical master or a 3D file works — if you only have a file, ask whether the maker can 3D print the master first, then mould and cast copies from it.
How many copies make casting worthwhile?
Mould-making is a fixed up-front cost, so casting pays off once you need more than a handful of identical parts — ask the maker for a per-unit price at a few different quantities to see where it makes sense versus printing each one individually.
What materials can be cast?
Various resins covering rigid, flexible (like rubber) and clear finishes, and some workshops cast low-melt metals for small decorative parts. Mention what the finished part needs to do — flexed, painted, handled outdoors — so the right material is chosen.
How long does a mould last?
Silicone moulds typically manage tens to low hundreds of pulls before detail degrades, depending on the part's complexity and the resin used — ask the maker for an estimate against your run size.
