Product overview

Blue Stuff Mold 4 Bars is a reusable hot-water moulding material for copying small parts without measuring or mixing components. Immerse the bars in hot water — Green Stuff World's own instructions say about 65 °C — for 3 minutes, press the softened material over the master, then let it cool before filling the impression. When that mould is no longer needed, reheat the same material and form another. The four-bar pack is the straightforward entry point for press moulds, surface textures and simple shapes; deep undercuts or enclosed forms are better handled with a planned two-part mould.

Soften only what the job needs: Green Stuff World's instructions say to use the amount you need at that moment, so the rest of the pack stays untouched.
The material stays soft longer than the previous formulation, giving it more opportunity to register surface detail.
Use the cooled impression with modelling putties, polyester resin or epoxy resin.
Each bar measures 5.8 × 1.5 × 0.7 cm and weighs 5 g, which is the check to make against the size of the part you want to copy.

Notes · Q & A

Which mould-making material should I choose?

Heat-softened bars suit quick press moulds and simple parts; hand-mixed silicone suits fast detailed impressions; remeltable pour materials suit larger one- or two-part forms. Choose according to the master's undercuts, mould size, casting material, available working window and whether the mould must be reshaped for later jobs.

Can a press mould reproduce deep undercuts?

A one-sided press mould works best where the master and casting have a clear removal path. Deep undercuts, enclosed shapes and detail running around the whole object can trap the part or tear the cast, so they usually need a flexible two-part mould with a planned parting line.

What can I cast, and when is a release agent needed?

Compatibility depends on both the mould material and what is poured or pressed into it. Check the maker's instructions for heat, moisture and cure inhibition; use a suitable release agent when the materials may bond, when a water-based mixture can affect the mould, or between the halves of a two-part mould.

How many times can a reusable mould be used?

There is no universal casting count. Service life depends on the mould material, undercuts, casting heat, cleaning, contamination and how gently parts are removed; heat-softened or remeltable materials may be formed into new moulds, while cured flexible moulds gradually wear or tear.
