Product overview

Blue Stuff Mold 8 Bars provides more reusable material for makers who expect to keep several press moulds active at the same time. Soften as many bars as the job needs in hot water — Green Stuff World gives about 65 °C — for 3 minutes, then press the softened material over the part or texture to be copied. Once the material has cooled, remove the master and fill the resulting impression. Finished moulds can later be reheated and reshaped, so the larger pack reduces the need to dismantle one useful mould before starting another job.

Eight bars in the pack, so several moulds can stay made at once instead of one bar being remelted between jobs.
Green Stuff World states that modelling putty, polyester resin and epoxy resin can be cast into the cooled impression without sticking.
The material stiffens as it cools, so prepare the master and the working area before taking the bars out of the hot water.
Reheating returns an unwanted mould to a soft state for a different part or pattern.
Choose shapes with a clear removal path; pronounced undercuts may lock the original or the casting into a one-sided impression.

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.
