We developed our own moulds for making traditional and through-running IN-LINE concrete and reinforced-concrete fishing weights.
Our moulds are 3D printed from durable PETG suitable for repeated casting.
With proper handling and oiling before each use, the mould can be used repeatedly.
Easy casting using commonly available bagged concrete.
We also offer moulds calculated for concrete mixtures containing iron filings.
For weights made from commonly available concrete.
For heavier fishing weights made with iron filings.
When testing our moulds, we used B30 bagged concrete with a maximum aggregate size of 4 mm.
Our reinforced-concrete mould testing used a mixture containing approximately 70% B30 bagged concrete and 30% iron filings. This mixture reached a density of approximately 2700 kg/m³.

Choose a mouldMaking your own fishing weight is easy. Prepare the mould, fill it with the correct mixture and allow it to cure sufficiently.
Before each use, apply release oil or ordinary cooking oil.
Depending on the mould, use standard concrete or the recommended reinforced-concrete mixture.
Once the mixture has cured sufficiently, carefully open the mould and remove the finished weight.
Follow our illustrated guide to learn how to prepare the mould, mix the concrete and make your own weights.
To remove the finished weight easily, the mould must be oiled before every use.
Professional release oils are commonly used. For home casting, ordinary cooking oil can also be used.
Important information about our concrete fishing weight moulds.
Yes. The PETG mould is reusable if handled carefully, cleaned after use and oiled before each casting.
Standard bagged concrete can be used. Our standard-concrete moulds are calculated for a mixture density of approximately 2100 kg/m³. In our tests, we used B30 concrete with a maximum aggregate size of 4 mm.
Yes. We also offer moulds specially calculated for reinforced-concrete mixtures with a density of approximately 2700 kg/m³. In our testing, we used approximately 70% concrete and 30% iron filings.
Yes. We also offer moulds for making through-running IN-LINE concrete fishing weights. During casting, a plastic tube is inserted into the mould; after the concrete cures, it forms a channel through the centre of the finished weight. Browse IN-LINE moulds.
When using a mixture with the recommended density and filling the mould correctly, the finished weight should be close to the stated value. The actual weight may vary slightly depending on the mixture, water content and compaction.
Yes. The mould must be oiled before every use. This is essential for easy removal of the finished concrete weight.
