Proctor Moulds and Rammers for Soil Compaction Testing

The Proctor Moulds and Rammers are designed for preparing compacted soil specimens during Standard Proctor and Modified Proctor tests to determine the relationship between soil moisture content and maximum dry density.

Each mould assembly consists of a base plate, mould body, and collar, while the Proctor rammers are manufactured with precise weight and drop height in accordance with international testing standards. All components feature a corrosion-resistant electroplated finish for extended service life and reliable laboratory performance.
