Tuopuke 2x4-Inch Pre-Press Mould Anodized 6061 Aluminium — CNC Machined, Hard-Anodized

The TUOPUKE 2x4 Inch Pre Press Mould is an anodized 6061 aluminium tool for forming consistent rectangular pucks (about 7–14 g) before pressing.

Built by CNC machining from aircraft-grade 6061 aluminium and finished with a hard-anodized surface, this 2x4" pre-press mould aims to produce repeatable, clean pucks for downstream pressing or extraction workflows. Its close tolerances and corrosion-resistant anodized coating reduce the chance of the mould binding to the ram and make cleanup straightforward. The rectangular puck shape matches common 3x5 plate kits and works best with 2x4" or 2x4.5" filter bags.

How does the TUOPUKE pre-press mould improve consistency?

Precision CNC machining yields tight dimensional control so each puck is uniform in density and size. A smaller gap between the mould and ram minimizes material shifting and helps the puck hold its shape during transfer to a press or plate. Consistent puck geometry improves heat and pressure distribution later in the process.

• CNC-cut 6061 aluminium body for accurate dimensions
• Hard-anodized interior to resist wear and sticking
• Rectangle 2x4" cavity for uniform puck formation
• Produces 7–14 g pucks ideal for 3x5 plate kits

Will this mould stick or bind while compressing?

The mould uses a hard anodize finish and a reduced tolerance between mould and ram to limit contact-surface adhesion. That combination reduces friction and the risk of the ram getting stuck during repeated cycles. Regular cleaning and light, food-safe lubrication where recommended further lower sticking potential.

• Hard-anodized surface reduces material adhesion
• Smaller ram-to-mold gap prevents jamming
• Easy-to-clean aluminium construction for routine maintenance

What sizes and puck weights does the mould create?

This unit forms a rectangle measuring 2x4 inches and is intended to create pucks weighing roughly 7 to 14 grams depending on tamping pressure and input material volume. That size is compatible with many 3x5 plate setups and pairs well with 2x4" or 2x4.5" filter bags when pre-bagging before pressing. Adjusting fill and compression lets you fine-tune final puck density.

• 2 x 4 inch cavity dimension
• Typical puck weight: 7–14 g
• Designed for use with 2x4" or 2x4.5" filter bags
• Recommended pairing: 3x5 plate press kits for downstream processing

How durable and food-safe is the material?

The mould is machined from 6061 aluminium, a common, corrosion-resistant alloy used in food-contact and industrial parts when properly finished. A hard-anodized coating enhances surface hardness and provides an inert layer that resists oxidation and scratching. With sensible handling it delivers long service life and consistent performance.

• 6061 aluminium core — strong and lightweight
• Hard anodizing for wear resistance and easy cleaning
• CNC precision machining ensures repeatability
• Environmentally friendly finish and recyclable alloy

Who is this for: The TUOPUKE 2x4 Inch Pre Press Mould is aimed at small-batch producers, lab technicians, and home users who want a reliable, repeatable way to form rectangular pucks before mechanical pressing or plate processing. It suits anyone using 3x5 plate systems or 2x4/2x4.5" filter bags and who values consistent puck geometry, durable anodized construction, and a product backed by manufacturer support.
