Reka Bentuk Campuran: A well-graded mix is crucial. A common starting ratio is 1 part cement, 4 parts sharp sand, 4 parts coarse aggregate (10-14mm). Water should be added to achieve a semi-dry, moldable consistency—too wet will cause blocks to slump.
The Production Cycle:
- Place a wooden or steel pallet under the mold.
- Fill the mold cavities completely with mix, slightly heaped.
- Engage the vibrator (if equipped) for 5-10 seconds to settle the mix.
- Pull the lever to apply high pressure and compact the block.
- Hold pressure for a few seconds, then release and pull the ejection lever to raise the mold.
- Carefully move the pallet with the fresh blocks to the curing area.
Proses Penyembuhan: Do not move blocks for at least 24 hours. Then, keep them moist and covered with plastic sheeting for a minimum of 7 days to allow proper hydration and strength development. Full strength is achieved after 28 days.

Essential Safety Procedures

Peralatan Perlindungan Diri (PPD): Always wear safety glasses, heavy-duty gloves, steel-toe boots, and a dust mask when handling cement.
Safe Handling: Keep hands clear of moving parts and mold during the compression cycle. Use proper lifting techniques when handling raw materials or blocks.
Workspace: Maintain a clean, organized area free of trip hazards and excess slurry.

Routine Maintenance Checklist

Adhering to a simple schedule prevents major downtime:
* Daily: Thoroughly clean all mold surfaces and the machine frame with water after production to prevent concrete buildup. Check for any visible damage.
* Weekly: Inspect and tighten all bolts and nuts. Lubricate all moving pivot points, levers, and guide rails with light oil or grease as specified.
