This block foaming machine is suitable for producting flexible H.R. rigid, semi-rigid and visco Polyurethane foam blocks - details see: https://www.machineto.com/block-foaming-machine-10338212

The SUNKIST SA-1BM Block Foaming Machine is a newly designed machine for a small to medium scaled production foam factory, and it can fully automatic discontinuously produce rectangular and round blocks, also suitable for the production of flexible H.R. rigid and semi-rigid and visco Polyurethane foam blocks.

Working Principles

SA-1BM Block Foaming Machine consists of mixing system with moving forward and backward device, chemical metering system with re-circulation system to control chemicals which are dosed from the chemical storage tanks through pipe work and pneumatic injection valve systems into the mixing barrel. An adjustable timer controls the mixing time. As soon as the mixing time elapses, the hatch of mixing barrel will auto open to load the mixture smoothly into the mould and close the hatch, then can draw it backward to its original position automatically. To put a level into the mould then after the foam block full rose, mould can be dismantled after moving out the block, then re-assemble the mold box for the next block production. The machine can also add SA-1BVF Vacuum Foaming System conveniently to produce very low density foam block under 10Kgs/cubic meters with decent foaming quality under safe circumstance and can reduce the material cost.

Output Maximum shot weight 150Kgs.

10 blocks or 1.5 tons foam can be produced by 3 operators and 3 mold boxes per hour.

Density between 16 and 50Kgs/cubicmeter is possible to achieve without any difficulty. Feeding Methylene Chloride is advisable for the density less than 13Kgs/cubic meters, working with SA-1BVF for density 8Kgs/cubic meters.

Working range

Maximum size of mold can be fed for rectangular blocks 300cm,width 220cm, and height 125cm.

Maximum size of mould can be fed for cylinder block is diameter 200cm, height 230cm.
