From Taipei Plas: Calcium carbonate continues to make inroads in blowmolding

Blowmolders seeking cost savings through reduced material usage in large containers might want to consider the latest coextrusion blowmolding machines from Fong Kee International Machinery Co. (Tainan).

Fong Kee's Wei: Three-layer, calcium-carbonate-filled approach realizes material savings and lower processing costs.

Outlining the latest development at the Taipei Plas show, Fong Kee president Larry Wei said the three-layer machine enables extrusion of a 70% core layer of recycled HDPE filled with 40% calcium carbonate, a 15% inner layer, and a 15% outerlayer incorporating color masterbatch. "Filling with calcium carbonate enables a 20 deg C lower processing temperature, and output is also 20% faster," says Wei. Power consumption is 87 kW/hr at 225 kg/hr output. Up to 144 20-liter jerry cans can be produced each hour. Two machines have already been shipped to Malaysia. Servodrive for the extruders is offered as an option. —mpweditorial@cancom.com
