Manufacturing Workshop:
We manufacture our own double-layer resin belt flaker by ourselves (Yantai Lingyu Power Machinery Co., Ltd, one of our branch company), the whole production process is controlled automaticlly to ensure stable quality.
New Automatic Packing System is ready now and will be put into production soon, by which time, the whole production process will achieve complete automation. Production efficiency will be improved, meanwhile labor cost will be saved.
Raw Materials:
All the main raw materials are imported from Korea and Japan, like LG Chem, MITSUBISHI, SUMSUNG, HYOSUNG etc. to ensure the high quality of our resins.
Quality Control (Laboratory Detection):
Test & modify formula by professional laboratory reserachers, and improve products' quality to meet customers' various requirements.
