1, material 筒未达 to temperature degree 时, 切勿启动 machine. new electrical hot generally requirements temperature degree to setting value 30 separation rear again as screw 　　

2, 每次停 machine ultra- semi small above, most good 关闭落 material 口并清扫 material inner material, 设置保 temperature 　　

3, 避免异 material material material loss bad screw and material 筒. anti metal sheet/slice and material material 斗, processing recycling material, add upper magnetic property material anti iron and other material 筒. 　　

4, use anti need material inner plastics full melt, screw rear loss bad system parts. 　　

5, screw 空转, slip and other phenomenon. 　　

6, use new plastics 时, material 筒 余 material dry 净. use POM, PVC, PA+GF and other material amount decrease/reduce raw materials degradation, machine rear and use ABS and other water material dry 净. 　　

7, 避免POM and PVC meanwhile mixed material 筒, in melt temperature degree lower will 会发生 reaction formed heavy industrial 事故. 　　

8, melt plastics temperature degree positive also 不断发现熔 melt plastics black spots or color 时, 应检查 screw ring （ 胶圈, 介子） is loss bad.
