1.The dangers of  plastic metal impurity:     
     
1) To jam the nozzle of injection molding machine   
2) To damage the screw 
3)To scratch the finished products and leave a mark
4) To block the mould sprue
5) To increase the pressure of hot runner and block the flow
6) To damage mould mirror
7) To bruise precision mould 
8) Mixed the finished with metal, result in unqualified     
     
2.The role of plastic metal impurity separator     
     
1) To protect production equipment
 2) To improve the production efficiency 
 3) To raise the utilization ratio of raw materials
 4) To improve the quality of the products
 5)To reduce equipment maintenance costs and lost production
     
3. Application scope      
     
"SIS series metal detecting separators are highly sensitive and accurate in detecting
and separating metal grains, such as steel, iron, copper, aluminium, lead, tin, and so on. Its principle is when metal impurities pass through it, electrical detector can send a signal to control board to start valve to discharge the impurity materials. Pneumatic discharging system takes little space and ensures good performance. It can be installed directly on injection moulding machine or (extruders) hoppers to protect the screw of machine from the damage caused by hard metals. There are three models of the series: GMS-25~100, processing capacity can reach up to 250kg/hr~2,500kg/hr to meet any specific requirement. The metal separators filter out every piece of metal, right down to the smallest shaving, with extremely reliable results. "   
     
     
2. Features      
     
Standard configuration     
     
1) Fast separating all the metals from the material.
2) Metal detector use metal separator core technology of Germany, The minimum detectable diameter of the metals can be as small as 0.2mm.
3) Compact design, easy to install and simple to operate.
4) Mount directly on injection molding machine or extruder hoppers to protect facilities from the damage caused by hard metals.

     
Specific size of hoppers and floor stands can be customized to meet any requirement.
