plastic metal detector for injection molding machine

Product Overview

Description

1. Application scope

GMS 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-25~70, processing capacity can reach up to 250kg/hr~1,500kg/hr to meet any specific requirement.

 

2. Features

Standard configuration

1) Fast separating all the metals from the material.

2) Metal detector is adopt Germany brand. 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.

 

Accessory option

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

3. Working Principle

Material discharge pipe has a ring-type metal detector sleeved on and when material with no

metal comes through it, no signal will be sent out from the detector to activate the separating

flap from its standby position. Thus material will flow out via the passage showed in Fig. 1.

 

However when material with metal comes throughit, signal will be sent out from the detector to move the separating flap to the another position. Thus material will flow out via the passage showed in Fig. 2.
