Material Processing Solutions--- Five Layer Co-extrusion

There is an overseas funded enterprise group in Guangzhou whose products mainly include plastic and metal fuel tank system. It is a big manufacturer of plastic fuel tank system globally. The enterprise has business in many countries in Europe, America and more than 15 countries in Asia and be a supplier of almost the entire worlds leading car OEMs.

Multilayer material co-extrusion and blow molding makes a high requirement for the surface roughness, hardness, intensity, etc. of its products. Therefore, high quality feeding system, operation and control are claimed.

According to the company’s requirements, a scientific selection based on the multi-angle planning of system configuration has been completed by Shini.

One kind of raw material with a SUS 304 tubes, each layer of raw materials with a powder hopper and a collection hopper, wherein special materials need to be dehumidified and dried before conveying to the corresponding screw. Each Screw corresponding hopper is equipped with a capacitance material level sensor which can accurately detect the material usage condition. SGB series help the system solves the color matching problem.

The control system adopts slandered PLC controller of SIEMENS S7-300 series. And with SIEMENS latest PC control software WINCC V7.0; all signal detection can be transmit to the office so as to realize remote monitoring.
