Metal Injection Molding Process

Machine Automation

USA

Project Introduction:

Metal injection molding is a relatively new process that takes advantage of several key technologies to

produce molded metal parts of various properties. Although driven by the latest technologies in Industrial

Automation, the molding process is very delicate, and if any small pieces are left in the cavity after a part

has been ejected, the mold can be severely damaged during the next cycle. Therefore, our client was

looking to develop an automatic inspection system to monitor the molding process, and prevent severe

damage. Advantech's UNO-2171 was chosen as the control platform for the vision protection system, due

to its Pentium M-grade CPU, fanless architecture, rich I/O support, its USB 2.0, VGA, and LAN ports, and

its overall superior industrial design.

System Requirements:

During the injection molding process, high tempered steel molds are used to form parts into an uncured

(green) state. In some cases, multi-cavity molds for small, very complex orthodontic parts were being

damaged by materials which remain in the mold cavities after ejection. Traditionally, the only way to make

sure the cavities are always clear was to have the operator manually check the cavity after each mold

has been ejected. However, this is a very time consuming and strenuous process for the operator, which

frequently resulted in human error. Not only would the mold and cavities be damaged, but operators

were at risk due to the heated ovens and dangerous machinery. Thus, our customer was eager to find an

automatic mold protection system to prevent damage to their equipment, moldings, and operators.

Advantech's UNO-2171 was chosen as the control platform of the vision protection system. Monitoring

cameras are connected via 2 x USB 2.0 ports, providing VGA output for any 1024 x 768 display. Additionally,

the LAN port was accessed for remote setup, viewing & monitoring. In this fashion, two inspections occur,

once before ejection and once after. This complicated inspection process requires high computing power

which the PC-based UNO-2171 (with Pentium M up to 1.4GHz) meets and exceeds. Moreover, UNO-2171's

industrial features, including its wide operating temperature (-10 ~ 60°C), and anti-vibration and anti-shock

features makes the perfect choice for harsh environments. Furthermore, with its compact size (255 x 152 x

59 mm), the UNO-2171 can be mounted easily in any space-constrained environment.

System Description:

The UNO-2171 is a Pentium M 1.4 GHz Embedded Automation Computer with PC/104 Expansion, and the

ADAM-6060 is an Ethernet-based 6-ch Isolated Digital Input and 6-ch Relay Output module. The automatic

inspection system was designed to integrate UNO-2171, ADAM-6060 and a USB 2.0 CCD camera

together. The UNO-2171 is integrated with ADAM-6060 through Ethernet port, and integrated with USB

camera through USB 2.0 port.

When the mold is open, the limit switch connected to ADAM-6060 will trigger the camera to take a picture.

After image comparison, the ADAM-6060 relay output will send a notice to the injection machine controller

if there is anything inside the mold. After mold ejection, another sensor connected to ADAM-6060 will

trigger the camera to take another picture. After image comparison, the ADAM-6060 relay output will send

a notice to the injection machine controller if there are any foreign pieces inside the mold.

Project Implementation:

Conclusion:

The combination of Advantech's hardware, software, and optical technologies in one product offering provides an extremely

robust, reliable, and affordable technology that can be easily used by non-technical operators. Advantech's UNO-2171 ensures

hi-speed inspections (up to 60 per second), while maintaining 100% accuracy. Our customers not only saves time and labor

costs, but also prevents severe damage, and avoids unnecessary down-time, which can often be more expensive and troubling

than the mold damage itself.
