ABSTRACT Padang State Polytechnic has been established since 1987 under the name Polytechnic Engineering and then changed its name several times to the management policy by Andalas University then, until now it is independent until now with the name Padang State Polytechnic. The 33-year-old polytechnic of the Padang State Polytechnic establishment must have an icon, symbol and trinkets that have PNP characteristics so that they are easy to recognize and remember. Souvenirs are a form of applying media for promotion and souvenirs for people who already know and come to Padang State Polytechnic. Plastic injection molding machine is a machine used to mold plastics with a basic material in the form of plastic pellets. Plastic injection molding machine is the process of processing plastic material in the form of seeds which are heated until they become liquid and then injected into the molding which then freezes / hardens according to the shape of the mold. The products produced by injection molding machines vary, from electronic tools, automotive tools, home appliances, plastic souvenirs, to tableware. The success of the resulting product is highly dependent on Molding. The plastic injection molding machine has parts, namely the Injection Unit, Molding Unit and Clamping Unit. The Injection Unit and Clamping Unit are the most important parts in the manufacturing process of plastic products where the control operation is executed on the control panel found on the plastic injection molding machine. The control panel on the machine can adjust the amount of clamping pressure, stroke length, plastic volume, and temperature used. The molding unit is the main part of the plastic product manufacturing process. Mold (mold) is a tool / tool used to make products according to the desired design (shape and dimensions). Plastic molding has its respective functions, parts of the mold, namely Cavity and Core, Sprue, Runner and Gate, Undercut. The printing process on a Plastic Molding machine has several stages such as the cutting process, mold safety and machine safety, execution, product check, setting, execution, and final. Materials used in the Plastic Molding process are usually materials that are often used daily and are safe for use by all groups, such as Polyproplene, Polycarbonate, and High Density Poly Ethylene. The product that will be produced from the molding made is a key toy souvenir made of plastic, with a shape like the Padang State Polytechnic logo, measuring 6 cm long, 6 cm wide and 5 mm thick. The test results obtained will be shown through field applications, socialization at the Padang State Polytechnic and writing in national journals are the targets and outputs of this novice lecturer research activity.

The wear of the plastic injection molding machine bore has an effect on the quality of the machine to some extent. In order to pursuit the maximum of comprehensive benefits in plastic molding factory. Its necessary to design economic, efficient, dedicated instrument which measure inner diameter in the machine bore. In this paper, the measurement instrument in the plastic injection molding machine bore uses eddy current sensors non-contact measurement theory and virtual instrument technology, it can measure the degree of wear in the plastic injection molding machine bore easily. The results are processed by Radial Basis Function neural network (RBF) technology and then get the curve by using curve fitting to reduce measurement error. It can show the degree of abrasion in the plastic injection machine bore.

The plastic injection molding is widely used for the manufacturing of complicated-shaped and high value-added products. The plastic injection molding machine is the most important equipment for the industry. This paper focuses on the mold separation (MS) of the injection molding machines. The characteristics of the MS of injection molding machine with different clamping units are systemically analyzed, the five-hinge joint-double toggle clamping unit and the direct hydraulic pressure clamping unit included. The study points out there are several typical differences between the different clamping units. Meanwhile, it shows there is a linear relation between the MS value and the product weight, and explains why the MS signal can be used to control the injection molding process.

Plastic injection molding machine consume high electricity during manufacturing process which can increase carbon emissions indirectly. The research aim is to generate an energy map for plastic injection molding machine. It involved several experimental investigations by having to record the electrical energy consumption of the machine. The results were than analyzed to develop an energy map for plastic injection molding operation. The results revealed effect of different parameter setting towards electrical energy consumption in injection molding. From this energy map, it can be used by the manufacturer in order to determine the optimized setting parameter in injection molding. This in turn will help to reduce the electrical energy in injection molding process. The reduction of electrical energy will not only reduce the manufacturing cost, but it also can help to reduce the carbon emission emitted during the generation of electrical energy at the power plant. Eventually this research will support sustainable manufacturing processes especially in injection molding industries.
