Unit 1 When faced with both economic problems and increasing competition not only from firms in the united states but also from international firms located in other parts of the world, employee and managers now began to ask the question：what do we do now? although this is a fair question, it is difficult to answer. Certainly, for a college student taking business courses or be beginning employee just staring a career, the question is even more difficult to answer. And yet there are still opportunities out there d=for people who are willing to work hard, continue to learn, and possess the ability to adapt to change. 当面对不仅来自美国的公司而且来自位于世界其他地方的国际公司的经济问题和日益激烈的竞争时，员工和经理现在开始要问一个问题：我们要做什么？虽然这是一个很清晰的问题，但是它是很难回答的。当然，对于一个正在谈论商务课程的大学生或者一个刚开始职业生涯的员工来说，这个问题更难回答。但目前仍然有许多机会给那些愿意努力工作，继续学习并且拥有适应变化的能力的人。 Whether you want to obtain part-time employment to pay college and living expense, begin your career as a full –time employee, or start a business, you must bring something to the table that makes you different from the next person . Employee and our capitalistic economic systems are more demanding than ever before. Ask yourself: What can I do that will make employee want to pay me a salary? What skills do I have that employers need? With these questions in mind, we begin with another basic question: Why study business?

《业务营销化》 1 问街上一般的人什么是营销时，他们会告诉你那大概就是“卖东西的”。这从根本上说是正确的，但营销不是简单的销售行为，而是怎样做成的销售。我们都被全天候不间断营销所围绕，而我们每一个人都已经以我们自己的方式成了一名营销人。 2 专家是怎么定义营销的呢？根据美国市场营销协会，市场营销是一种组织职能，是为组织自身及利益相关者（stakeholders n. 利益相关者；股东）而创造、传播、传递客户价值，管理客户关系的一系列过程。 3 根据世界市场营销协会对营销的定义，“核心的经营理念是指导通过交换来识别和满足个人和组织需要的过程，从而为各方创造出众的价值。” 4 最后，英国特许营销学会说，“营销是有利地识别，预测，和满足顾客需求的管理过程”。 5 如果我们只是看这三个定义的共性，我们可以看出，营销本质上（in essence）是：a)发现和给顾客他们所想要的和需要的东西， b)通过做这些来获利。 4Ps或5Ps营销策略 6 密歇根州立大学（Michigan State University）的杰罗姆·麦卡锡（Jerome McCarthy）教授在20世纪50年代写了一本书并且定义了4Ps营销策略，包括产品、渠道、价格和促销。这本书为这个星球上最古老的专业提供了一个清晰的结构，而这个结构成为市场营销的定义。 7 为了更好地理解营销，你应该有你自己对术语的定义。例如，我认为营销是对产品的价格、分配、促销以及人员进行控制，满足顾客以获得利益。控制是个充满感情的词语，尤其在我们谈及控制人的时候。无论怎样，控制是很重要的，因为作为

Optimization of Gate, Runner and Sprue in Two-Plate Family Plastic Injection Mould M.A. Amran*, M. Hadzley, S. Amri, R. Izamshah, A. Hassan,S. Samsi, and K. Shahir Faculty of Manufacturing Engineering, Universiti Teknikal Malaysia (UTeM), Locked Bag 1200, Hang Tuah Jaya, Ayer Keroh, Melaka, Malaysia *Email: mohdamran@https://www.doczj.com/doc/4814453751.html,.my Abstract. This paper describes the optimization size of gate, runner and sprue in two-plate family plastic injection mould. An Electronic Cash Register (ECR) plastic product was used in this study, which there are three components in electronic cast register plastic product consist of top casing, bottom casing and paper holder. The objectives of this paper are to find out the optimum size of gate, runner and sprue, to locate the optimum layout of cavities and to recognize the defect problems due to the wrong size of gate, runner and sprue. Three types of software were used in this study, which Unigraphics software as CAD tool was used to design 3D modeling, Rhinoceros software as post processing tool was used to design gate, runner and sprue and Moldex software as simulation tool was used to analyze the plastic flow. As result, some modifications were made on size of feeding system and location of cavity to eliminate the short- shot, over filling and welding line problems in two-plate family plastic injection mould. Keywords: Computer Modeling; Flow Simulation; Optimization PACS: 07.05Tp 1. INTRODUCTION The plastic injection generally has three phase processes comprising filling, packing and cooling phases. The introduction of simulation software has made a significant impact in the mould making industry with the increasing use of computers in design engineering, the amount of commercially available software on the market has also increased [1]. The ECR plastic product uses same material and colour, however different size of part. Each part has it own mould but on this research, all the parts used family mould. The difficult stage to design family mould is to decide the mould layout, injection location, size of gate, runner, sprue and location of water holes [2], [6], [7]. To investigate the flow behaviour the Moldex software as simulation software was used to analyze the plastic flow. 2.METHODOLOGY This study started from design 3D modeling of ECR product using Unigraphic software and then the files were transferred into Rhinoceros software for post processing. In Rhinoceros software the feeding system such as gates, runners, sprues,waterholes and mould base were designed. Finally, Moldex software is used by importing file from Rhinoceros software. Plastic materials, processing conditions were decided before filling, packing, cooling and warpage analysis. If results do not satisfy, the modification will be done again as shown . 3. DESIGN OF TWO – PLATE MOULD All ECR files consist of top casing, bottom casing and paper holder which they were exported from Unigraphic software to the Rhinoceros software through step one by one. The files were saved under DXF extension which it can be read by Rhinoceros software. Initially, the top casing file was opened in Rhinoceros software which it was converted from solid modeling into mesh modeling as shown in Figure 2(a). Further, Figure 2(b) shows the early stage of imported file of bottom casing from Unigraphic software to Rhinoceros software. The refine mesh of bottom casing has been made until the fine mesh of surface is achieved. The cavity surface was remained after core side had been deleted by removing the mesh. The same method was done for paper holder as shown in Figure 2(c). a b c 3.1 Rectangle Edge Gate Two sizes of rectangular edge gate need to decide which are depth and width. The depth of these parts are calculated using formula h = nt, where h is depth of gate (mm), t is wall section thickness (mm) and n is material constant [3]. Calculation from this formula the depth of top casing and bottom gate are 1.2 mm and paper holder is 1.8 mm. The width of edge gate is derived from equation 1 [4]. W= n x A ? / 30 (1) Where, W is gate width (mm); A is surface area of cavity (mm2 ) and n is material constant. From calculation surface area of top casing is 84,648 mm2 , the width is 5.8 mm. Further calculation, bottom casing width is 5.9 mm and paper holder is 1.27 mm. 3.2 Circular Runner Diameter runner was calculated by taking the weight of part from volume multiply density and distance part from centre of mould as equation 2 [4]. D = W ? x L ? / 30 (2) Where, D is runner diameter, W is part weight and L is distance part to centre mould. Volume of top casing was taken from Rhinoceros software is 78,202 mm3 and the weight is 0.08 kg so the diameter of runner is 6.5 mm. Further calculation, the diameter of bottom casing is 6.7 mm and paper holder is 1.5 mm. 3.3 Sprue The sprue size was decided by taking the thickness cavity plate mouldbase and given angle one degree from diameter 7 mm. Initial cold slug well is 7 mm and base cold slug well is 10 mm. Figure 3 shows the location of top casing, bottom casing and paper holder together with feeding system
