帮我翻译一段文字 （英译中）

Question

1. Introduction
Mould making is an important supporting industry because their related products represent more than 70% among the components in consumer products. The high demand for shorter design and manufacturing lead times, good dimensionality and overall quality, and rapid design changes has become the bottlenecks in mould industries [1]. It is a complicated process, and required skilled and experienced mould maker.
Generally, injection moulding is one of the most important polymer processing operations in the plastic industry today. Approximately one-third of all plastics are converted into parts using injection moulding [2]. This is one of the processes that are greatly preferred in manufacturing industry because it can produce complex-shape plastic parts with good dimensional accuracy and very short cycle times [3]. Typical examples are casings and housings of the products such as computer monitor and mobile telephone, which have a thin shell feature. These products tend to become lighter, thinner and smaller. Hence, the internal components of products have to be packed into housing, which has smaller volume. One way to increase the space of housing parts is to reduce the wall thickness. However, the injection moulding operation becomes more difficult as the wall thickness of plastic parts becomes thinner [4]. This is because the significant warpage defect will be appeared. To reduce this significant defect, testing procedure regarding to the effective factors is required.
A thin plate with dimension 120 mm × 50 mm and 1 mm thickness will be produced. It is use for testing on the effective factors to minimize the warpage defect. Firstly, fabricating the plastic injection mould is needed. After that, the mould is going to be assembled on the injection moulding machine. When the thin plates have been produced, they will be used for testing on the effective factors in warpage problem by applying the experimental design of Taguchi method.

1 。前言
[ 1 ].模具制造是一项重要的支柱产业，因为部分消费类产品占它们的相关产品的70 ％以上。这就需要缩短设计和制造的交货时间，良好的维持整体素质，快速的更改设计已成为模具行业中的关键。这是一个复杂的过程，需要熟练和有经验的模具制造商。
[ 2 ]一般来说，在塑料工业加工的今天,聚合物注射成型是一个最重要的加工业。大约有三分之一的塑料转换成部分使用注塑成型 。[ 3 ] 这是一个过程，极大地倾向于制造业，因为它在很短的周期时间内可以生产复杂形状和尺寸精度良好的塑料零件 。[ 4 ]典型的例子是外壳和外壳的产品，如电脑显示器和移动电话，其中有薄壳功能。这些往往成为更轻，更薄，更小的产品。因此，内部元件产品，必须能够装入，然而它体积小。其中一个方法，是以增加内部空间的部分来减少壁厚。然而因为壁厚塑料零件变薄，注塑操作变得更加困难，。这是因为重大翘曲缺陷将会出现。为了减少这一重大缺陷，测试程序方面的影响因素是必要的。
薄薄的板尺寸120毫米× 50毫米和1毫米的厚度将制作。它是用于测试的影响因素，以尽量减少翘曲缺陷。首先，制造的注塑模具是必要的。在此之后，模具将是组装的注塑机。当薄板生产了，他们将被用于测试有效因素的翘曲问题，采用实验设计的田口方法。

模具制造是一项重要的支柱产业，因为它们的相关产品占70 ％以上的部分消费类产品。的高需求缩短设计和制造的交货时间，良好的维和整体素质，快速的设计更改已成为模具行业中的瓶颈[ 1 ] 。这是一个复杂的过程，需要熟练和有经验的模具制造商。

一般来说，注射成型是一个最重要的聚合物加工业务在塑料工业今天。大约有三分之一的塑料转换成部分使用注塑成型[ 2 ] 。这是一个过程，极大地倾向于在制造业，因为它可以产生复杂形状的塑料零件尺寸精度和良好的很短的周期时间[ 3 ] 。典型的例子是外壳和外壳的产品，如电脑显示器和移动电话，其中有薄壳功能。这些产品往往成为更轻，更薄，更小。因此，内部元件的产品，必须装入住房，它体积小。其中一个方法，以增加空间的住房部分是减少壁厚。然而，注塑操作变得更加困难，因为壁厚塑料零件变薄[ 4 ] 。这是因为重大翘曲缺陷将会出现。为了减少这一重大缺陷，测试程序方面的影响因素是必要的。

薄薄的板尺寸120毫米× 50毫米和1毫米的厚度将制作。它是用于测试的影响因素，以尽量减少翘曲缺陷。首先，编造的注塑模具是必要的。在此之后，模具将是组装的注塑机。当薄板生产了，他们将被用于测试的有效因素的翘曲问题，采用实验设计的田口方法。本回答被网友采纳
