坯

It is urgent to solve how to produce it efficiently and economically.In this paper, with the guidance of precision forming complex components, basing on the forming theory of obturated-extrusion, combining the technique of hot extrusion, considering the characteristics of steering knuckle, so the one-step precision obturated lateral-bend extrusion forming method and the two-step forming method are presented.

本文以复杂零件的精密成形为指导思想，根据闭塞挤压成形理论，结合热挤压技术，针对轿车转向节零件的自身特点，提出轿车转向节零件的闭塞侧弯挤压精密一步成形法和闭塞侧弯挤压精密预制坯与开式终锻相结合的两步成形法两种工艺。

It was found that the suitable addictive in composites can effectively improve the microstructure, and moreover, prefabricating and sintering technologies are key factors to guarantee the materials with fine microstructure.

认为料坯制备与烧结工艺是保证材料较理想显微组织结构的关键因素。

In the first stage, preforms are made using an injection moulding machine.

第一步用注塑机注出瓶坯。

Preforms have no change in shape and dimension after infiltration thus the near-net-shape products can be achieved.

SiC坯体渗入铝合金后无形状和尺寸的变化，能够实现制品的近净成形。

In addition, the neck (32) of the preforms (30) and bottles (82) is at least partially in the crystalline state and the body (34) is primarily in the amorphous or semi-crystalline state.

此外，型坯(30)和瓶子(82)的颈部(32)至少部分是在结晶状态和主体(34)主要是非晶或半结晶状态。

And the production of PET preforms a variety of specifications.

兼生产各种规格PET瓶坯。

We modified portions of the machine where the preforms and bottles are created, notes Robert Bell, QC's vice president of sales and marketing.

我们修改的部分机器的瓶坯和瓶子的创建，罗伯特贝尔指出，质量的副总裁销售及市场推广。

Injection moulding of bottle caps is distinctly different from that of preforms in that it is thin-wall moulding.

与瓶坯注塑截然不同，瓶盖的注塑是薄壁注塑。

The series could handle 1-litre mineral water bottle preforms from 16 to 48 cavities.

可容纳16腔到48腔一公升的矿泉水瓶瓶坯模具。

By another method, sometimes called jet molding, preforms are charged one at a time into a single-stage plunger machine.

由另一种方法，有时也称为喷射成型，瓶坯的收费是一在一时间成为一个单一阶段柱塞机。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
