模具

A glass die, a micro replication characteristic of PDMS and an electroplating technology are used to make the three-dimensional microelectrode array. A precise cutting machine is used to cut the glass to form a column array and a mixture of HF and NH4F is used to produce the corresponding structure serving as the die of the micro replication of PDMS. The photoetching technology is left out and the limitation of a photoresist on the dimension of the three-dimensional structure is eliminated; therefore the longer microelectrode array can be made. The length of the microelectrode array depends on the incision depth of the glass and the electroplating technology of deep hole of the metal.

本发明利用玻璃模具、PDMS的微复制特性和电镀技术制作三维微电极阵列，用精密切割机切割玻璃形成柱状阵列，用HF和NH 4 F的混合液腐蚀出相应的结构作为PDMS微复制的模具，免去了光刻工艺，消除了光刻胶对三维结构尺寸的限制，可以制作更大长度的微电极阵列，这一长度决定于玻璃的切割深度和金属的深孔电镀技术。

Behind the factory I found a broken plaster mould with a beautiful Chinese decoration which became part of a "leg" as well as a clay pilaster mould.

在工厂后面，我发现了一个坏掉的带有美丽的中国装饰图案的模具，这个图案成为"腿"的一部分，还发现了一个陶泥璧柱模具。

Providing precision, speed and total planarity control, the press is perfect for very large dies and ensures long-lasting performance of all die parts.

应用这种压机可实现精密、快速与完全平面的控制，这种压砖机能很好地应用于很大的模具上，且可以确保模具的所有部件经久耐用。

Minimum mold areas for platen size should always be observed, even in minimum clamp situations.

我们经常看到的是安装尺寸较小的模具（接近最小的模具安装尺寸），然后用最小的合模力。

The restraining effect of Si decreases with decreasing temperature. Fe reduces the chemical potential gradient of the dissolution of iron into molten Al and the driving force of the diffusion of Al into die.

Fe的作用主要是降低模具钢向铝熔体中溶解的化学位梯度和铝向模具中扩散的驱动力，因而，合金中的Si、Fe元素可以降低合金的焊合倾向性。

It is sometimes beneficial to preheat a mold so that production can start with the mold already at its operating temperature.

它有时是有益的预热模具，使生产就可以开始与模具已经在其操作温度。

This tupe of die is often constructed in an inverted position with the punch fastened to the lower portion of the die.

这tupe模具往往是兴建中的一个倒立场与冲床系下的部分模具。
