筛网
钻孔和铣孔技术:开孔率大,质量高
Drilling and milling technology:High stability with a maximum open area

使用电脑控制的轴式钻床,我们可以钻出孔径在 .012'' (0.3mm) 和 .591''(15mm) 的孔,甚至是在最优难度的金属或塑料材料上。
Using our computer-controlled spindle drilling machines we can produce holes with diameters between .012”(0.3mm) and .591”(15mm) even in the most challenging metal or plastic materials.

钻孔比起冲孔有明显的优势:

  • 冲孔时的临界比(最小孔径=板厚=最窄跨梁)在钻孔时可以被打破,使得在厚板上钻出小孔和窄跨梁成为可能。
  •  光滑的孔壁和锥形孔型确保了最佳的过料量,并且无堵塞。
  •  在冲压工艺中可承受高压缩负荷。
  •  可为特定的筛分和过滤场合另外调整孔径,钻孔锥度和开孔率。钻孔筛板的最大优势是较大的开孔率和更好的稳定性。每单位面积内有更多的孔,可增加筛分效率。

通常筛网是决定了一整台设备功效的关键。例如,钻孔网与铣孔结合使用可以优化有纤维悬浮的废水处理,并防止筛网堵料。
Drilling has definite advantage over punching:

  •  The critical ratio observed when punching (smallest hole diameter= plate thickness=narrowest bridge) can be broken , making it possible to produce thick plates with small holes and narrow bridges.
  •  Smooth hole walls and conical hole shapes ensure optimum throughput without plugging the screen .
  •  High compression load during pressing processes.
  •  Individual adjustment of hole diameters,conicity of drilling and the open screening area for specialized sieving and screening applications.

The main advantages of drilled plates are the large open screening area and greater stability.More holes per unit of area improve the screening efficiency.

Often the screen is decisive to the efficiency of a whole plant.For instance,drilled screens used in combination with milled profiles optimize the drainage process for fibrous suspensions and prevent the screen from plugging.

特殊筛分工艺的长条孔网
在某些特定的筛分工艺中,长条孔比圆孔更加合适。比起长条孔,种子,晶体和其他球形工艺处理中更可能堵住圆孔。
长条孔可以达到最细微的宽度。我们提供铣孔网,筛缝宽度最小可达.004'' (0.1mm)。除了各种不同的筛分的横截面形状,如抛物线、梯形,我们还生产异形筛板。
由许多不同材料制作的筛板可以是平的,拢圆的,加工成圆柱、椎体,压力罩或贝壳型。
Slots for special screening processes
Slots are better than round holes for certain screening processes.Seeds,crystals and other spherical process stocks and much more likely to plug a round hole than a slot.
Slots make the tiniest hole widths possible.We supply milled screens with slot widths from .004”(0.1mm).In addition to various slot cross sections,like parabolic or trapezoidal,we also manufacture profiled screening plates.
Plates made of many different
materials will be flat or
rounded,processed to cylinders,cones,press jackets or shells.

高科技穿孔: 激光和电子束技术,最小的筛网开孔
Hi-Tech-Perforation:Laser and electron beam technology for tiny screen openings

激光和电子束技术是机械穿孔技术的绝佳填补,用于需要非常细微的开孔场合。例如,孔径为 .012''(0.3mm) 用于水果和蔬菜榨汁;或者只有 .004'' (0.1mm), 用来从处理废水中回收纤维。
电子束穿孔网是由钢材或其他材料制作的,拥有数百万细微的锥形孔或长条孔。
光滑的表面和锥形的开孔确保了良好的物料过流和很高的筛分效率。
Laser and electron beam technology are an excellent supplement to mechanical perforation methods, applied there,where the tiniest screen openings are required.For instance, hole diameters of .012”(0.3mm) for the extraction of just .004”(0.1mm) to recover fibre from process water.

Beam perforated screens are plates, made of steel or other materials,which have millions of tiny conical holes or slots.

Smooth surfaces and conical openings guarantee good material flow and high efficiency when screening.

多功能细穿孔网
Multi-talented fine perforated plates

ConiPerf® 三角形开孔
三角形开孔是三角形到半椭圆的形状,同样呈现出很明显的锥度。可根据客户需要,通过对三角孔筛网进行轧平,使粗糙不平的表面变得光滑,孔型略微有所变化,但锥度保持不变。
ConiPerf® triangular perforation
The openings of the ConiPerf® triangular perforation have a triangular to half elliptical form,as well as showing a strong conicity.
With rolling of the triangular perforation,the rough surface will be smoothed as requested,producing a slightly changed hole shape but its conicity remains the same.

我们可以在钢板,铝板,不锈钢,黄铜板,铜板,钛板和塑料板上冲孔。通过现代化的自动冲孔,我们可以冲出能想到的任何孔型,未穿孔区-程序-控制-引导,有着准确的重复性和高度的精确性。较小系列或重复单独的订单可以很实惠,因为程序有记忆功能。我们可以提供符合DIN 24 041和ISO标准的标准化筛板,也可以根据您的图纸,制作特殊设计的.016'' (0.4mm) 至 .591'' (15mm) 之间厚度的筛板。
冲孔是金属穿孔中最实惠的一种方法,但是临界比限制了孔径,板厚和最窄跨梁的比例至1:1:1.由于精确的技术,我们的冲孔可以到达网的最边缘。特殊情况下,我们甚至可以降低到临界比以下。对于冲孔无法达到的,我们通过钻孔和铣孔技术来代替。
至于特殊的级别低的和加工订货,我们需要指出的是,我们不生产大批货物,也就是成卷的标准穿孔网。
We punch plates made of steel,aluminum,stainless steel,brass,copper,titanium and plastic.
With modern pinching automation,we are prepared to manufacture almost every conceivable hole pattern,with unperforated areas-program-controlled,with exact repetition and with great precision.
Small series or repeat individual orders can be manufactured economically thanks to the program memory.
We deliver standardized plates in accordance with DIN 24 041 and ISO Standards as well as plates between .016”(0.4mm)and .591”(15mm) thickness in special designs according to your drawings.
Punching is the most inexpensive procedure for the perforation of metals,although the “critical ratio”limits the ratio between hole diameter,plate thickness and narrowest bridge to approximately 1:1:1.Thanks to refined technology,we come very close to the boundaries of that which is possible.In certain cases we can even manage to drop below the”critical ratio”.
We manufacture perforations which cannot be punched,by means of drilling and milling technology.
As specialist for small series and one-off-productions we point out that we do not produce bulk goods,this means standard perforations form the coil.
