安全膜制造的制约因素

安全装置有广泛的应用领域.

他们被分为两个不同的群体:

  • 破裂盘 
  • 快速开关

These applications entail absolute control of the following parameters:

  • 制造过程的可重复性
  • Consistency of 厚度 tolerances from one shipment to the next
  • 均匀的表面状况
  • 持续的机械性能

Over the years, ROBERT LAMINAGE has become a key player in this booming sector.

累进冲压件的“拱度≤1 mm/m”

A historical customer had for many years been manufacturing complicated parts using simple tools. 它只使用传统邮票. Manufacturing involved eight manual cutting operations to achieve the end result. The quality was there, but the cost price was uncompetitive.

So in partnership with ROBERT LAMINAGE, we completely overhauled the production tooling. This exchange of expertise optimised the manufacturing process down to the smallest detail, from raw materials procurement to reducing the waste level. The combined expertise and know-how led to an innovative, rational and high-performance solution.

结果

  • 优化生产工具的维护
  • 更短的建立时间
  • 生产力的提高
  • 提高工具的可靠性
  • 减少浪费的水平
  • 成品成本除以3
进步的邮票

Progressive 冲压 is a metalworking method which can encompass punching, 冲压, bending and several other ways of modelling metal.

The feed system pushes a metal strip through all the stations of a progressive 冲压 die. Each station performs one or more operations until the part emerges with a perfect finish.

The challenge of this operation lies in the high complexity of the parts. 当邮票长度超过一米时, if the raw material entering the tool is not perfectly straight (camber more than 1 mm/m), 这条带子会阻塞工具.

Other phenomena may also occur in the stamp if the raw material is not regularly shaped, such as formation of filings or also premature tool wear.

在罗伯特·LAMINAGE, we have developed know-how capable of producing material with an camber of less than 1 mm/metre over the entire length of the strip. A unique creative force in the field of cold rolling.

Ultra-flat strip for the chemical etching industry

In a context of shortage of solutions on the market, numerous customers performing chemical etching regularly come to us with the following constraints:

  • 薄带0.008毫米厚的
  • 完美的平
  • 厚度公差+/- 0.001 mm

We have created a cutting-edge process combined with the internal development of a specific production line (roller, 炉, 打平单元), 为了满足这些极端的要求.

We have now become a major player on this booming market, mainly due to the miniaturisation of electronic parts.

Ultra-flat strip for the chemical etching industry

Chemical cutting or industrial etching is a subtractive manufacturing process which consists in using chemical etching baths to eliminate material, in order to create an object with the desired shape. 它主要用于金属.

Chemical etching has applications in the printed circuit boards and semi-conductors manufacturing industries. This process is also used in the aerospace, medical and watchmaking industries.

Stress-relieved material for high-precision parts

During machining of a workpiece, tensions will be released, causing deformation.

Many manufacturers apply retouching or backworking to improve the precision of the finished part. Unfortunately, this comes at a cost, and does not always work.

A material which has undergone work hardening deformation is subjected to internal stresses which are distributed non-homogeneously inside the material. 

The case study provides a perfect illustration of the benefits of great know-how.

  • 材料:Rodur / Durimphy.6358
  • 厚度:0.205 +/- 0.003 mm
  • 宽度:20.00 mm
  • Workpiece cut, forged and then machined on one face.

Our customer could not keep to the flatness tolerance after machining. The material deformed and systematically ended up out of tolerances.
Thanks to a heat treatment specifically developed by ROBERT LAMINAGE, we managed to reduce the deformation and significantly improve the quality of the parts.

用于表盘制造商的无应力材料

When the customer cuts or machines its workpiece, 内部紧张局势将得到缓解, 引起零件变形的.

The shape, alloy and 厚度 of a dial makes cutting a delicate operation. There too, internal tensions may cause deformation, making the parts unusable.

案例研究:减少废物水平

  • 材料:CuNi12Zn24 CW403J
  • 厚度:0.80 mm +/- 0.006
  • 宽度:42.00 mm

If the material is cut into washers and reformed into a strip in order to perform major machining operations, 存在显著的变形风险.

Thanks to a specific straightening/planishing process, we shape the material in order to compensate for the deformation that it will undergo during the cutting operation.
The waste level has been halved, enabling a substantial improvement in productivity.

极端的厚度公差

A hearing aid manufacturer approached us to develop membranes with a vibration to forward the perfect frequency into the patient's brain, 从而改善他们的听力.

一个在医学技术中使用特殊合金的例子

  • 材料:1.4301不锈钢
  • 厚度:0.10 mm +/- 0.001 mm
  • 宽度:20.00 mm
  • 条件:退火

The challenge here was to guarantee an extremely fine 厚度 tolerance with an annealed, i.e. 柔软的材料. We developed a special process to guarantee the metallurgical condition of the raw material on extremely thin surfaces.

For years, ROBERT LAMINAGE has specialised in cold rolling strips with ever greater precision. Guaranteeing extreme 厚度 tolerances on rolled strips requires great experience, 以及生产工具, 自己独特的.

Ultimately, innovation in the medical field is only possible with such a level of precision.
