Photochemical Etching

Kristeel-Shinwa was established in 1973 in technical collaboration with M/s. Shinwa Rule Co. of Japan, pioneering the process technology of Photo Chemical Machining in India. Today we are the preferred supplier of the thin intricate shapes and custom designed components by Photo Chemical Machining in India.

In our quest of being a leading Chemical Machining Technology Company, we also collaborated with Metal Etching Technology, U.S.A. the leaders for manufacturing world-class chemically-etched / laser cut SMT Stencils and with M/s. Micro Circuit Engineering Corporation, U.S.A. for manufacturing Hybrid and CD Printing Screens.

Our sole objective is to benefit all industries worldwide and in India through this novel technique of photo Chemical Machining, which is the backbone of micro miniaturization.

Our sole objective is to benefit all industries worldwide and in India through this novel technique of photo Chemical Machining, which is the backbone of micro miniaturization.

 

The process of Photo Chemical Machining does seem very simple. However, the expertise comes through the years of research & development and the hard work of our technical personnel.

 

The process of Photo Chemical Machining at Kristeel is a statistically controlled process with a sharp focus on the process capability index at every stage of manufacturing. Our process reliability is supplemented by the state of art manufacturing set-up with Machines imported from U.S.A., Germany and Italy. The class 10,000 Clean Room Dust Free environment is the backbone of manufacturing zero defect Photo Chemically Machined products at Kristeel.

Complete in-house manufacturing facility from designing to finish part at Kristeel speaks of total self-reliance. We have all the requisite infrastructure to offer value-added secondary operations like Bending, Forming, Tumbling for Surface Finish and Plating (Tin, Silver, Gold, Chrome, Blackodising, etc.).

 

Being a technology driven company we are now striving towards the Six Sigma level of operations in all our manufacturing and business processes. We practice the latest management techniques such as Quality Function Deployment (QFD), Failure Mode Effect Analysis (FMEA), Gauge R & R and Design of Experiments (DOE) at various levels to optimize our process for zero defect.

 

With our focus on Six Sigma projects, we have successfully executed in-house projects to increase our process capabilities and enhance productivity throughout the organization.

 

We endeavour to provide our customers with a complete range of reliable technical solutions for their specific requirements.

7 Major Advantages

PCM v/s CONVENTIONAL PROCESS: –
Photo Chemical Machining offers many advantages all of which can be translated into cost savings and better product reliability.

photochem1
LOW-COST TOOLING:

Other processes require elaborate and expensive machine tools. Tooling for Photo Chemical Machining is done primarily through a series of photographic steps reducing tooling costs yet achieving high accuracy. Tooling cost can be as little as 1/10 of that required for other processes, In addition, since there are no cutting tools and therefore no tooling wear (the millionth part is identical to the first), the maintenance cost of tools is eliminated.

photochem2
SPEED OF DELIVERY:

Due to the nature of tooling, the lead time from design approval to finished parts is cut down to only a few days. So, our process can save you time, effort, and money by delivering the parts much faster than any other method.

photochem3
UNLIMITED DESIGN FLEXIBILITY:

Parts whose design is too complex and irregular, and therefore, “impossible or uneconomical” to produce, with standard manufacturing techniques can be produced just as easily, quickly and effectively as simple ones. Thus Photo Chemical Machining provides unlimited design flexibility.

photochem3
INTEGRITY OF METAL PROPERTIES:

The molecular structure of the metal is not affected by our process. No strains or stresses are induced. Furthermore, Photo Chemical Machining does not alter the hardness, grain structure or ductility of the metal worked.

photochem4
TOOLING MODIFICATION:

A change in design means no more than a change in the drawing and film. Design changes are easily made at low cost, saving great losses due to obsolete tooling as in other processes.

photochem5
NO BURRS:

Since blanking is achieved “chemically” rather than mechanically, all finished parts are completely burr-free and as flat as the parent metal from which they are manufactured.

photochem6
PROTOTYPE AND SHORT RUN:

Due to low tooling costs, the design of parts that will eventually be produced by conventional stampings can be produced at a very low cost. This makes Photo Chemical Machining the most suitable method for prototype production and short runs.

Industrial Applications

Potential applications of Photo Chemically Machined products are practically found in most industries to name a few:

  • WASHERS & SHIMS
    The washer is a machine component that is used in conjunction with a screw fastener such as a bolt and nut. Filters are used to remove substances such as dust or dirt. Spacers, Tab Washers & Critical custom made Washers.
  • PHOTOCOPIER & PRINTER COMPONENT PARTS
    Application in Photo Copier machine with or without Graphite Coating & Coro wire. Ribbon Mask for Dot Matrix & High-speed Printers, Ribbon guide, Ribbon Feed Tooth, Washers, Earthing Plates, Solenoid Spacers, Circlips, Stopper and Leaf Armature, Paper Cutter, Leaf Spring, Paper pushing Tab.
  • METAL DIAPHRAGM
    Metal flat diaphragm plates are generally circular plates that deform to subject to pressure or to create a gap between other materials.

  • DECORATIVE / ARTIFACTS
    Decorative Panels, Idols, Book Marks, Certificates, Name Plates, Model Making, Paper / Money Clip, etc.
    – Nameplates
    Nameplates, ON-OFF Plate, Signage, Logo Plates, Instruction Boards, Mark Stencils, Metal Visiting Cards, and Measuring Scales.
    – Gobos
    Over 1,00,000 range of standard designs of Gobos to suit all Events, Occasions, Festivals, Seasons, Windows, Entertainment, Films, Studios, Sports Etc. We also undertake Customized Gobo.
    – Texturing
