ABOUT IN-LINE SPRING COILING/TESTING/DETANGLING MACHINERY

What kind of tangled springs can your detanglers separate?

Compression springs are the most common; however other spring designs such as extension and torsion springs are also possible. They all have a tendency to get tangled together. This often results in time consuming and thereby costly manual untangling and sometimes also high scrap rates. Comtech's spring separators are machines developed to solve the problems associated with tangled springs. A Comtech detangling machine eliminates manual separating of springs and thereby increases the user's productivity.

If you have other types of springs or parts that tangle together, COMTECH has many solutions for you. Please contact our sales representative.

Which is the best spring separator for my application?

The size of the springs is the most important factor when deciding which model is best suited for a specific application. By eliminating time-consuming manual untangling of springs, your company will be able to reduce scrap rates, increase productivity and thereby save money.

There are however, other factors that may or may not affect the choice. We always test your springs in order to determine which model is best suited for your application and evaluate the functionality and efficiency. COMTECH recommends sending samples to our facility to be tested in the appropriate machine. COMTECH will ask for feeding rates when applicable along with the samples. We will also ask if you are looking for a manual or automated application, wire specifications and drawings if you cannot provide the samples.

What is involved in the automated spring detangling process?

The automatic spring detanglers and feeders take the detangling process a bit further. Not only do they separate tangled springs, they also allow on-demand delivery of the springs to your assembly.

Another option is our Pick-Up station that lets the operator manually pick springs from the unit one at a time. Each time a spring is picked a 24VDC signal triggers the detangler and sends a new spring to the Pick-Up station.

Another solution is our Pen Dispenser which in a similar manner lets the operator use a pen resembling unit to mount the springs in the end product. Every time the button on the pen is pressed the detangler is triggered to deliver a spring through the Pen Dispenser. This unit is especially suitable when manually assembling small springs into holes. These accessories (Pick-up station and Pen Dispenser) are available also with spring coiling machinery.

Can your detanglers detangle anything other than springs?

Yes, we have many customers who are separating pins, clips, rings and various other parts.

Do the detangling machines only work on metal springs and parts?

No, in fact certain plastics and rubber materials can be easily separated using our detanglers. Once COMTECH receives sample parts, we can determine capability with our variety of detanglers.

What do I need, a spring detangler or a spring coiler?

Everything depends on the amount of springs you use per shift or your required spring output and how often the problems arise due to tangled springs. When buying springs from a spring manufacturing company, the manufacturer’s costs for labor, administration, taxes etc are included in the price you pay. With a Spring Coiler you will only pay as much for a spring as the amount of wire that is used to manufacture it. This often means that you can save up as much as to 75% of your annual spring costs by investing in one of our spring coilers.

With a yearly spring need of 10 million springs and a spring price of 0.01 per spring, the yearly savings from investing in our coiler could reach $ 75 000.

Even further cost reductions can be made by the fact that our coilers will reduce labor and storage costs, minimize scrap rates and allow a more flexible production.

What is a CNC Based spring coiler?

The CNC-based coilers use servo motors and servo drives to ensure stable and smooth motions that can easily be programmed. Between one and three servo axes are used to control the coiler's motions. The number of axes depends on the type of coiler that is used and the type of spring that is being manufactured.

Our CNC-based spring coilers have been designed to offer an even more stable coiling process by making it possible to use a the full range of post manufacturing options.

(Back to Top)

What are the advantages of a CNC based spring coiler?

There are many advantages with a CNC-based coiler:

  • Unlimited wire feed
  • All post manufacturing options can be used
  • One coiler can be programmed to manufacture numerous different types of springs
  • Change over time between different springs can be extremely short
  • The ability to receive production statistics
  • The ability to use the feedback options

What are the advantages of laser marking compared with other options included PAD printing?

The advantages in laser marking technology are a permanent marked part and free of any consumptions costs (ink, pads, cartridges of any ink etc) and inventory advantages which make easier tracking and identification marks.

This machinery can be used in fully automated production lines 24/7 without maintenance breaks.

Also, because of the extremely fine laser beam quality of our Laser markers, font heights of 0.2 mm are possible as well as very fine details for logos, barcodes, UID marks, etc...

What are the industries that use this technology for marking processes?

* Electronic industry 
The manufacturers of electronics need a permanent mark in their products that it doesn't change the physical characteristics of their products. Laser marking is the answer to this and other needs.  
 
The typical electronic parts that can be marked are plastic connectors, audio panels, amplifiers, disks, wafers, IC (integrated Circuit) packages, mini circuits, Plastic (ABS) housing for telecom devices, keyboards, etc. 
Direct part marking of PCBs: no need to apply any colors or chemical agents and done without even penetrating the solder stop layer.   
 
* Industrial applications 
The companies mark their products to increase the recognition of their marks, tracking of products, inventory matters, security and identification of parts, to mention only a few examples.  
 Mark plastics, creating color changes by removing finishing layers. Mark metals and ceramics by engraving or, steel by annealing. Use the barcode library to get machine readable serialization in one or two dimensions. Even enhance the appearance of your products by decorating them with imported graphics or photorealistic grayscale bitmaps. All of this can be done with short cycle times and without sacrificing quality for quantity.  
The industrial parts that typically can be marked are boring tools, ID labels, logos of companies, machinery specification, posters, etc.    
 
* Jewelry industries
Our Laser Marker is a good solution for axially-directed engraving of rings, with high resolution and precision. 
 
* Automotive industry 
Today's automotive industry makes particular use of laser marking in production for functional and ornamental parts of cars and its components. The components used for operative purposes are marked to instruct the driver how to operate them. The parts installed to add an aesthetic touch to a vehicle sometimes come printed with informative texts.
Day-night design: Back lighted symbols for automotive interiors. High quality requirements are easily met, reproducibility and process stability better than 5 ppm.
 
* Aerospace industry  
Many aerospace components need a permanent identification that doesn't affect the material characteristics or the finish of the surface. The feature of the touch-less bundled light beam is the only marking option that can produce permanent images without compromising the integrity of the components.  
 
The aerospace parts that typically can be marked are fuel kit, back panels, cable connectors of spaceships, aerospace harness, fuel nozzle, control assembly, light panels and control panel, flow valves, missile parts, windows for spaceship cockpits, helicopter parts, etc.
