This customer develops control devices for automobiles worldwide and they use Spanclamps Quarter Turn Fasteners on assembly fixtures for motor actuators.

In the process of assembling the bracket to the actuator, they use four types of dedicated fixtures. The operator needs to change the fixtures every time the actuator to be assembled changes. They used to clamp the fixtures with wing screws, but it was not only troublesome to turn the screws many times, but also time-consuming to find the removed screws when they were lost.

A manufacture of intercom and fire alarm for home use Spanclamps Quarter Turn SCQT on injection molding line for the resin products. They cut the resin burr on back of the post-molded products by a nipper.

Setups for changing the nipper and its position come out every mold change because the position of the burr is different product by product. In the previous line, they used the general-purpose nipper units for all products and it took more than 15 minutes to loosen screws, change nippers and adjust positions. They needed to change the mold more than 50 times per month for some machines.

A manufacturer of meat processing equipment, uses the Retractacle Quarter Turn to change the hands on their brand-new "Scorpion" an automated meat packaging machine. Scorpion automatically puts aligned slices of meat on food trays. The hands that carry the meat slices to the tray have to be changed at least once a day, when the shape of the meat slice is changed or for cleaning and maintenance.

QUESTIONS

I have a project with company who are specialized on produce medical implants for visceral and spinal surgery.
Their products are made by thermo molding. They're looking to save changeover time with the heavy-duty retractable fasteners.
 
SCQTRHD0620 + SCRHDBI
 
As it is a heat molding process, the fastener would be subjected to continuous heat for 7h/day.
150°C or a little more.
 
With the continuous heat, can the fastener be damaged quickly?
Could the mechanism get stuck?
 
Have you done a heat test on these bindings?
I see 180°C in the catalogue.
Is it the max or do you have safety coefficient?

TECHNICAL ADVISES

it's quite costly, but it can be always done.

here are some processes that increase the cost:

- Electro polishing for reducing friction and particles
- Kolsterising for preventing galling
- Cleanroom packaging for minimizing contamination
- Rerolled thread Ag or Au plating on request

In the semiconductor industry, printing and etching processes require cleanness and lubricant is not acceptable but other processes done in normal air like testing and handling can accept our fasteners.

In the food industry, we are aiming to applications under the pass-line that do not touch the food directly.

We have made custom fasteners with a special vacuum lubricant for some semiconductor customers, but the quantity should be big.  (project investment of 25000-50000 euro)

In the machining process, as the tool cuts off the unnecessary material from the workpiece, a cutting force will be generated on the workpiece. To resist the cutting force and allow the cutting process to be completed, the workpiece must be firmly clamped on the machine tool. The device that positions and clamps the workpiece is called a fixture. The device that holds and guides the cutting tool is called jigs.

We love to hear (and see) how our parts are used. Thanks for the great video!

"We use Spanclamps for our project ‘’Continental’’.
It is a PSB mounting application in plastic housing using an electric press. There are three reasons why we need interchangeable nests.
We chose Anemo for precision centering and fixing."

See it for yourself:

A major worldwide manufacturer of off the shelf switch mode power supplies used to use self-produced clamps for clamping two plates.

Their production line was shut down a lot for repairing damaged clamps due to heat hardening.

Since they use quarter-turn fasteners, they reduced costs (by 70%!) and the clamps are maintenance-free (for over 2 years now)!

Your company manufactures machine parts, and you use fixtures of automated production machines to mount screws to the machine part body. Have you ever considered using ball lock clamps and button lock pins?

Many applications require "changeovers" that involve changing and replacing about 10 times a day, as a machine produces many products of different shapes and sizes.

Consider the benefits by using One-Touch Fasteners.

Less workload = less cost!

One of our customers was looking for a way to safely secure the tooling of a cutting machine while it was running. Besides that, the tooling also needs to be changed sometimes, and it has to be done in a minimum of time.

SpanClamps can meet up to those two requirements. By using SpanClamps you are sure that the tooling is safely secured, and with just a simple quarter-turn the tooling can be removed. So, changeover is reduced to a minimum.

In the designs below, you see how SpanClamps are used with this project:

Here you can see the part SCQTHD0620 used

Here you can see the receptacle SCRHDBI installed.
