Our safety window can easy to see-through as it's highly transparent.
The strength of anti-strike is stronger 250 times than tempered glass and 30 times than acrylic.
Simple construction, light weight and silicon sealant so it's easy to install.
All kinds of size and shape are available depends on your requirement.
Abundant experience
The machine tools manufacturers in Taiwan, for example:
  VICTOR, YANG IRON, FAIRFRIEND, CHEVALIER, TAKANG, KAO-MING, TONG-TAI, HARDINGE, ETC.
The extra necessary for jewelry store and public construction¡K,etc.

  The specifications of safety
The results of polycaarbonate strength tested by I-ZOD.
 
V-Type(notched)@3m/m thick ASTM D256A 12-16ft-lbs/in
Non V-Type@3m/m thick ASTM D256A 60ft-lbs/in
The strength of falling ball: @6m/m thick GE test>200ft-lbs/in
Polycarbonate is fire-proof.
It won't cause anydanger as it won't break or shatter.
Pass tested by TUV used on CNC machine center and NC lathe are suitable.
Flexible design for any size
Any size is available according to customer demand. Are or streamline shape is also available.



  Glass + Polycarbonate
The advantage of glass is it's high photic rate and superior surface hardness. Furthermore, polycarbonate has strong power of anti-strike and high photic rate. Combining the both advantages will be a irreplaceable safety window.
It's now a precision, correct and efficiency epoch, the spindle speed of machine tool is getting higher and higher speed. It's be dangerous that the work piece or jaw may spurt out, so our safety window can is the best choice to protect the person.
To install our safety window on CNC lathe or CNC machine center can protect the person who is operation the machine and can avoid some dangerous.
The best design of anti-condensation
Condensation appearance won't happed with our distinctive technology.

* B size and C size have many kind of thickness to use.


  DERSTRONG PC safety window
It's the best plastic material to replace the acrylic, the anti-strike strength is 30 times than acrylic.
It can be arched in cold-formed, the minimum radius=thickness x 100
Any thickness is available depands on your demand.
It was approved by a test that can be processed in any shape with it's strong ductility.
The weight is only the half of glass, and easy to install.
The effect of sound-proof is good to obstruct the noise continuously outside.
  The effect of insulation is good, it can be used continuously in 89oC.
  It's kind of safe glass material as it won't break or shatter.
The safest material or your choice
  It's impact strength is 250 times than tempered glass, so it must be your best choice for the consideration of safety.




  DERSTRONG special safety window
The construction is combined with tempered glass and PC. The thickness tested by TUV is 12m/m pc+5m/m tempered glass. The tempered glass can endure energy is 8000 joule to strike it in the speed of 80M/sec. It was approved that our safety glass is suitable to use in CNC lathe and machine center.
As the high cutting speed in CNC machines, so it's dangerous that the chips spurt out. It won't be suitable to use a acrylic be the guard. Our company has researched in this special safety window for years. The main materials are glass, polycarbonate, and distinctive aluminium alloy, so the advantages are able to endure rub and anti-condensation.
The endure force of strike for DERSTRONG PC safety window
* Materials thickness:6m/m
Temperature Impact force Testing method
23oC >10.9kg-m/cm GE TEST
0oC >10.9kg-m/cm
-20oC >10.9kg-m/cm
* The testing result of a round ball diameter in 25m/m, weight in 2.27kg, fall    from the height of 12.2 meter.
