Urea-formaldehyde resin (UF), also known as urea-formaldehyde resin, is a polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acid catalyst) to form an initial urea-formaldehyde resin, and then under the action of a curing agent or auxiliary agent to form an insoluble and insoluble final stage Thermosetting resin. The cured urea-formaldehyde resin is lighter in color than phenolic resin, translucent, resistant to weak acid and alkali, has good insulation performance, excellent wear resistance, and is cheap. It is the most used type of adhesive, especially in the wood processing industry. In the manufacture of various wood-based panels, urea-formaldehyde resin and its modified products account for about 90% of the total amount of adhesives. However, urea-formaldehyde resin is easily decomposed in the presence of strong acid and strong alkali, and has poor weather resistance, poor initial viscosity, large shrinkage, high brittleness, water resistance, and easy aging. The wood-based panels produced with urea-formaldehyde resin have formaldehyde release in the process of manufacturing and use. problem, so it must be modified.

CNC quenching induction hardening machine tool has the following features:Â
  1, the machine uses PC-industrial digital control systems, high performance, debug and easy to use, to the greatest degree of quenching the workpiece to meet the complex needs.Â
  2, the machine can achieve quenching mode: continuous scan quenching, and quenching, sub-continuous scanning quenching (by the level of sub-setting, no limit switch, the same below), while sub-quenching.Â
  3, this machine is suitable for the typical artifacts (in the appropriate size range) axis: a variety of shaft, step shaft, gear shaft, cam shaft, axle, the cylindrical disk-type parts, end so on.Â
  4, the machine control system for reserve electrical heating and cooling water quenching control interface. According to the process of quenching process and the need to control the cooling process.Â

Applications of induction hardening machineÂ
:Heat Treatment (surface hardening/quench):
It is mainly aims to change the rigidity of the metal materials through the heat treatment to work pieces. Detail applications are stated as follows: Â
1. Hardening for various hardware and tools, such as plier, wrench, hammer, ax, screwing tools and shear (orchard shear).
2.Hardening for various automobile and motorcycle fittings, such as crankshaft, connecting rod, piston pin, chain wheel, aluminum wheel, valve, rock arm shaft, semi drive shaft, small shaft and fork.
3. Various electric tools, such as gear and axes.
4. Hardening for machine tools, such as lathe deck and guide rail.
5. Quench for various hardware metal parts and machined parts, such as shaft, gear (chain wheel), cam, chuck and clamp etc.
6. Quench for hardware molds, such as small-size mold, mold accessory and inner hole of mold.

FAQÂ
1. What's your MOQ?
For now, we have not yet strict policy about the quantity. Any quantity will be OK.
2. Can you send me similar video for my application?
Yes. We have many machine working onsite videos. Such as brazing, forging, hardening, shrink fitting, etc.Â
Also according to your your work pieces, we can send you similar video for reference.Sometimes, we can send the same work piece heating video,then,you will see the whole heating or production process.
3. I am new , about this product
It doesn't matter. We have experienced sales and professional engineer , communicated and guide you. We will design and recommend you the suitable machine model (power and frequency, coils). Usually, you just need tell us your work pieces' specifications and heating requirements, or detailed applications.
4. Can you make special coils for my work piece?
Yes. Usually we provide 2 piece of coils, together with the machine.
5. Can we have extra induction coils ?
Yes. We can tailor-made extra coils, if you need. While you only need pay very low cost,factory price.
