New and old microwave oven check list

Old type


New design


Transformer voltage variation

The circuit is complex, the maintenance is inconvenient, the failure rate is high, and the microwave emission efficiency is low

Variable pressure of oil cooled power supply

20%The structure is simple, easy to repair, not easy to fail, and the microwave emission efficiency is increased by 20%

Straight in waveguide

The microwave is easily reflected back to the magnetron, causing damage to the magnetron

A water loaded ring device is added to the waveguide

Effectively absorbs the reflected microwave to avoid damage to the magnetron

Waveguide tube homemade

The size accuracy is not enough, and it has some influence on the microwave efficiency.

Waveguide tube procurement with professional manufacturers

more accuracy, more use of microwave conduction

The cavity material is made of ordinary stainless steel

Microwave absorption is easy to absorb, and it affects microwave efficiency

The use of customized plate for the material of the cavity

It is not easy to absorb microwave and improve the microwave efficiency

Simple cavity structure

Microwave can not produce effective resonance in the cavity, which causes the wave to offset each other and reduces the microwave efficiency.

Design of the cavity according to the microwave emission law

The geometric design size is more beneficial to increase the number of resonant modes and to ensure a good match between the furnace cavity and the magnetron

Metal mesh bar + asbestos strip is used in door cover leakage protection device

Microwave leakage prevention is not very ideal

Leak proof device for door cover using high waterfall silicone strip coated wire and wave retaining device

The effect of anti microwave leakage is obvious

Microwave loss too much, waste of energy 

The overall microwave efficiency is 1.5 times higher than that on the original basis

——Microwave vulcanization production line and process technology——

——Product advantage—

  • Selection of industrial special waveguide tube accurate, more use of microwave conduction.
  • The material of the cavity is made of custom-made plate, which is not easy to absorb microwave and improves microwave efficiency.
  • The cavity is designed according to the law of microwave emission. The geometric design size is more conducive to increasing the number of resonance modes and ensuring a good match between the furnace cavity and magnetron.
  • Import and export use short-circuit ring + multi-segment resistance wave + silicon carbide resistance microwave, effectively stop the microwave leakage of import and export.
  • The anti-leakage device of door cover adopts high temperature resistant silicone strip coated wire+wave-blocking device, which has obvious anti-microwave leakage effect.
  • The shape frame adopts laser cutting iron plate folding type, which is beautiful and atmospheric.
  • The size of the internal structure is the same as that of the peers (6.8m). On this basis, it is extended to 8m, and the best vulcanization speed can be achieved by combining hot air with microwave more effectively. In addition, vulnerable parts of conveyor belt are also common with vulcanization equipment, which provides convenient conditions for customers to produce.
  • Microwave control system can achieve constant output of microwave power. Even if one group of microwave fails, it can also distribute its power to the other groups, so that the microwave output power can be constant and the effect of microwave on product vulcanization can be avoided.
