description2
Working Principle (Fully Automatic Cycle)
Start
The vacuum pump activates, and the vacuum chamber descends to trigger the limit switch.
Vacuuming
The vacuum valve opens, and the chamber evacuates to the preset vacuum level (regulated by pump capacity and duration).
Sealing
The sealing cylinder presses the heating element down, ensuring precise sealing with adjustable temperature.
Reset
The vent valve releases pressure, allowing the pneumatic cylinder to retract and the vacuum chamber to rise, completing the cycle.
Core Advantages
Material upgrade
The entire body is made of 304 stainless steel, and spectral detection ensures purity.
Process enhancement
Utilizing cold welding technology and a four-corner triangular angle iron frame, its stability far exceeds competitors using carbon steel.
Flexible adaptation
The machine supports switching between single-chamber (L type) and double-chamber (S type), covering diverse packaging needs from bulk food to large items.

The equipment features dual/triple/quad temperature zones with independent control, ensuring stable output and simplified troubleshooting. Each heating strip, with varying resistance, is powered by a dedicated transformer, and time relays optimize heating duration to guarantee secure seals and minimize defects.
Double-row self-aligning bearings enable automatic fine adjustment, ensuring the vacuum chamber and bedplate remain parallel to prevent air leakage.
Through independent R&D, we optimize the alloy composition by introducing multiple elements and adding tin to increase material thickness. This results in a softer texture for better flexibility, enhanced heat dissipation, and improved fracture resistance.
We use 304 stainless steel, while competitors rely on carbon steel. The equipment features a rigid frame structure secured with angle iron brackets for enhanced stability.
Constructed from 4-mm-thick stainless steel with six integrated reinforcing ribs, our equipment remains deformation-resistant and highly stable. In contrast, competitors' equipment often uses thinner materials, leading to slight bedplate deformation during vacuuming. This causes hard-to-detect air leaks.
Four connecting rods are simultaneously processed via mechanical positioning and punching, ensuring high precision and bearing protection. In contrast, other factories rely on manual dot-marking, hole-punching, and cutting with a meter ruler, resulting in significant errors and low precision. The guide post, connecting the connecting rod to the bedplate, features a precision-machined square structure to prevent uncontrolled rotation caused by circular designs.
Using an 8-mm-diameter steel spring, the gas cover remains lightweight, saving installation time and enhancing durability. In contrast, most competitors use 6-mm-diameter springs.
The sealing strip features closed-cell foam construction, is waterproof, damage-resistant, and designed for long service life."
