The manufacturing,quality testing and Packing

  • We established a rigorous quality test program, keeping the record of our customer’s drawings and samples.

  • Quality fast feedback during product making.

  • The piston and rod: the pistons,the seal,O-rings inspecting at random, the piston rod size, the hardness, rod finishing inspecting.

  • The tube: the cylinder tube cutting, chamfer, the size, tube inner finishing inspecting.

  • Assembling: the rod and the cylinder assembling, checking the piston with rod smoothly in the cylinder, the amount of the oil.

  • the gas spring was filling with nitrogen gas, force testing, 500N less pressure control range ± 15N, 500N more pressure is more control range± 20N.

  • After the surface treatment doing, painting, checking the paint.
  • The force testing again, checking the oil leakage, gas leakage.
  • The packing: every good product with one plastic bag, the label, warning signs, good cartons packed. Each carton weight is less than 20kgs.

  • The stocked:after all gas spring were finished, we move them into the stocked room, the piston rod of gas springs is in the lower level than the cylinder tube.

Quality control of gas spring test bench

  • Linear test stands
    Learn the force and stoke of gas spring and damping,so as to achieve to control the the performance of gas spring ,and produce better gas spring.
  • Salt spray test machine
    To do anti-corrosion surface treatment of gas springs, so as to meet customer’s using standard.
  • Fatigue testing machine
    To do fatigue testing of new varieties gas spring , extended service life of gas spring and improve product performance.
  • Water test bed
    To do water pressure test of gas spring, ensure each gas spring nitrogen gas does not leak, so as to ensure product quality.
