Resistant to impact all aluminum aluminum oxide, aluminum edging width 35mm, thickness 2mm not all about aluminum oxide, aluminum edging width 30mm, thickness of about 1mm cushioning material all with new materials production of new cotton, good elasticity, shock effect reaches II level, multi-use EVA cotton. Sponge full with the old material production EVA, elastic good, more choice and EPE high foam. Hardware-plated hardware of all branded products, good work intensity, pumping hands with a 10mm diameter, multi-branded hardware plating process in the workshop, work intensity difference, pumping hands with 8MM products, wheels with 3.5-inch or 4-inch dual-bearing poly Grease wheel loads up to 150KG / or selection of strengthening performance load reach 200KG / or more wheel plate thickness of 4mm thick. A 3-inch small single bearing wheel or the use of PVC plate thickness of 2mm, load no more than 80KG / just below the bottom multi-use 15mm or 18mm more use of the entire board 9mm or 12mm plate rivet distance is usually about 200 at 100mm above the platen Process panels and boards generally use white latex adhesive, pressure 12-24 hours at a temperature of 100 degrees is not sparkling, not wrinkled panels and boards generally with yellow glue, laminated and non-laminated, may in strong light irradiation blistering, wrinkling regular service factory service for lifelong maintenance free warranty for one year or more family cottage factory air box without service in Inner Mongolia, a quality problem can not be solved other precision workmanship, good hand, pipeline production, tightness, precision products can be used more than five years (touring nature of the use) rough, hand-poor, poor sealing cottage, accuracy is poor, most products a year (touring of use) Consumer who at the time of purchase travel suitcase Shanxi factory air box, first check the appearance of the box, that box is Zhou Zheng, box angle is symmetrical, the box can be upright or upside down on the ground to check the box if fours, not skew, and see me face is smooth, with or without scratches, cracks, with particular attention to case (above, below) should be symmetrical corners. Open the box air box manufacturer, check the tank port factory air box, box opening to coincide with each other, the gap should be small, to seam, hinge rotation flexibility, no obstruction, kema (buckle) and combine, the deduction is maintained , hit the open, the box should be adhered firmly, textile fabrics may not have jump wire, split horses phenomenon. Handle (mop) installation firm, not loose. Retractable rod should have a certain strength, telescopic rod with fixing lever with moderate, not too large volume expansion, after locking lever button is pressed, should be able to shun local telescopic rod. Me to go round should be flexible rotation, the best choice to go round with a bearing. Check the box lock, you can easily combine several sets of digital test, open, closing the normal can be.
