 Insulating rubber mat structure: 
 Insulation rubber pad with plastic type insulation materials. Male 
 Insulated rubber mat technology and molding: 
 Insulating pad under the surface there should be no harmful irregularities. Harmful irregularities is one of the following characteristics, namely, to destroy the uniformity of the smooth contour of the damaged surface defects such as holes, cracks, local uplift, incision, mixed with conductive particles, creases, the gap, the bump, ripple and casting marks . Harmless irregular surface irregularities formed in the production process. 
 Insulating rubber pad thickness: 
 Throughout the insulation mat should be randomly selected more than five different points for thickness measurement and inspection. You can use the micrometer or precision instruments to measure. Micrometer precision should be 0.02mm or less, measured drill the diameter of 6mm (3.17 ± 0.25) mm, the diameter of the plane pressure foot of the presser foot should be able to impose (0.83 ± 0.03) N pressure. Insulating pad should be flat to place, in order to make thousands tape measure is smooth. 
 Insulating rubber mats national standards:
