Company Advantages1. During the designing of DMS Seals , the designers make use of the plantar pressure scanner to investigate people's foot shape, hoping to create a product which best fits different people. We have developed solutions of the sealing of special working condition
2. Even though used for a long time, the product does not require frequent replacement due to its outstanding tightness and durability. DMS Seals takes the lead in grasping the development trend of the industry
3. The product features efficient dehydrating. The top and down structure is arranged reasonably to allow thermal circulation evenly to go through each piece of food on the trays. The R&D teams have the ability to design and develop seals for various of complicated working condition of sealing system
4. The product is leak-proof. Its good sealed seam can withstand a downpour and won't be compromised by the hot sun. DMS Seals' production equipment and test equipment are on the leading level in the industry
5. The product has a dramatically high color rendering index. It allows the colors of items to appear clear, vivid and distinguishable. DMS
o-ring seal has advanced machines and equipment for its production
