As more and more people travel, driving to the surrounding areas during small holidays has become an indispensable activity. Driving for a long time will lead to fatigue, and an ergonomic chair is needed. Points to note when making Chair Mold: 1. The steel material of the planting mold is generally P20 or 718 steel. 2. Gating method: 90% of Sino chair molds generally use side gates, and some use hot runners for large pouring mouth. 3. Demoulding method: the thimble is placed on the ribs, if the manipulator takes it out, it will move upwards, if it is automatically taken off, it will flip downwards. 4. Surface treatment: polishing, dermatoglyphics, regional dermatoglyphics. Flower plate interchange: generally use diagonal rods to knock out interchange, screw rotation interchange is more advanced. There are many types of injection molding chairs SINO molds, such as ordinary dining chairs, armchairs, chair backs, special seats for gyms or buses, child safety seats, small children chairs, beach lounge chairs, sofa chairs, flower board interchangeable chairs, etc. The above types of chairs are all Plastic Injection Mold that can be obtained by injection molding.
