Precision injection molding technology can be applied for the computer, communication, electric appliance and medical components industries. This paper presents a new design of a tiebarless clamping system for micro-injection molding machine. The tiebarless clamping system can provide lots of convenience, such as more mold space for automation etc., for a micro-injection molding machine. Good parallel precision between stationary platen and movable platen of a clamping system is an important feature for high precision injection molding. With special mechanism of this tiebarless clamping system, the movable platen will deform with the stationary platen synchronously under high clamping force to maintain the parallelism. Via tests and verifications, the parallel precision is controlled at good condition under 6 tons of clamping force.
